Superfund Site Profile
The Picatinny Arsenal site is located in Morris County, New Jersey. The Arsenal has a long history of manufacturing explosives, beginning in the mid-1800s. Past industrial activities and waste disposal practices contaminated surface water and groundwater with hazardous chemicals. As part of the site’s cleanup, contaminated soils have been removed or capped, groundwater remedies are in place, and land use controls have been put in place, limiting the potential for exposure to hazardous wastes. Cleanup activities and monitoring are ongoing. Today, the facility is an active weapons research and development facility owned by the U.S. Army.
