Penn State Study Links Fracking Sites to Elevated Radium and Salinity in Southwestern Pennsylvania Groundwater

Harrisburg Lancaster Lebanon York, PA, October 1, 2026 —

Researchers from Penn State University have conducted a study examining shallow groundwater quality in southwestern Pennsylvania, with a particular focus on Washington County, in areas proximate to oil and gas extraction sites.

The study’s initial findings revealed generally low levels of radium in the tested groundwater samples. Radium traces found in samples that appeared to be mixed with brine were below established regulatory limits.

However, the research noted a correlation between proximity to oil and gas infrastructure and higher concentrations of radium. Specifically, elevated radium levels were detected in samples collected within a three-kilometer radius of oil and gas impoundments and reported spills.

The researchers pointed out limitations in their data concerning extremely close proximity to extraction sites. They stated that there were insufficient samples taken from areas located very near (within 1 kilometer) oil and gas sites to draw definitive conclusions regarding radium contamination in those immediate vicinities. The name of the specific contractor or company operating these sites was not provided in the study’s findings.

Beyond radium, the study also raised concerns regarding elevated salinity levels detected in the groundwater. The researchers indicated that increased salinity, irrespective of its origin, has the potential to cause pipe corrosion. This corrosion, in turn, can lead to the release of metals into the water supply.

The study’s methodology and the specific dates of sample collection were not detailed in the provided summary. The exact impact of the elevated salinity on local water infrastructure or public health was not specified.
