If you haven’t heard yet, on August 7th an abonded mine in Durango, Colorado, spilled 1 million gallons of wastewater into the clean waters of the Animas River.
Contaminants from this mine threaten the water quality for the residents who live downstream from the spill, and so Durango residents were warned to cut back on water use until officials could evaluate the river.
According to the Denver Post, it was actually the EPA (Environmental Protection Agency) that triggered the spill while using heavy machinery to investigate pollutants at another location. They say the wastewater contained zinc, iron, copper and other heavy metals.
