Demand for high-volume, short duration water withdrawals could create water stress to aquatic organisms in the Fayetteville Shale streams of Arkansas sourced for hydraulic fracturing fluids this article in the journal Environmental Science and Technology suggests. Authors estimate potential water stress using permitted water withdrawal volumes and actual water withdrawals compared to monthly median, low, and high streamflows. Findings indicate that freshwater usage for hydraulic fracturing could potentially affect aquatic organisms in 7-51 percent of the catchments depending on the month. If 100 percent of wastewater was recycled, the potential impact drops. Authors suggest that improved monitoring and access to water withdrawal and streamflow data are needed to ensure protection of streams not only as sources of drinking water, but aquatic habitats.
