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 fire was caused by the ignition of hydrocarbon vapor released during the off-loading of basic sediment and water (BS&W) from the two vacuum trucks into an open area collection pit. BS&W is an oil/gas exploration and production (E&P) waste liquid. The BS&W was contaminated with highly flammable condensate. During the off-loading, vapor off-gassed from the BS&W and was drawn into the air intakes of the vacuum trucks' running diesel engines. As a result, the engines began to race and backfire.
