The Sullivan's Ledge site is a 12-acre disposal area in urban area of New Bedford, Massachusetts. The site is bordered by a country club and marsh area to the north and small businesses to the east and west. The site was operated originally as a granite quarry and includes four 150 feet deep quarry pits. Between the 1930s and 1970s, the quarry and adjacent areas were used for disposal of hazardous materials and other industrial wastes. Site investigations conducted in 1986 and 1988 revealed high concentrations of PCBs in soil and sediment, and VOCs and inorganics in on- and offsite ground and surface water. Surface runoff and ground water from the disposal area discharge into the adjacent stream which drains into the country club golf course and the middle marsh wetlands area.
