2015 Gold King Mine waste water spill edit

The waste water in this incident is classic acid mine drainage, which is common around the world where subsurface mining exposes metal sulfide minerals such as pyrite to water and air. The release volume was equivalent to less than 1 hour of Animas River streamflow above Cement Creek (120 ft3/s) on the day of the spill or 11 minutes of streamflow downstream at Durango, Colorado, the next day (600 ft3/s).^[3] Extensive research has been published for the Cement Creek basin and similar watersheds affected by acid mine drainage at Summitville, Colorado, and elsewhere.^[4]

Stream conditions that had been common^[5] in the area 20 years earlier returned temporarily following the spill.

The chemical processes involved in acid mine drainage are common around the world where subsurface mining exposes metal sulfide minerals such as pyrite to water and air.
