An NRC committee will conduct an independent evaluation of dredging projects that will look at the expected effectiveness of dredging contaminated sediments at Superfund megasites. The assessment will consider whether EPA's estimated risk reduction benefits are likely to be achieved in the time frame as predicted. Aspects of risk reduction include decreased potential for current and long-term exposure of human and ecological receptors and decreased potential for environmental dispersion of contaminants. The assessment will also consider the potential for short-term increases in risks due to resuspension during dredging.

Sediment Dredging at Superfund Megasites: Assessing the Effectiveness
Consensus Study Report

Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover...
