Background—The New Brunswick, New Jersey, Site was remediated under the Formerly Utilized Sites Remedial Action Program (FUSRAP). FUSRAP was established in 1974 to remediate sites where radioactive contamination remained from Manhattan Project and early U.S. Atomic Energy Commission (AEC) operations.

History—From 1948 to 1977, the Manhattan Engineer District and AEC operated the New Brunswick Site as a general nuclear chemistry laboratory.

The site was partially remediated in two phases between 1978 and 1983, including removal of all aboveground structures, contaminated concrete foundations and on-site drain lines, and contaminated soils on the front two-thirds of the property. In 1990, DOE designated the site for additional remediation of residual soil contamination under FUSRAP. DOE remediated localized areas of contamination identified in 1996 and certified that the site complied with applicable cleanup criteria and standards in September 2001. In 2009, at the request of the State regulator, DOE collected additional radiological data on drain lines entering a sanitary sewer in the public right of way. DOE found no indication of above-background radioactivity.

Final Conditions—A deed restriction prevents excavation in an area where soils with elevated arsenic levels are covered by a layer of clean soil. DOE inspects the restricted area every other year and submits a certification of protectiveness to the State regulator and stakeholders. Office of Legacy Management activities also include managing site records and responding to stakeholder inquiries.
