DOWNLOAD EBOOKThis document is intended to serve as a consistent "roadmap" for U.S. Army Corps of Engineers and U.S. Environmental Protection Agency personnel in evaluating the environmental acceptability of dredged amterial management alternatives. Specifically, its major objectives are to provide: A general technical framwork for evaluating the environmental acceptability of dredged material management, alternatives (open-water disposal, confined (diked) disposal, and beneficial uses). Additional technical guidance to augment present implementation and testing manuals for addressing the environmental acceptability of available management options for the discharge of dredged material in both ope water and confined sites. Enhanced consistency and coordination in USAC/EPA decision making in accordance with Federal environmantl statutes regulating dredged material management.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKIn this text, drawn from presentations and discussion at a May 2005 NATO Advanced Research Workshop, current approaches to the assessment and remediation of contaminated sediments are discussed with emphasis on in-situ management. The text addresses physical, chemical and biological approaches for the assessment and remediation of sediments. The development of regulatory and strategic approaches is discussed with emphasis on the potential for biological remediation in the management of contaminated sediments.

DOWNLOAD EBOOKSome 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 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.

Up to then it was common practise to dispose dredged material at sea or use it to raise the land or as fertilizer on land. A new approach was to store contaminated dredged material in confined disposal facilities (CDFs). These CDFs are only meant for dredged material that is heavily contaminated and cannot be relocated into the water system or used for engineering or environmental purposes. Much effort was devoted to the design of CDFs and to the assessment and management of environmental risks. Despite the fact that stricter environmental pollution controls meant that sediments in rivers and harbours became less contaminated and options for use of dredged material became more available, there still is the need for more storage capacity for contaminated dredged material arising from certain capital, environmental remediation and sometimes maintenance dredging projects. It is especially difficult to decrease the influence of diffuse sources on contamination levels of sediments."--Introduction.
