mountain home air force base

HWY 67, 10 MI W OF CY

Mountain Home Air Force Base (AFB), established in 1943, is located on approximately nine square miles of land on a plateau southwest of Mountain Home, Idaho. The base has been under the control of the Tactical Air Command since 1965. Hazardous materials have been used by the base for such activities as aircraft maintenance and industrial operations. As a result, hazardous wastes have been generated from operations at Mountain Home AFB. Base wastes were historically disposed of by several methods, including landfilling of solid wastes, discharge of liquid wastes to sanitary sewers, and the use of waste oil in fire training exercises and road oiling. Approximately 30 areas were investigated at the base, including two abandoned landfills, several abandoned fire training areas, several industrial operation areas, and an entomology shop, where pesticides had been rinsed from application equipment. Wastes disposed of or spilled at these locations included petroleum, waste oils, solvents, and pesticides. Wells within three miles of the base irrigate agricultural land and supply drinking water to approximately 14,000 people. On-base water supply wells are the sole source of drinking water for base residents and workers. Site Responsibility: This site is being addressed through federal actions.
