Santa Fe, NM – Eighty years after the first radioactive waste was buried at the Los Alamos National Laboratory (LANL), Lab officials have released plans to “defer” cleanup of one of the older radioactive dumps. Material Disposal Area C (“Area C”) is an 11.8-acre site that was active from 1948 to 1974. It contains metals, hazardous constituents, and radioactively and chemically contaminated materials in six unlined disposal pits and 108 shafts. The total waste and fill in the pits and shafts are estimated at 198,104 cubic meters. Area C also has a serious gas plume of industrial solvents. Given the amount of long-lived plutonium wastes that are likely to be in Area C, leaving it buried 25 feet deep in a landfill rated for only 1,000 years is not acceptable.
On June 18, 2025, the Department of Energy (DOE) sent the New Mexico Environment Department (NMED) a letter outlining its plans to “defer corrective action” (i.e. cleanup) at Area C. It stated that the dump “is associated with active Facility operations and will be deferred from further corrective action under [NMED’s] Consent Order [governing cleanup] until MDA C is no longer associated with active Facility operations.”
