Emergency Response to August 2015 Release from Gold King Mine
On August 5, 2015, EPA was conducting an investigation of the Gold King Mine near Silverton, Colorado, to:
- assess the on-going water releases from the mine,
- treat mine water, and
- assess the feasibility of further mine remediation.
While excavating above the old adit, pressurized water began leaking above the mine tunnel, spilling about three million gallons of water stored behind the collapsed material into Cement Creek, a tributary of the Animas River.
EPA takes responsibility for the Gold King Mine release and is committed to continue working hand-in-hand with the impacted local governments, states and tribes.
