EPAofficials say newgroundwater tests in Pavillion, Wyoming, show chemicals in the water thatcan be linked to oil companies’ shalegas operations, termed "fracking,” writes Norwegian business daily DagensNæringsliv (DN).Fracking involves pumping water and chemicals into a reservoir to breakup shale rocklayers and release the gas trapped there.
Methane, ethane, propane, diesel oil

Statoil has no businessin Wyoming where the polluted groundwater has now been discovered,but does have shale gas operations inTexas, North Dakota,and Montana.
TheEPA tests have identified methane, ethane, propane, diesel oil components and phenol, amongst other things.These findings indicate that bothgas and the synthetic chemicals used in fracking havecontaminated the groundwater. Also on Aenergy:
