Superfund Site Profile
The 9,000-acre Carpenter Snow Creek Mining District site is located in the Little Belt Mountains of southern Cascade County, Montana. The site includes mine tailings, waste rock and mine-influenced waters due to many inactive and abandoned mines. EPA has identified about 96 abandoned mines at the site; at least 21 of these are probable sources of contamination. Historic mining operations contaminated soil, groundwater, surface water and sediment with metals and other hazardous chemicals. Investigation and cleanup activities are ongoing.
