ABSTRACT: Samples were collected from the drainages of inactive deep coal mine sites located in eight states. Drainage quality was found to be highly variable, with a majority of sites exceeding federal effluent quality guidelines. Concentrations of trace metals including cadmium, mercury, zinc, and nickel were low. The presence of overburden calcareous material was shown to affect drainage quality. A consistent pattern of pH‐acidity response was found to exist for the mine sites monitored. An empirical formula was developed to characterize this response.
