Contaminated dredged material is often placed in confined disposal facilities (CDFs) designed and operated to control environmental impacts of the disposed sediment. A CDF is a diked enclosure having structures that retain dredged material solids. When contaminated dredged material is placed in a CDF, contaminants may be mobilized to form leachate that may be transported to the site boundaries by seepage. The purpose of the research presented here is to ...
This report presents the results of verification studies on chemical clarification methods for dredged material disposal developed during the Dredged Material Research Program and provides laboratory procedures and design guidelines for designing treatment systems to clarify the effluent from a dredged material containment area. Guidelines are also presented on operating the systems and estimating the treatment costs. Thirty-five chemicals were screened in laboratory tests to determine which types of polymer ...
