- This web service layer group contains multiple layers at various scale dependencies which enhances the cartographic display of ecoregion data. Each layer depicts ecoregion features drawn at specific scales as detailed in the layer name. IMPORTANT information regarding proper legend rendering in ArcMap: Due to the limitations of Graphical Device Interface (GDI) resources per application on Windows, ArcMap does not display the legend in the Table of Contents for the ArcGIS Server service layer if the legend has more than 100 items. As of December 2011, there are 968 unique legend items in the Level IV Ecoregion Polygon legend. Follow this link (https://support.esri.com/en/knowledgebase/techarticles/detail/33741) for instructions about how to increase the maximum number of ArcGIS Server service layer legend items allowed for display in ArcMap. Note the instructions at this link provide a slightly incorrect path to "Maximum Legend Count". The correct path is HKEY_CURRENT_USER > Software > ESRI > ArcMap > Server > MapServerLayer > Maximum Legend Count. When editing the "Maximum Legend Count", update the field, "Value data" to 1000. To download a PDF version of the Level IV ecoregion map and legend, go to ftp://ftp.epa.gov/wed/ecoregions/us/Eco_Level_IV_US_pg.pdf. Please read the remainder of this layer description for general information about Level IV Omernik Ecoregions. This layer represents Level IV Omernik Ecoregions. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. Compilation of the level IV maps, performed at 1:250,000 scale, has been a part of collaborative projects between US Environmental Protection Agency, National Health and Environmental Effects Laboratory (NHEERL)--Corvallis, OR, the US Forest Service, Natural Resources Conservation Service, and a variety of other state and federal resource agencies. The ecoregions and subregions are designed to serve as a spatial framework for environmental resource management. The most immediate needs by the states are for developing regional biological criteria and water resource standards, and for setting management goals for nonpoint-source pollution. Level IV ecoregions are intended for large geographic extents (i.e. states, multiple counties, or river basins). Use for smaller areas, such as individual counties or a 1:24,000 scale map boundary, is not recommended. Explanation of the methods used to delineate the ecoregions are given in Omernik (1995), Griffith et al. (1994), and Gallant et al. (1989).

- The file geodatabase (fgdb) contains the Sea, Lake, and Overland Surge from Hurricanes (SLOSH) Maximum of Maximums (MOM) model for hurricane categories 2 and 4. The EPA Office of Research & Development (ORD) modified the original model from NOAA to fit the model parameters for the Buzzards Bay region. The models show storm surge extent for the Mattapoisett area and therefore the flooding area was reduced to the study area. Areas of flooding that were not connected to the main water body were removed. The files in the geodatabase are: Cat2_SLR0_Int_Feet_dissolve_Mattapoisett: Current Category 2 hurricane with 0 ft sea level rise Cat4_SLR0_Int_Feet_dissolve_Mattapoisett: Current Category 4 hurricane with 0 ft sea level rise Cat4_SLR4_Int_Feet_dissolve_Mattapoisett: Future Category 4 hurricane with 4 feet sea level rise The features support the Weather Ready Mattapoisett story map, which can be accessed via the following link: https://epa.maps.arcgis.com/apps/MapJournal/index.html?appid=1ff4f1d28a254cb689334799d94b74e214 days ago

- This data layer identifies the locations of Combined sewer overflow outfalls. Combined sewer systems are sewers that are designed to collect rainwater runoff, domestic sewage, and industrial wastewater in the same pipe. Most of the time, combined sewer systems transport all of their wastewater to a sewage treatment plant, where it is treated and then discharged to a water body. During periods of heavy rainfall or snowmelt, however, the wastewater volume in a combined sewer system can exceed the capacity of the sewer system or treatment plant. For this reason, combined sewer systems are designed to overflow occasionally and discharge excess untreated wastewater directly to nearby streams, rivers, or other water bodies.

The Total Maximum Daily Load (TMDL) Tracking System contained information on waters that are Not Supporting their designated uses. These waters were listed by the state as impaired under Section 303(d) of the Clean Water Act. The status of TMDLs were also tracked. TMDLs are pollution control measures that reduce the discharge of pollutants into impaired waters. A TMDL or Total Maximum Daily Load is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. Under Section 305(b) of the CWA, the states, territories, and other jurisdictions of the United States are required to submit reports on the quality of their waters to the U.S. Environmental Protection Agency (EPA) every 2 years.14 days ago

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions for the Mississippi Alluvial Plain were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. By recognizing the spatial differences in the capacities and potentials of ecosystems, ecoregions stratify the environment by its probable response to disturbance (Bryce and others, 1999). These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and non-government organizations that are responsible for different types of resources within the same geographical areas (Omernik and others, 2000). The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of the spatial patterns and the composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity (Wiken, 1986; Omernik, 1987, 1995). These phenomena include geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another regardless of the hierarchical level. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997).

Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989). This product is part of a collaborative effort primarily between USEPA Region VII, USEPA National Health and Environmental Effects Research Laboratory (Corvallis, Oregon), Mississippi Department of Environmental Quality, Arkansas Department of Environmental Quality, Arkansas Multi-Agency Wetland Planning Team (MAWPT), U.S. Army Corps of Engineers (USACE), U.S. Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS), U.S. Department of Interior - Fish and Wildlife Service (USFWS), and U.S. Department of Interior - U.S. Geological Survey (USGS) - Earth Resources Observation Systems (EROS) Data Center. The project is associated with an interagency effort to develop a common framework of ecological regions. Reaching that objective requires recognition of the differences in the conceptual approaches and mapping methodologies that have been used to develop the most common ecoregion-type frameworks, including those developed by the U.S. Department of Agriculture - Forest Service (USFS) (Bailey and others, 1994), the USEPA (Omernik, 1987, 1995), and the NRCS (United States Department of Agriculture - Soil Conservation Service, 1981). As each of these frameworks is further refined, their differences are becoming less discernible. Regional collaborative projects such as this one in the Mississippi Alluvial Plain, where agreement can be reached among multiple resource management agencies, are a step toward attaining consensus and consistency in ecoregion frameworks for the entire nation.

They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas.

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011).

- Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 105 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2011). Level IV ecoregions are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

- Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. The ecoregions of Alaska are a framework for organizing and interpreting environmental data for State, national, and international level inventory, monitoring, and research efforts. The map and descriptions for 20 ecological regions were derived by synthesizing information on the geographic distribution of environmental factors such as climate, physiography, geology, permafrost, soils, and vegetation. A qualitative assessment was used to interpret the distributional patterns and relative importance of these factors from place to place (Gallant and others, 1995). Numeric identifiers assigned to the ecoregions are coordinated with those used on the map of "Ecoregions of the Conterminous United States" (Omernik 1987, U.S. EPA 2010) as a continuation of efforts to map ecoregions for the United States. Additionally, the ecoregions for Alaska and the conterminous United States, along with ecological regions for Canada (Wiken 1986) and Mexico, have been combined for maps at three hierarchical levels for North America (Omernik 1995, Commission for Environmental Cooperation, 1997, 2006). A Roman numeral hierarchical scheme has been adopted for different levels of ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 50 regions. At Level III, there are currently 182 ecological regions for North America. Level IV ecoregions have been developed for the conterminous United States, but Level III is the highest level available for Alaska.

- The Human Well-being Index (HWBI) for U.S. counties is a set of nationally consistent demonstration results that may be used to characterize community well-being. This composite index was developed by U.S. EPA Office of Research and Development in support of its Sustainable and Healthy Communities (SHC) Research. It serves as an endpoint measure for use in the creation of community decision-support tools. The HWBI characterizes community conditions in the context of the flow of economic, social and ecological services. The index calculation approach used a nested-indicator design. A decade (2000-2010) of cultural, economic, and social data were drawn from publicly available sources (e.g., US Census, Bureau of Economic Analysis, American Community Survey, General Social Survey, Centers for Disease Control) to provide the foundation for well-being related indicators. Indicators are integrated into one of eight domains or sub-indices of well-being. These domains were synthesized to represent different aspects of well-being characteristics common across communities of all sizes. Service indicators reflect the availability of select socio-ecological services that influence well-being. Community decisions often result in changes in the flow of community services. Collectively, well-being and service measures provide a means to evaluate relationships between the availability of certain community services and overall well-being. Data used to generate service indicators were also collected from existing data sources. Detailed information about the attributes of the HWBI, its components and related service indicators are described in Indicators and Methods for Constructing a U.S. Human Well-being Index (HWBI) for Ecosystem Services Research (EPA/600/R-12/023. pp. 121) and Indicators and Methods for Evaluating Economic, Ecosystem and Social Services Provisioning (EPA/600/R-14/184. pp. 174), respectively.14 days ago
- Climate and land-use change are major components of global environmental change with feedbacks between these components. The consequences of these interactions show that land use may exacerbate or alleviate climate change effects. Based on these findings it is important to use land-use scenarios that are consistent with the specific assumptions underlying climate-change scenarios. The Integrated Climate and Land-Use Scenarios (ICLUS) project developed land-use outputs that are based on a downscaled version of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) social, economic, and demographic storylines. ICLUS outputs are derived from a pair of models. A demographic model generates county-level population estimates that are distributed by a spatial allocation model (SERGoM v3) as housing density across the landscape. Land-use outputs were developed for the four main SRES storylines and a baseline ("base case"). The model is run for the conterminous USA and output is semi-decadally for each scenario to 2100. In addition to housing density at a 1 hectare spatial resolution, this project also generated estimates of impervious surface at a resolution of 1 square kilometer.04 days ago

- Subtitle I of the Resource Conservation and Recovery Act, as amended by the Hazardous Waste Disposal Act of 1984, brought underground storage tanks (USTs) under federal regulation. As part of that regulation, Congress directed EPA to develop financial responsibility regulations for UST owners and operators. Congress wanted owners and operators of underground storage tanks (USTs) to show that they have the financial resources to clean up a site if a release occurs, correct environmental damage, and compensate third parties for injury to their property or themselves. Owners and operators have several options: obtain insurance coverage from an insurer or a risk retention group; demonstrate self-insurance using a financial test; obtain corporate guarantees, surety bonds, or letters of credit; place the required amount into a trust fund administered by a third party; or rely on coverage provided by a state financial assurance fund. Information in this data asset includes state documentation to support this requirement. Many states have developed financial assurance funds to help owners and operators meet financial responsibility requirements and to help cover the costs of cleanups. State financial assurance fund programs, which supplement or are a substitute for private insurance, have been especially useful for small-to-medium sized petroleum marketers. EPA requires its Regional Offices to conduct annual reviews of state financial assurance funds. Data is provided by states, and reviewed by EPA, to determine financial soundness as follows: 1. How quickly each state's fund is reducing its federally-regulated, fund-eligible cleanup backlog. 2. Whether the fund currently has enough resources to address its backlog. 3. Whether the fund will continue to have adequate resources to continue to reduce its backlog in the future. 4. Whether there are any major or pending changes to the fund. EPA has the option of withdrawing fund approval, in which case the Agency works with the state to ensure that UST owners and operators have obtained an alternative financial responsibility mechanism. All documentation for these reviews, and subsequent decisions and actions, are maintained at the Regional Offices.04 days ago

- Subtitle I of the Resource Conservation and Recovery Act, as amended by the Hazardous Waste Disposal Act of 1984, brought underground storage tanks (USTs) under federal regulation. EPA implements the underground storage tank (UST) program in Indian country, providing support to tribal governments to prevent and clean up petroleum releases from USTs. The UST program in Indian country includes marketers and nonretail facilities that have USTs. Marketers include retail facilities such as gas stations and convenience stores that sell petroleum products. Non-retail facilities include those that do not sell petroleum products, but may rely on their own supply of gasoline or diesel for taxis, buses, limousines, trucks, vans, boats, heavy equipment, or a wide range of other vehicles. Of the more than 560 federally recognized tribes about 200 have federally-regulated underground storage tanks on their lands. Of those 200 tribes, over half have 10 or fewer active underground storage tanks. About 20 tribes have 30 or more underground storage tanks. Data on sites managed by this program is assembled by the EPA Regional Offices and varies from region to region in scope and content. Not all regions include Indian Nations. Publicly available data is limited to Excel spreadsheets, but regional contacts are also available to answer questions about the data. Data is updated in May and November of each year.14 days ago

- The State Authorization Tracking System (StATS) is an information management system designed to document the progress of each state and territory in establishing and maintaining RCRA-authorized hazardous waste management programs. StATS tracks the status of each state with regard to changes made to the federal hazardous waste regulations. The pages listed at the website show state authorization and adoption information for RCRA Subtitle C hazardous waste rules. Adoption information is based on data received from EPA regional offices. Currently, state authorization and adoption percentages are based on the required rules promulgated through RCRA Cluster XXII. Published federal register notices are the only legal mechanism by which EPA grants authorization to the states. If any of the information contained in the StATS database conflicts with information stated in the Federal Register, the Federal Register information will take precedence. We strongly recommend that the regulated community contact their state government office for hazardous waste regulatory information.14 days ago

- This asset includes hazardous waste information, which is mostly contained in the Resource Conservation and Recovery Act Information (RCRAInfo) System, a national program management and inventory system addressing hazardous waste handlers. In general, all entities that generate, transport, treat, store, and dispose of hazardous waste are required to provide information about their activities to state environmental agencies. These agencies pass on that information to regional and national EPA offices. This regulation is governed by the Resource Conservation and Recovery Act (RCRA), as amended by the Hazardous and Solid Waste Amendments of 1984. RCRAInfo Search can be used to determine identification and location data for specific hazardous waste handlers and to find a wide range of information on treatment, storage, and disposal facilities regarding permit/closure status, compliance with Federal and State regulations, and cleanup activities. Categories of information in this asset include: -- Handlers -- Permit Information -- GIS information on facility location -- Financial Assurance -- Corrective Action -- Compliance Monitoring and Enforcement (CM&E)04 days ago
- The United States Environmental Protection Agency (EPA), in cooperation with the States, biennially collects information regarding the generation, management, and final disposition of hazardous wastes regulated under the Resource Conservation and Recovery Act of 1976 (RCRA), as amended. Collection, validation and verification of the Biennial Report (BR) data is the responsibility of RCRA authorized states and EPA regions. EPA does not modify the data reported by the states or regions. Any questions regarding the information reported for a RCRA handler should be directed to the state agency or region responsible for the BR data collection. BR data are collected every other year (odd-numbered years) and submitted in the following year. The BR data are used to support regulatory activities and provide basic statistics and trend of hazardous waste generation and management. BR data is available to the public through 3 mechanisms. 1. The RCRAInfo website includes data collected from 2001 to present-day (https://rcrainfo.epa.gov/rcrainfoweb/action/main-menu/view). Users of the RCRAInfo website can run queries and output reports for different data collection years at this site. All BR data collected from 2001 to present-day is stored in RCRAInfo, and is accessible through this website. 2. BR data files collected from 1999 - present day may be downloaded directory in zip file format from (https://rcrapublic.epa.gov/rcra-public-export/?outputType=Fixed or https://rcrapublic.epa.gov/rcra-public-export/?outputType=CSV). 3. Historical data collected prior to 1999 may be ordered on CD. Please see contact information in this metadata file to order historical BR data. BR data are typically published in December of the year following their collection. Data must be received by authorized states and EPA regions if a state is not authorized to implement the BR program by March 1st of the year following collection, and are usually published in December of the year following collection. For example, data collected in 2001 would be received by states and EPA regions by March 1, 2002 and states and EPA regions compile the BR data submitted by facilities and load the state data set into RCRAInfo, the system which EPA Headquarters (HQ) manage. Then EPA HQ published the data files around December 2002. Additional information regarding the biennial report data is available here: https://rcrapublic.epa.gov/rcra-public-export/rcrainfo_flat_file_documentation_v5.pdf and here: https://www.epa.gov/hwgenerators/biennial-hazardous-waste-report.

- This GIS dataset contains polygons depicting RCRA Corrective Action boundary features from all EPA Regions. The Resource Conservation and Recovery Act (RCRA), among other things, helps ensure that wastes are managed in an environmentally sound manner so as to protect human health and the environment from the potential hazards of waste disposal. EPA and 44 authorized states and territories run the Resource Conservation and Recovery Act (RCRA) Corrective Action program to work with hazardous waste facilities to investigate and clean up any release of hazardous waste into the soil, ground water, surface water and air. In general, all generators, transporters, treaters, storers, and disposers of hazardous waste are required to provide information about their activities to state environmental agencies. These agencies, in turn pass on the information to regional and national EPA offices. Accidents or other activities at facilities that treat, store or dispose of hazardous wastes have sometimes led to the release of hazardous waste or hazardous constituents into soil, ground water, surface water, or air. When that happens, the RCRA Corrective Action program is one program that may be used to accomplish the necessary cleanup. This data set provides boundaries for those areas where cleanup activities are underway. RCRA CABs and cleanup boundaries are meant to include the various boundaries associated with a site, including: institutional controls, engineering controls, land use controls, anticipated/acceptable use limitations, operable units, as well as the site or facility boundaries.04 days ago
- This data layer provides access to Recovery Act Funded Cleanup sites as part of the CIMC web service. The American Recovery and Reinvestment Act was signed into law by President Obama on February 17th, 2009 and all reporting on ARRA for these 3 programs was complete as of 2013. Out of the five EPA programs that distributed recovery act funding, three of them were cleanup programs: Brownfields, Superfund and Leaking Underground Storage Tanks. CIMC provides information on site cleanups that received ARRA Recovery Act funding for Superfund and Brownfields, but not Leaking Underground Storage Tanks. Data for Brownfields came from the ACRES database. Data for Superfund came from the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) database. Data in CIMC no longer need to be updated for the ARRA program. For information on all EPA Recovery Act funded work, please see: http://archive.epa.gov/recovery/web/html/ and https://epamap17.epa.gov/arra/.14 days ago
- This data layer provides access to Removal/Response sites as part of the CIMC web service. Removals are hazardous substance releases that require immediate or short-term response actions. These are generally addressed under the Emergency Response program and are initially tracked centrally by the federal government's National Reporting Center. Cleanups in My Community maps and lists removals that are included in EPA’s epaosc.org site, and provides direct links to information on these sites. CIMC obtains updated removal data through a web service from epaosc.org twice a month. The CIMC web service was initially published in 2013, but the data are updated twice a month.

- This data layer provides access to Hazardous Waste Corrective Action sites as part of the CIMC web service. Hazardous waste is waste that is dangerous or potentially harmful to our health or the environment. Hazardous wastes can be liquids, solids, gases, or sludges. They can be discarded commercial products, like cleaning fluids or pesticides, or the by-products of manufacturing processes. The RCRA Corrective Action Program, run by EPA and 43 authorized states and territories, works with facilities that have treated, stored, or disposed of hazardous wastes (TSDs) to protect public health and the environment by investigating and cleaning up hazardous releases to soil, ground water, surface water, and air at their facilities. RCRA Corrective Action sites in all 50 states and four U.S. territories cover 18 million acres of land. EPA estimates that more than 35 million people, roughly 12 percent of the U.S. population, live within one mile of a RCRA Corrective Action site (based on the 2000 U.S. Census). RCRA Corrective Action facilities include many current and former chemical manufacturing plants, oil refineries, lead smelters, wood preservers, steel mills, commercial landfills, and a variety of other types of entities. Due to poor practices prior to environmental regulations, Corrective Action facilities have left large stretches of river sediments laden with PCBs; deposited lead in residential yards and parks beyond site boundaries; polluted drinking water wells in rural areas with chlorinated solvents; tainted municipal water supplies used by millions; and introduced mercury into waterways, necessitating fish advisories. At these sites, the Corrective Action Program ensures that cleanups occur. EPA and state regulators work with facilities and communities to design remedies based on the contamination, geology, and anticipated use unique to each site. Note: RCRA facilities which are not undergoing corrective action are not considered “Cleanups” in Cleanups in My Community. The complete set of RCRA facilities can be accessed via the EPA RCRA database in Envirofacts (https://www.epa.gov/enviro/rcrainfo-overview). The CIMC web service was initially published in 2013, but the data are updated twice a month.

- Federal facilities are properties owned by the federal government. This data layer provides access to Federal facilities that are Resource Conservation and Recovery Act (RCRA) sites as part of the CIMC web service. The Resource Conservation and Recovery Act, among other things, helps ensure that wastes are managed in an environmentally sound manner so as to protect human health and the environment from the potential hazards of waste disposal. In particular, RCRA tightly regulates all hazardous waste from "cradle to grave." In general, all generators, transporters, treaters, storers, and disposers of hazardous waste are required to provide information about their activities to state environmental agencies. These agencies, in turn pass on the information to regional and national EPA offices. Accidents or other activities at facilities that treat, store or dispose of hazardous wastes have sometimes led to the release of hazardous waste or hazardous constituents into soil, ground water, surface water, or air. When that happens, the RCRA Corrective Action program is one program that may be used to accomplish the necessary cleanup. In Cleanups in My Community, you can map or list RCRA Corrective Action sites that are currently undergoing corrective action, sites for which a remedy has been selected, sites for which construction has been completed, and sites where the corrective action cleanup is complete. This data layer shows those RCRA sites that are located at Federal Facilities. Note: RCRA facilities which are not undergoing corrective action are not considered “Cleanups” in Cleanups in My Community. The complete set of RCRA facilities can be accessed via the EPA RCRA database in Envirofacts (https://enviro.epa.gov/facts/rcrainfo/search.html).

- This data layer provides access to Brownfields Properties as part of the CIMC web service, although the data are generally more broadly applicable. Brownfields are real properties, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these properties takes development pressures off of undeveloped, open land, and both improves and protects the environment. CIMC provides information on Brownfields properties for which information is reported back to EPA, as well as areas served by Brownfields grants programs. Brownfields properties may be mapped or listed, and property profiles can be accessed from either maps or lists. There are many properties that meet the definition of a brownfield but are not funded by our program. They may be funded by states, localities, private or non-profit entities. The Brownfields data are reported by grant recipients via the ACRES database and updated and stored in Envirofacts monthly. For more information on the data updates to Envirofacts, please visit the Envirofacts Data Update page. For more information on the data provided through this webservice, please see the processing steps below, and see more information here: https://www.epa.gov/cleanups/cimc-about-data#brownfieldsp.

- This data layer provides access to Superfund National Priority List Sites as part of the CIMC web service. Superfund is a program administered by the EPA to locate, investigate, and clean up worst hazardous waste sites throughout the United States. EPA administers the Superfund program in cooperation with individual states and tribal governments. These sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills - the key word here being abandoned. Only NPL sites have been included in Cleanups in My Community thus far. EPA maintains the NPL, which identifies for the States and the public those sites or other releases that appear to warrant remedial (long term) actions. These NPL sites fall into the following categories: Proposed: Sites may be proposed for the NPL and then may be placed on the NPL as final or be removed from the Proposed NPL. Final: Those sites placed on the NPL are called "final," and for these sites, a cleanup remedy is selected and implemented. However, it may be several years after construction of the remedy is completed before the hazardous substances are completely cleaned up or controlled in place. Deleted: After the clean up process is complete, and appropriate reviews confirm the area is cleaned up or the hazards are controlled, sites can be deleted from the NPL. For more information on the data provided through this web service, please see the processing steps below, and see more information here: https://www.epa.gov/cleanups/cimc-about-data#superfund.

- This data layer provides access to Base Realignment and Closure (BRAC) Superfund Sites as part of the CIMC web service. EPA works with DoD to facilitate the reuse and redevelopment of BRAC federal properties. When the BRAC program began in the early 1990s, EPA worked with DoD and the states to identify uncontaminated areas and these parcels were immediately made available for reuse. Since then EPA has worked with DoD to clean up the contaminated portions of bases. These are usually parcels that were training ranges, landfills, maintenance facilities and other past waste-disposal areas. Superfund is a program administered by the EPA to locate, investigate, and clean up the worst hazardous waste sites throughout the United States. EPA administers the Superfund program in cooperation with individual states and tribal governments. These sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills - the key word here being abandoned.

CIMC taps into data publicly available from EPA's Facility Registry Service (FRS) - RCRA Corrective Action facilities, Brownfields properties and grant areas, Superfund NPL sites, other facility data) and web services (water monitoring stations, impaired waters, emergency responses, tribal boundaries, congressional districts, etc.) - and connects to other applications (e.g., Superfund's Public User Database, ACRES, RCRAInfo, etc.) to provide easy seamless access to site-specific cleanup information with explanatory text and within the context of related data. Data can be filtered by cleanup program, geography, environmental indicators, controls, and cleanup stage. CIMC also provides some web services that integrate these data for others to use in their applications.14 days ago
- The Trace Atmospheric Gas Analyzer (TAGA) buses are self-contained mobile laboratories that conduct instant-result monitoring of air quality at particular locations. In response to the BP Spill in 2010, equipment in the TAGA buses monitored for air toxics known as volatile organic compounds (VOCs). The specific VOCs being monitored were benzene, toluene, and xylene. These substances are also associated with facilities such as gas stations, oil refineries, paper mills, and autobody shops. The TAGA monitoring found that these substances are not present or are being detected at low levels in the areas monitored along the Gulf Coast and in New Orleans, LA. The levels found were well below levels that would cause temporary discomfort, irritation, or other minor effects.14 days ago
- The Office of Emergency Management maintains information relevant to preventing emergencies before they occur, and/or mitigating the effects of emergency when they do occur. A principal element of this data asset is the information managed by the System for Risk Management Plans (SRMP), which compiles risk management plans submitted by facilities in accordance with the Clean Air Act, Section 112(r). Affected facilities are to develop risk management programs which will prevent and minimize consequences of accidental releases of certain hazardous chemicals that could harm public health and the environment. Another component of this data asset are the results generated by the Priority Assessment Model (PAM), which analyzes information concerning low-level chronic emissions from facilities and sets priorities (low, medium, high) for proactive controls on releases that do not necessarily pose imminent threats, but which may under adverse circumstances create unacceptable health or ecological risks. Also included are inspection records compiled by the Oil Inspection Program. Under the Clean Water Act Section 311, EPA regulates oil storage that meets a specific regulatory threshold. Facilities that store oil and meet the regulatory threshold need to prepare and implement a Spill Prevention, Control, and Countermeasures (SPCC) Plan which needs to be reviewed and approved by a professional engineer. Additionally, facilities with larger oil storage capacity may have to prepare and implement a Facility Response Plan. EPA is the lead federal response agency for oil spills occurring in inland waters. All other information that contributes to EPA's programs, policies and guidance concerning the prevention and mitigation of emergencies is included in this data asset.04 days ago
- The Office of Emergency Management compiles a wide variety of information in support of Emergency Preparedness, including certain elements of the System for Risk Management Plans (SRMP), a wide variety of training and guidance materials, inventories and readiness/O&M status of equipment and response personnel.

- The Office of Emergency Management retains records of all incident responses in which it participates. This data asset includes three major sources of information: (1) records maintained by the Regional Office On-Scene Coordinators, principally at the EPAOSC.org web site, (2) all records of incidents managed at the EPA National Response Center (NRC) at EPA Headquarters in Washington, DC and (3) records of responses to oil spills under the Clean Water Act, for which EPA is the oil spill response lead for inland waters. Regional response information is available through EPAOSC.org, but may also be stored elsewhere if the incident is of national significance. EPAOSC.org is a resource for On-Scene Coordinators to access, track and share information with OSCs throughout the country, but it also contains information open to the public. Incident-related environmental sampling data is maintained by the regional offices in the SCRIBE system. NRC records have been maintained in the Emergency Response Notification System (ERNS). This information is available to the public through the Right to Know Network (RTKnet.ombwatch.org). Incidents reported to NRC range from minor to serious, from an oil-sheen on water to a release of thousands of gallons. NRC reports are extensive, but also known to be incomplete, as many incidents are never reported, and those that are reported generally are not subject to verification.04 days ago

- The Trace Atmospheric Gas Analyzer (TAGA) buses are self-contained mobile laboratories that conduct instant-result monitoring of air quality at particular locations. From May 18-June 6, 2010, EPA’s TAGA buses monitored for the two chemicals found in the COREXIT dispersants that have the highest potential to get into the air in any significant amounts: EGBE (2-butoxyethanol) and dipropylene glycol monobutyl ether. In addition to being found in the COREXIT dispersants, these compounds are found in cleaning products and coatings. As a result, we have not beeen able to identify the source of the measured compounds. The TAGA buses detected very low levels of these chemicals in the air, at a limited number of the locations sampled along the Gulf Coast. The levels found were well below those that are likely to cause health effects, and suggest that the use of dispersants on the oil spill would not have a significant impact on air quality on land.14 days ago

- This asset includes all types of information regarding Brownfields grant programs that subsidize/support Brownfield cleanup. This includes EPA's Brownfields Program grant funding for brownfields assessment, cleanup, revolving loans, and environmental job training. Assessment grants provide funding for a grant recipient to inventory, characterize, assess, and conduct planning and community involvement related to brownfield sites. Revolving Loan Fund Grants enable States, political subdivisions, and Indian tribes to make low interest loans to carryout cleanup activities at brownfields properties. Cleanup grants provide funding for a grant recipient to carry out cleanup activities at brownfield sites. Environmental Workforce Development and Job Training Grants are designed to provide funding to eligible entities, including nonprofit organizations, to recruit, train, and place predominantly low-income and minority, unemployed and under-employed residents of solid and hazardous waste-impacted communities with the skills needed to secure full-time, sustainable employment in the environmental field and in the assessment and cleanup work taking place in their communities. Training, Research, and Technical Assistance Grants provide funding to eligible organizations to provide training, research, and technical assistance to facilitate brownfields cleanup. Regulatory authority for the collection and use of this information is found in the Small Business Liability Relief and Brownfields Revitalization Act of 2002 ("the Brownfields Law"), which amended the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980.04 days ago

- This asset includes the EPA Federal Agency Hazardous Waste Compliance Docket (Docket), which is required by Section 120(c) of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The Docket contains information reported to EPA by federal facilities that manage hazardous waste or from which hazardous substances, pollutants or contaminants have been or may be released. The Docket serves three major purposes: 1. To identify all federal facilities that must be evaluated through the site assessment process to determine whether they pose a risk to human health and the environment sufficient to warrant inclusion on the National Priorities List (NPL); 2. To compile and maintain the information submitted to EPA on such facilities under the provisions listed in section 120(c) of CERCLA; and 3. To provide a mechanism to make the information available to the public. The docket includes facilities which have provided information to EPA through documents such as reports under a Federal agency environmental restoration program, regardless of the absence of section 103 reporting. E-Docket is an internal business management tool that will improve the tracking and record keeping of information about facilities that have been identified as potential Docket sites. The functionality of the system is basic record tracking, and it will contain a list of draft proposed facilities which can be sorted based on Agency ownership, region, or status (Draft Proposed, Proposed, Added, or Not Added). The information compiled in the tool is publicly available. The data asset also includes the FFRRO Regional Work Planning Application, which is a tool for the Superfund Federal Facilities Response Program. It collects regional site-specific planning targets for program measures. This data is entered by the regions and used by HQ to estimate and target program accomplishments.14 days ago

Information is provided about contaminated federal facility sites in specific communities, with access to technical fact sheets and tools and resources to help government agencies and their contractors fulfill cleanup obligations. EPA's federal facility information is easily accessible to ensure effective stakeholder involvement and accountability at federal facilities. Multiple federal statutes establish requirements for EPA and other federal agencies to protect health and the human environment through cleanups at Federal Facilities, including the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980, which was amended by the Superfund Amendments and Reauthorization Act (SARA) in 1986; the Defense Authorization Amendments and Base Realignment and Closure Acts (BRAC) of 1998 and the Defense Base Closure and Realignment Act of 1990; and the Resource Conservation and Recovery Act (RCRA), as amended by the Hazardous and Solid Waste Amendments of 1984 (HS WA) including Subtitle C (hazardous waste), Subtitle D (solid waste), Subtitle I (underground storage tanks), and Subtitle J (Medical Waste Tracking Act of 1988).14 days ago
- The U.S. Environmental Protection Agency (EPA) Office of Land and Emergency Management (OLEM) Center for Program Analysis (CPA) initiated the RE-Powering America’s Land Initiative to demonstrate the enormous potential that contaminated lands, landfills, and mine sites provide for developing renewable energy in the United States. EPA developed national level site screening criteria in partnership with the U.S. Department of Energy (DOE) National Renewable Energy Laboratory (NREL) for wind, solar, biomass, and geothermal facilities. While the screening criteria demonstrate the potential to reuse contaminated land for renewable energy facilities, the criteria and data are neither designed to identify the best sites for developing renewable energy nor all-inclusive. Therefore, more detailed, site-specific analysis is necessary to identify or prioritize the best sites for developing renewable energy facilities based on the technical and economic potential. Please note that these sites were only pre-screened for renewable energy potential. The sites were not evaluated for land use constraints or current on the ground conditions. Additional research and site-specific analysis are needed to verify viability for renewable energy potential at a given site.14 days ago

- This is a provisional dataset that contains point locations for the subset of Community Action for a Renewed Environment (CARE) grants given out by the US EPA. CARE is a competitive grant program that offers an innovative way for a community to organize and take action to reduce toxic pollution in its local environment. There are many limitations to the data so it is advised that these metadata be read carefully before use. Although the records for these grant locations are drawn directly from the official EPA grants repository (IGMS Integrated Grants Management System), it is important to know that the IGMS was designed for purposes that did not include accurately portraying the grants place of performance on a map. Instead, the IGMS grant recipients mailing address is the primary source for grant locations. Particularly for statewide grants that are administered via State and Regional headquarters, the grant location data should not be interpreted as the grants place of performance. In 2012, a policy was established to start to collect the place of performance as a pilot for newly awarded grants that were deemed community-based in nature and for these the grant location depicted in this database will be a more reliable indicator of the actual place of performance. As for the locational accuracy of these points, there is no programmatic certification process, however, they are being entered by the Grant Project Officers who are most familiar with the details of the grants, apart from the grantees themselves. Limitations notwithstanding, this is a first-of-breed attempt to map all of the Agencys grants, using the best internal geocoding algorithms available, and is a useful tool for getting to an understanding of the distribution of USEPA grant-giving. The CARE Grants layer contains Places of Performance for single locations or areas where CARE grants are applied.04 days ago

- These data provide mapping, display, and analysis capabilities for the TRI National Analysis data at the following geographic levels: state, county, large aquatic ecosystem, metro/micropolitan statistical area, and facility. See the links below for data from specific reporting years. The TRI National Analysis is EPA's annual interpretation and summary of the most recent TRI data. It highlights how toxic chemical wastes were managed, where toxic chemicals were released and in what quantities, and how the TRI data compare to data from previous years. This dataset reports US, state, county, large aquatic ecosystem, metro/micropolitan statistical area, and facility level statistics of TRI releases, including information on: number of TRI facilities in the geographic area and their releases (total releases, as well as releases to water, air, and land); population information, including populations living within 1 mile of TRI facilities (total population, percent minority, and in percent under the poverty line); and Risk Screening Environmental Indicators (RSEI) model related pounds, toxicity-weighted pounds, and RSEI score. The source of administrative boundary data is the 2013 cartographic boundary shapefiles. Location of facilities is provided by EPA's Facility Registry Service (FRS). Large Aquatic Ecosystems boundaries were derived from the hydrologic unit boundaries and codes for the United States, Puerto Rico, and the U.S. Virgin Islands. It was revised for inclusion in the National Atlas of the United States of America (November 2002), and updated to match the streams file created by the USGS National Mapping Division (NMD) for the National Atlas of the United States of America.04 days ago

- The EPA Recovery Mapper is an Internet interactive mapping application that allows users to discover information about every American Recovery and Reinvestment Act (ARRA) award that EPA has funded for six programs. By integrating data reported by the recipients of Recovery Act funding and data created by EPA, this application delivers a level of transparency and public accessibility to users interested in EPA's use of Recovery Act monies. The application is relatively easy to use and builds on the same mapping model as Google, Bing, MapQuest and other commonly used mapping interfaces. EPA Recovery Mapper tracks each award made by each program and gives basic Quick Facts information for each award including award name, location, award date, dollar amounts and more. Data Summaries for each EPA program or for each state are provided displaying dollars for Total Awarded, Total Received (Paid), and Total Jobs This Quarter by Recovery for the latest quarter of data released by Recovery.gov. The data are reported to the government and EPA four times a year by the award recipients. The latest quarterly report will always be displayed in the EPA Recovery Mapper. In addition, the application provides many details about each award. Users will learn more about how to access and interpret these data later in this document. Data shown in the EPA Recovery Mapper are derived from information reported back to FederalReporting.gov from the recipients of Recovery Act funding. EPA reviews the recipient reported data and works with the recipients to correct the data when errors are found. Please note that the dollar amounts displayed at Recovery.gov may differ somewhat from the amounts in this application because EPA Recovery Mapper includes awards that EPA has funded for Superfund sites cleanups that were awarded by the US Army Corps of Engineers. Also, EPA Recovery Mapper also does not display awards for management and oversight and awards made to EPA's Inspector General which account for less than 1.4% of the Recovery Act funding that EPA has received.14 days ago

- This map service displays Level III and Level IV Ecoregions of the United States and was created from ecoregion data obtained from the U.S. Environmental Protection Agency Office of Research and Development's Western Ecology Division. The original ecoregion data was projected from Albers to Web Mercator for this map service. To download shapefiles of ecoregion data (in Albers), please go to: https://dmap-prod-oms-edc.s3.us-east-1.amazonaws.com/index.html#ORD/Ecoregions/. IMPORTANT NOTE ABOUT LEVEL IV POLYGON LEGEND DISPLAY IN ARCMAP: Due to the limitations of Graphical Device Interface (GDI) resources per application on Windows, ArcMap does not display the legend in the Table of Contents for the ArcGIS Server service layer if the legend has more than 100 items. As of December 2011, there are 968 unique legend items in the Level IV Ecoregion Polygon legend. Follow this link (http://support.esri.com/en/knowledgebase/techarticles/detail/33741) for instructions about how to increase the maximum number of ArcGIS Server service layer legend items allowed for display in ArcMap. Note the instructions at this link provide a slightly incorrect path to "Maximum Legend Count". The correct path is HKEY_CURRENT_USER > Software > ESRI > ArcMap > Server > MapServerLayer > Maximum Legend Count. When editing the "Maximum Legend Count", update the field, "Value data" to 1000. To download a PDF version of the Level IV ecoregion map and legend, go to https://dmap-prod-oms-edc.s3.us-east-1.amazonaws.com/ORD/Ecoregions/us/Eco_Level_IV_US_pg.pdf. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another. A Roman numeral hierarchical scheme has been adopted for different levels for ecological regions. Level I is the coarsest level, dividing North America into 15 ecological regions. Level II divides the continent into 52 regions (Commission for Environmental Cooperation Working Group, 1997). At Level III, the continental United States contains 104 regions whereas the conterminous United States has 85 (U.S. Environmental Protection Agency, 2005). Level IV ecoregions (n = 968) are further subdivisions of Level III ecoregions. Methods used to define the ecoregions are explained in Omernik (1995, 2004), Omernik and others (2000), and Gallant and others (1989).

Included in this package are a file geodatabase and full FGDC metadata records for each layer. These layers identify areas in the U.S. where air pollution levels have not met the National Ambient Air Quality Standards (NAAQS) for criteria air pollutants and have been designated "nonattainment” areas (NAA)". The data are updated weekly from an OAQPS internal database. However, that does not necessarily mean the data have changed. The EPA Office of Air Quality Planning and Standards (OAQPS) has set National Ambient Air Quality Standards for six principal pollutants, which are called "criteria" pollutants. Under provisions of the Clean Air Act, which is intended to improve the quality of the air we breathe, EPA is required to set National Ambient Air Quality Standards for six common air pollutants. These commonly found air pollutants (also known as "criteria pollutants") are found all over the United States. They are particle pollution (often referred to as particulate matter), ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. For each criteria pollutant, there are specific procedures used for measuring ambient concentrations and for calculating long-term (quarterly or annual) and/or short-term (24-hour) exposure levels. The methods and allowable concentrations vary from one pollutant to another, and within NAAQS revisions for each pollutant. These pollutants can harm your health and the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats. EPA calls these pollutants "criteria" air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels. The set of limits based on human health is called primary standards. Another set of limits intended to prevent environmental and property damage is called secondary standards. A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. In some cases, a designated nonattainment area can include portions of 2, 3, or 4 states rather than falling entirely within a single state. Multi-state areas have had different state portions handled through up to 3 separate EPA regional offices. The actions of EPA and the state governments for separate portions of such areas are not always simultaneous. While some areas have had coordinated action from all related states on the same day, other areas (so-called "split areas") have had delays of several months, ranging up to more than 2 years, between different states. EPA must designate areas as meeting (attainment) or not meeting (nonattainment) the standard. A designation is the term EPA uses to describe the air quality in a given area for any of the six common air pollutants (criteria pollutants). After EPA establishes or revises a primary and/or secondary National Ambient Air Quality Standard (NAAQS), the Clean Air Act requires EPA to designate areas as "attainment" (meeting), "nonattainment" (not meeting), or "unclassifiable" (insufficient data) after monitoring data is collected by state, local and tribal governments. Once nonattainment designations take effect, the state and local governments have three years to develop implementation plans outlining how areas will attain and maintain the standards by reducing air pollutant emissions. For further information please refer to: https://www3.epa.gov/airquality/greenbook/index.html. Questions concerning the status of nonattainment areas, their classification and EPA policy should be directed to the appropriate Regional Offices (https://www.epa.gov/approved-sips/regional-sip-coordinators). EPA Headquarters should be contacted only when the Regional Office is unable to answer a question.14 days ago

- This US EPA Office of Air and Radiation, Office of Air Quality Planning and Standards, Air Quality Assessment Division, Air Quality Analysis Group (OAR, OAQPS, AQAD, AQAG) web service contains the following layers created from the 2008, 2011 and 2014 National Emissions Inventory (NEI): Carbon Monoxide (CO), Lead, Ammonia (NH3), Nitrogen Oxides (NOx), Particulate Matter 10 (PM10), Particulate Matter 2.5 (PM2.5), Sulfur Dioxide (SO2), Volatile Organic Compounds (VOC). Each of these layers conatin county level emissions for 2008, 2011, and 2014. Layers are drawn at all scales. The National Emission Inventory (NEI) is a comprehensive and detailed estimate of air emissions of criteria pollutants, criteria precursors, and hazardous air pollutants from air emissions sources. The NEI is released every three years based primarily upon data provided by State, Local, and Tribal air agencies for sources in their jurisdictions and supplemented by data developed by the US EPA. The NEI is built using the Emissions Inventory System (EIS) first to collect the data from State, Local, and Tribal air agencies and then to blend that data with other data sources. NEI point sources include emissions estimates for larger sources that are located at a fixed, stationary location. Point sources in the NEI include large industrial facilities and electric power plants, airports, and smaller industrial, non-industrial and commercial facilities. A small number of portable sources such as some asphalt or rock crushing operations are also included. Some states voluntarily also provide facilities such as dry cleaners, gas stations, and livestock facilities, which are otherwise included in the NEI as nonpoint sources. The emissions potential of each facility determines whether that facility should be reported as a point source, according to emissions thresholds set in the Air Emissions Reporting Rule (AERR). NEI Point Sources are all included in the EIS Point Data Category. NEI nonpoint sources include emissions estimates for sources which individually are too small in magnitude to report as point sources. These emissions sources are included in the NEI as a county total or tribal total (for participating tribes). Examples include residential heating, commercial combustion, asphalt paving, and commercial and consumer solvent use. NEI nonpoint sources are all included in the EIS Nonpoint Data Category.14 days ago

For each criteria pollutant, there are specific procedures used for measuring ambient concentrations and for calculating long-term (quarterly or annual) and/or short-term (24-hour) exposure levels. The methods and allowable concentrations vary from one pollutant to another, and within NAAQS revisions for each pollutant. These pollutants can harm your health and the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats. EPA calls these pollutants "criteria" air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels. The set of limits based on human health is called primary standards. Another set of limits intended to prevent environmental and property damage is called secondary standards. A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. In some cases, a designated nonattainment area can include portions of 2, 3, or 4 states rather than falling entirely within a single state. Multi-state areas have had different state portions handled through up to 3 separate EPA regional offices. The actions of EPA and the state governments for separate portions of such areas are not always simultaneous. While some areas have had coordinated action from all related states on the same day, other areas (so-called "split areas") have had delays of several months, ranging up to more than 2 years, between different states. EPA must designate areas as meeting (attainment) or not meeting (nonattainment) the standard. A designation is the term EPA uses to describe the air quality in a given area for any of the six common air pollutants (criteria pollutants). After EPA establishes or revises a primary and/or secondary National Ambient Air Quality Standard (NAAQS), the Clean Air Act requires EPA to designate areas as "attainment" (meeting), "nonattainment" (not meeting), or "unclassifiable" (insufficient data) after monitoring data is collected by state, local and tribal governments. Once nonattainment designations take effect, the state and local governments have three years to develop implementation plans outlining how areas will attain and maintain the standards by reducing air pollutant emissions. For further information please refer to: https://www.epa.gov/oar/oaqps/greenbk/index.html. Questions concerning the status of nonattainment areas, their classification and EPA policy should be directed to the appropriate Regional Offices (https://www.epa.gov/oar/oaqps/greenbk/regcntct.html).

For each criteria pollutant, there are specific procedures used for measuring ambient concentrations and for calculating long-term (quarterly or annual) and/or short-term (24-hour) exposure levels. The methods and allowable concentrations vary from one pollutant to another, and within NAAQS revisions for each pollutant. These pollutants can harm your health and the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats. EPA calls these pollutants "criteria" air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels. The set of limits based on human health is called primary standards. Another set of limits intended to prevent environmental and property damage is called secondary standards. A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. In some cases, a designated nonattainment area can include portions of 2, 3, or 4 states rather than falling entirely within a single state. Multi-state areas have had different state portions handled through up to 3 separate EPA regional offices. The actions of EPA and the state governments for separate portions of such areas are not always simultaneous. While some areas have had coordinated action from all related states on the same day, other areas (so-called "split areas") have had delays of several months, ranging up to more than 2 years, between different states. EPA must designate areas as meeting (attainment) or not meeting (nonattainment) the standard. A designation is the term EPA uses to describe the air quality in a given area for any of the six common air pollutants (criteria pollutants). After EPA establishes or revises a primary and/or secondary National Ambient Air Quality Standard (NAAQS), the Clean Air Act requires EPA to designate areas as "attainment" (meeting), "nonattainment" (not meeting), or "unclassifiable" (insufficient data) after monitoring data is collected by state, local and tribal governments. Once nonattainment designations take effect, the state and local governments have three years to develop implementation plans outlining how areas will attain and maintain the standards by reducing air pollutant emissions. For further information please refer to: https://www.epa.gov/approved-sips/regional-sip-coordinators. Questions concerning the status of nonattainment areas, their classification and EPA policy should be directed to the appropriate Regional Offices (https://www.epa.gov/approved-sips/regional-sip-coordinators). EPA Headquarters should be contacted only when the Regional Office is unable to answer a question.14 days ago

- This map service contains participants in EPA's Air Quality Flags Program. The map service also includes the current day's AQI forecast for each participant in the program. The Air Quality Flag Program alerts organizations to the local air quality forecast and helps them to take actions to protect people’s health, including those with asthma. Here's how it works: each day your organization raises a flag that corresponds to how clean or polluted the air is. The color of the flag matches EPA's Air Quality Index (AQI): green, yellow, orange, red, and purple. On unhealthy days, your organization can use this information to adjust physical activities to help reduce exposure to air pollution, while still keeping people active.14 days ago
- The Walkability Index dataset characterizes every Census 2019 block group in the U.S. based on its relative walkability. Walkability depends upon characteristics of the built environment that influence the likelihood of walking being used as a mode of travel. The Walkability Index is based on the EPA's previous data product, the Smart Location Database (SLD). Block group data from the SLD was the only input into the Walkability Index, and consisted of four variables from the SLD weighted in a formula to create the new Walkability Index. This dataset shares the SLD's block group boundary definitions from Census 2019. The methodology describing the process of creating the Walkability Index can be found in the documents located at https://edg.epa.gov/EPADataCommons/public/OA/WalkabilityIndex.zip.

This map presents information on the following criteria included in the 2020 National Green Building Standard: • Section 405.6(7) - Points for sites located in census block groups with above-average transit access to employment. (See variable D5b in Smart Location Database Technical Documentation and User Guide (2014) for background) • Section 405.6(8) - Points for sites located in census block groups with above-average access to employment within a 45-minute drive (See variable D5a in Smart Location Database Technical Documentation and User Guide (2014) for background on methods) • Section 501.2(4) - Points for lots located in census block groups with above-average neighborhood walkability (See National Walkability Index for background on methods) • Section 11.501.2(3) - Points for lots located in census block groups with above-average neighborhood walkability (See National Walkability Index for background on methods) Using data available through EPA’s Smart Location Database and National Walkability Index, relative walkability and accessibility to jobs via transit or within a 45-minute drive for census block groups were calculated and ranked into quartile groups. The regional comparison was made by considering the score of each individual census block group as a ratio of the average score of the county in which it is located. Those block groups with scores in the highest two quartiles nationally are eligible for NGBS points per the Sections noted above.

- Jobs Within a 30-minute Transit and Walking Commute04 days ago
- A collection of performance indicators for consistently comparing neighborhoods (census block groups) across the US in regards to their accessibility to jobs or workers via public transit service. Accessibility was modeled by calculating total travel time between block group centroids inclusive of walking to/from transit stops, wait times, and transfers. Block groups that can be accessed in 30 minutes or less from the origin block group are considered accessible. Indicators reflect public transit service in December 2012 and employment/worker counts in 2010. Coverage is limited to census block groups within metropolitan regions served by transit agencies who share their service data in a standardized format called GTFS. All variable names refer to variables in EPA's Smart Location Database. For instance EmpTot10_sum summarizes total employment (EmpTot10) in block groups that are reachable within a 30-minute transit and walking commute.

- The Washington DC EnviroAtlas Meter-scale Urban Land Cover (MULC) dataset comprises an area of 5423.43 km2 encompassing the entire area of Washington DC, and portions of the state of Maryland and state of Virginia. These MULC data and maps were derived from 1-m pixel, four-band (red, green, blue, and infrared light) leaf-on aerial photography acquired from the United States Department of Agriculture (USDA) National Agriculture Imagery Program (NAIP) as well as ancillary data (e.g., Lidar, National Wetlands Inventory [NWI], cropland, land parcels, power lines, building footprints). Eight land cover classes were mapped: Water, Impervious Surfaces, Soil/Barren, Trees/Forest, Grass/Herbaceous, Agriculture, Woody Wetlands and Emergent Wetlands. Wetlands were delineated using the state wide wetlands data from National Wetlands Inventory (NWI) layer updated on October 15, 2018 (https://www.fws.gov/wetlands/Data/State-Downloads.html ). An analysis of 600 completely random and 111 stratified random photo-interpreted land cover reference points yielded a simple overall user's accuracy (MAX) of 85.4% and an overall fuzzy user's accuracy (RIGHT) of 91.5% within the census block group boundary (see confusion matrices below). These data were developed as part of the Chesapeake Bay High-Resolution Land Cover Project, a cooperative agreement between the Chesapeake Conservancy and the National Park Service, funded through an interagency agreement with the Environmental Protection Agency (EPA). The Chesapeake Conservancy, under the direction of Margaret Markham, created the initial statewide 1-meter land cover data. EPA added agriculture and wetlands taken from ancillary data sources.

- This EnviroAtlas dataset was produced by a joint effort of New Mexico State University, US Environmental Protection Agency (US EPA,) and the U.S. Geological Survey (USGS) to support research and online mapping activities related to EnviroAtlas. Ecosystem services, i.e., services provided to humans from ecological systems have become a key issue of this century in resource management, conservation planning, and environmental decision analysis. Mapping and quantifying ecosystem services have become strategic national interests for integrating ecology with economics to help understand the effects of human policies and actions and their subsequent impacts on both ecosystem function and human well-being. Some aspects of biodiversity are valued by humans in varied ways, and thus are important to include in any assessment that seeks to identify and quantify the benefits of ecosystems to humans. Some biodiversity metrics clearly reflect ecosystem services (e.g., abundance and diversity of harvestable species), whereas others may reflect indirect and difficult to quantify relationships to services (e.g., relevance of species diversity to ecosystem resilience, cultural and aesthetic values). Wildlife habitat has been modeled at broad spatial scales and can be used to map a number of biodiversity metrics. We map 15 biodiversity metrics reflecting ecosystem services or other aspects of biodiversity for all vertebrate species except fish. Metrics include species richness for all vertebrates, specific taxon groups, harvestable species (i.e., upland game, waterfowl, furbearers, small game, and big game), threatened and endangered species, and state-designated species of greatest conservation need, and also a metric for ecosystem (i.e., land cover) diversity.

- This EnviroAtlas national dataset shows the average annual sediment yield in metric tons per hectare*10,000 to the nearest waterbody by each pixel for the conterminous United States for 2011 under a scenario in which natural vegetation has been removed. This raster is part of a collection of eight rasters showing soil loss, sediment delivery ratio, and sediment yield to streams and waterbodies under two land cover scenarios, and the difference between both scenarios for soil loss and sediment yield. The two scenarios are the existing vegetation scenario based on the 2011 National Land Cover Database (NLCD), and a scenario in which natural land cover was replaced with barren land. Average annual soil loss due to sheet and rill erosion was calculated using the Revised Universal Soil Loss Equation (RUSLE) equation for both scenarios. A Sediment Delivery Ratio (SDR) was then applied to both scenarios. The SDR was multiplied by the average annual soil loss to estimate net sediment yield to downstream waterways under both scenarios. These datasets can be used together to quantify the soil retention services of natural vegetation. The datasets used as inputs include the 2011 NLCD, 1971-2000 Rainfall-runoff erosivity factor from PRISM (Parameter-elevation Regressions on Independent Slopes Model), the U.S. Geological Survey's 30-meter digital elevation model (DEM), Soil Survey Geographic Database (SSURGO), and State Soil Geographic Database (STATSGO2) data, MODIS (Moderate Resolution Imaging Spectroradiometer) Normalized Difference Vegetation Index (NDVI), and the US Department of Agriculture (USDA)'s crop management zones (CMZs).

- This EnviroAtlas dataset contains information about stressors in the upstream watersheds of stream confluences. Stream confluences are important components of fluvial networks. Hydraulic forces meeting at stream confluences often produce changes in streambed morphology and sediment distribution, and these changes often increase habitat heterogeneity relative to upstream and downstream locations. Increases in habitat heterogeneity at stream confluences have led some to identify them as biological hotspots. Despite their potential ecological importance, there are relatively few empirical studies documenting ecological patterns across the upstream-confluence-downstream gradient. To facilitate more studies of the ecological value and role of stream confluences in fluvial networks, we have produced a database of stream confluences and their associated watershed attributes for the conterminous United States. The database includes 1,085,629 stream confluences and 383 attributes for each confluence that are organized into 15 database tables for both tributary and mainstem upstream catchments ("local" watersheds) and watersheds. Themes represented by the database tables include hydrology (e.g., stream order), land cover and land cover change, geology (e.g., calcium content of underlying lithosphere), physical condition (e.g., precipitation), measures of ecological integrity, and stressors (e.g., impaired streams). We use measures of ecological integrity (Thornbrugh et al. 2018) from the StreamCat database (Hill et al. 2016) to classify stream confluences using disjoint clustering and validate the cluster results using decision tree analysis.

- The annual average direct normal solar resources by 12-Digit Hydrologic Unit (HUC) was estimated from maps produced by the National Renewable Energy Laboratory for the U.S. Department of Energy (February 2009). The original data was from 10km, satellite modeled dataset (SUNY/NREL, 2007) representing data from 1998-2005. The 10km data was converted to 30m grid cells, and then zonal statistics were estimated for a final value of average kWh/m2/day for each 12-digit HUC. For more information about the original dataset please refer to the National Renewable Energy Laboratory (NREL) website at www.nrel.gov/gis/data_solar.html.

- This EnviroAtlas national dataset shows the average sediment delivery ratio (SDR) - the percentage of soil eroding from a pixel that is transported to a downstream water body - per pixel *1.0e4 for the conterminous United States for 2011 under a scenario in which natural vegetation has been removed. This raster is part of a collection of eight rasters showing soil loss, sediment delivery ratio, and sediment yield to streams and waterbodies under two land cover scenarios, and the difference between both scenarios for soil loss and sediment yield. The two scenarios are the existing vegetation scenario based on the 2011 National Land Cover Database (NLCD), and a scenario in which natural land cover was replaced with barren land. Average annual soil loss due to sheet and rill erosion was calculated using the Revised Universal Soil Loss Equation (RUSLE) equation for both scenarios. A Sediment Delivery Ratio (SDR) was then applied to both scenarios. The SDR was multiplied by the average annual soil loss to estimate net sediment yield to downstream waterways under both scenarios. These datasets can be used together to quantify the soil retention services of natural vegetation. The datasets used as inputs include the 2011 NLCD, 1971-2000 Rainfall-runoff erosivity factor from PRISM (Parameter-elevation Regressions on Independent Slopes Model), the U.S. Geological Survey's 30-meter digital elevation model (DEM), Soil Survey Geographic Database (SSURGO), and State Soil Geographic Database (STATSGO2) data, MODIS (Moderate Resolution Imaging Spectroradiometer) Normalized Difference Vegetation Index (NDVI), and the US Department of Agriculture (USDA)'s crop management zones (CMZs).

- This dataset is a summary of crop acres without nearby pollinator habitat. Pollination habitat here is defined as trees (fruit, nut, deciduous, and evergreen). Crops are only those that either benefit from or require pollinators in order to produce or improve crop production. The maximum distance a tree habitat could be from the crop pixel was 2.8 km. If the crop had no tree habitat within this distance (euclidean) then it was selected as needing habitat. The total areas of crops without nearby pollinator habitat was then summed by 12 digit HUCS. This metric is a measure of demand for pollinators in order to improve or produce crop yields.

- This EnviroAtlas dataset contains information about physical characteristics, such as temperature, elevation, and precipitation, in the upstream watersheds of stream confluences. Stream confluences are important components of fluvial networks. Hydraulic forces meeting at stream confluences often produce changes in streambed morphology and sediment distribution, and these changes often increase habitat heterogeneity relative to upstream and downstream locations. Increases in habitat heterogeneity at stream confluences have led some to identify them as biological hotspots. Despite their potential ecological importance, there are relatively few empirical studies documenting ecological patterns across the upstream-confluence-downstream gradient. To facilitate more studies of the ecological value and role of stream confluences in fluvial networks, we have produced a database of stream confluences and their associated watershed attributes for the conterminous United States. The database includes 1,085,629 stream confluences and 383 attributes for each confluence that are organized into 15 database tables for both tributary and mainstem upstream catchments ("local" watersheds) and watersheds. Themes represented by the database tables include hydrology (e.g., stream order), land cover and land cover change, geology (e.g., calcium content of underlying lithosphere), physical condition (e.g., precipitation), measures of ecological integrity, and stressors (e.g., impaired streams). We use measures of ecological integrity (Thornbrugh et al. 2018) from the StreamCat database (Hill et al. 2016) to classify stream confluences using disjoint clustering and validate the cluster results using decision tree analysis.

- This EnviroAtlas national map displays the application rate of phosphorus (P) as manure on croplands in the conterminous United States (excluding Hawaii and Alaska) for the year 2012 by 12-digit HUC. These data are based on county-level data on P as recoverable manure from concentrated animal feeding operations (CAFOs) from the International Plant Nutrition Institute (IPNI) and cropland area from the USGS's U.S. conterminous wall-to-wall anthropogenic land use trends (NWALT) 2012 land cover data. These are thus not actual application rates but rather estimated rates based on the production of recoverable manure and the amount of agricultural lands close by.

- This EnviroAtlas dataset contains data on the mean livestock manure application to cultivated crop and hay/pasture lands by 12-digit Hydrologic Unit (HUC) in 2006. Livestock manure inputs to cultivated crop and hay/pasture lands were estimated using county-level estimates of recoverable animal manure from confined feeding operations compiled for 2007. Recoverable manure is defined as manure that is collected, stored, and available for land application from confined feeding operations. County-scale data on livestock populations -- needed to calculate manure inputs -- were only available for the year 2007 from the USDA Census of Agriculture (http://www.agcensus.usda.gov/index.php). We acquired county-level data describing total farm-level inputs (kg N/yr) of recoverable manure to individual counties in 2007 from the International Plant Nutrition Institute (IPNI) Nutrient Geographic Information System (NuGIS; http://www.ipni.net/nugis). These data were converted to per area rates (kg N/ha/yr) of manure N inputs by dividing the total N input by the land area (ha) of combined cultivated crop and hay/pasture (agricultural) lands within a county as determined from county-level summarization of the 2006 NLCD. We distributed county-specific, per area N inputs rates to cultivated crop and hay/pasture lands (30 x 30 m pixels) within the corresponding county. Manure data described here represent an average input to a typical agricultural land type within a county, i.e., they are not specific to individual crop types.

- This EnviroAtlas dataset contains changes in land cover proportions between 2001 and 2011 for the upstream watersheds of stream confluences. Stream confluences are important components of fluvial networks. Hydraulic forces meeting at stream confluences often produce changes in streambed morphology and sediment distribution, and these changes often increase habitat heterogeneity relative to upstream and downstream locations. Increases in habitat heterogeneity at stream confluences have led some to identify them as biological hotspots. Despite their potential ecological importance, there are relatively few empirical studies documenting ecological patterns across the upstream-confluence-downstream gradient. To facilitate more studies of the ecological value and role of stream confluences in fluvial networks, we have produced a database of stream confluences and their associated watershed attributes for the conterminous United States. The database includes 1,085,629 stream confluences and 383 attributes for each confluence that are organized into 15 database tables for both tributary and mainstem upstream catchments ("local" watersheds) and watersheds. Themes represented by the database tables include hydrology (e.g., stream order), land cover and land cover change, geology (e.g., calcium content of underlying lithosphere), physical condition (e.g., precipitation), measures of ecological integrity, and stressors (e.g., impaired streams). We use measures of ecological integrity (Thornbrugh et al. 2018) from the StreamCat database (Hill et al. 2016) to classify stream confluences using disjoint clustering and validate the cluster results using decision tree analysis.

- The Los Angeles County, CA Meter Urban Land Cover (MULC) dataset was generated from sub-meter image pixel resolution data created by the University of Vermont Spatial Analysis Laboratory (SAL) through the combined use of 2016 USDA National Agricultural Imagery Program (NAIP) four band (red, green, blue and near infrared) aerial imagery, 2016 LiDAR data and 2014 ortho-imagery. The sub-meter, thematic landcover data feature attributes were recoded and spatially resampled to a 1-meter spatial scale by EPA for MULC data product integration. The mapped area is confined to the boundaries of US Census Bureau's 2010 Urban Statistical Area for Los Angeles County, with an added 1km coastal water buffer area extension. The following eight land cover classes were mapped: Water, Impervious, Soil or Barren, Trees or Forest, Grass or Herbaceous, Woody Wetlands and Emergent Wetlands. Integrated wetland features were derived using ancillary National Wetlands Inventory (NWI) polygon data (version 2), downloaded from the Unites States Fish and Wildlife Service (USFWS) Wetland Mapper web mapping service (https://www.fws.gov/wetlands/data/mapper.html). Metadata for the NWI wetlands data layer can be found at http://www.fws.gov/wetlands/Data/Metadata.html. An accuracy assessment of the classified product, using 887 completely random and 40 stratified random photo-interpreted land cover reference sample points yielded an overall user's accuracy (MAX) of 61.1 percent and a fuzzy user's accuracy (RIGHT) of 89.2 percent.

- This EnviroAtlas dataset contains information about hydrologic attributes of the upstream catchments and watersheds of stream confluences. Stream confluences are important components of fluvial networks. Hydraulic forces meeting at stream confluences often produce changes in streambed morphology and sediment distribution, and these changes often increase habitat heterogeneity relative to upstream and downstream locations. Increases in habitat heterogeneity at stream confluences have led some to identify them as biological hotspots. Despite their potential ecological importance, there are relatively few empirical studies documenting ecological patterns across the upstream-confluence-downstream gradient. To facilitate more studies of the ecological value and role of stream confluences in fluvial networks, we have produced a database of stream confluences and their associated watershed attributes for the conterminous United States. The database includes 1,085,629 stream confluences and 383 attributes for each confluence that are organized into 15 database tables for both tributary and mainstem upstream catchments ("local" watersheds) and watersheds. Themes represented by the database tables include hydrology (e.g., stream order), land cover and land cover change, geology (e.g., calcium content of underlying lithosphere), physical condition (e.g., precipitation), measures of ecological integrity, and stressors (e.g., impaired streams). We use measures of ecological integrity (Thornbrugh et al. 2018) from the StreamCat database (Hill et al. 2016) to classify stream confluences using disjoint clustering and validate the cluster results using decision tree analysis. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas.

- This EnviroAtlas dataset contains data on the mean synthetic nitrogen (N) fertilizer application to cultivated crop and hay/pasture lands per 12-digit Hydrologic Unit (HUC) in 2006. Synthetic N fertilizer inputs in 2006 were estimated using county-level estimates of farm N fertilizer inputs. We acquired county-level data describing total farm-level inputs (kg N/yr) of synthetic N fertilizer to individual counties in 2006 from the United States Geological Survey (USGS) (http://pubs.usgs.gov/sir/2012/5207/). These data were converted to per area rates (kg N/ha/yr) of synthetic N fertilizer application by dividing the total N input by the land area (ha) of combined cultivated crop and hay/pasture lands within a county as determined from county-level (http://cta.ornl.gov/transnet/Boundaries.html) summarization of the 2006 National Land Cover Database (NLCD; http://www.mrlc.gov/nlcd06_data.php). We distributed county-specific, annual per area N inputs rates (kg N/ha/yr) to cultivated crop and hay/pasture lands (30 x 30 m pixels) within the corresponding county using the raster calculator tool in ArcMap 10.0 (ESRI, Inc., Redlands, CA). Fertilizer data described here represent an average input to a typical agricultural land type within a county, i.e., they are not specific to individual crop types.

- Understanding the relationship between flood inundation and floodplains is critical for ecosystem and community health and well-being, as well as targeting floodplain and riparian restoration. Many communities in the United States, particularly those in rural areas, lack inundation maps due to the high cost of flood modeling. Only 60% of the conterminous United States has Flood Insurance Rate Maps (FIRMs) through the U.S. Federal Emergency Management Agency (FEMA). This EnviroAtlas dataset provides an estimate of the 100-year floodplain for the conterminous United States at 30-meter resolution to fill the gaps in the FIRM. The model hit rate for the CONUS was 0.79 compared to the FIRM, indicating that the model captured 79% of the 100-year floodplain identified by FEMA. This product provides complete coverage for the CONUS by identifying floodplains in areas without FIRMs, while also identifying floodplains in tributaries sometimes excluded by FEMA.

- This EnviroAtlas dataset contains indices of ecological integrity in the upstream catchments and watersheds of stream confluences. Stream confluences are important components of fluvial networks. Hydraulic forces meeting at stream confluences often produce changes in streambed morphology and sediment distribution, and these changes often increase habitat heterogeneity relative to upstream and downstream locations. Increases in habitat heterogeneity at stream confluences have led some to identify them as biological hotspots. Despite their potential ecological importance, there are relatively few empirical studies documenting ecological patterns across the upstream-confluence-downstream gradient. To facilitate more studies of the ecological value and role of stream confluences in fluvial networks, we have produced a database of stream confluences and their associated watershed attributes for the conterminous United States. The database includes 1,085,629 stream confluences and 383 attributes for each confluence that are organized into 15 database tables for both tributary and mainstem upstream catchments ("local" watersheds) and watersheds. Themes represented by the database tables include hydrology (e.g., stream order), land cover and land cover change, geology (e.g., calcium content of underlying lithosphere), physical condition (e.g., precipitation), measures of ecological integrity, and stressors (e.g., impaired streams). We use measures of ecological integrity (Thornbrugh et al. 2018) from the StreamCat database (Hill et al. 2016) to classify stream confluences using disjoint clustering and validate the cluster results using decision tree analysis.

- The EnviroAtlas Climate Scenarios were generated from NASA Earth Exchange (NEX) Downscaled Climate Projections (NEX-DCP30) ensemble averages (the average of over 30 available climate models) for each of the four representative concentration pathways (RCP) for the contiguous U.S. at 30 arc-second (approx. 800 m2) spatial resolution. In addition to the three climate variables provided by the NEX-DCP30 dataset (minimum monthly temperature, maximum monthly temperature, and precipitation) a corresponding estimate of potential evapotranspiration (PET) was developed to match the spatial and temporal scales of the input dataset. PET represents the cumulative amount of water returned to the atmosphere due to evaporation from Earth’s surface and plant transpiration under ideal circumstances (i.e., a vegetated surface shading the ground and unlimited water supply). PET was calculated using the Hamon PET equation (Hamon, 1961) and CBM model for daylength (Forsythe et al. 1995) for the 4 RCPs (2.6, 4.5, 6.0, 8.5) and organized by season (Winter, Spring, Summer, and Fall) and annually for the years 2006 – 2099. Additionally, PET was calculated for the ensemble average of all historic runs and organized similarly for the years 1950 – 2005.

- The Cleveland, OH EnviroAtlas Meter-scale Urban Land Cover (MULC) dataset comprises 2,737 km2 around the city of Cleveland and portions of surrounding counties. The area classified is based on the US Census Bureau's 2010 Urban Area for Cleveland, OH with a 1 km buffer added. This area includes the majority of Cuyahoga and Lake Counties, and portions of Ashtabula, Geauga, Medina, Lorain, Portage and Summit Counties. These MULC data and maps were derived from LiDAR and 1-m pixel, four-band (red, green, blue, and near-infrared) leaf-on aerial photography acquired from the United States Department of Agriculture (USDA) National Agriculture Imagery Program (NAIP) in 2011 and 2013. The NAIP imagery was collected on several dates: August 12, 2011, September 03, 2011 and August 24, 2013. The data was comprised of 85% 2011 NAIP and 15% 2013 NAIP imagery. LiDAR data collected between March 18, 2006 and May 07, 2006 covered the entire study area. Six land cover classes were mapped: Water, Impervious Surfaces, Soil/Barren, Trees/Forest, Grass/Herbaceous Non-Woody Vegetation, and Wetlands (Woody and Emergent). Wetlands were copied from the best available existing wetlands data, which was a National Wetlands Inventory (NWI) layer from 2006. An analysis of 500 completely random and 81 stratified random photo-interpreted land cover reference points yielded an overall user's accuracy of 86.2% (see confusion matrix below).

- This EnviroAtlas dataset contains data on the mean cultivated biological nitrogen fixation (C-BNF) in cultivated crop and hay/pasture lands per 12-digit Hydrologic Unit (HUC) in 2006. Nitrogen (N) inputs from the cultivation of legumes, which possess a symbiotic relationship with N-fixing bacteria, were calculated with a recently developed model relating county-level yields of various leguminous crops with BNF rates. We accessed county-level data on annual crop yields for soybeans (Glycine max L.), alfalfa (Medicago sativa L.), peanuts (Arachis hypogaea L.), various dry beans (Phaseolus, Cicer, and Lens spp.), and dry peas (Pisum spp.) for 2006 from the USDA Census of Agriculture (http://www.agcensus.usda.gov/index.php). We estimated the yield of the non-alfalfa leguminous component of hay as 32% of the yield of total non-alfalfa hay (http://www.agcensus.usda.gov/index.php). Annual rates of C-BNF by crop type were calculated using a model that relates yield to C-BNF. We assume yield data reflect differences in soil properties, water availability, temperature, and other local and regional factors that can influence root nodulation and rate of N fixation. We distributed county-specific, C-BNF rates to cultivated crop and hay/pasture lands delineated in the 2006 National Land Cover Database (30 x 30 m pixels) within the corresponding county. C-BNF data described here represent an average input to a typical agricultural land type within a county, i.e., they are not specific to individual crop types.

- This EnviroAtlas dataset contains data on the mean biological nitrogen fixation in natural/semi-natural ecosystems per 12-digit Hydrologic Unit (HUC) in 2006. Biological N fixation (BNF) in natural/semi-natural ecosystems was estimated using a correlation with actual evapotranspiration (AET). This correlation is based on a global meta-analysis of BNF in natural/semi-natural ecosystems (Cleveland et al. 1999). AET estimates for 2006 were calculated using a regression equation describing the correlation of AET with climate (average annual daily temperature, average annual minimum daily temperature, average annual maximum daily temperature, and annual precipitation) and land use/land cover variables in the conterminous US (Sanford and Selnick 2013). Data describing annual average minimum and maximum daily temperatures and total precipitation for 2006 were acquired from the PRISM climate dataset (http://prism.oregonstate.edu). Average annual climate data were then calculated for individual 12-digit USGS Hydrologic Unit Codes (HUC12s; https://water.usgs.gov/GIS/huc.html; 22 March 2011 release) using the Zonal Statistics tool in ArcMap 10.0. AET for individual HUC12s was estimated using equations described in Sanford and Selnick (2013). BNF in natural/semi-natural ecosystems within individual HUC12s was modeled with an equation describing the statistical relationship between BNF (kg N ha-1 yr-1) and actual evapotranspiration (AET; cm yr-1) and scaled to the proportion of non-developed and non-agricultural land in the HUC12. The first half of the equation represents the most conservative estimate in a meta-analysis of BNF in natural/semi-natural ecosystems (Cleveland et al. 1999), and was chosen over the central and high estimates because recent, top-down global mass balances that suggest that natural BNF rates are less than previous estimates based on scaled-up estimates from individual plots (Vitousek et al. 2013). The land use/land cover modifier is not included in the original Cleveland et al. (1999) analysis. We believe it is appropriate to include so as not to overestimate BNF in HUC12s with large proportions of urban or agricultural development. These data represent an average N input to individual HUC12s, i.e., they are not specific to an individual land use type within the HUC12.

- This dataset was produced by a joint effort of New Mexico State University (NMSU), the U.S. Environmental Protection Agency (EPA), and the U.S. Geological Survey (USGS) to support research and online mapping activities related to EnviroAtlas. Ecosystem services, i.e., services provided to humans from ecological systems, have become a key issue of this century in resource management, conservation planning, and environmental decision analysis. Mapping and quantifying ecosystem services have become strategic national interests for integrating ecology with economics to help understand the effects of human policies and actions and their subsequent impacts on both ecosystem function and human well-being. Some aspects of biodiversity are valued by humans in varied ways, and thus are important to include in any assessment that seeks to identify and quantify the benefits of ecosystems to humans. Some biodiversity metrics clearly reflect ecosystem services (e.g., abundance and diversity of harvestable species), whereas others may reflect indirect and difficult to quantify relationships to services (e.g., relevance of species diversity to ecosystem resilience, or cultural and aesthetic values). Wildlife habitat has been modeled at broad spatial scales and can be used to map a number of biodiversity metrics. We map 15 biodiversity metrics reflecting ecosystem services or other aspects of biodiversity for bird species.

Agricultural irrigation water use, as defined in this case, meets a variety of needs before, during, and after growing seasons (e.g., dust suppression, field preparation, chemical application, weed control, salt removal from root zones, frost protection, crop cooling, and harvesting). Estimates include self-supplied surface and groundwater, as well as supplies from irrigation-specific organizations (e.g., companies, districts, cooperatives, government).

- This EnviroAtlas dataset estimates the average agricultural buffer width, the percentage of agricultural lands with flow paths that would intersect natural land cover before reaching a stream, and the percentage of each subwatershed (12-digit HUC) that is unbuffered agricultural land. Subwatershed summaries are calculated for the contiguous United States. The map uses a combined land use/land cover map from the 2006 National Land Cover Database (NLCD) and the 2010 Cropland Data Layer (CDL). It combines agriculture, forests, grasslands and wetlands with stream networks and elevation datasets in flow path models to find agricultural flow paths that do or do not intersect buffers, and counts the agricultural flow paths through buffers adjacent to streams in order to determine average buffer widths on agricultural lands.

- The dataset used for the analysis in the publication, Characterizing Adaptive Capacity for the Future Heat-Related Cardiovascular Morbidity Burden in U.S. Metropolitan Areas (DOI: https://doi.org/10.1016/j.envint.2025.110022). Abstract Exposure to excess heat is linked to increased risks of cardiovascular diseases (CVD). As temperatures increase globally, it is crucial to examine the potential increase in excess heat-related CVD (xHEAT-CVD) burden to inform strategies for adaptation. This study aimed to identify the contextual factors associated with future xHEAT-CVD burden among older adults across eighty U.S. metropolitan statistical areas (MSAs). The MSA-specific xHEAT-CVD risk for adults ≥ 65 years was estimated using hospitalization and temperature data from 2000 to 2017, with excess heat defined as temperatures above the minimum hospitalization percentile (TMHP). Future xHEAT-CVD hospitalizations were estimated using temperature projections for 2025–2054, 2045–2074, and 2070–2099 under three climate scenarios. Area-level variables were used to identify demographic and economic status, health, environment, and infrastructure contexts and derive Urban Heat Health Risk (UHHR) scores using confirmatory factor analysis. The associations between adaptive capacity (the UHHR scores) and future xHEAT-CVD burden were examined. In 2070–2099 under the mildest scenario, 36 more days annually were projected to be ≥ TMHP, and xHEAT-CVD burden was projected to increase by at least 20.4-fold. Lower adaptive capacity was associated with greater increases in future xHEAT-CVD burden, over 9-fold increase per 1-unit increase in UHHR score (9.1, 95 % Confidence Intervals: 2.8–15.4). The historical xHEAT-CVD burden (2000–2017) was largely driven by the health context, whereas environment played a more important role in the future. Our findings suggest that drivers of the xHEAT-CVD burden may vary across time. Targeting the areas with the highest xHEAT-CVD burden at varying timeframes can help mitigate xHEAT-CVD burden more effectively.

- This research focused on developing and evaluating nitrogen-stable isotope condition assessment bioindicators and monitoring methods for low gradient coastal stream systems to assist states in assessing the condition of low-gradient coastal systems. Low-gradient coastal stream systems support important landscape level ecological functions by connecting uplands and marshes directly to large tidal rivers, estuaries, and coastal waterbodies. In this study we develop and evaluate innovative monitoring and assessment methods to support biological indicator development for waterbody types and taxa that lack nationally consistent and reliable approaches. Low-gradient tidal and non-tidal coastal stream systems are infrequently included in national and regional monitoring programs and may require different methods than freshwater streams (US EPA National River and Streams Assessment) or large tidal rivers (US EPA National Coastal Condition Assessment). Results from this study demonstrate that stable isotopes of nitrogen (δ15N) bioindicators from a variety of biotic trophic levels can be used as an efficient and effective rapid monitoring tool for assessing biotic condition in low gradient coastal systems. These stable isotope indicators also provide empirical field measurements for ground-truthing national indices which are derived from remotely sensed national landscape data layers. The δ15N biotic responses were consistently significant across all trophic levels and negatively correlated with landscape level stressor exposure conditions reflected in the national and regional scale indices. Verifying national multiscale indices with site-scale field measured bioindicators (δ15N) provides coastal managers, states, tribal, regional, and local watershed organizations confidence in using these national indices at local watershed and catchment scales for identifying and prioritizing protection for healthy coastal stream networks and watersheds, as well as targeting critical functional elements of watersheds for restoration efforts.

Fish were exposed for 21 d to five water concentrations of FC10-diol ranging from 0.68 to 68 µg/L, as well as 17β-estradiol (15 ng/L) as a positive control. The FC10-diol produced a suite of responses in both males and female fish that were indicative of a classical estrogen-receptor (ER) agonist, including significant effects on reproduction. Responses in males included changes in expression of four hepatic genes controlled by ER, induction of plasma vitellogenin (VTG), decreased expression of male secondary sexual characteristics, histopathological changes in the testis and kidney, and mortality in the highest FC10-diol treatment group. Effects in females from the high treatment group included altered ovarian expression of genes involved in steroid synthesis, decreased plasma steroids, elevated plasma VTG, and histological changes in the ovary and kidney.

- Spatially explicit nutrient budgets are critical for managing nutrients and improving water quality. Yet, these budgets are resource-intensive to develop at the scales and extents needed for achieving management goals. In this paper we introduce StreamCatNNI and LakeCatNNI, an integration of the United States Environmental Protection Agency's (USEPA) Next Generation National Nutrient Inventory (NNI) with the StreamCat database. The NNI provides 30-year annual time-series (1987-2017) of nitrogen (N) and phosphorus (P) budgets for US counties. The NNI's integration with StreamCat yields watershed and local catchment N and P budgets for ~2.64 million stream segments and 378,088 lakes. These budgets contain major anthropogenic and natural inputs, outputs, agricultural surplus, and legacy agricultural surplus for N and P. StreamCatNNI and LakeCatNNI data were calculated using 1) a tabular dasymetric apportionment process to downscale NNI nutrient data to local drainages, then 2) the StreamCat accumulation framework to derive watershed nutrient budgets. StreamCatNNI and LakeCatNNI data underwent a variety of spatial quality assurance evaluations, and workflow components are publicly available for replication. This repository contains LakeCatNNI data. A second repository is maintained for StreamCatNNI.164 days ago
- Background: Accelerated transcriptomic and/or epigenetic age have been proposed as biomarkers of disrupted systemic health and of increased sensitivity to environmental exposures. Previously, we observed epigenetic age acceleration as a biomarker of sensitivity to air pollution, especially for traffic-related air pollution (TRAP) in urban cohorts. Methods: Using 1024 participants from the CATHGEN cohort, we evaluated whether increased cardiovascular risk associated with TRAP was modified by transcriptomic aging. Residential proximity to major roadways was the measure of TRAP and peripheral arterial disease (PAD) and blood pressure were outcomes. Blood-based gene expression-based age acceleration (GEXAge AAD) and Horvath epigenetic age acceleration (DNAmAge AAD) were measures of age acceleration, and models were adjusted for chronological age, race, sex, smoking, socioeconomic status, body mass index, hyperlipidemia, and diabetes. Results: We observed significant interactions between TRAP and GEXAge AAD and DNAmAge AAD, but these interactions were weaker than in previous analyses including only urban communities. Constraining the cohort to those residing in more urban environments strengthened the interaction between GEXAge AAD and TRAP. Interactions indicated that increased transcriptomic or epigenetic age elevated associations between proximity to roadways and PAD; the strongest interactions were identified in individuals with both accelerated epigenetic and transcriptomic age. Exploratory sex-stratified analyses identified potentially stronger associations in males, but these results would require further validation in larger studies. Conclusion: Similar to epigenetic age, elevated transcriptomic age may be an indicator of increased TRAP sensitivity. Individuals with jointly elevated epigenetic and transcriptomic age may have greater environmental health risks than those with elevated transcriptomic age alone.

- Spatially explicit nutrient budgets are critical for managing nutrients and improving water quality. Yet, these budgets are resource-intensive to develop at the scales and extents needed for achieving management goals. In this paper we introduce StreamCatNNI and LakeCatNNI, an integration of the United States Environmental Protection Agency's (USEPA) Next Generation National Nutrient Inventory (NNI) with the StreamCat database. The NNI provides 30-year annual time-series (1987-2017) of nitrogen (N) and phosphorus (P) budgets for US counties. The NNI's integration with StreamCat yields watershed and local catchment N and P budgets for ~2.64 million stream segments and 378,088 lakes. These budgets contain major anthropogenic and natural inputs, outputs, agricultural surplus, and legacy agricultural surplus for N and P. StreamCatNNI and LakeCatNNI data were calculated using 1) a tabular dasymetric apportionment process to downscale NNI nutrient data to local drainages, then 2) the StreamCat accumulation framework to derive watershed nutrient budgets. StreamCatNNI and LakeCatNNI data underwent a variety of spatial quality assurance evaluations, and workflow components are publicly available for replication. This repository contains StreamCatNNI data. A second repository is maintained for LakeCatNNI.204 days ago

- Abstract copied from manuscript July 21, 2025 Launched in April 2023, the Tropospheric Emissions: Monitoring of Pollution (TEMPO), instrument provides for the first time hourly measurements of atmospheric pollutants over most of North America at high spatial resolution (˜ 2 × 4.75 km2). This evaluation of TEMPO’s first year demonstrates the capability of total formaldehyde column retrievals (ΩHCHO, version 3) at different locations, seasons, and meteorological conditions. The ΩHCHO product is assessed using 36 ground-based Pandora direct-sun measurements from Pandonia Global Network (PGN) as a reference dataset. The 36 PGN sites were chosen for consistency in direct-sun and sky-scan measurement modes. In the first year of operation, TEMPO ΩHCHO exhibit moderate to strong agreement at PGN sites in both measurement modes (R2 = 0.63 to 0.85). TEMPO shows a small bias of -2 ± 20% at lower ΩHCHO (< 1.0×1016 molecule cm-2) and a larger underestimation of -22 ± 5% at higher ΩHCHO (> 1.5×1016 molecule cm-2). TEMPO clearly captures the seasonal variability of ΩHCHO, with summer values exceeding those in winter, spring, and fall by 62%, 45%, and 29%, respectively. TEMPO shows no consistent bias at any time of day with excellent agreement for different meteorological conditions. For all hourly differences between TEMPO and Pandora, 96% fall within 1 × 1016 molecules cm-2. TEMPO provides almost 50% more days with at least one observation compared to observations only at 1 pm. These findings confirm the high quality of TEMPO’s ΩHCHO measurements under a wide variety of conditions and show great promise for future scientific applications.

- In this study, we present a prototype roadmap for integrating remotely sensed observations into decision-making frameworks. Using OPERA VLM products derived from Sentinel-1, we map VLM rates and uncertainties at ~30 m resolution across the Greater Houston-Galveston region.. Our analysis reveals widespread but spatially varying subsidence, with differing impacts on ASTs. We apply a metric to estimate that VLM from April 2016 to November 2023 is predominantly linear, allowing future extrapolation of VLM rates. Combining future sea-level rise (SLR) scenarios with VLM data, we estimate that by 2050, ASTs in the region will experience at least 26.1 cm of relative SLR, with 10 (14.9%) exposed to more than 60 cm. Finally, we illustrate the value of integrating hydrodynamic models with spatially varying relative SLR, finding that flooding hazards are substantially amplified during a simulated Hurricane Harvey–like event under future conditions. Overall, we demonstrate the importance of incorporating high-resolution VLM data into hazard assessments to support near- and long-term decision-making. Our approach provides actionable insights for enhancing resilience to subsidence, RSLR, and associated flooding risks in Greater Houston/Galveston and other vulnerable coastal areas.

- Efforts to quantify and explain individual size distributions (ISD) are prominent in ecological research and potentially for applications to management which increasingly consider ecosystem-scale objectives. We use a nation-wide database of individual size measurements for United States stream fishes paired with species’ traits and test for direct and indirect effects of traits, flow, and land use on the slope of the interspecific ISD. Modeling results show that traits have strong, direct effects on ISD whereas flow and land use primarily indirectly affect ISD via mediation by functional traits. ISDs flatten (i.e., greater abundances of larger-bodied individuals) when environmental conditions favor higher trophic levels, thermal tolerances, and periodic life histories, but steepen (i.e., greater abundances of smaller-bodied individuals) when environments benefit opportunistic life histories. Our framework that incorporates direct and indirect of traits, flow alteration, and land-use on ISD could be expanded to incorporate additional variables that interact with flow regimes (e.g., temperature, physical habitat) to understand and predict how multiple environmental stressors affect ecosystem functions.

- The U.S. Geological Survey (USGS), in partnership with several federal agencies, has now developed and released seven National Land Cover Database (NLCD) products: NLCD 1992, 2001, 2006, 2011, 2016, 2019, and 2021. Beginning with the 2016 release, land cover products were created for two-to-three-year intervals between 2001 and the most recent year. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. NLCD continues to provide innovative, consistent, and robust methodologies for production of a multi-temporal land cover and land cover change database. The NLCD 2021 release is update based, so the Land Cover and Impervious Surface products released in 2019 are unchanged and used directly with NLCD 2021 for change analysis though the NLCD timespan. Science products and the change index are updated and will need to be reacquired to contain the additional 2021 change. These new products use a streamlined compositing process for assembling and preprocessing Landsat imagery and geospatial ancillary datasets; a temporally, spectrally, and spatially integrated land cover change analysis strategy; a theme-based post-classification protocol for generating land cover and change products; a continuous fields biophysical parameters modeling method; and a scripted operational system. The overall accuracy of the 2019 Level I land cover was 91%. Results from this study confirm the robustness of this comprehensive and highly automated procedure for NLCD 2021 operational mapping (see https://doi.org/10.1080/15481603.2023.2181143 for the latest accuracy assessment publication). Questions about the NLCD 2021 land cover product can be directed to the NLCD 2021 land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

- The Github Repository, https://github.com/jodhernandezbe/TRI4PLADS/tree/v1.0.0,, is publicly available and referenced in supplementary information. This GitHub repository describes the computational framework overview, software requirements, model use, model output, and disclaimer. This repository presents a multi-scale framework that combines data engineering with process systems engineering (PSE) to enhance the precision of chemical flow analysis (CFA) at the end-of-life (EoL) stage. The focus is on chemicals used in plastic manufacturing, tracing their flows through the supply chain and EoL pathways. Additionally, this study examines potential discharges from material recovery facilities to publicly owned treatment works (POTW) facilities, recognizing their relevance to human and environmental health. Tracking these discharges is critical, as industrial EoL material transfers to POTWs can interfere with biological treatment processes, leading to unintended environmental chemical releases. By integrating data-driven methodologies with mechanistic modeling, this framework supports the identification, quantification, and regulatory assessment of chemical discharges, providing a science-based foundation for industrial and policy decision-making in sustainable material and water management. The attached file CoU - Metadata File.xlsx contains the datasets to build Figure 3 and describe a qualitative flow diagram of methyl methacrylate from manufacturing to potential consumer products generated from the Chemical Conditions of Use Locator methodology (https://doi.org/10.1111/jiec.13626).

- Data available in Zenodo via doi: 10.5281/zenodo.16318572 Headwater streams play critical roles in hydrologic and biogeochemical processes and functions, yet their spatial distribution and land cover context remain poorly understood at continental scales. Building from a high-resolution conterminous United States (CONUS) hydrography network dataset, we quantified the spatial extent, density, and upstream catchment characteristics of headwater stream segments across the CONUS. We identified approximately 8.4 million kilometers of headwater streams – 77% of the total stream network is comprised of headwaters – nearly double the total length represented in prior estimates. Stream density varied fivefold across regions, from under 1 km•km-² in arid basins to over 5 km•km-² in humid, forested areas. Over 73% of the CONUS landmass drains from headwater streams. The majority of headwater stream length occurred in forested and cultivated catchments across the CONUS, while substantial regional differences were evident for headwater stream distribution in other land cover classes (e.g., wetlands, urban areas, shrublands, and herbaceous-dominated catchments). Our analysis provides the first continental-scale, high-resolution characterization of headwater streams, offering new insights and opportunities for hydrologic modeling, ecological assessments, and environmental policy. Plain Language Summary: Headwater streams—the small streams at the origins of rivers—are essential for clean water and healthy ecosystems. But because they’re small and often hidden, they've been hard to identify and delineate nationwide due to inconsistent data and definitions. This study combined existing data sets and added new analyses to consistently map headwater streams and the drainages across the conterminous United States (CONUS). Analysis of these data revealed that headwater streams are nearly twice as widespread as previously shown, totaling 8.4 million kilometers. We also found that most land drains to a headwaters stream, and most stream kilometers are headwaters. Human alteration of the landscape for agriculture and urbanization also reduces the prevalence of headwater streams. This is the first time headwater streams have been identified on available maps with such granularity and spatially explicit detail across the CONUS, offering a powerful new tool to guide conservation and policy.14 days ago

- Drying has a major impact on pattern and process in streams, particularly in small or headwater streams. Such streams that dry recurrently are called non-perennial streams and represent most of the channel length across river networks. In spite of their prevalence, non-perennial streams are vastly underrepresented in existing stream gaging networks and in maps and hydrographic datasets. However, diverse and spatially extensive datasets of surface water presence observations exist as well as recently developed mobile applications that could help fill the data gap in characterizing the spatial extent of non-perennial streams. Hydrological data from perennial and non-perennial reaches were compiled from a series of studies on headwater streams to expand available data for mapping and modeling efforts in the United States. Hydrologic data within this compilation include visually recorded observations of hydrological status (dry, isolated pools, interstitial flow, and continuous surface flow), point measurements of discharge (cubic meters per second), and logger-based measurements for the timing and duration of streamflow and drying. These data were compiled across a series of studies on headwater streams (drainage area ~2.6 km2 or less) and were used to characterize their hydrology. Hydrologic data within this compilation are organized into files based on type of hydrologic data and study area. The types of hydrologic data include visually recorded observations of hydrological status (dry, isolated pools, interstitial flow, and continuous surface flow), point measurements of discharge (cubic meters per second), and logger-based measurements for the timing and duration of streamflow and drying. The study areas included in the compilation include headwater streams in Kentucky (Robinson Forest), Illinois (Shawnee National Forest), Indiana (Hoosier National Forest), New Hampshire (Dodge Brook), New York (Balsam Lake Mountain), North Dakota (Pipestem), Ohio (Congress Run, Edgewood Preserve, Edge of Appalachia, Wayne National Forest), South Carolina (Carolina Sandhills, Sugarloaf Mountain, Sumter National Forest Enoree and Long Cane Districts), Tennessee (Big Ridge), Vermont (Hinesburg), Washington (Mt.

- Data are biological and chemical in nature. They describe organismal responses to copper treatments. The abstract can be found below. Copper can be toxic to aquatic organisms at high concentrations and has been previously used successfully to control zebra mussels (Dreissena polymorpha). Because copper’s toxicity changes with water chemistry, using the same copper concentration in different waterbodies could yield different outcomes. We demonstrate how measuring water chemistry parameters and using the Biotic Ligand Model (BLM) and multiple linear regression (MLR) models can predict a suitable, site-specific copper concentration for management. We exposed zebra mussel adults and non-target organisms to varying concentrations of copper over 10 d in a mobile laboratory. We found that one non-target species, Daphnia magna, had a 50% chance of survival at 9.50 µg Cu/L (i.e., the 50% lethal concentration, LC50), within our BLM-predicted range of 3.38–16.95 µg Cu/L LC50 values. In the future, managers could make similar predictions and tailor their copper concentrations to their management goals. We also measured zebra mussel larvae mortality at copper concentrations ranging from 0 to 191 µg Cu/L. While those results were inconclusive, we present the results of this work as a foundation for future projects. Our study underscores the importance of developing site-specific copper concentration recommendations and demonstrates the potential utility of the BLM and MLR approaches for informing those recommendations.

- Urban environments often contain mosquito species that are responsible for transmitting medically important pathogens to humans. Large disturbance events, like hurricanes, can devastate large urban areas, especially in the tropics; however, little data exist for how these storms affect vector populations. During September 2017, Hurricanes Irma (category 5) and Maria (category 4) passed in proximity to the island of Puerto Rico, USA, causing significant damage to the built environment and significantly altering the abiotic environmen,t including the removal of the plant canopy. We measured adult Aedes aegypti populations, the main vector of several pathogens, and larval containers across eight neighborhoods in San Juan, the capitol, that varied in socioeconomic status (SES) across eight sampling periods over 17 months following the storms. We also analyzed the nutrient content (%N, %C, C:N) and stable isotopes (δ15N, δ13C) from adults and isotopes from containers to assess how the nutrient environments changed post hurricanes. Mosquito population sizes were invariant throughout sampling, although more females were collected in lower SES neighborhoods that were more enriched in δ15N compared to higher SES locations. We did find that the storms altered the stoichiometric content of adults, with lower C:N values right after compared to a year later; larval containers showed an increase in δ15N through time. The lack of any interactive effects of the storms on specific neighborhoods suggests that Irma and Maria affected all locations equally, however, the storms altered the nutrient content of both adults and larval containers, a result with implications for pathogen transmission.

- The GitHub site contains the code and data to run two methods as shown in the manuscript. The first quantifies external load, internal load, and source attributed impact on cyanoHAB severity. This method was written using R language (version 4.2.2). The second method maps potential legacy P stores in upstream watersheds of Lake Mendota, WI (USA) and estimates the total P load per contributing area across watersheds. This method was written using Python language (version 3.8.5) & GeoPandas (version 0.8.2). 1. Impact_model_method The impact model method is a series of sequential programs that take original source data, performs quality control checks and re-formats the data as new data files for input into the impact model. The Impact_model_method folder has all programs used in this method. All code is written in R Markdown format (.Rmd). Here's the order to run the R programs and achieve the same results as shown in the manuscript: cyanoHAB_severity.Rmd - calculates cyanoHAB severity (as Chl-a and cyanobacteria density) TotalP_external_atmdep.Rmd - calculates external total P loads from atmospheric deposition TotalP_external_inflows.Rmd - calculates external total P loads from inflows (streams) TotalP_external_all.Rmd - calculates the sum of external total P loads (streams + atmospheric deposition) EpiVolume.Rmd - calculates the change in volume of the epilimnion using temperature profiles TotalP_water.Rmd - calculates the total P concentration in the epilimnion, total P concentration in the hypolimnion, and ratio of total P in hypolimnion to epilimnion (as alternative indicator of internal P load) TotalP_internal.Rmd - calculates internal total P loads (or alternatively the ratio of totalP_hypo:totalP_epi) Model_inputs.Rmd - prepares the data as input for impact modeling (defines predictor and response variables) Impact_model.Rmd - performs the statistical modeling for impact analysis on cyanoHAB severity by source (external vs internal) and outputs the partitioned sum of squares for each predictor term 2. Spatial_model_method The spatial model method takes original source data, performs quality control checks and re-formats the data as new data files for input into the spatial model. The model maps potential legacy P stores in upstream sub-watersheds, and quantify total P load per contributing area across sub-watersheds. All programs used in this method are provided in the Spatial_model_method folder. All code is written in Python language (.py or .ipynb). The specific order in which programs should be run to achieve the same results as shown in the manuscript is as follows: HydroGraph_functios.py - performs the network mapping of sub-watersheds upstream of the inflows to the lake watershed_analysis.ipynb - calculates the P export per contributing area for each of the upstream sub-watersheds OHSA.py - performs the optimized hot spot analysis for determining statistically clustered stream monitoring sites with consistently high P concentrations.

- Clean Water Act (CWA) coverage extends to certain wetlands, including those with a continuous surface connection to relatively permanent tributaries. However, limited information is available to estimate the national extent of wetlands potentially afforded CWA coverage. To address this data gap, we identified conterminous US (CONUS) palustrine wetlands connected by an exploratory 150-m buffer to a high-resolution CONUS-wide stream network hydrography dataset, a reasonable and defensible proxy for a continuous surface connection between wetlands and relatively permanent waters. Nationally, 79% (23.1 Mha) or 66% (19.3 Mha) of the nation's CONUS freshwater palustrine wetlands are potentially connected to the stream network, depending on whether a more inclusive or exclusive flow permanence network is analyzed. Conversely, 21% (6.1 Mha, roughly the area of West Virginia) or 34% (9.9 Mha, greater area than Indiana) of CONUS wetlands may be outside this buffer. Results for individual states varied widely based on stream and wetland density. States with a low relatively permanent stream density had fewer buffer-connected wetland resources (e.g., 21% in North Dakota). Similarly, wetlands in southwestern states and other states with abundant ephemerally flowing streams were also not connected via the applied buffer. Geospatial data limitations and assumptions (e.g., omission errors, presumed presence of a surface connection) suggest the estimated extent of wetlands with potential continuous surface connections to federally covered waters are likely to be substantially smaller than reported here. Nonetheless, the analyses herein provide insights for local, state, and tribal stakeholders to consider in managing their wetland resources.

- This study sought to examine whether mild preexisting allergic airways disease enhances the response of the lungs to burn pit smoke emissions. The findings indicate that exposure to house dust mite (HDM) antigen sensitizes the mouse lungs to make them more susceptible to burn pit smoke-induced dysfunction, in both the inflammatory response to burn pit smoke and in the accumulation of airway mucus. This suggests that changes in cilia and mucociliary clearance (MCC) induced by asthma that are amplified by inhalation of burn pit smoke, followed by a feedback loop of enhanced inflammation induced by the accumulating mucus, appears a likely mechanism.

- The exposome represents the totality of chemicals present in an organism’s tissues. To understand how external exposure, originating from the contamination of water and sediment, relates to the internal exposure of fathead minnow (Pimephales promelas, FHM), a model small fish species, we conducted a 21-d caging study at four field sites in the Great Lakes with different pollution loads and patterns. We determined the FHM’s body burden, total water concentrations and freely dissolved concentrations in sediment pore water of 456 organic micropollutants. Up to 123 micropollutants were detected in water, 165 in sediment and 153 in FHM. Chemical concentrations at the different study sites varied largely, with one site impacted by a municipal wastewater treatment plant having the highest overall concentrations, with a prevalence of personal care and household products, pharmaceuticals and pesticides. The other sites, associated with past industrial inputs, were characterized by elevated concentrations of legacy contaminants, including polycyclic aromatic hydrocarbons. We observed a moderate agreement of contamination patterns in fish compared to chemicals found in the sediment, while the water phase was dominated by more hydrophilic chemicals often not present in the fish. The study shows the degree of predictability of the exposome in fish that may be expected based on chemical concentrations in water and sediment based on equilibrium partitioning and provides evidence for the need of body burden analysis to comprehensively understand an organism’s exposure to environmental contaminants.

- Per- and polyfluoroalkyl substances (PFAS) are chemicals of emerging concern that potentially pose risks to human and environmental health. In May–Oct 2018, sediment and passively collected surface water samples were collected from 62 tributary sites of the Laurentian Great Lakes with site catchments spanning gradients in land cover. Discrete samples of sediment and time-integrated surface water samples collected with polar organic chemical integrative samplers (POCIS) were analyzed for 23 and 34 PFAS, respectively. Concentrations of individual PFAS in sediment and surface water varied substantially among sites from below detection to 20,800 ng kg-1 and 247 ng L-1, respectively. Elevated PFAS concentrations occurred in urban watersheds and downstream of airports and wastewater treatment plants (WWTP). Of all target compounds, PFOS was the most frequently detected in sediment (56 of 62 sites) and had the highest median concentration (132 ng kg-1). PFOA, PFHxS, PFOS, PFHpA, and PFNA were detected in all 60 surface water sites, with median concentrations of 5.9, 5.2, 4.6, 3.7, and 1.3 ng L-1, respectively. Compounds with 8–14 fluorocarbons comprised a larger proportion of sediment PFAS than compounds with 4–7 fluorocarbons, whereas compounds with 4–7 fluorocarbons were dominant in surface waters. Watershed attributes, including urban land cover and WWTP flow fraction were positively related with PFAS sum concentrations in sediment and surface water. Collectively, these results highlight the relation PFAS occurrence has with human activities and documents widespread low-level PFAS contamination across the Great Lakes basin.

- This is the data for Heat, Humidity, and Adverse Birth Outcomes: Quantification of Projected Risks in the Contiguous United States Research increasingly demonstrates relationships between higher apparent temperatures, inclusive of heat and humidity, and greater rates of preterm birth (PTB), term low birth weight (tLBW), and stillbirth cases. Through leveraging available epidemiological studies, we estimated the change in burden of these outcomes across the contiguous United States (CONUS) and throughout the 21st century during warm season months (i.e., May through September or October). We projected an additional 4,500 PTBs, 3,800 tLBWs, and 420 stillbirths at 1°C of CONUS warming attributable to changes in apparent temperature relative to baseline climatic conditions (1985-2006). These cases increased to 22,000 PTBs, 18,000 tLBWs, and 2,000 stillbirths with 4°C of warming relative to the baseline. We projected the most significant changes in per capita rates to occur in Gulf Coast states, where baseline risks currently are among the highest in the CONUS. Across the three outcomes, we projected an increase in short-term healthcare costs following birth of approximately US$690 million annually at 1°C of warming, increasing to US$3.3 billion annually at 4°C (2023 dollars). When considering the economic burden of the infant deaths resulting from PTB and tLBW cases, we projected additional costs on the order of US$3.9 billion annually at 1°C, and US$35.8 billion annually at 4°C. Due to data availability, our valuation could not account for potential longer-term health and productivity implications or pain and suffering that families may experience following the adverse birth outcomes analyzed.

- An innovative and sustainable immobilization remediation strategy concept for managing per- and polyfluoroalkyl (PFAS)-impacted soils was investigated at bench-scale. This approach involved the use of protein-based materials that are often considered waste products to serve as chemical (stabilization) sorbents, followed by cement binder (solidification), to explore their potential as a solidification/stabilization (immobilization) remediation process. The results of this immobilization study indicated that GAC, as a chemical stabilization agent, effectively reduced the leachability of PFAS compounds from an impacted soil. Minimal additional reduction in leachability was observed upon cement addition (solidification). While the blood meal sorbent was less effective than GAC as a stabilization agent, it did decrease leachability for the majority of the detected PFAS compounds in the soil. However, some of the PFAS compounds exhibited increased leachability post-treatment. Addition of cement as a solidification agent generally decreased the leachability for most of the detected PFAS compounds. Overall, this study suggests that protein-based sorbents, specifically blood meal, with solidification by cement addition may be a novel and sustainable remediation approach for certain PFAS-impacted soils, warranting further investigation into optimization strategies and potential field-scale applications.

- The Community Multiscale Air Quality (CMAQ) model version 5.4 (epa.gov/cmaq) was applied with 12 km sized grid cells for a domain covering the conterminous U.S. and areas offshore. The vertical atmosphere was resolved up to 50 mb with 35 layers. Vertical layers were thinner nearest the surface to best resolve diurnal fluctuation in the surface mixing layers. Lateral boundary inflow was extracted from a hemispheric scale simulation for the same year. Meteorological inputs were developed with the Weather Research and Forecasting model version 3.8.1 applied with the same grid domain as the photochemical model. The Pattern Constructed Air Pollution Surfaces (PCAPS) model has been applied for complex sector-specific emissions scenarios for stationary and mobile sources and predicted air quality results consistent with more sophisticated models. PCAPS version 1.1 was applied for each year between 2024 and 2031 with year-specific offshore wind project and EGU emissions. PCAPS was also applied using the same offshore wind and onshore EGU emissions for the 2026 and 2055 scenarios simulated with CMAQ to allow for a direct comparison of results.

The vertical atmosphere is resolved with 35 layers extending from the surface to the tropopause with finer resolution in the planetary boundary layer to better capture diurnal variation in mixing height. The Carbon Bond 6 revision 3 gas phase chemical mechanism, ISORROPIA II inorganic aerosol thermodynamics, aqueous phase cloud chemistry, and wet and dry depositional processes are included in the simulation. Primary organic aerosol is treated as non-volatile. SOA formation is described by semi-volatile partitioning of lumped gas-phase groups that include benzene, toluene, xylenes, naphthalene, monoterpenes, isoprene, and sesquiterpenes and particle-phase oligomerization. AqSOA is formed from glyoxal, glyoxal analogues (methylglyoxal and glycolaldehyde), and isoprene epoxydiols. Biogenic emissions are estimated using the Biogenic Emission Inventory System (BEIS) version 3.6.1 Anthropogenic emissions are based on the 2016 emissions modeling platform developed by the U.S. EPA. Lateral boundary inflow is extracted from a coarser scale model simulation that covered the northern hemisphere. Meteorological inputs from the Weather Research and Forecasting (WRF) model version 3.8 are used to develop biogenic emissions and drive atmospheric dynamics using the same domain and projection specifications as the CMAQ model simulation.

- Data release for integrating remotely sensed surface water dynamics in hydrologic signature modelingVariability in river discharge, particularly very high flow and low flow conditions, has far-reaching environmental and economic consequences. The retention of water in surface storage, concentrated in lakes, ponds, wetlands, floodplains, and temporary water in flood prone areas, can potentially contribute to flow generation and flood regulation. However, the impact of surface water storage on river discharge can be challenging to isolate and quantify. A suite of hydrologic signatures were generated for 72 gages across the conterminous United States. The hydrologic signatures were selected to characterize all flows as well as isolating high and low flows, and machine learning models were developed to explain watershed variability in signature values. Wetland related variables, including multi-sensor-based surface water extent and hydroperiod, were compared with other drivers, including climate, topography, and land cover. An improved understanding of how surface water dynamics influence river discharge can be used to improve the resilience of river systems to climate extremes.

- These data were collected by the EPA Toxic Element Bioavailability Laboratory and consists of lead (Pb) and/or arsenic (As) mouse tissue, soil, aqueous soil leachate, and spectroscopy data. The mouse-based assay for assessment of lead and arsenic in vivo mouse bioavailability in soil and dust is a critical tool needed to improve our understanding of the factors affecting the metal’s uptake across the gastrointestinal barrier and to evaluate the efficacy of methods used to remediate lead and/or arsenic contaminated media. The mouse assay has been optimized to yield accurate, reproducible, and reliable estimates of the in vivo mouse bioavailability of lead and/or arsenic in soil and dust. The reported Pb/As data is used to assess the total, bioaccessible, and bioavailable concentrations resulting from exposure to soils. These data were collected using EPA Methods 1340, 3050b, 6010d, and 6020b. These quantitative characterization data are then paired with X-ray absorption spectroscopy data that is used to deduce the valence, coordination environment, and mineral/sorbed phase of the element of interest. These data are collected at a synchrotron facility by our team and then processed at EPA ORD using previously established methods (e.g., Sowers et al., 2023).14 days ago

- This EnviroAtlas dataset contains projected change in 30-year normals in maximum temperature, minimum temperature, evapotranspiration, and precipitation, for Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, American Samoa, Guam and Commonwealth of the Northern Mariana Islands. This dataset was created using the NASA Earth Exchange-Global Daily Downscaled Projections (NEX-GDDP), developed using Global Climate Models (GCMs) runs conducted under the Coupled Model Intercomparison Project Phase 6 (CMIP6) across four scenarios, known as Shared Socioeconomic Pathways (SSPs). The four SSPs involved in this project are SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8.5. The raw NEX-GDDP-CMIP6 data has a spatial resolution of 0.25 degrees and a daily temporal resolution. The NEX-GDDP-CMIP6 data was processed to calculate projected changes in six climatic variables for each season (fall, spring, summer, winter) and annually for five 30-year periods: recent history (1976-2005) to near-term future (2025-2054) recent history (1976-2005) to mid-century (2045-2074) recent history (1976-2005) to end-of-century (2070-2099) near-term future (2025-2054) to mid-century (2045 to 2074) near-term future (2025-2054) to end-of-century (2070 to 2099) The six climatic variables included in the dataset are change in: total precipitation [in and fraction] total potential evapotranspiration [in and fraction] maximum temperature [degF], and minimum temperature [degF]. This data was then used to produce an NEX-GDDP-CMIP6 ensemble median for each variable for each HUC12. Not all GCMs downscaled in NEX-GDDP-CMIP6 had availability for every variable and scenario combination. Due to low historical values in precipitation and potential evapotranspiration, the data for Alaska is not available in fraction unit.

- Transportation of damaged, defective, or recalled (DDR) lithium-ion batteries (LIBs) of is an important emerging issue as the use of electronic vehicles (EVs) and other LIB based items proliferate. Additionally, since these battery cathodes are made up of lithium nickel manganese cobalt oxide (NMC), lithium iron phosphate (LFP), lithium manganese oxide (LMO), and lithium cobalt oxide (LCO), there is an interest in the safe recovery of critical minerals, such as lithium, cobalt, and nickel, and other scarce resources from this source. These DDR LIBs must be de-energized to safe voltage levels, identified as below 1.0 V, to reduce the risk of fire and explosion during transport from crash sites, floods, wildfires, etc. Sodium chloride (NaCl) solutions are typically used to electrochemically discharge LIBs, but these solutions can cause battery terminals to corrode, leading to solid residue, fluoride ion buildup, release of toxic gases to the air, and release of corrosion solids and battery electrolytes into the solution. Because of these drawbacks, alternatives for discharging DDR LIBs must be sought. In this project, different LIB discharge methods identified in the literature will be tested for their ability to adequately de-energize DDR LIBs to a safe level, and the environmental effects of these methods (e.g., off-gassing, waste, etc.) will be evaluated to find an effective, safe, and environmentally-sound replacement for NaCl solutions. The potential alternatives that have been identified are iron sulfate (FeSO4), sodium bicarbonate (NaHCO3), magnesium chloride (MgCl2), sodium hydroxide (NaOH) and sugar. These were specifically identified as each is readily available are common grocery or home goods stores and would thus be available to on-scene coordinators responding to a disaster scene. The environmental impact of these different discharging methodologies will be evaluated via the analysis of any byproduct formation and monitoring of physical battery condition during discharge.14 days ago
- Newly recovered xenoliths from the modern backarc region in southern Peru were collected to investigate the metasomatic history of the northern Altiplano lithosphere and improve constraints on the formation of recent potassic magmatism in the region. The xenoliths described here were collected from a Quaternary latite lava flow near Huarocondo, Peru and include calcite-bearing phlogopite-orthopyroxenites, harzburgites, a wehrlite, and a phlogopite schist. Xenoliths were analyzed for C and O stable isotope ratios of calcite, H stable isotope ratios of phlogopite, and Sr isotope ratios of calcite, silicates, and phlogopite separates. Mineral chemical analyses where performed on orthopyroxenite and harzburgite xenoliths via electron microbrobe, and bulk rock trace element analyses of all xenoliths were performed via ICPMS. New bulk rock major and trace element analyses of four Quaternary lavas flows belonging to the Rumicolca Formation are also presented.

- Our research used a combination of laboratory-based acute aqueous metals exposures and RNA-sequencing technologies to identify a gene-based means to extrapolate metals toxicity across a range of fish taxa. For Phase 1 of our project, we compared transcriptome changes in caudal fin, gill and liver of juvenile Rainbow trout (Oncorhynchus mykiss) exposed to cadmium (Cd), copper (Cu), or zinc (Zn) at 17, or 50% of LC50 concentrations for 24 and 96 hours to controls. These experiments allowed us to test for conserved responses to the metal exposures, and to test which metal produced the most coherent gene expression profile indicative of a defined mode of action. During Phase 2, we exposed juvenile Chinook salmon (Oncorhynchus tshawytscha) to the selected metal (Zn) to begin to ascertain the extent to which the mode of action identified was conserved among salmonids.24 days ago

- Dataset: Predictions of Cyanobacteria and Microcystin in Lakes across the Conterminous United StatesWith increasing concerns about freshwater cyanobacteria blooms, there is a need to identify which waterbodies are at risk for developing these blooms, especially those that produce cyanotoxins. To address this concern, we developed spatial statistical models using the US National Lakes Assessment, a survey with over 3,000 spring and summer observations of cyanobacteria abundance and microcystin concentration in lakes across the conterminous US. We combined these observations with other nationally available data to model which lake and watershed factors best explain the presence of harmful cyanobacterial blooms. We then used these models to estimate the cyanobacteria abundance and probability of microcystin detection in 124,500 lakes across the CONUS. This dataset includes the compiled data used to generate the models and the dataset used to generate prediction for a much larger population of lakes. The data package includes two tabular data files, two tabular metadata files, and one methods document.44 days ago

- The City-based Optimization Model for Energy Technologies (COMET-NYC) is an energy system modeling tool developed by the U.S. Environmental Protection Agency. COMET is applied to New York City to support long-term, metropolitan-scale air, climate, and energy planning. Built on the internationally recognized TIMES modeling framework, COMET-NYC identifies the least-cost mix of technologies and fuels required to meet projected energy demands from 2010 to 2055 across NYC’s buildings, transportation, and electricity sectors. COMET-NYC uses a scenario-based optimization approach to simulate the deployment of energy technologies under various assumptions, policies, and constraints. It incorporates local data sources to estimate and calibrate energy consumption and emissions at the borough level. It tracks both greenhouse gases (GHGs) and criteria air pollutants, supporting city-level climate and air quality policy evaluation. The model includes detailed modules for the residential, commercial, industrial, and transportation sectors, accounting for current and future technology costs, fuel types, and efficiency parameters. It uses linear programming to minimize system-wide costs while meeting energy service demands and emissions targets. COMET-NYC supports both retrospective analysis (e.g., calibration to 2010, 2015, and 2020) and future scenario exploration, such as electrification strategies. Two versions of the model are included in this dataset: v15.0.9, which underpinned emissions reduction planning during the 2023–2024 NYC budgeting cycle, and v16.0.1, which includes updated buildings data and improved calibration. The documentation included various appendices for background data to build COMET-NYC. Appendix A through F are included in this dataset. Appendix A provides time slice documentation; Appendix B provides PLUTO 2010 data; Appendix C provides original 2014 building end-use demand splits for NYC; Appendix D provides EIA 2023 building technology data; APPENDIX E provides 2015 NYMTC SEDS population and employment forecasts; and APPENDIX F provides Documentation of Transportation Sector Emission Factors Updates and related input datasets for MOVES model.

- The United States Environmental Protection Agency (US EPA) conducts extensive research to enhance the scientific foundation for national environmental decision-making. In this context, US EPA has developed COMET (City-based Optimization Model for Energy Technologies) to capture the whole energy system at the city level over a user-defined analyses timeline, from the extraction of primary resources to conversion into useful energy to meet end-use service demands. COMET accounts for the investment and operation costs, as well as greenhouse gas (GHG) emissions and other air pollutants, of alternative technology pathways meeting long-term energy demands in the buildings, transportation, and waste sectors. In this way, COMET enables users to explore, compare, and optimize energy technology solutions over the coming decades, especially for medium- and large-sized cities working to achieve energy optimization objectives and emissions reduction targets. Model results reveal how the energy system can be balanced under different scenarios and assumptions, as well as how system costs and emissions change with respect to those scenarios. With this information, city officials and their stakeholders working to pursue energy planning within their borders are positioned to make more informed policy and program decisions. An open-source version of COMET designed for use by local planning, energy, or environmental agencies in any city is developed – will be called “Generative COMET”. The Generative COMET model incorporates innovative features that streamline the calibration process to align with official energy or GHG inventories, based on the level of detail available in city-level data. It provides cities with a versatile framework for analyzing energy and GHG emission scenarios, with different levels of data granularity and city-specific conditions. Its modular and adaptable structure enables cities of all sizes to explore customized strategies for meeting energy demands and achieving GHG reduction targets effectively. This dataset is associated with the following publication: Kaplan, O., K. Vaillancourt, M. Pied, R. Chaffanjon, F. Pedroli, D. Cooley, and N. Dietsch.

- The purpose of this dataset was to compile, in a single location, the landfilled solid waste quantity data from various state government reports, repositories, or databases. The development of the dataset has several motivating factors, including to understand the amounts and types of wastes that are disposed in non-hazardous waste landfills and to understand the availability of these types of data across our United States. This dataset only contains tonnages (i.e., weights or masses in U.S. tons) of disposed materials/wastes in as much detail as the State provides. It does not include amounts of wastes recycled, composted, incinerated, transferred, or generated. For instance, a landfill may receive ash that comes from the incineration of municipal solid waste (MSW; e.g., waste-to-energy ash). The amount of incinerated ash that is landfilled would be reported here but not the amount of waste the incinerator received.14 days ago

This experiment was designed to target hippocampal and hypothalamic neuromodulation to determine the role of indoleamines, monoamines, and glucocorticoids in mediating the systemic and pulmonary effects to ozone exposure.14 days ago
- Dispersion effectiveness data for petroleum oils in low and hypersaline waters. Chemical dispersant formulations typically provide maximum oil dispersion in waters between 30-40 ppt (parts per thousand) salt content, which encompasses typical 35 ppt ocean salinity. Ocean salinity can vary locally, from very low values due to freshwater river inflows or ice melt, to extremely high values during freeze up periods or within natural brine pools. In this study, the influence of salinity (0.2-125 ppt) on dispersion effectiveness (DE) was evaluated for three oils and four dispersants using the baffled flask test (BFT) and oil droplet size distribution (DSD) measures. Tank-scale dispersions support the laboratory-scale results of DSD. Light and medium crude oils were effectively dispersed over a wide salinity range using the BFT. However, dispersions exhibiting similar DE values possessed a wide range in DSD metrics, suggesting that the latter offers useful information for spill planning and understanding the transport and fate of spilled oil. This dataset is associated with the following publication: Conmy, R., D. Sundaravadivelu, B. Schaeffer, B. Robinson, T. King, and R. Grosser.

- Healthy seagrass beds were once found throughout the shallow areas of Narragansett Bay, R.I. but have largely disappeared due to infilling, nutrient pollution, and disease. In Greenwich Bay, a highly developed embayment within Narragansett Bay, the widgeon grass, Ruppia maritima, has colonized an area on the northern shore once dominated by the eelgrass, Zostera marina. This area is sandy, which may allow groundwater seepage. This observation is consistent with our understanding of Ruppia ecology. This genus is extremely salinity tolerant and may be more nutrient tolerant than Zostera. To experimentally explore this phenomena, two, 6-week microcosm experiments were conducted. For both experiments, shoots of sub-aquatic vegetation (SAV; Ruppia or Zostera) were planted in sediment in 10 cm plastic tubes. These tubes were placed in large flow-through water tanks outside on a dock to keep temperature consistent. experiments, shoots of SAV were planted in sediment in 10 cm plastic tubes.

- Unlike many estuaries, Narragansett Bay nutrient inputs are dominated by point sources. After a large fish kill in 2003, large management actions have been implemented to reduce nitrogen loads to 5 mg/l by implementing fixed film activated sludge treatment (on-line 2013 and 2014) and preventing combined sewage overflow by creating large interceptor tunnels (2008 = phase 1, 2014 = phase 2). These data were collected to assess conditions after these major management upgrades had been implemented. With previously published data, it may be possible to assess change before, during and after sewage treatment upgrades.14 days ago

- The project entailed deployment of an on-site on-demand peracetic acid (PAA) disinfectant pilot system at a combined sewer storage facility in Akron, OH (Akron Rack 40). The pilot system was constructed and wet tested in Cincinnati, OH at EPA facilities and transported via trailer to the Akron site. The system produced a dilute peracetic acid disinfection solution via reaction of two industrial detergent powders (TAED - Tetraacetylethylenediamine and SPC - Sodium percarbonate) in a water matrix. The disinfectant was injected into a simulated combined sewer overflow (CSO) stream via mixing Little Cuyahoga River water with raw sewage drawn from the Akron sewer system. Samples were drawn after 5-minute, 10-minute and 15-minute contact time to determine efficacy of the system at reducing pathogens as primarily determined through E. coli inactivation. Sample sets from two trials were also analyzed for inactivation of Heterotrophic bacteria and Bacteriophage MS2 as surrogate for viral inactivation.14 days ago

- Since the national validation of the sponge-stick based method for detection of Bacillus anthracis spores in environmental samples, there have not been focused efforts to address the low throughput nature of the method, which processes only one sample at one time. Sample processing remains a serious bottleneck for rapidly analyzing large numbers of samples expected from a biological warfare attack. Therefore, we developed a high-throughput method to simultaneously process multiple sponge-stick samples to be better prepared for rapid response and recovery after wide area anthrax incidents. In this method, sponges are placed in 50 mL tubes containing 25 mL buffer and shaken to release spores, after which the buffer is recovered for analysis. We determined that an additional rinse step, conducted in the same tubes with 10 mL buffer, further increased spore recovery from sponge-stick by approximately 10%. We determined that orbital shaking and multi-tube vortexing were both more effective than reciprocating shaking for recovering spores. We conducted simultaneous processing of up to 12 sponge-stick samples and demonstrated comparable spore recovery efficiencies to the traditional low-throughput stomacher-based method (approximately 60% recovery at 102-spore level and 75% recovery at 104-spore level for both methods in three replicate experiments, P > 0.05 for two-tailed T-tests for each experiment and spore level). We also demonstrated that our high-throughput method could be integrated with Rapid Viability-Polymerase Chain Reaction (RV-PCR) analysis and could detect levels as low as 40 spores per sponge even when challenged by a PCR particulate contaminant.

- A laboratory-based microcosm study was conducted from September 2023 to July 2024 by the Office of Research (ORD) Cincinnati Lab (ORD-CESER-LRTD-CAISB). QA Category B data was generated following established methodologies and quality-assurance procedures. ORD clearance policy requirements for internal technical review, quality assurance review and supervisor reviewer/approval were met. This data is to be published on ScienceHub following satisfaction of EPA ORD policies. No interpretation of the data is provided. The results of this study will be described in detail in a publication subjected to external, expert peer review. Sediments, collected from the Lower Coeur d’Alene Basin (CDA) in the Bunker Hill Mining and Metallurgical Complex Superfund Site (Bunker Hill), were used in microcosms set up and monitored by ORD Cincinnati staff. The study was designed to evaluate the impact of repeated wetting and drying cycles on sediment porewater metal concentrations in the Lower CDA. Sediments were subjected to three wetting-drying cycles, and porewater was sampled throughout the duration of the experiment. Two sediment types were subjected to two different treatments (Permanently wet vs wet/dry) with 3 replicates of each, yielding 12 total microcosms. Each wetting-drying cycle lasted 30 days and was followed by 30 days of drying (Figure 1). This data package summarizes sediment, sediment porewater and surface water results including total metal concentrations in sediment and sediment porewater, dissolved organic carbon (DOC) concentrations, dissolved iron and sulfide, UV absorbance at 254 nm, YSI measurements of porewater, sulfate concentrations, times series data of redox potential (Eh), and lead (Pb) speciation analysis of select samples. See attached QA Memo detailing QA/QC procedures used for each parameter and a schematic of the microcosms.14 days ago

- Publication of EPA’s Nutrient Inventory is a critical step towards thorough mapping and accounting of sources of N and P to US landscapes. However, summaries of nutrients within accumulative watersheds are needed to develop accurate watershed-level nutrient budgets and relate landscape inputs to instream nutrient concentrations. This subproduct will accumulate the Nutrient Inventory across available years for all streams and lakes within the medium resolution National Hydrography Dataset Plus version 2 (NHDPlus), i.e., 2.6 million stream segments and nearly 400,000 lakes across the conterminous US. These data will allow OW to easily and rapidly identify the dominant sources of N or P for any stream segment or lake in the US. Further, these data will be made accessible through the EPA’s StreamCat and LakeCat datasets and a soon-to-be released online database and an application programming interface (API). This database and API will make nutrient watershed accumulations readily accessible and easily integrated by a variety of OW programs and tools. Finally, the accumulated nutrient data will serve as the basis for a multiple proposed StRAP subproducts and models in SSWR.401, SSWR.404, and SSWR.405. These data will contribute directly to OW, region, and state efforts to identify and reduce non-point nutrient sources. Having spatially explicit data about nutrient sources and loads can help target and inform restoration and conservation efforts, as well as more formal TMDLs, nutrient reduction plans, and groundwater management approaches. This subproduct will produce a database of accumulated nutrient values for at least 2.6 million stream segments and 400,000 lakes of the medium resolution National Hydrography Dataset Plus version 2 (NHDPlus). These data will be made accessible through the StreamCat and LakeCat datasets. They will also be made available as an online database with application programming interface (API) that will facilitate data acquisition and use by OW and state partners. This database will provide a state-of-the science accounting of nutrient sources that drain to all streams and lakes in the conterminous US. It will allow EPA and state partners to identify dominant sources of N and P to individual waterbodies and will greatly facilitate nutrient reduction strategies and planning.14 days ago

- Polychlorinated biphenyls (PCBs) are a group of 209 chemicals with varying chlorine substitutions that influence their absorption, distribution, metabolism, and excretion (ADME). These differences affect how PCBs behave in the body, including their lipophilicity, tissue distribution, and biological half-life. Humans and animals can absorb PCBs through inhalation, ingestion, or skin contact, with the compounds accumulating in fatty tissues and eliminating at variable rates—some over decades. Pharmacokinetic (PK) models help estimate internal doses and assess health risks by accounting for species-specific ADME properties. However, modeling PCBs is challenging due to their persistence, bioaccumulation, and structural diversity. While PK models can support risk assessment and interspecies extrapolation, they require accurate data—particularly biological half-lives, which are unavailable for many congeners. This study aims to compile half-life data for individual PCB congeners from the literature in support of future explorations of the use of Quantitative Structure Activity Relationship (QSAR) models to predict half-lives of unstudied congeners using structural features like chlorine substitution patterns, building on prior work. Database curation: The HERO PCBs project page (https://hero.epa.gov/hero/index.cfm/project/page/project_id/384) was searched using terms related to half-life or elimination. Studies retrieved by the literature search were screened to identify studies containing PCB congener half-life data. Select details from each relevant study were entered into the database (e.g., citation information, congener name and number, exposure context, population descriptors, biological matrix, and reported half-life).14 days ago
- Estimating the value of changes in water quality requires the definition of biophysical features that link changes in ecosystems to changes in social systems. Those linking features must be interpretable to people and serve as effective ecological indicators. This work defines a linking feature that is appropriate for capturing existence values in a forthcoming national stated preference survey of Clean Water Act regulations. Further, we modeled and spatially predicted this feature to account for the dependence of survey respondents’ preference on baseline aquatic conditions near them. We outline steps to provide insights on the mechanisms that will aid in forecasting changes in the linking feature in responses to candidate policy options.44 days ago

- In this dataset, we present data on PFAS measured using nontargeted methods in American Healthy Homes Study (AHHS) II residential tap water. Residential drinking water samples were collected as part of the American Healthy Homes Survey (AHHS) II effort by HUD for surveillance of chemicals of concern. Previous analysis was conducted on the collected media to account for lead, but the stability of PFAS enables follow-up analysis even after lead processing. PFAS were analyzed in ~800 water samples using non-targeted analysis by mass spectrometry. Because the methods are nontargeted and thus performed without prior knowledge of the identity of the PFAS in the sample, values are reported as instrument response integrated areas. This dataset is not publicly accessible because: EPA cannot release personally identifiable information regarding living individuals, according to the Privacy Act and the Freedom of Information Act (FOIA). This dataset contains information about human research subjects. Because there is potential to identify individual participants and disclose personal information, either alone or in combination with other datasets, individual level data are not appropriate to post for public access. Restricted access may be granted to authorized persons by contacting the party listed. It can be accessed through the following means: Data presented in this manuscript is available upon reasonable request by contacting the authors, but locations may be censored to protect confidentiality of study participants. Format: EPA’s Office of Research and Development (ORD) was not directly engaged in the collection of information from human subjects.

- Maricopa County partnered with EPA Office of Research and Development to evaluate the utility of sensors to capture wood burning episodes. For this study, PM2.5 sensors were collocated at three air quality monitoring stations within this targeted geographic area. Namely, Durango Complex, West Phoenix, and South Phoenix (designated as DC, WP and SP) for a period of 2 years to better understand sensor performance, comparability with regulatory grade monitors, and to explore drift and changes in performance over time. Approximately 6 months later, phase II began a year+ field study using sensors in a distributed network with FRM/FEM monitors to measure PM2.5 to characterize the impact of local air pollution sources—targeting the wintertime heating season in which wood combustion is the principal air pollutant source of interest; other sensors to be deployed during Phase II include black carbon sensors. The Zenodo link provides raw PM2.5 data collected as part of the P-TAQS study from these PurpleAir sensors and reference instruments deployed at fixed sites at 1-minute time resolution ordered by site and date/time.

- This map shows high-resolution (1 meter) land cover in the EPA Region 3, covering the parts of West Virginia, Virginia, and Pennsylvania outside of the Chesapeake Bay Watershed. It contains the following classes: Water, Tree Canopy, Scrub\Shrub, Low Vegetation, Barren, Impervious Structures, Other Impervious, Impervious Roads, Tree Canopy Over Impervious Structures, Tree Canopy Over Other Impervious, and Tree Canopy Over Impervious Roads. Using object-based image analysis mapping techniques, it was mapped from a combination of remote-sensing imagery and GIS datasets, including LiDAR, multispectral imagery, and thematic layers (e.g., roads, building footprints). Draft output was then manually reviewed and edited to eliminate obvious errors of omission and commission. The classification scheme closely follows a similar mapping effort for the Chesapeake Bay Watershed; together, maps from the two projects cover the entirety of the EPA Region 3 states. One difference between the projects, however, is that tidal wetlands were mapped in the Chesapeake Bay effort, included as the class Emergent Wetlands, but not in the EPA Region 3 zones outside of the watershed. The map is considered current as of 2020 for West Virginia, 2021 for Virginia, and 2022 for Pennsylvania.14 days ago

- This information comes from the dataset README covering the NTA data and associated metadata for this dataset. Dust samples were collected from home vacuum bags and sieved (<150 µm). Internal standard (MPFAC-MXA, Wellington Labs) was spiked , dependent on dust mass, to a concentration of 10 ng/g. Native standards (PFAC-MXA in methanol, Wellington Labs) were dosed into each calibration and QC standard. The next day, 5 ml methanol was added to each sample. Samples were sonicated, centrifuged, and cleaned up. Samples were then blown down using a dry nitrogen gas stream not to dryness; samples were reconstituted to 0.5 ml with methanol as needed. A 100 µl aliquot of sample extract was combined with 300 µl mobile phase A (see below). Sample extracts were analyzed by UHPLC-MS/MS on a Thermo Scientific (Waltham, MA) system consisting of a TriPlus RSH autosampler/injector, Vanquish Horizon UPLC/pump system, and Thermo Orbitrap Fusion tribrid mass spectrometer. Chromatographic separation was performed using a Restek (Bellefonte, PA) Raptor C18 column at 55 °C. A 15-minute reverse-phase gradient was applied consisting of mobile phases A (95:5 v/v deionized water:methanol containing 2.5 mM ammonium acetate) and B (5:95 v/v deionized water:methanol containing 2.5 mM ammonium acetate). Negative-polarity electrospray ionization [ESI (-)] was applied first, with positive-polarity applied afterwards. Mass spectra were collected using a resolving power of 50,000, with preferred-ion data-dependent acquisition (DDA) applied to select molecular features for MS2 fragmentation. Samples were analyzed in a single batch. The full batch was repeated twice with randomized sample order. Separate batches were run for ESI(+) and ESI(-) analysis, for a total of six sample batches. Targeted methanolic calibration standards at concentrations of 1-1000 ng/g Wellington PFAC-MXA PFAS mixture were run at the start and end of the first batch. Method blanks, QC standards, pooled samples, and solvent-only blanks were run every ten samples across all batches. After data collection, chromatograms were processed and peak areas integrated in Thermo Scientific Xcalibur Quan Browser 4.3 for targeted quantitation. For nontargeted identification, chromatograms and associated mass spectra were processed in Thermo Scientific Compound Discoverer 3.3. Features were prioritized for expert identification based on a combination of high maximum abundance, strong match to library spectra, negative mass defect (for PFAS), presence as a member of a likely hologous series (for PFAS and surfactants); and/or presence of diagnostic PFAS-related fragments in their MS2 spectra. Overall, 742 features of interest at confidence 1-3 were identified, as well as 7 confidence-5 features meriting inclusion in the final dataset, and excluding hundreds of features representing false positives/adducts/etc. tentatively identified by Compound Discoverer.14 days ago

- We used exposure data collected for a previous study of DBPs to evaluate how different sources of information impact trihalomethane (THM) exposure estimates, Specifically, we compared gestational exposure estimates to THMs based on water utility monitoring data alone, statistical imputation of daily concentrations to incorporate temporal variability, and personal water consumption and use (bathing and showering). We used Spearman correlation coefficients and ranked kappa statistics to compare exposure classifications. This dataset is not publicly accessible because: EPA cannot release personally identifiable information regarding living individuals, according to the Privacy Act and the Freedom of Information Act (FOIA). This dataset contains information about human research subjects. Because there is potential to identify individual participants and disclose personal information, either alone or in combination with other datasets, individual level data are not appropriate to post for public access. Restricted access may be granted to authorized persons by contacting the party listed. It can be accessed through the following means: Data that CDC collects or holds must be available for data sharing within a year after the data are evaluated for quality and shared with any partners in data collection activity. Because NBDPS data contain PII, NBDPS data are not released publicly. Instead, they are available via a special use agreement. Qualified researchers can be granted access to NBDPS data for analysis through collaboration with one of the Centers for Birth Defects Research and Prevention. The procedure for applying for access to NBDPS data can be found on the NBDPS Public Access Procedures web site: https://www.cdc.gov/ncbddd/birthdefects/nbdps-public-access-procedures.html.
