Methane in well water from gas fracking
Many of you may have seen this kind of video, showing the effects of methane in drinking water near some shale gas extraction wells: Before now, I’ve never known what to make of this kind of thing. Is this a very rare, if spectacular occurence, or is it common where shale gas drilling goes on? Now, there is a paper in this weeks PNAS, Methane contamination of drinking water accompanying gas-well drilling and hydraulic fracturing by Osborn et al, researchers at Duke University. It appears to answer the question, and the answer is not good.
