E.P.A. Says Hydraulic Fracturing Likely Marred Wyoming Water – NYTimes.com

The energy industry has long stressed that fracking and water contamination have never been definitively linked.

“When considered together with other lines of evidence, the data indicates likely impact to ground water that can be explained by hydraulic fracturing,” the draft study said. And perhaps just as crucially, the evidence also suggested that seepage of natural gas itself had increased around the drilling sites. Natural gas is often mixed with other elements, including methane, which can taint water supplies.

“Data suggest that enhanced migration of gas has occurred within ground water at depths used for domestic water supply,” said the draft study, which will now be sent for scientific peer review and public comment.
