Study says hydraulic fracturing of Marcellus shale pollutes water
Bombs, nuclear power plants and groundwater. What do they all have in common? Well, according to a new study published by the University at Buffalo (UB), the answer could soon be uranium.
The study conducted by UB geologist Tracy Bank shows that hydraulic fracture drilling, or fracking, in the Marcellus shale deposit on the East Coast of the United States will result in the pollution of groundwater with uranium. Bank found that naturally occurring uranium trapped in Marcellus shale is released into groundwater following hydraulic fracturing, a practice of pumping high-pressured water and chemicals into rock formations to break up and release elements; in this case, natural gas.
"We found that the uranium and the hydrocarbons are in the same physical space...that they are not just physically—but also chemically—bound. That led me to believe that uranium in solution could be more of an issue because the process of drilling to extract the hydrocarbons could start mobilizing the metals as well, forcing them into the soluble phase and causing them to move around."
Bank’s hypothesis proved correct once samples of Marcellus shale were tested in the laboratory. The implications of the study are significant.Polluting groundwater with uranium, a toxic metal and radioactive element, could cause serious human health impacts if the uranium made its way into municipal drinking water systems or emitted toxic radon gas near communities.
It seems the oil and gas drilling industry would rather not acknowledge the water pollution associated with hydraulic fracturing. Which is why Earthjustice is fighting on Capitol Hill to close a loophole exempting the industry from the Safe Drinking Water Act, challenging backroom deals between government regulators and the oil and gas industry, and fighting for the strongest possible regulations to protect clean air and water supplies.
