Dangerous amount of Radiation found in stream with Fracking Water.

Last week new concerns came to light regarding the treatment and disposal of fracking wastewater. First a  report by Environment America shows that as fracking expands across the US, the sheer amount of wastewater produced in 17 shale states – to the tune of 280 billion gallons in 2012 – is problematic.
Over two years the Duke research team, led by the well-recognized duo of Professors Robert Jackson and Avner Vengosh, monitored Blacklick Creek and found that  radium-226 – a naturally occurring radioactive material found in rock – appeared in concentrations unsafe for human exposure.
Much of the radium was removed from the wastewater by the Josephine Brine Treatment Facility, yet their operations were not able to completely eliminate the element, resulting in discharges " roughly 200 times higher than background levels."
