Contamination of surface and ground waters, as a result of mining and mineral processing, represents some of the most complex and wide-spread environmental problems facing the nation today. The U.S. Bureau of Mines Biotechnology Program is developing and demonstrating bioprocesses to control inorganic pollution and restore environments damaged by past mining activities. One of the many current research projects involves investigations of natural remediation mechanisms occurring at Chalk Creak, Colorado. This includes cooperative research with Atlanta University and coordination with the Denver Research Center, Environmental Protection Agency, Colorado State Division of Mineral sand Geology, and U.S. Forest Service to characterize the mine, tunnel drainage, and wetlands at the site. The Biotechnology Program will investigate the natural remediation of mines waters containing high zinc manganese concentrations. Site bacteria, water, and solid samples have been collected to characterize remediation mechanisms occurring within the tunnel. The project goals are to determine the naturally-occurring remediation mechanism(s), maintain and enhance the mechanisms to prevent further site pollution, and apply the remediation mechanisms to other similar areas.
