Feds Link Water Contamination to Fracking for the First Time  

Posted by Big Gav in ,

ProPublica has a look at a new study of fracking fluids contaminating underground water in the US - Feds Link 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 known to be used in frack fluids.

“The presence of synthetic compounds such as glycol ethers … 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,” the draft report states. “Alternative explanations were carefully considered.”

The agency’s 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 aren’t connected to fracking.
