Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective."--Publisher's description 606 $aDredging$xEnvironmental aspects 606 $aDredging spoil 606 $aContaminated sediments$xEnvironmental aspects 606 $aHazardous waste site remediation$zUnited States 615 0$aDredging$xEnvironmental aspects. 615 0$aDredging spoil. 615 0$aContaminated sediments$xEnvironmental aspects. 615 0$aHazardous waste site remediation 712 02$aNational Academies Press (U.S.) 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910778271603321 996 $aSediment dredging at Superfund megasites$93711318 997 $aUNINA
