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.
