RAINFALL EFFECTS ON WATER LEVELS AND COMPARISON OF WATER CHEMISTRY IN TWO DRIFT COAL MINES AND MINE DISCHARGES ON AN ABANDONED MINE SITE IN ARMSTRONG COUNTY, PA

| Zusammenfassung: | The Carpentertown Coal and Coke Company operated the Mahoning Creek 1 and 2 drift mines for 17 years, closing in December 1987. The company continued to operate a coal cleaning plant and coal refuse disposal site, declaring bankruptcy in June, 1989. In order to determine if there was a connection between the two mines and if they contributed to the eight acidic seeps that developed on the site and an additional seep that developed along the 352m contour on an abandoned strip along Bullock Creek between the mines, the seeps and mine pools were monitored monthly for 36 months. Water elevation in both mine pools was significantly correlated with precipitation and the mean water elevation in both mines being 14m below the Bullock Seep. Total acidity was <0.2 mg/l in both mine pools, but there were significant differences in other chemical parameters between the two mine pools and between the mine pools and different mine seeps. Based on these differences in water chemistry and water elevations of the mine pools, it was concluded that the mine pools were not connected and that their contribution to the water chemistry of the seeps that developed after mine closure was minimal, if it existed at all. |
