Abstract : The Clean Water Act in the United States requires that the environmental evaluation of dredged material prior to discharge or impacting the waters of he United States include the effects of disposal on concentrations of contaminants through biological processes. This results in a need for Corps of Engineers districts to be able to predict the contamination of animals that may be associated with potential disposal alternatives: open-water disposal, upland disposal, and wetland creation. The following is a summary of the results of bioassay procedures using the earthworm Eisenia foetida to evaluate the potential contaminant mobility into soil-dwelling animals. These tests were derived from proposed Organization for European Common Development (OECD) and European Economics Commission (EEC) test procedures (evaluating the effects of new chemicals) and modified to consider accumulation and sublethal effects rather than toxicity. pg1 &2.
