Analysis of toxicity of leachates from coal liquefaction wastewater treatment sludge
The disposal requirements for wastewater treatment sludge from coal liquefaction plants will be determined by toxicity tests established by the Environmental Protection Agency (EPA) to enforce the Resource Conservation and Recovery Act (RCRA). Concentrations of eight elements in samples from a noncommercial plant were well below the standards used in the EP (extraction procedure) test of the EPA. Toxicity bioassays with Daphnia magna supported the results of the EP tests. Leachates generated according to the American Society for Testing and Materials extraction procedure (ASTM D-3987) were also tested. Concentrations of RCRA elements were frequently below the minimum detectable concentrations, and no differences in toxicity of the EP and ASTM extracts were evident. 17 references, 3 tables.
