Castle Air Force Base
Base Background
Location
5050, Santa Fe Drive, Atwater, California, 95301, United States
Years of Operation
1941-1995
Castle Air Force Base originally opened in 1941 as the Army Air Corps Basic Flying School. It earned its current name in 1948, honoring General Frederick W. Castle who died in a bombing mission during World War II. Aircraft training remained the main mission of the base until it closed in 1995. The Air Force transferred much of the base to Merced County and oversaw environmental cleanup of contaminated soil and groundwater.
Toxic Exposure at Castle Air Force Base
This Californian base has a long history of environmental contamination. Facility operations generated hazardous waste from 1941 until 1977, leading to widespread soil and groundwater contamination. Groundwater contamination was first discovered in 1979, prompting immediate investigative and remediation efforts by the Air Force.
Castle AFB TCE Contamination
Extensive contamination was found to involve multiple toxic substances critical to aircraft maintenance and operations. Trichloroethylene (TCE), a solvent used to remove grease from metal parts, was a primary contaminant. The base also contained significant quantities of 1,2-dichloroethylene, jet fuels, and polychlorinated biphenyls (PCBs). Over 1,000 pounds of TCE and more than 25,000 gallons of fuel contamination were removed from the soil during cleanup operations. Lead-contaminated soils were excavated from the firing range in 1999, the skeet shooting range in 1997, and PCB-contaminated soils were removed in 1998.
Did Castle Air Force Base Store Agent Orange?
There is currently no accepted evidence that Agent Orange was stored at Castle AFB and the VA has not recognized it as an Agent Orange location.
