According to Business Week, a report, published in the Proceedings of the National Academy of Sciences, says an analysis of 426 shallow groundwater samples found matches with brine found in rock more than a mile deep. The study suggests that brine from fracking can migrate through natural routes.

“The industry has always claimed that this is a separation zone, and there is no way fluids could flow” from the shale to the aquifers, Avner Vengosh, a professor at the Nicholas School of the Environment at Duke University and one of the study’s eight authors, said in an interview. “We see evidence of hydrologic connectivity.”

Those in the industry are looking at the study in a different light:

“The good news is that the researchers make it crystal clear that the phenomena they observed had nothing to do with shale development,” Chris Tucker, a spokesman for the industry- backed group Energy In Depth in Washington, said in an e-mail.”
