Bayo Canyon Map

 Background—The Bayo Canyon, New Mexico, 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 Bayo Canyon Site, owned by Los Alamos County, is located in the Pajarito Plateau Region near Los Alamos, New Mexico. Los Alamos National Laboratory radiochemistry operations and explosives experiments conducted between 1943 and 1961 contaminated buildings, sewer lines, and soils at this site.

Between 1960 and 1963, AEC demolished site structures, removed surface debris, and excavated contaminated waste disposal facilities. Site ownership was transferred to Los Alamos County in 1967. DOE resurveyed the canyon in 1976 under FUSRAP and identified 1.5-acres with soil underground contaminated by strontium-90. In 1982 DOE placed six monuments inscribed with “Buried radioactive material” around the area. The strontium-90 will have decayed below cleanup criteria by 2142.

 Final Conditions—Office of Legacy Management activities consist of managing site records and responding to stakeholder inquiries.
