EPA says it released 3 million tons of contaminated water into river


That's not how the Animas River should look.

No, this is how the Animas River should look.


But then, as the post title says, the EPA released 3 million tons of contaminated water in the Animas River...accidentally, at least.

Another article, this by the Washington Post, does a nice job explaining just what was happening when the accident happened...
When underground water runs through a mine, it picks up traces of the minerals that are buried there, explains Colorado Public Radio station KUNC. When it mixes with mineral pyrite, it reacts with air to form sulfuric acid and dissolved iron. It also picks up other heavy metals, like copper and lead, as well as any of the chemicals that miners have been using to extract the resources. By the time it trickles out of the mountain and into nearby waterways, it’s an acidic, often-toxic brew.

...

The Animas River Stakeholders Group that was set up to deal with the issue after the mines were closed, which includes Sunnyside Gold Corp., didn’t have the estimated $12 million to $15 million it would take to treat the contaminated runoff. And for years, Silverton residents resisted EPA involvement out of fear that the “Superfund” label given to the nation’s worst hazardous waste sites would jeopardize the tourism industry — the only source of income that could replace the vanished mines. A few even hoped that the mines would reopen one day.

Meanwhile supporters of EPA intervention accused Sunnyside of stonewalling the cleanup attempt to avoid liability.

The two sides reached an agreement of sorts this year. The mines would not be designated a Superfund site, and the EPA would provide $1.5 billion to plug the problematic Red and Bonita mine, where polluted water drained at a rate of 500 gallons per minute, according to the Durango Herald.
But water has a habit of finding its way downhill, and plugging one mine often means it simply leaks from others, so the agency had to excavate and stabilize the Gold King mine upstream.
That’s what they were up to on Aug. 5, when the loose material holding the mine together finally gave way. The water that had accumulated in the mine’s long-abandoned tunnels went tumbling into Cement Creek.

“It was known that there was a pool of water back in the mine, and EPA had a plan to remove that water and treat it, you know, slowly,” Peter Butler, who serves as a co-coordinator of the stakeholders group, told KUNC. “But things didn’t go quite the way they planned and there was a lot more water in there than they thought, and it just kind of burst out of the mine.”
And there you go..."it just kind of burst out of the mine."

I've written about the remnants of mining before and was lucky enough to see how it's dealt with at Berkeley Pit in Butte, Montana, particularly in the Silver Bow Creek area.

In the long run the scars left by our mining sites are going to take a very long time to heal, but it's tough to ever look at not mining because we need what's in those hills.

That being said, often times it's even tougher to look at the consequences of our mining.
