Characterization & Cleanup

Through comprehensive analyses and studies, the Department of Energy has mapped where the contamination is located and is close to finalizing the blueprint for cleaning up the site.

Multiple rounds of sampling by a number of independent agencies have all concluded that there is no offsite threat to human health from DOE’s former operations in Area IV. Extensive assessments have also ruled out any potential pathways for contamination to leave the site.

Soil

DOE and the California Department of Toxic Substances Control (DTSC) have been in the field working on the chemical co-located sampling effort with Environmental Protection Agency (EPA).

Groundwater
