On August 5, 2015, the EPA was conducting an investigation of the Gold King Mine in Silverton, Colorado. The intent of the investigation was to assess the on-going water releases from the mine and to treat mine water, and to assess the feasibility of further mine remediation.
The plan was to excavate the loose material that had collapsed into the cave entry back to the timbering. During the excavation, the loose material gave way, opening the adit (mine tunnel) and spilling the water stored behind the collapsed material into Cement Creek, a tributary of the Animas River.
The SUN News team visited Durango, Colorado, and spoke to the EPA about the circumstances of the release and what’s involved in the cleanup.
