Photos Related to Gold King Mine Response
These treatment ponds were built at mines close to the Gold King Mine in Colorado. When water leaves the mines, these ponds slow it down and allow us to adjust the pH and let contaminants settle to the bottom.
As part of our Gold King Mine response, we’ve built diversion channels to direct water flowing out of nearby mines into settlement ponds where we treat it before it enters the creek.
As part of our ongoing response, workers are almost finished stabilizing the road to ensure crews and equipment can access the Gold King Mine.

As water exits the mine, it flows into a system of four treatment ponds. The treatment ponds provide retention time to allow the pH to adjust. Here, lime is added to a settling pond to assist in the pH adjustment of the water prior to discharge to Cement Creek on Aug 14, 2015. (Credit: Eric Vance/EPA)
