"Scientific and political disputes over drilling Marcellus shale for natural gas have focused primarily on the environmental effects of pumping millions of gallons of water and chemicals deep underground to blast through rocks to release the natural gas.
But University at Buffalo researchers have now found that that process - called hydraulic fracturing or 'fracking' - also causes uranium that is naturally trapped inside Marcellus shale to be released, raising additional environmental concerns.
The research will be presented at the annual meeting of the Geological Society of America in Denver on Nov. 2." More>>>>
