"U.S. EPA's science advisers are criticizing the agency's June announcement dismissing the dangers to drinking water from hydraulic fracturing.

They are saying the assertion that EPA's study shows fracturing hasn't led to 'widespread, systemic' problems with drinking water from fracturing needs to be changed, because the terms are ill-defined.

'There's agreement the sentence needs to be modified,' said David Dzombak, a Carnegie Mellon University professor chairing the EPA scientific advisory panel conducting a peer review of the agency's hydraulic fracturing study, released in June. 'The sentence is ambiguous and requires clarification.'"
