Redevelopment at the Site

The 10-square-mile Tucson International Airport Area (TIAA) Superfund site is located in Tucson, Arizona. The site includes the Tucson International Airport, portions of the Tohono O’odham Indian Reservation, residential areas of Tucson and South Tucson and the Air Force Plant #44 Raytheon Missile Systems Company (AFP44). At least 20 facilities have operated on the site area since 1942, including aircraft and electronics facilities, fire drill training areas and unlined landfills. Industrial use and disposal of wastes began in the 1940s and 1950s. Because of widespread groundwater and soil contamination, EPA added the site to the Superfund program’s National Priorities List (NPL) in 1983. Cleanup includes groundwater treatment at AFP44 since 1987 and at the airport since 1994. Soil treatment is ongoing. Tucson International Airport remains operational. Other activities on the TIAA site include machining, surface preparation, surface coating, metal plating and missile parts assembly.
