Pilot Study of Dredging and Disposal Alternatives for the New Bedford Harbor, Massachusetts, Superfund Site
Bottom sediments in New Bedford Harbor are contaminated with polychlorinated biphenyls (PCB) and heavy metals to the extent that the site is considered one of the Nation's worst hazardous waste sites and is being studied by the US Environmental Protection Agency (EPA) under the Federal Superfund program. At the request of EPA, the Corps of Engineers has evaluated the feasibility of dredging and disposal alternatives for the upper estuary of New Bedford, an area where PCB concentrations in the percent levels have been detected in the sediments. Between May 1988 and February 1989 a pilot study was performed as part of this effort. This study involved the evaluation of three hydraulic pipeline dredges with the contaminated sediments being placed in a confined disposal facility and a contained aquatic disposal cell. This paper provides a comprehensive discussion of our approach and the results of this $6.5 million effort. The study provided for a site-specific technical evaluation of the methods used which has allowed the Corps of Engineers to make recommendations to EPA which will be critical in their final evaluation of remedial alternatives for the site.
