Tarutis, W., K. Klemow, & T. Walski. 1994. A SURVEY OF WATER QUALITY IN ACID MINE DRAINAGE STREAMS IN THE WYOMING VALLEY, PENNSYLVANIA. Contributed paper: Pennsylvania Academy of Science meeting. Abstract: Journal of the Pennsylvania Academy of Science 67:200.
The drainages from anthracite coal mines and overburden piles (culm banks) in northeastern Pennsylvania are major sources of metals and acidity in the watershed of the Susquehanna River. A survey of water quality in the acid mine drainage seeps and streams of greater Wilkes-Barre (Wyoming Valley), Pennsylvania was initiated to update existing data and establish a regional chemical database to be used in future studies, The initial survey included analyses of pH, redox potential, specific conductance, total iron, and sulfate; subsequent studies included additional parameters. The drainages examined thus far are moderately (pH approximately equal to 5) to very acidic (pH < 3) and discharge large amounts of iron and sulfate (as high as several tons per year) into local streams, resulting in the formation of ochreous precipitates commonly observed in local streams. The results demonstrate that even after more than thirty years since coal mining ceased, acid mine drainage in the Wyoming Valley is widespread and still a significant source of pollutants.
