Mine Waste Spill Rivers
FILE--In this Aug. 14, 2015 file photo, an Environmental Protection Agency contractor keeps a bag of lime on hand to correct the PH of mine wastewater flowing into a series of sediment retention ponds, part of danger mitigation in the aftermath of the blowout at the site of the Gold King Mine, outside Silverton, Colo. EPA contractors released more than 3 million gallons of contaminated water Aug. 5 while working at an inactive mine site near Silverton. States and Indian tribes said on Thursday, March 24, 2016, that they are getting ready in case runoff from melting snow stirs up potentially toxic metals in two rivers after a massive spill from a Colorado mine last August.
