The House Science, Space and Technology Committee on May 11 questioned Paul Anastas, administrator of EPA's Office of Research and Development whether a proposed study by the Agency to determine if the oil-drilling technique called hydraulic fracturing contaminates drinking water is necessary based on no confirmed incidents of such contamination. Anastas said the study draft plan that was issued in February 2011, is intended to assess if there are factors that could cause potential harm to people and the environment and not intended as a risk assessment. Anastas said the study would cost $4.3 million in fiscal year 2011 and is estimated to cost a total of $12 million. EPA expects the initial results by the end of 2012. Elizabeth Jones, commissioner of the Texas Railroad Commission, which regulates oil and gas extraction in the state testified that no cases of groundwater contamination from hydraulic fracturing ever been confirmed and States could lose $785 billion in revenue as well as jobs if hydraulic fracturing were prohibited. A study by Duke University published May 9 on methane contamination of drinking water wells at three sites in the Northeast found that contamination was substantially higher near natural gas wells, but the contamination did not include fluids used in fracking (see related TWIW story below).
