SITE BACKGROUND

The California Gulch site consists of about 18 square miles in Lake County, Colorado. The area includes the city of Leadville, parts of the Leadville Historic Mining District and a section of the Arkansas River from the confluence of California Gulch downstream to the confluence of Two-Bit Gulch. Former mining operations contributed to metals contamination in surface water, groundwater, soil and sediment. Cleanup is complete at several areas of the site. Operation and maintenance activities at these areas are ongoing. Cleanup of the remaining areas is ongoing.
