    • Impacts of shale gas wastewater disposal on water quality in western Pennsylvania. 

      Warner, Nathaniel R; Christie, Cidney A; Jackson, Robert B; Vengosh, Avner (Environ Sci Technol, 2013-10-15)
      The safe disposal of liquid wastes associated with oil and gas production in the United States is a major challenge given their large volumes and typically high levels of contaminants. In Pennsylvania, oil and gas wastewater ...
    • Isotopic imprints of mountaintop mining contaminants. 

      Vengosh, Avner; Lindberg, T Ty; Merola, Brittany R; Ruhl, Laura; Warner, Nathaniel R; White, Alissa; Dwyer, Gary S; ... (8 authors) (Environ Sci Technol, 2013-09-03)
      Mountaintop mining (MTM) is the primary procedure for surface coal exploration within the central Appalachian region of the eastern United States, and it is known to contaminate streams in local watersheds. In this study, ...
    • Methane contamination of drinking water accompanying gas-well drilling and hydraulic fracturing 

      Osborn, Stephen G; Vengosh, Avner; Warner, Nathaniel R; Jackson, Robert B (2011-05-09)
      Directional drilling and hydraulic-fracturing technologies are dramatically increasing natural-gas extraction. In aquifers overlying the Marcellus and Utica shale formations of northeastern Pennsylvania and upstate New York, ...

      Jackson, Robert; Osborn, Stephen; Vengosh, Avner; Warner, Nathaniel R (Proc Natl Acad Sci U S A, 2011-05-17)
      Directional drilling and hydraulic-fracturing technologies are dramatically increasing natural-gas extraction. In aquifers overlying the Marcellus and Utica shale formations of northeastern Pennsylvania and upstate New York, ...
    • Radium and barium removal through blending hydraulic fracturing fluids with acid mine drainage. 

      Kondash, Andrew J; Warner, Nathaniel R; Lahav, Ori; Vengosh, Avner (Environ Sci Technol, 2014-01-21)
      Wastewaters generated during hydraulic fracturing of the Marcellus Shale typically contain high concentrations of salts, naturally occurring radioactive material (NORM), and metals, such as barium, that pose environmental ...
