Walski, T., M. Curry, & K. Klemow. 1995. IS THE SUSQUEHANNA RIVER A SOURCE OR SINK FOR ACID MINE DRAINAGE IN THE WYOMING VALLEY OF EASTERN PENNSYLVANIA? Contributed paper: Pennsylvania Academy of Science Meeting. Abstract: Journal of the Pennsylvania Academy of Science 68:197.
Acid mine drainage originating from the mine voids under the Wyoming Valley of Luzerne County is a principal contributor to pollution in the Susquehanna River. One approach to reducing the pollutant load would be to prevent water from entering the voids, thereby reducing the outflow. Since many of the mine voids are under the river itself, it is possible to question whether the river is a source of water to those voids. If so, reducing the flow of water into the voids would require altering the riverbed to make it impermeable to water; hardly a practicable alternative. To determine whether the river is indeed a source of water to the underground pool, the river levels were correlated with that of the underground pool in 1992. In all cases, the river level was lower than that of the mine pool levels. Therefore, the river is a net sink for mine water and not a source. Instead, streams entering the valley and infiltration through the soils of the valley are the most likely sources.
