Traces of chemicals commonly used for fracking were found in the drinking water supply of three homes in Bradford County in the US state of Pennsylvania, a study revealed on May 18.
The investigation, which appeared in scientific journal Proceedings of the National Academy of Sciences, proved the long-held worry of damaging underground drinking water sources from the method of extracting gases known as hydraulic fracturing. The report explicitly links the practice with the affected water systems.
“This is the first case published with a complete story showing organic compounds attributed to shale gas development found in a homeowner’s well,” said Susan Brantley, one of the study’s authors and a geoscientist from Pennsylvania State University.
