Superfund Site Profile
The Ordnance Products Inc. site occupies approximately 95 acres in North East, Maryland. The site was historically occupied by a ordnance component manufacturing facility from 1960 to 1972. The plant produced, stored, and packaged grenade fuses, detonators and related devices for the U.S. military. Waste from the manufacturing process was either buried onsite in open pits or discharged to five unlined surface impoundments. After manufacturing work ended in 1972, waste material remained in the surface impoundments or was buried in pits and trenches throughout the site. These wastes included drums of solvents and acids, detonators, and grenade fuses.
On-site groundwater and soil are contaminated with chlorinated volatile organic compounds (VOCs) and perchlorate, a chemical used in explosives manufacturing. Residential water supply wells located near the site are also impacted by site-related compounds. EPA maintains treatment systems on impacted wells to provide safe drinking water to residents and samples impacted wells on a quarterly basis.
