To undertake a marine ecological risk assessment at the Naval Construction Battalion Center (NCBC) Davisville, Rhode Island to determine the effect of hazardous waste disposal on Allen Harbor and Narragansett Bay. Allen Harbor, located in Narragansett Bay at NCBC Davisville, was closed to shellfishing by the Rhode Island Department of Environmental Management because of suspected hazardous waste contamination from a landfill and disposal area adjacent to the harbor. NCBC Davisville was added to the National Priority List in November 1989. Between 1946 and 1972, the 15-acre landfill received a wide variety of wastes, including sewage sludge, solvents, paints, chromic acid, PCB-contaminated waste oils, preservatives, blasting grit, and other municipal and industrial wastes generated at NCBC Davisville and at the Naval Air Station Quonset Point. Another site, also adjacent to Allen Harbor on Calf Pasture Point, was used for disposal of calcium hypochlorite decontaminating solution and chlorides.
