‘Alarming’ presence of radioactivity found by Pennsylvania fracking wastewater study
Researchers have found high levels of radioactivity, salts, and metals in water and sediment located downstream from a treatment facility which processes fracking wastewater from oil and gas production sites in Pennsylvania’s Marcellus shale formation.A Duke University team analyzed water and sediment samples from the Josephine Brine Treatment Facility in Indiana County, Pennsylvania, finding radium levels 200 times greater than samples taken upstream from the plant and far higher than what’s allowed under the Clean Water Act.
Radium is a radioactive metal that can cause diseases like leukemia and other ill-health effects if one is exposed to large amounts over time.
The treatment facility processes flowback water - highly saline and radioactive wastewater that resurfaces from underground after being injected into rocks in the fracking, or hydraulic fracturing, process.
For two years, the Duke team monitored sediment and river water above and below the treatment plant, as well as discharge coming directly from the plant, for various contaminants and levels of radioactivity. In the discharge and downstream water, researchers also found high levels of chloride, sulphate, and bromide, which can interact with chlorine and ozone - used to disinfect river water for drinking -to create a toxic byproduct.
"The occurrence of radium is alarming - this is a radioactive constituent that is likely to increase rates of genetic mutation" and can be "a significant radioactive health hazard for humans," said William Schlesinger, a researcher and president of the Cary Institute of Ecosystem Studies, who wasn't involved in the study.
