Superfund Site: MARCH AIR FORCE BASE, RIVERSIDE, CA
Superfund Site Profile
The 7,123-acre March Air Force Base (AFB) has been used for aircraft maintenance and repair, refueling operations, and training activities since 1918. Facility operations contaminated groundwater with hazardous chemicals. Three zones of groundwater contamination beneath the base were identified and wells on base were shut down in the late 1980s. Groundwater contamination has migrated to wells located off base. However, a groundwater containment system has been installed to prevent off-site groundwater migration. These wells are no longer in use. The site’s long-term cleanup is ongoing.
