On Aug. 5, 2015, contractors for the Environmental Protection Agency accidentally released 3 million gallons of contaminated mine wastewater into Cement Creek, a tributary of the Animas River. The event triggered a controversial effort to seek Superfund cleanup for the Silverton area. That decision hangs in the balance.

Proposed Bonita Peak Mining District Site

Environmental Protection Agency documents show the proposed Superfund site in Silverton includes 48 mines — 26 that drain into the Upper Animas River, seven that drain into Mineral Creek and 15 that drain into Cement Creek. The site will be called Bonita Peak Mining District if it receives Superfund designation to clean up contamination.
