Abstract
Three sample areas are analyzed to determine potential pollution impacts of surface mining on the shallow ground water systems. Areas analyzed were in the southeastern portion of North Dakota, the Gillette area of Wyoming and the Decker-Birney area of Montana. They were selected as representative of areas where accelerated coal mining is likely to occur. The analyses indicates there will be: (1) Localized disruptions of aquifers; (2) drainage of adjoining clinker beds; (3) drainage of aquifers in immediate vicinity of mines; (4) underlying aquifers will be little affected; (5) possible increase in nitrate and sulphate concentrations in mine waters; and most importantly (6) contamination of the water resource by dissolved material leached from strip-mining spoils. All problems except pollution of ground water from spoils should be minimal after replacement of spoils and rehabilitation. Ground water pollution could be long term.
