Fracking Is Already Straining U.S. Water Supplies

“Every fracking job requires 2 million to 4 million gallons of water, according to the Groundwater Protection Council. The Environmental Protection Agency, or EPA, has estimated that the 35,000 oil and gas wells used for fracking consume between 70 billion and 140 billion gallons of water each year. That’s about equal, EPA says, to the water use in 40 to 80 cities with populations of 50,000 people, or one to two cities with a population of 2.5 million each.

Some of the most intensive oil and gas development in the nation is occurring in regions where water is already at a premium. A paper published last month by Ceres, a nonprofit that works on sustainability issues, looked at 25,000 shale oil and shale gas wells in operation and monitored by an industry-tied reporting website called FracFocus.

Ceres found that 47 percent of these wells were in areas “with high or extremely high water stress” because of large withdrawals for use by industry, agriculture, and municipalities. In Colorado, for example, 92 percent of the wells were in extremely high water-stress areas, and in Texas more than half were in high or extremely high water-stress areas.”
