Water Quality in an Idaho Stream Degraded by Acid Mines Waters

摘要

The report discusses studies made from 1967 through 1977 that show seepage from the no longer operating Blackbird Mine in east central Idaho has resulted in acidic waters high in sediment and heavy metals. It suggests high concentrations of cobalt, copper, iron, manganese, lead, and zinc in the Panther Creek drainage are the probable cause of diminished insect and fish populations in the area.
