High radioactivity found in USA

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. 

Fracking is the extraction of oil and gas by injecting water to break rock formations deep underground. Use of the process has increased rapidly in the US in recent years, yet scientists who have studied the practice warn of climate-damaging methane emissions and radioactive effects that come with it.......
