Experts: Fracking Depletes Water Supply


When water is used for fracking, it's used to extinction.

"It's taken out of the hydrological cycle, never used again," Phillip Doe, a former environmental compliance officer for the U.S. Bureau of Reclamation, said Thursday. "When they say 5 million gallons for a frack, they're talking about 5 million gallons that will never see light again, and that's if they're lucky."

Speaking during a League of Women Voters Cross Currents forum on hydraulic fracturing, or "fracking," for oil and gas drilling, Doe said one of the biggest challenges facing the Front Range today is the amount of water used for drilling for oil and natural gas. That's because water used for agriculture and most other uses is returned into the hydrological cycle and used again.

But most water used for fracking is not.

Fracking is a technology used by the energy industry to fracture underground rock formations as a way to stimulate the flow of oil or natural gas during the well drilling process.

Between 1 million and 5 million gallons of water mixed with sand and toxic chemicals are injected thousands of feet into the ground, a process environmentalists and some residents of oil fields worry may contaminate ground water.

Fracking is a growing concern because oil and gas development is moving closer to homes on the Front Range. The number of wells in northeast Colorado that are fracked has increased in the past few years because of the rush to explore and drill the Niobrara shale.
