woodbrook road dump


The Woodbrook Road Dump site (a.k.a. Dismal Swamp) is an inactive, dumping area located in South Plainfield, New Jersey. The site is located on two properties north of Woodbrook Road identified as Block 388, Lots 1 and 26 in Middlesex County. The site, totaling approximately 70 acres in size, is heavily wooded and undeveloped, and is bordered by the Bound Brook and is within the wetlands of the Dismal Swamp. There are currently no physical structures on the Site. A house was built on the on Block 388, Lot 26 in the 1940s, was occupied until approximately 2002 and demolished in 2005.The two properties were operated as dumps by previous owners during the 1940s and 1950s, accepting household and industrial wastes until shut down by the State of New Jersey in 1958. The current owner of the properties, Texas Eastern Transmission Corporation (TETCO), acquired the properties in 1972. Partially buried, leaking electrical capacitors were discovered in September 1999. After completion of a removal action to address the capacitors, a soil investigation revealed soils and sediments contaminated with high levels of polychlorinated biphenyls (PCBs). The Site is transected by the northwest-flowing Bound Brook, which forms the boundary between Lot 1 on the east and Lot 26 on the west. Bound Brook flows into central South Plainfield and ultimately discharges to Green Brook and the Raritan River. Three tributaries (referred to as Main Tributary, Secondary Tributary and Railroad Tributary) and a body of standing water (referred to as Western Pond) also bound portions of the Site and discharge to Bound Brook. PCB contamination was discovered in two dumping areas: the Eastern Dump and the Western Dump. The Eastern Dump (on Lot 1) is located on the east side of the Bound Brook and contains primarily municipal waste, i.e., glass, scrap metal and plastic, and no known capacitors. The Eastern Dump contains approximately 65,000 cubic yards (yd3) of debris over an area of 13 acres. The Western Dump (on Lot 26 and a small portion of Lot 1.01, which is owned by South Plainfield) is located on the west side of the Site and includes Disposal Areas 1 and 2 where capacitors and capacitor parts were discovered. The Western Dump contains approximately 122,000 yd3 of debris over a footprint of approximately 19 acres. The remaining acreage consists of the perimeter surrounding the two dumps and the Panhandle, located to the north of the Eastern Dump. Site Responsibility: The remedial investigation and feasibility study for the site were addressed through federal and potential responsible parties’ actions. The current Remedial Design is being addressed through federal actions.
