The Ohio Department of Natural Resources, Division of Reclamation, plans widespread reclamation of abandoned coal mines in the Raccoon Creek basin in southeastern Ohio. Throughout Raccoon Creek basin, chemical, biological, and suspended-sediment data were collected from July 1984 through September 1986.
Chemical and biological data collected at 17 sites indicate that the East Branch, Brushy Creek, Hewett Fork, and Little Raccoon Creek subbasins, including Flint Run, are affected by drainage from abandoned coal mines.
In these basins, median pH values ranged from 2.6 to 5.1, median acidity values ranged from 20 to 1,040 mg/L (milligrams per liter) as CaCo3, and median alkalinity values ranged from 0 to 4 mg/L as CaCo3. Biological data indicate that these basins do not support diverse populations because of degraded water systems.
Suspended-sediment yields of 70.7 tons per square mile per year at the headwaters of Raccoon Creek and 54.5 tons per square mile per year near the month of Raccoon Creek indicate that cumulative sedimentation from erosion of abandoned-mine lands is not excessive in the basin.
