EPA study on fracking finds no widespread harm to drinking water
WASHINGTON _ Hydraulic fracturing in thousands of oil and gas wells has had relatively no impact on drinking water, according to a five-year study released in draft form on Thursday by the Environmental Protection Agency.
Though there are mechanisms by which "fracking" could contaminate drinking water, researchers "did not find evidence that these mechanisms have led to widespread, systemic impacts on drinking water resources in the United States," the draft report states.
Energy state lawmakers and the oil and gas industry hailed the findings as confirming their oft-state confidence in the safety of fracking.
Environmental groups that have warned about fracking for years criticized the study, with one saying it had been heavily influenced by the energy industry.
