Government Accountability Office study reports that oil and gas drilling could pose risk to the environment and public health

A new study by the independent, nonpartisan Government Accountability Office found that while hydraulic fracturing has not been found to be a cause of groundwater contamination according to regulators in eight states, shale gas and oil drilling does still pose environmental and public health risks, The Columbus Dispatch reports. The extent of these risks is unknown, the study said, but noted that “underground migration of gases and chemicals poses a risk of contamination to water quality,” potentially due to faulty seals on gas wells, the article said.
