SITE BACKGROUND

The Bonita Peak Mining District site consists of 48 historic mines or mining-related sources where ongoing releases of metal-laden water and sediments are occurring within the Mineral Creek, Cement Creek and Upper Animas River drainages in San Juan County, Colorado. Historic mining operations have contaminated soil, groundwater and surface water with heavy metals. A remedial investigation to determine the nature and extent of contamination is underway.
