Book Description
Evaluating the environmental consequences of contaminant bioaccumulation resulting from dredged material disposal is a complex technical and regulatory problem. This problem is exacerbated by the high cost of bioaccumulation testing and the lack of explicit guidance on how bioaccumulation data should be interpreted and used within a regulatory program. Bioaccumulation is a measurable phenomenon, rather than an effect. Without specific information about biological effects (e.g., reduced survival, growth, reproduction in animals, cancer risk in humans) resulting from bioaccumulation, it is difficult if not impossible from a regulatory standpoint to objectively determine what level of bioaccumulation constitutes an 'unacceptable adverse effect.' Existing regulatory guidance attempts to overcome this with two approaches, both of which use low aquatic trophic level organisms and a reference-based comparison. In the first approach, the level of bioaccumulation of a specific contaminant is compared with a numerical effect limit, such as a Food and Drug Administration action level or a fish advisory. If the level of the contaminant in the organism exceeds the numerical limit, it is equated to an unacceptable adverse effect. If it does not, or there is no numerical limit, the second approach involves a comparison with animals exposed to a reference sediment. If bioaccumulation in the animals exposed to the dredged material exceeds that of animals exposed to the reference, a number of subjective factors are then evaluated to determine whether or not dredged material disposal will result in an 'unacceptable adverse effect' (U.S. Environmental Protection Agency (USEPA)/U.S. Army Corps of Engineers (USACE) 1991, 1994).

Book Description
Sediment contamination is a widespread environmental problem that can potentially pose a threat to a variety of aquatic ecosystems. The sediment test methods in this manual will be used by The United States Environmental Protection Agency (USEPA) to make decisions under a range of statutory authorities concerning such issues as: dredged material disposal, registration of pesticides and toxic substances, superfound site assessment, and assessment and cleanup of hazardous waste treatment, storage, and disposal facilities. The use of uniform sediment testing procedures by USEPA programs is expected to increase data accuracy and precision, facilitate test replication, increase the comparative value of test results, and ultimately, increase the efficiency of regulatory processes requiring sediment tests.

Book Description
This document is a compendium of scientifically valid and accepted methods that can be used to assess sediment quality and predict ecological impacts...the intent here is to provide the most useful overall measures or predictors of ecological impacts currently in use rather than procedures that may have limited application outside of a particular regulatory framework... parag The information provided in the compendium on the relative strengths and weaknesses of the different assessment methods can provide assistance in selecting the appropriate methods.
