This past Thursday, in a hearing titled "Fostering Quality Science at EPA: The Need for Common Sense Reform," Republicans on a U.S. House of Representatives energy and environment panel criticized a recently released U.S. Environmental Protection Agency plan to study any potentially detrimental effects of fracking on drinking water supplies. Perhaps informed by Secretary Krancer's Capitol Hill testimony from the day before, the Republican panel members were quick to point out that roughly 1.2 million wells have already been drilled using this technique, and there has yet to be a documented report of drinking water contamination. As such, these committee members found the EPA's suggested use of government funds to be lacking in common sense. The EPA responded by noting that until studies were done, or evidence of detrimental effects were sought, it was clear that no such evidence could be found. You can find more information here.
