In ,general,, desalination of recycle ,flowback, water is becoming less important. New formulations of salt-tolerant polymers and fluids are being developed and applied. Some of the HF fluids are more expensive on a per pound basis, but become cost-competitive when overall reduction in water source, treatment, and disposal costs are taken into account.

Hydraulic ,fracturing flowback, waters at early time points (1–14 days post-,fracturing,) exhibit dramatic shifts in the microbial community (Fig. 4). After injection into the deep subsurface, fluids returning to the surface immediately show enrichment of different microbial taxa compared to input fluids, with dynamic taxa changes over the next 2 weeks.
