Acid/Pueblo Canyon, New Mexico, Site
FUSRAP Site

Acid/Pueblo Canyon Map

Background—The Acid/Pueblo Canyon 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—The Acid/Pueblo Canyon Site, owned by Los Alamos County, is located in the Pajarito Plateau Region near Los Alamos, New Mexico. Between 1943 and 1964, nuclear weapons activities conducted by the Manhattan Engineer District and AEC resulted in contaminated rock on a cliff face where the effluent from the treatment plant had flowed and contaminated rock, soil, and sediment on the canyon floor.

AEC remediated the contaminated areas in 1966 and 1967. DOE completed additional remediation of the site under FUSRAP in 1982. DOE certified that the site conformed to applicable cleanup criteria in August 1984 and released the affected areas for unrestricted use.

Final Conditions—Office of Legacy Management long term stewardship responsibilities consist of managing FUSRAP site records and responding to stakeholder inquiries.
