Three million gallons of bright orange wastewater has spilled from an abandoned mine in Colorado, after Environmental Protection Agency efforts to contain the mine’s toxic water went awry last week. According to the EPA’s onsite coordinator, a team was working to “investigate and address contamination” at a nearby mine when they unexpectedly triggered the spill from the Gold King Mine, which is still pumping 500 gallons of contaminated water per minute into the Animas River, near Silverton, Colorado.
