Sediments in the New Bedford Harbor and Acushnet River Estuary have been contaminated with polychlorinated biphenyl compounds and heavy metals. The high levels of contamination have resulted in the New Bedford Harbor being placed on the National Priorities List of the Nation's worst hazardous waste sites. Efforts are under way to develop and implement remedial actions for protection of the environment under the Federal Superfund Program. This report is an introduction to and an overview of a series of reports describing the results of the EFS. It presents the overall study objectives and scope of work, describes the objectives and scope of the 10 EFS tasks, and presents a brief synopsis of the other 11 reports in the series. The EFS technical approach used field data-collection activities, literature reviews, laboratory (bench-scale) studies, and analytical and numerical modeling techniques to assess engineering feasibility and develop conceptual alternatives for dredging and dredged-material disposal. Technical and engineering issues addressed by the EFS included baseline mapping, geotechnical investigations, hydrodynamics, sediment resuspension and transport, contaminant releases to surface and ground water, dredged material settling properties, dredging equipment and controls, effluent treatment, solidification/stabilization of dredged material, confined-disposal-facility design, contained aquatic-disposal-facility design, and cost estimates for the alternatives evaluated.
