march air force base

22 CSG/CC

The 7,123-acre March Air Force Base has been used for aircraft maintenance and repair, refueling operations, and training activities since 1918. In 1980, the Installation Restoration Program (IRP) was developed by the Department of Defense to locate and clean-up hazardous waste sites. The Air Force conducted a preliminary investigation of 39 potentially contaminated IRP sites on base which included three fire training areas, seven inactive landfills, underground solvent storage tanks, an engine test cell, and spills. There are now a total of 44 IRP sites on the March Air Force Base. Three zones of groundwater contamination beneath the base were identified and wells on base were shut down in the late 1980's. 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. Approximately 11,600 people obtain drinking water from municipal wells within three miles of the site.
