FACT SHEET - Former Raritan Arsenal (FUDS), NJ

Formerly Used Defense Sites (FUDS)

Published Jan. 15, 2013

DESCRIPTION: The former Raritan Arsenal occupied approximately 3,200 acres and was bounded by Woodbridge Avenue and the Raritan River between Mill Road and Clearview Avenue in Edison, New Jersey, Congressional District NJ-6.  The Former Raritan Arsenal was used extensively for U.S. Army operations from 1917 to 1963.  Operations included receipt, storage, and maintenance of ammunition shipped from other ordnance facilities or returned from overseas; renovation of ammunition designated for long-term storage; the salvage of outmoded or seriously deteriorated ammunition; ordnance research and development; and shipment and receipt of weapons.  During operations, waste materials, including ordnance, were routinely buried on site as this was the standard method of disposal at that time.  The arsenal was closed in 1963.  Following closure, areas of the site were identified for further study to address the disposal of ordnance and other wastes related to arsenal operations.  This preliminary remediation work resulted in many of the areas being surface cleared or partially decontaminated.  More extensive investigations followed, including work under the Defense Environmental Restoration Program (DERP) for Formerly Used Defense Sites (FUDS) program.


AUTHORIZATION/PROJECT DESCRIPTION:  The former Raritan Arsenal is being investigated under the Defense Environmental Restoration Program (DERP) for Formerly Used Defense Sites (FUDS).  The Superfund Amendments and Reauthorization Act of 1986 authorized that program.  Corps investigations of the former arsenal concluded that conventional, high explosive ordnance and hazardous and toxic waste (HTW) contamination are present. As significant health and safety threats were identified, they have been addressed.
