Gold King Mine release (2015): USGS water-quality data and activities
On August 5, 2015, U.S. EPA was conducting an investigation of the Gold King Mine near Silverton, Colorado. While excavating as part of the investigation, water began leaking from the mine tunnel, and about three million gallons of water and sediment were released into Cement Creek, a tributary of the Animas River. The USGS provided pre- and post-release water-quality and streamflow data from...
Aqueous Crystal Growth and Dissolution Kinetics of Calcium Carbonate Minerals at the Amarigosa Desert Research Site, Nevada
The USGS studies calcium carbonate mineral reactions in soils at the Amarigosa Desert Research Site (ADRS) near Beatty, Nevada, in order to better understand carbon dioxide transport to and from the soil surface, as well as sequestration of toxic elements in the soil.
Aqueous Crystal Growth and Dissolution Kinetics of Earth Surface Materials
Although calcium carbonate reaction kinetics has important application in several areas of Earth Science, the mechanism of natural organic matter mediation of carbonate minerals growth and dissolution rates remains largely unknown. This project uses multiple approaches to study calcium carbonate formation and dissolution rates in surface water and groundwater systems.
