EPA SUMMARY   


At the Bonita Peak Mining District, EPA works with state, local, and other federal officials to implement cleanups. The Bonita Peak Mining District site includes 48 historic mines or mining-related sources where ongoing releases of water and sediments containing metals occur at historic mining source areas. The mining source areas directly impact Mineral Creek, Cement Creek and Upper Animas River drainages in San Juan County, Colorado. Some metals contamination migrates into the Animas River.  

To date, EPA has conducted site wide investigations and carried out interim and emergency actions. EPA’s goal is to reduce immediate risks, stabilize mine waste, and treat ongoing acid-mine drainage. Expected results include sustained reductions in contamination and protective final remedies for major source areas.
