One year ago, Environmental Protection Agency contractors inadvertently leached wastewater from an abandoned gold mine into the Colorado’s Animas River — turning it a lovely shade of brown.
It caused a shutdown of the popular recreational river for eight days and flowed as far as Lake Powell, which supplies much of the region’s water for drinking. Two thousand Navajo farmers and ranchers were unable to water or irrigate their crops after the accident, and officials with Navajo Nation declared an emergency in the wake of the accident.
Today, metal-laden water is still contaminating the river at 500 gallons a minute, Colorado Public Radio reports. The only improvement is that the polluted water is now getting filtered at a temporary treatment plant.
The Gold King Mine spill exposed an problem endemic to western U.S. There are 161,000 similar abandoned mines across 12 states, with an estimated 20 percent, or 33,000, polluting groundwater and environment.
