The Sullivan's Ledge site consists of a 12-acre former quarry site/disposal area and 14.5 acres of downgradient wetlands areas in New Bedford, Bristol County, Massachusetts. The downgradient portion of the site, which is the focus of the Record of Decision (ROD), includes two wetlands areas. From the 1930's to 1970's, the City of New Bedford acquired the property and used the quarry pits and nearby areas for disposal of hazardous materials including electrical transformers and capacitors, fuel oil, volatile liquids, and other industrial wastes. From 1988 to 1990, several EPA investigations identified contamination by PCBs and PAHs in surface and subsurface sediment, soil, and biota; and VOCs and inorganics in ground water. Contamination has resulted in part from contaminated sediment migrating from the disposal area via the Unnamed Stream and deposition in Middle Marsh during stream flooding. The ROD addresses the Middle Marsh as OU2. The primary contaminants of concern affecting the soil, sediment, and surface water are VOCs including toluene; other organics including PAHs, PCBs, pesticides, and phenols; and metals including lead. The selected remedial action for this site is included.
