Superfund Site Profile
The 4,043-acre Williams Air Force Base site is located in Chandler, Arizona. The base was commissioned as a flight training school in 1941. Up to 12 million gallons of jet fuel contaminated an aquifer considered by the State of Arizona to be a protected drinking water source. Discharges and disposal at the site have resulted in soil and groundwater contamination. Cleanup, operation and maintenance activities and monitoring are ongoing. The most widespread and complex remaining cleanup remedy remains to be implemented. The Air Force has transferred over 3,800 acres for reuse.
