Fears of alleged environmental effects of hydraulic fracturing are "anecdotal and overstated," writes Michael Lynch, president and director of global petroleum service at Strategic Energy & Economic Research. The only time fracking chemicals have been found in water supplies was in Wyoming, and that finding is preliminary. Fracking opponents often raise unrelated fears, which could mean that "claims of fracking dangers will prove to be another case of bad science rather than a serious environmental risk," Lynch writes.
