PA DEP to Study Radiation Related to Marcellus Shale from State Impact PA
"The Pennsylvania Department of Environmental Protection plans to study levels of naturally occurring radioactivity in materials associated with oil and gas drilling. The announcement comes  almost two years after a series of reports in the New York Times revealed radioactive waste water from gas drilling was discharged into Pennsylvania’s rivers and streams. The industry has since stopped the practice, but the DEP says it plans to analyze radioactivity in frack flowback water, drill cuttings, drill mud, and the levels in equipment such as pipes, well casings storage tanks, treatment systems and trucks."
