Study Finds Methane Contamination From Fracking

Law360, New York (May 9, 2011, 8:26 PM EDT) -- A study released Monday documented systematic evidence for methane contamination of drinking water in areas where natural gas is being extracted from shale by the controversial method of hydraulic fracturing.

The study, published in Proceedings of the National Academy of Sciences, found that methane concentrations were 17 times higher on average in shallow wells from active drilling and extraction areas than in wells from nonactive areas. This constitutes a potential explosion hazard, according to the study, which was authored by four professors and research associates at...
