The U.S. Geological Survey (USGS) conducted an Abandoned Mine Lands (AML) Initiative during the fiscal years 1997 through 2001 to provide technical assistance in support of Federal Land Management Agency (FLMA) actions to remediate contamination associated with abandoned hard rock mining activities. This initiative was part of a larger strategy by the U.S. Department of the Interior and the U.S. Department of Agriculture to coordinate activities for the cleanup of federal lands affected by AML.
The USGS Abandoned Mine Lands Initiative (AMLI) strategy employed a watershed approach, in which contaminated sites were identified and remediated based on their effect on the water and ecosystem quality of a targeted watershed. The initiative was implemented on a pilot scale in two watersheds, the Boulder River basin in southwestern Montana and the Upper Animas River basin in southwestern Colorado.
While the AMLI project is completed, USGS scientists are still conducting research and monitoring activities. With the 2015 mine wastewater release into Cement Creek, USGS scientists have provided scientific input following the spill and are studying various environmental impacts of the spill.
