Water quality of large discharges from mines in the anthracite region of eastern Pennsylvania Water quality of large discharges from mines in the anthracite region of eastern Pennsylvania
In 1991, 99 of the 102 coal mines in the anthracite coal fields of Pennsylvania that discharged 1.0 cubic foot per second or more when water-quality samples were collected in 1975 were revisited. Water was not discharging from 15 of these 99 mines in 1991. Discharge, water temperature, specific conductance, pH, dissolved oxygen, sulfate, iron, manganese, alkalinity, and acidity were...

Quality of ground water at selected sites in the upper Mahoning Creek Basin, Pennsylvania Quality of ground water at selected sites in the upper Mahoning Creek Basin, Pennsylvania
The ground-water quality of the upper Mahoning Creek Basin is largely unknown. Human activities in the basin have altered much of the landscape. The presence of coal mining, oil and gas exploration, agriculture, on-lot septic systems, and commercial development within the basin can introduce contaminants altering the natural chemistry of the ground water. Data collected to document...
