The overall objective f the Fossil Energy Technology Water Sampling and Characterization Program is to develop the data base needed to evaluate the potential hazards associated with disposal of fossil energy wastes. The data base is presently incomplete, articulacy with respect to potentially hazardous organic constituents. The purpose of this investigation is to provide analytical information whose validity and precision are established, and to develop and apply uniform analytical methods for analysis of organic compounds in aqueous lactates from fossil energy solid wastes.
