Superfund Site Profile
The Kennecott South Zone includes the Bingham Mining District in the Oquirrh Mountains, about 25 miles southwest of Salt Lake City, Utah. The area includes Bingham Canyon open pit mine, associated waste rock dumps, Copperton Mill and many other historic sites. Mining activities at the site began in the 1860s and continue today. The resulting wastes contain hazardous substances, including heavy metals. Soils and sludge are contaminated, as are surface water and groundwater, which affect wetlands between the site and the shore of Great Salt Lake. Cleanup is ongoing. The site is not listed on the National Priorities List (NPL) but is considered to be an NPL-caliber site and is being addressed through the Superfund Alternative Approach.
