Superfund Site: PICATINNY ARSENAL (USARMY)
ROCKAWAY TOWNSHIP, NJ

Superfund Site Profile


SITE BACKGROUND

The Picatinny Arsenal site covers approximately 5,900 acres in Morris County, New Jersey. Beginning in the mid-1800s, Picatinny manufactured artillery, ammunition, explosives, and other weapons. These past industrial activities and waste disposal practices contaminated surface water, groundwater, soil, sediment, and game fish with hazardous chemicals including heavy metals, organic compounds, and munitions constituents. As part of the site’s cleanup, contaminated soils have been removed or capped, groundwater remedies are in place, and land use controls are used to limit the potential for exposure to hazardous waste. Cleanup activities and monitoring are ongoing, with upcoming efforts to remove soil contamination, address pollution in on-site lakes, and investigate munitions-related contaminants. Today, the facility is an active weapons research and development facility owned by the U.S. Army.
