Wastewater disposal is greatest threat to drinking water from gas fracking operations, say researchers

A new study has found that fracking for natural gas poses the greatest threat to waterways and drinking water via approved, regular disposal of “fracking water” at municipal and industrial wastewater treatment facilities.

This type of disposal, used in the Marcellus Shale region in the Northeast U.S., is failing to adequately cleanse the wastewater produced by gas wells, according to the study. The result is that ostensibly “treated” water is being discharged into streams and waterways still contaminated with chemicals and minerals that accumulate during the fracking process.
