EPA fracking report offers few answers on drinking water

The report removes a finding from a draft issued last year indicating that fracking has not caused “widespread, systemic” harm to drinking water in the United States. Industry groups had hailed the draft EPA study as proof that fracking is safe, while environmentalists seized on the report’s identification of cases where fracking-related activities polluted drinking water.

Fracking involves pumping huge volumes of water, sand and chemicals underground to split open rock formations so oil and gas will flow. The practice has spurred an ongoing energy boom but has raised widespread concerns that it might lead to groundwater contamination, increased air pollution and even earthquakes.

The reactions were reversed on Tuesday. Environmentalists cheered the new report as proof that fracking threatens drinking water, while industry groups complained the Obama administration had yielded to political pressure on its way out the door.

“We are glad EPA resisted oil and gas industry spin, followed the science and delivered the facts,” said John Noel, oil and gas campaigns co-ordinator for Clean Water Action, an advocacy group.

An oil industry spokesman called the report an “absurd” reversal that changes a science-based conclusion to one “based in political ambiguity” just weeks before President Barack Obama leaves office.

“The agency has walked away from nearly a thousand sources of information from … technical reports and peer-reviewed scientific reports demonstrating that … hydraulic fracturing does not lead to widespread, systemic impacts to drinking water resources,” said Erik Milito of the American Petroleum Institute, an industry lobbying group.

The fracking study makes a mockery of frequent pledges by Obama and EPA Administrator Gina McCarthy to follow science as they make decisions, Milito said. “We look forward to working with the new administration to instil fact-based science back into the public policy process,” he said of President-elect Donald Trump.

Tom Burke, EPA’s science adviser and a deputy assistant administrator, said in an interview that the removal of the phrase about “widespread, systemic” impacts came at the urging of the EPA’s Science Advisory Board.

“Data gaps did not allow us to quantify how widespread the impacts are,” Burke said.

Environmental groups have claimed that the finding of no widespread harm was inserted into the draft report at the insistence of the White House. Obama supports fracking as part of a wide-ranging energy strategy.

An EPA spokeswoman denied any political pressure.

The final report found specific instances where poorly constructed drilling wells, improper wastewater management or other problems affected drinking water. Impacts generally occurred near drilling sites and ranged from temporary changes in water quality to rendering private drinking wells unusable, the report said.

The number of contamination cases was small compared to the tens of thousands of wells that are fracked nationwide, the EPA said.

Congress ordered the report in 2010, as a surge in fracking fueled a nationwide boom in production of oil and natural gas.
