The U.S. Geological Survey has completed an environmental study of historical mining in the Animas River watershed upstream of the town of Silverton, southwestern Colorado, using the watershed approach. Results of the study are being used by State and Federal agencies and by the local watershed stakeholders group to plan and implement cleanup. The watershed approach is based on the premise that contaminated sites that have the most profound effect on water and ecosystem quality within a watershed can be identified, characterized, and ranked for cleanup. The process helps land managers evaluate risk and focus remediation efforts on these sites.
