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