A recent study comparing historic water quality from the Monongahela River Basin in West Virginia found little change in the groundwater and few changes in the surface water samples over the period of time covered by the survey led by the U.S. Geological Survey. A current ground water sampling survey in this area (which has seen shale gas exploration for about the past eight years), showed no significant difference from historical water samples. Surface water samples show increases in pH levels and significantly higher concentrations of chloride and strontium when compared to historic samples, constituents most often associated with the treatment of coal-mine drainage, and the presence of highly concentrated salt water.
