It is believed that fracking chemical and ,flow-back fluids, contain element endocrine disruptors. A lack of disclosure by ,shale gas, extracting firms, however, makes the process difficult to evaluate potential adverse effects of these chemicals. Hence, the cumulative adverse impacts of these ,fluids, remain unknown (Dechert 1).

Therefore, when flowback fluid is recycled and reused to prepare the cross-linked gel for fracturing, all components that are unfavorable to its gelation and cross-linking must be removed or shielded.

2/10/2017, · ,Shale gas, is known as one of the unconventional natural ,gas,; ... The second stage is known as ,flow-back, in which some of the injected water is released and comes out to the surface with the produced ,gas,. ,Flow-back fluids, can be treated and reused in another hydraulic fracture job which can decrease the volume of the generated wastewater.

After the shale has been fractured, the fracturing fluids flow back up the well to the surface along with the gas and highly saline brines from the shale formation. The process is contained but some people fear that toxic fracturing fluid chemicals in this flowback could contaminate nearby water supplies if they're accidentally spilled or insufficiently treated before being disposed of.

While some portion of hydraulic fracturing flow back fluid may be recycled or reused in subsequent hydraulic fracturing treatments, the majority of these fluids are disposed of by injection into geologically, confined underground formations through injection wells permitted through the Railroad Commission’s EPA-delegated Underground Injection Control (UIC) program under the federal Safe Drinking Water Act.

In addition, fresh water scarcity in dry regions or during periods of drought could limit shale gas development. This paper explores the possibility of using alternative water sources and their impact on NORM levels through blending acid mine drainage (AMD) effluent with recycled hydraulic fracturing flowback fluids (HFFFs).
