1/2/2013, · In general terms, it is more cost effective to re-use the ,flow back, water used in the hydraulic ,fracturing, process than to clean up to the levels necessary for surface discharge. The ,flow back fluids, have increased levels of salinity, as well as some metals (barium, strontium), low level radionuclides, and some volatiles (Burnett, 2009).
