Fracking waste contaminates Penn. watershed with radioactive material

Stream sediments in Pennsylvania downstream from two fracking wastewater treatment facilities were found to contain radioactive material and carcinogens, according to study scientists from Penn State, Colorado State and Dartmouth universities.
The study’s findings, published Thursday, came after Penn State’s Bill Burgos and his fellow scientists sought to discover what had been the effect of the strategy of treating and releasing fracking wastewater, according to the Independent.
They sampled sediments and groundwater from the Conemaugh River water, downstream from two facilities that were created to make the water used in the fracking process fit for release into the environment.
“Isotopic ratios of 226Ra/228Ra and 87Sr/86Sr identified that peak concentrations of Ra and Sr were likely sourced from wastewaters that originated from the Marcellus Shale formation,” according to the study Watershed-Scale Impacts for Surface Water Disposal of Oil and Gas Wastewater in Western Pennsylvania.
Their analysis detected peak concentrations of radium, chloride, barium, strontium, radium and organic compounds in Conemaugh River watershed. The two major classes of organic contaminants included nonylphenol ethoxylates, endocrine-disrupting chemicals, and polycyclic aromatic hydrocarbons, known carcinogens.
When scientists examined steam sediments in Blacklick Creek, just downstream from one treatment plant, it was found to contain about 200 times the level of radium found upstream of the plant.
The highest concentration of radium was just 14 percent below the level at which it would have to be treated as radioactive waste in some US states.
