The Entire Oil And Gas Industry Has Its Eyes On A Tiny Town In Wyoming



Most scientists have long maintained it was highly unlikely that chemicals pumped into the ground for fracking gas could move all the way up through bedrock and into the water table. 

But that appears to be exactly what has happened underneath Pavillion, Wyoming, population 213. 

Last week, the Environmental Protection Agency announced new USGS test results were consistent with its December tests that fracking likely contaminated groundwater there.

Duke University Professor Rob Jackson has studied the effects of fracking in Pennsylvania and (when they were still active) New York. 

He's also been closely following the Pavillion study.

"The industry likes to say there's never been a case of fracking contaminating groundwater," he told us by phone. "What made the EPA report so controversial is that they concluded that's what happened."

Yesterday, the EPA found methane had leaked into a watertable in Dimock, Pennsylvania where drillers are tapping the Marcellus shale.

But those results are less disturbing than Pavillion, Jackson said.  The contamination in Dimock was most likely because of a crack in pipe, something relatively easy to address.

And the drilling that occurs in the Marcellus takes place thousands of feet below aquifers — unlike the situation potentially unfolding in Pavillion, where the drilling, which was performed by the company Encana, reaches less than 1,000 feet below the surface. 

"If it's moved up into the rock, that's a harder problem to fix than a poorly constructed pipe," Jackson said.

Doug Hock, a spokesman for Encana, said in an email there was nothing surprising in the U! SGS' res ults.

More important is the fact that USGS only sampled one of the two monitoring wells. This goes to the heart of concerns raised by state and federal agencies, as well as Encana—EPA’s wells are improperly constructed. Specifically, the report seems to indicate that USGS declined to sample MW02 because the well could not provide a sample that was representative of actual water quality conditions.

The EPA has not announced when it will finalize its conclusions for Pavillion — the agency is still accepting public comments on its findings from December.

Jackson believes whatever the outcome, fracking will be here to stay.

But the results will significantly raise the stakes regardless. 

"It will still be controversial," he said. "The take home message in Pavillion is, don't frack a well so close to surface."
