The natural gas industry has argued that flawed casing practices used while drilling shale-gas wells were responsible for methane contamination in drinking water supplies surrounding shale-gas wells.

FORBES: Pennsylvania Pins Record Fine on Shale-Gas Producer

Earlier this month, scientists at Duke University published a paper in the Proceedings of the National Academies that provided evidence of a link between shale-gas wells and methane contamination in nearby drinking water supplied.

Natural gas formations are thousands of feet below drinking water aquifers so for contamination to occur the fracking solution would have to move through multiple layers of rocks.
