Bombshell Report Links Water Contamination To Fracking For The First Time

In a first, federal environment officials today scientifically linked underground water pollution with hydraulic fracturing, concluding that contaminants found in central Wyoming were likely caused by the gas drilling process.

The findings by the Environmental Protection Agency come partway through a separate national study by the agency to determine whether fracking presents a risk to water resources.

In the 121-page draft report released today, EPA officials said that the contamination near the town of Pavillion, Wyo., had most likely seeped up from gas wells and contained at least 10 compounds [1] known to be used in frack fluids.

201CThe presence of synthetic compounds such as glycol ethers 2026 and the assortment of other organic components is explained as the result of direct mixing of hydraulic fracturing fluids with ground water in the Pavillion gas field,201D the draft report states. 201CAlternative explanations were carefully considered.201D
The agency2019s findings could be a turning point in the heated national debate about whether contamination from fracking is happening, and are likely to shape how the country regulates and develops natural gas resources in the Marcellus Shale and across the Eastern Appalachian states.

Some of the findings in the report also directly contradict longstanding arguments by the drilling industry for why the fracking process is safe: that hydrologic pressure would naturally force fluids down, not up; that deep geologic layers provide a watertight barrier preventing the movement of chemicals towards the surface; and that the problems with the cement and steel barriers around gas wells aren2019t connected to fracking.
Environmental advocates greeted today2019s report with a sense of vindication and seized the opportunity to argue for stronger federal regulation of fracking.

201CNo one can accurately say that there is 2018no risk2019 where fracking is concerned,201D wrote Amy Mall, a senior policy analyst at the Natural Resources Defense Council, on her blog. 201CThis draft report makes obvious that there are many factors at play, any one of which can go wrong. Much stronger rules are needed to ensure that well construction standards are stronger and reduce threats to drinking water.201D
A spokesman for EnCana, the gas company that owns the Pavillion wells, did not immediately respond to a request for comment. In an email exchange after the EPA released preliminary water test data two weeks ago [2], the spokesman, Doug Hock, denied that the company2019s actions were to blame for the pollution and suggested it was naturally caused.

201CNothing EPA presented suggests anything has changed since August of last year2013 the science remains inconclusive in terms of data, impact, and source,201D Hock wrote. 201CIt is also important to recognize the importance of hydrology and geology with regard to the sampling results in the Pavillion Field. The field consists of gas-bearing zones in the near subsurface, poor general water quality parameters and discontinuous water-bearing zones.201D

The EPA2019s findings immediately triggered what is sure to become a heated political debate as members of Congress consider afresh proposals to regulate fracking. After a phone call with EPA chief Lisa Jackson this morning, Sen. James Inhofe, R-Okla., told a Senate panel that he found the agency2019s report on the Pavillion-area contamination 201Coffensive.201D Inhofe2019s office had challenged the EPA2019s investigation in Wyoming last year, accusing the agency of bias.

Residents began complaining of fouled water near Pavillion in the mid-1990s, and the problems appeared to get worse around 2004. Several residents complained that their well water turned brown shortly after gas wells were fracked nearby [3], and, for a time, gas companies operating in the area supplied replacement drinking water to residents.

Beginning in 2008, the EPA took water samples from resident2019s drinking water wells, finding hydrocarbons and traces of contaminants that seemed like they could be related to fracking [4]. In 2010, another round of sampling confirmed the contamination, and the EPA, along with federal health officials, cautioned residents not to drink their water and to ventilate their homes [5] when they bathed because the methane in the water could cause an explosion.

To confirm their findings, EPA investigators drilled two water monitoring wells to 1,000 feet. The agency released data from these test wells in November that confirmed high levels of carcinogenic chemicals [2] such as benzene, and a chemical compound called 2 Butoxyethanol, which is known to be used in fracking.
