E.I. DuPont De Nemours & Company manufactured explosives on this 570-acre site at the north end of Pompton Lakes, New Jersey from 1902-1994. Land use in the vicinity is primarily residential and commercial, but also includes undeveloped areas, an interstate highway (Route 287) and state-owned forest. Cleanup of the facility is required under a New Jersey Department of Environmental Protection (NJDEP) order, NJDEP ground water permit and an EPA permit.

Waste management practices during the facility’s operation resulted in contamination of surface water, soil and sediment, and ground water both on and off site. Wastes disposed of on site included lead salts, mercury compounds, explosive powders, chlorinated solvents, waste wire drawing solution and detonated blasting caps. Primary contaminants in the soil and sediments are lead and mercury. Ground water contaminants include volatile organic compounds which are potentially harmful contaminants that can cause vapor intrusion to indoor air. Lead and mercury releases have migrated off site resulting in soil contamination at 140 homes near Acid Brook, which were remediated. Contaminated ground water also migrated off site with the potential for vapor intrusion from contaminated ground water impacting off-site residences.

Remedial actions at the site are focused on investigating and cleaning up the area. Much of the soil contamination has been removed and a ground water pump and treat system has been installed. Ground water monitoring is continuing at the site and in the interim DuPont will be installing vapor mitigation systems at residences within the ground water plume and further assess ground water plume/vapor intrusion delineation.
