Clean Up the Land
N3B remediates sites across LANL where waste was historically spilled or disposed. Sites entail contaminated soil and debris, along with old landfills. N3B is also decontaminating and demolishing facilities used in LANL’s early Cold War-era plutonium processing and radiological liquid waste treatment operations.
Material Disposal Areas
Remediate old landfills, known as Material Disposal Areas, where contaminated material from past LANL operations was disposed.
Middle DP Road
N3B responded to legacy LANL contamination found on Los Alamos County-owned land by investigating, excavating and shipping contaminated soil and debris off-site in preparation of safe residential use.
Technical Area 21
Decontaminate and demolish decommissioned LANL buildings at TA-21, next to Los Alamos’ industrial area, to make the land available for beneficial use.
Aggregate Areas
Investigate, excavate and ship off-site for disposal contaminated soil and debris from LANL’s legacy operations.
