Shale gas drinking water pollution proven

The US Environmental Protection Agency has found petroleum and synthetic chemicals residues in drinking water in a shale gas area for the first time.

Fracking involves pumping water and chemicals into a reservoir to break up shale rock layers and release the gas trapped there.
EPA officials say new groundwater tests in Pavillion, Wyoming, show chemicals in the water that can be linked to oil companies’ shale gas operations, termed "fracking,” writes Norwegian business daily Dagens Næringsliv (DN).

Fracking involves pumping water and chemicals into a reservoir to break up shale rock layers and release the gas trapped there.

Methane, ethane, propane, diesel oil

Aftenbladet has previously visited another shale gas area The Marcellus Shale located in the US’ northeastern part, where Statoil and other companies operate.

Statoil has no business in Wyoming where the polluted groundwater has now been discovered, but does have shale gas operations in Texas, North Dakota, and Montana.

Norway-based Statoil is expanding internationally and into so-called unconventional resources as output from aging fields off its home country’s coast declines.

The EPA tests have identified methane, ethane, propane, diesel oil components and phenol, amongst other things. These findings indicate that both gas and the synthetic chemicals used in fracking have contaminated the groundwater.
