The Environmental Protection Agency said Friday it would continue to monitor a mine that spilled wastewater into the Animas River and added sampling results should be available next week.
Crews with the Bureau of Land Management notified the EPA on Wednesday night the Silver Wing Mine, north of Eureka, was releasing mine wastewater into the Animas River, discoloring the waterway.
The mine is in the Bonita Peak Mining District Superfund, but the EPA has not begun cleanup work there, agency officials said. The Silver Wing Mine historically has discharged wastewater, but the spill is thought to have released more wastewater than normal.
Andrew Mutter, a spokesman for the EPA, said field crews that visited the site Thursday reported the discharge flow rate from the Silver Wing Mine was similar to past flow rates and the water in the Animas River downstream of the Silver Wing was running clear.
