Abstract
The California Gulch site is located in Lake County, Colorado, approximately 100 miles southwest of Denver. The study area for the first remedial action encompasses an 11.5 sq m watershed, which includes the city of Leadville, that drains along California Gulch to the Arkansas River. Between 1859 and 1986, the area was extensively mined for gold, lead, silver, copper, zinc and manganese. Because of these mining operations, the Yak Tunnel was constructed to dewater mines and facilitate mineral exploration and development. Studies indicate that the Yak Tunnel discharges a combined total of 210 tons per year of cadmium, lead, copper, manganese, iron, and zinc into California Gulch, which drains into the Arkansas River. Both California Gulch and the Arkansas River are used by the public for recreation, and the Arkansas River is heavily used for irrigation, livestock watering, public water supply and fisheries as well. Primary contaminants of concern affecting the surface water, sediments, and ground water are cadmium, copper, lead and zinc.
