The 2015 Gold King Mine waste water spill is a 2015 environmental disaster at the Gold King Mine near Silverton, Colorado. On August 5, 2015, EPA personnel along with workers for Environmental Restoration LLC (a Fenton, Missouri, company under EPA contract to mitigate pollutants from the closed mine) caused the release of toxic wastewater when attempting to add a tap to the tailing pond for the mine. The maintenance was necessary because local jurisdictions had previously refused Superfund money to fully remediate the regions' derelict mines due to a fear of lost tourism. After the spill, Silverton Board of Trustees and the San Juan County Commission approved a joint resolution seeking Superfund money.
