One example: Some years ago, on a visit to Missoula, Montana, I visited the largest Superfund site in the western United States and viewed a dam that was holding back vast quantities of mine-waste metals in sediments that, if loosed, would poison the Clark Fork River – you know, the River Runs Through It.Ĭolorado alone has 14,000 abandoned mines that are leaking waste into water sources, according to the Denver Post – and that figure used to be closer to 23,000 before a long, expensive series of cleanup efforts. The gift that keeps on giving.Īccording to an AP piece that appeared in the Strib on Monday, there are 55,000 abandoned mines in the west, and “40 percent of the headwaters of Western waterways have been contaminated from mine runoff.” Ostrander will need a while, I’m guessing, to live down his choosing to describe the Silverton spill as “just something that happens” from time to time.īut let there be no doubt that the conditions EPA was trying to address at Gold King are as common as cottonwoods across the mining districts of the American West, the permanent legacy of precious-metals production. Environmental Protection Agency spokesman, quoted Monday in a Fox News report. “We typically respond to emergencies, we don’t cause them, but this is just something that happens when we are dealing with mines sometimes.” − David Ostrander, a U.S. Who can possibly guarantee that this could never happen here? Leaking mines all over So as you listen to the reports from Four Corners tracking Gold King’s heavy metals down the Animas, the San Juan and the Colorado as the contamination heads for Lake Powell and beyond, you might keep your eye on the systems and not just the sludge, and keep asking yourself: What happens when the retention setup goes suddenly, disastrously, to pieces? And as those stomach-turning photos from the Animas River remind us, the bigger question yet is: The question yet to be answered for the northern Minnesota mines is how thoroughly their wastes can be managed with containment, treatment and controlled discharge.
