The Expert Query Tool is a web-based reporting tool using the EPA’s WATERS database.There are just three steps to using Expert Query:1. View Selection – Choose what type of information you want from the database.2. Data Element Selection – Choose specific data elements, which will appear as columns in the report, from the database.3. Entering Search Criteria – Refine the data to be displayed and arrange how it will appear in the report.Data can be output from Expert Query in two ways: as HTML (displayed in the user’s web browser) or as a file (comma– or tab-delimited). Files downloaded to the user’s PC can then be imported into a spreadsheet program such as Excel or a database such as Access and manipulated further.
