Former Raritan Arsenal

Public Meeting and Public Comment Period
Proposed Plans
Areas 6, 6A, 6B and Dredge Spoil Area 1
Dredge Spoil Area 5
Former Raritan Arsenal


The U.S. Army Corps of Engineers (USACE) has conducted investigations of munitions storage and handling at Areas 6/6A/6B and Dredge Spoil Area (DSA) 1, and DSA 5 of the Former Raritan Arsenal Formerly Used Defense Site. These areas are located in the Township of Edison, Woodbridge Township and the Borough of Sayreville.

‒ Areas 6/6A/6B, DSA 1 and the associated surrounding areas encompass approximately 236 acres in the Township of Edison and Woodbridge Township along the east side of the Former Raritan Arsenal. Areas 6A and 6B, which are mostly undeveloped wetlands along the Raritan River, were initially investigated because they were used as burning grounds for various ammunition components until the Arsenal was closed 1963. Areas 6 and DSA 1 were investigated because they were filled with material dredged from the Raritan River, including portions of the river near the Arsenal’s former dock, which may have contained munitions items. Several removal actions have been completed to identify and remove munition items.

‒ DSA 5 comprises approximately 228 acres of land on the south shoreline of the Raritan River in the Borough of Sayreville, directly across and outside of the southeastern boundary of the Former Raritan Arsenal. The area is underlain by dredge spoils that were removed from the Raritan River and deposited during historical dredging operations. DSA 5 is mostly undeveloped wetland, with the exception of the south-central margin, which contains roads and residential housing units. A removal action was completed in 1993.

Investigations have been conducted to determine whether munitions and explosives of concern (MEC) or other Department of Defense (DOD) related constituents are present in these areas. No evidence of an explosive hazard and no unacceptable risks associated with potential exposures to DOD-related constituents were identified; therefore, no further action is proposed.

Public Comment on Proposed Plan Documents

The Proposed Plan documents provide a review of these investigations and summarizes the USACE rationale for recommending no further action at Areas 6/6A/6B and DSA 1, and DSA 5. The Proposed Plans are available for review below, or in hard copy at the information repositories in the USACE New York District office located at 2890 Woodbridge Avenue, Edison, NJ and the USACE New York District Office located at 26 Federal Plaza, New York, NY.

Written comments on the Proposed Plans should be postmarked by August 7, 2021 and mailed to: U.S. Army Corps of Engineers, Attn: Amanda Regan, 2890 Woodbridge Avenue, Edison, NJ 08837 or by email to
