Are environmentalists telling the truth about fracking? Is the energy industry telling the truth? NBC attempts to sort through the claims and counterclaims.
Bill Dedman and Karen Weintraub write: "It's difficult to find scientists who have not lined up on one side or another on hydraulic fracking for oil and natural gas. The anti-fracking groups have their scientific talking points, and the pro-fracking groups have their counterclaims. Some of the scientists who have put out pro-fracking reports have turned out to be tied to the industry. When even the federal panel formed to study the issue is stacked with industry supporters, it’s hard for environmentalists and health advocates to believe its conclusions.
"'Cutting through the "noise" for the average citizen in indeed extremely difficult,' said Peter Collings, a physics professor at Swarthmore College in Pennsylvania, who has lectured about fracking. The truth about fracking, he said in an e-mail interview, lies 'somewhere in between' what the regulation-hating gas industry tells the public and what the environmentalists claim."
