USGS Scientists Study Effects of Gold King Mine Release

Photograph showing natural iron-rich acidic spring flowing into Cement Creek near Silverton, Colorado.On August 5 2015, while investigating the Gold King Mine in southwestern Colorado, the U.S Environmental Protection Agency accidentally triggered the release of approximately three million gallons of acidic, metal-rich mine wastewater from the Gold King Mine into Cement Creek, a tributary of the Animas River. The Animas River flows south into the San Juan River, which is a tributary to the Colorado River.

Water-Quality Summaries for Several Major River Basins in Colorado

Summaries of water-quality monitoring data are now available for several major river basins in Colorado. For each basin, current data from a network of sites are compared to previously collected data and instream standards. Lowess curves are provided on plots for selected constituents where a sufficient period of record and limited censored data are available.
