Unless you are on an ultra high sea salt, high barium, high arsenic and high radium 226 diet. Which may account for all the novel ways the frackers are trying to make billions of gallons of the stuff disappear – as “de-icer” onto roads, down a shallow disposal well, or into muni treatment plants – or, condensed to a toxic, radioactive sludge, into a landfill near you. So that your kids or grandkids can drink it. . . and get sick. As explained in a new study from PSU:

“Large quantities of highly saline brine ﬂow from gas wells in the Marcellus Formation after hydraulic
stimulation (‘‘fracking’’). This study assesses the composition of these ﬂowback waters from the Marcellus shale in Pennsylvania, USA. Concentrations of most inorganic components of ﬂowback water (Cl, Br,Na, K, Ca, Mg, Sr, Ba, Ra, Fe, Mn, total dissolved solids, and others) increase with time from a well after hydraulic stimulation. Based on results in several datasets reported here, the greatest concentration of Cl in ﬂowback water is 151,000 mg/L. For total Ra (combined
226 Ra and 228 Ra) in ﬂowback, the highest level reported is 6540 pCi/L. Flowback waters from hydraulic fracturing of Marcellus wells resemble brines produced from conventional gas wells that tap into other Paleozoic formations in the region.
The Br/Cl ratio and other parameters indicate that both types of brine formed by the evaporation of seawater followed by dolomitization, sulfate reduction and subsurface mixing with seawater and/or freshwater. Trends and relationships in brine composition indicate that (1) increased salt concentration in ﬂowback is not mainly caused by dissolution of salt or other minerals in rock units, (2) the ﬂowback waters represent a mixture of injection waters with highly concentrated in situ brines similar to those in the other formations, and (3) these waters contain concentrations of Ra and Ba that are commonly hundreds of times the US drinking water standards.”
