Abstract
Since the Mines Development, Inc., uranium mill located at Edgemont, South Dakota, began commercial operation in 1956, the resultant impact of waste management practices on environmental radiation levels has been the subject of several State and Federal studies. During the latter part of July, 1957, an intensive in-plant study was conducted to characterize the mill process and liquid effluents. Water quality studies conducted during September, 1966, and July, 1971, showed that process and waste liquors were being lost by seepage from mill ponds and entering surface waters - Cottonwood Creek and the Cheyenne River. Soil and bottom sediment samples collected during the 1971 study confirmed the loss of unstabilized sand tailings to the water environment by wind and water erosion.
