Researchers believe they have found an unlikely way to decrease the radioactivity of some hydraulic fracturing wastewater: Mix it with the hazardous drainage from mining operations. The wastewater is created when some of the chemical-laced water used to fracture thick underground rocks flows back out of the wellbore. The water is tainted with chemicals, toxins and in some parts of the country — such as Pennsylvania — naturally occurring radioactive materials, such as radium. Research has shown that even wastewater that had been treated with conventional means was changing the chemistry of rivers when discharged into waterways. bit.ly/1cvwBk9
