Horseshoe Road Superfund Site

History & Location

Located on approximately 12 acres near the Raritan River, the Horseshoe Road sites include the Sayreville Pesticide Dump; the former Atlantic Development Corporation Facility; and the Horseshoe Road Drum Dump Facility. For over 30 years, manufacturing operations at these sites involved inadequate waste handling practices, which resulted in dumping waste materials and subsequent site-wide contamination. In 1981, after a fire erupted at the Horseshoe Road Drum Disposal Area, exposed drums were recorded to contain chemical wastes. In 1995, the United States Environmental Protection Agency (USEPA) added the site to the Superfund National Priorities List. To remediate these contaminated sites, Sevenson was awarded this phase of work based on a competitive proposal. The RFP was issued to contract holders of USEPA Region 2’s Long Term Response Action MATOC through the U.S. Army Corps of Engineers, Kansas City District.
