Hydraulic ,fracturing, for natural gas extn. from shale produces ,waste, brine known as ,flowback, that is impounded at the surface prior to reuse and/or disposal. During impoundment, microbial activity can alter the fate of metals including radionuclides, give rise to odorous compds., and result in biocorrosion that complicates water and ,waste, management and increases prodn. costs.

Fracking Water: It's Just So Hard to Clean | HuffPost

Flowback, water (which literally “flows back” during the fracking process) is a mixture of fracking ,fluid, and formation water (i.e., water rich in brine from the targeted shale gas-rich rock). Once the chemistry of the water coming out of the well resembles the rock formation rather than the fracking ,fluid,, it is known as produced water and can continue to flow as long as a well is in operation.
