Fracking water poses no threat to groundwater, according to paper

No need to fear the effects of injection well water, according to Pennsylvania State University.

A recent paper explained that the water used for fracking, which is injected into fracking wells along with sand and chemicals to fracture rock that holds shale gas, remains isolated in the rock. Some injected water, called residual treatment water (RTW), does come back to the surface and can be treated once it comes to the surface.

From Pennsylvania State University:

“The researchers report that groundwater contamination is not likely because contaminant delivery rate would be too small even if leakage were possible, but more importantly, upward migration of RTW is not plausible due to capillary and osmotic forces that propel RTW into, not out of, the shale.”

  1. Fracking may not pose a threat to groundwater but the holding tanks or open pits that store frac-water are threats to groundwater, especially when they are damaged or destroyed by storms.
