Effects of spoil groundwater on water-quality in a receiving lake
- Ohio State Univ., Athens, OH (United States)
A groundwater and surf ace-water study was conducted in order to determine the source(s) which are adversely affecting a 35-acre lake in southeastern Ohio. The lake has a pH of 3 and is flanked on the north by about 100 acres of recently reclaimed spoil, and on the south and west by an area of similar size that has not been reclaimed since surface mining ceased over thirty years ago. Inflows into the lake from the north include three major seeps and the outlet of a limestone drain installed early in the recent reclamation. These inflows contribute only about s to 10 percent of the total inflow into the lake but have very poor water-quality, with acidities approaching 1800 mg/L as CaCO{sub 3}. The other major inflows originate to the south and west of the lake and include three streams and Spring U, which account for nearly 70 percent of the total inflow to the lake, but which have lower acidities ranging from -15 to 250 mg/L depending on the time of year. The remaining inflows include groundwater that seeps into the lake. Although the lake receives inflows from other sources, we believe that the groundwater contribution is a significant factor in overall lake-water quality. Coal-seam-elevation data, monitoring-well surveys and estimations from old topographic maps indicate that the dominant groundwater flow is from old underground mines and auger mining north of the site.
