1. HYDRAULIC FRACTURING:
EPA report defends Pavillion water testing methods
U.S. EPA scientists are defending the methods they used to test a key well in the Pavillion, Wyo., hydraulic fracturing water contamination investigation. The agency released results Wednesday from a second round of testing done in April. It said those results are consistent with its preliminary December 2011 report finding that there was fracturing fluid in groundwater in the Pavillion area.
