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.
Fracking fluids are complex mixtures of chemicals, water, and sand that are unique to each company. Like Colonel Sandersâ 11 secret herbs and spices, the makeup of this fluid is a jealously guarded trade secret that the oil and gas companies typically refuse to divulge, even under pressure.ince the rock layer is porous, water alone cannot be used as fracking fluid. Water would simply sink into the rock without cracking the substrate. For this reason, the drilling companies must make a slick mixture of fracking fluids.
