Fracking linked to radioactive river water in Pa. River water in western Pennsylvania has elevated levels of radioactivity, some of it from fluids discharged after fracking for natural gas in the Marcellus Shale area, says a Duke University study Wednesday. Post to Facebook.
The formation also extends into Pennsylvania, New York, Ohio, and Virginia. Fluid recovered from the well after the fracking is completed is called flowback fluid or waste water. Only 10-40% of the frack fluid is recovered.
