"In Pennsylvania, oil and gas wastewater is sometimes treated at brine
treatment facilities and discharged to local streams. This study
examined the water quality and isotopic compositions of discharged
effluents, surface waters, and stream sediments associated with a
treatment facility site in western Pennsylvania. The elevated levels of
chloride and bromide, combined with the strontium, radium, oxygen, and
hydrogen isotopic compositions of the effluents reflect the composition
of Marcellus Shale produced waters ... Radium-266 levels in stream sediments (544–8759 Bq/kg) at the point of discharge were ca. 200
times greater than upstream and background sediments (22–44 Bq/kg) and
above radioactive waste disposal threshold regulations, posing potential
environmental risks of radium bioaccumulation in localized areas of
shale gas wastewater disposal."
