The Midnite Mine is an inactive, hardrock uranium mine on the Spokane Indian Reservation, Stevens County, WA. Oxidation of sulfide-containing minerals, primarily pyrite, in the ore body produces large quantities of acidic water. An interception system installed by the mining company limits the discharge of contaminated water from the mine. The Bureau of Indian Affairs and the Bureau of Land Management have been actively involved in planning remediation of the disturbed areas. To assist in remediation, the U.S. Bureau of Mines initiated research to determine water quality and define groundwater flow characteristics. Bureau personnel designed a monitoring network, supervised installation of sampling wells, and collected and analyzed water samples. This Report of Investigations describes interpretation of data collected between December 1989 to April 1992.
