Fracking plays active role in generating toxic metal wastewater, study finds http://www.sciencedaily.com/releases/2015/12/151215134653.htm

Posted: 15 Dec 2015 10:46 AM PST The production of hazardous wastewater in hydraulic fracturing is assumed to be partly due to chemicals introduced into injected freshwater when it mixes with highly saline brine naturally present in the rock. But a new study investigating the toxic metal barium in fracking wastewater finds that chemical reactions between injected freshwater and the fractured shale itself could play a major role. http://feeds.feedburner.com/~ff/sciencedaily/top_news/top_environment?a=e408RmFbhyk:lNLIR9wj9eE:Gqkty0xVXF4

I posted this on the Marcellus Campaign Facebook page, but think it is important enough to spread around via other lists etc. fyi, paul w.
