"Fracking Shown to Mobilize Uranium in Marcellus Shale"

"BUFFALO, N.Y. -- Fracking -- pumping millions of gallons of water and chemicals deep underground to fracture shale rock, releasing the natural gas it contains -- is controversial because it may pollute groundwater used for drinking with proprietary chemical cocktails that drilling companies keep to themselves.

Now scientists at the State University of New York at Buffalo have found that a chemical everyone recognizes - uranium - also can be released by fracking in Marcellus shale and that it too may pollute groundwater.

The researchers examined uranium released by fracking in Marcellus shale, a massive rock formation that stretches from New York through Pennsylvania, Ohio and West Virginia, considered to be the nation's largest source of natural gas."
