Fracking water usage
New study shows that fracking boom is happening in places that can least afford to lose precious water supplies

Almost half (47%) of all U.S. wells are being developed in regions with high to extremely high water stress. This means that more than 80 percent of the annual available water is already allocated to municipal, industrial and agricultural users in these regions. (Source: Ceres)
In Texas, which includes the rapidly developing Eagle Ford and Permian Basin shale plays, more than half (52 percent) of the wells were in high or extreme high water stress areas. In Colorado and California, 97 and 96 percent of the wells, respectively, were in regions with high or extremely high water stress. Nearly comparable trends were also shown in New Mexico, Utah and Wyoming.
Among hundreds of hydraulic fracturing companies whose water use was evaluated, those with the highest exposure to water sourcing risk are Anadarako (APC), Encana (ECA), Pioneer (PXD) and Apache (APA). Most of the wells being developed by each of these companies are in regions of high or extreme water stress. The top three service providers, Halliburton, (HAL) Schlumberger (SLB) and Baker Hughes (BHI), handled about half of the water used for hydraulic fracturing nationally and also face water sourcing risks.
Although water use for hydraulic fracturing is often less than two percent of state water demands, the impacts can be large at the local level, sometimes exceeding the water used by all of the residents in a county.
