Hydrocarbon Extraction and Risk to Groundwater in Pennsylvania: Part 2. An Analysis of Water Quality in the Oldest Hydrocarbon Basin in the United States, the Part 2 study led by co-principal investigators Jennifer Baka and Susan L. Brantley at Pennsylvania State University, discusses 97 water samples collected and analyzed from private wells, springs, and streams in areas where Part 1 indicated that groundwater may have been affected by unconventional oil and gas development (UOGD).

A Groundwater Modeling Framework for Elucidating Community Exposures Across the Marcellus Region to Contamination Associated with Oil and Gas Development, a study led by James E. Saiers at Yale University, provides a groundwater modeling approach using data from over 25,000 well pads in the Marcellus region to estimate the likelihood of a spill associated with unconventional oil and gas development (UOGD) reaching the residential groundwater supply.
