5 Million Gallons of Freshwater Used to Frack Just One Well
Published on by Water Network Research, Official research team of The Water Network in Academic
A lot has been said about the toxic slurry of fracking fluids and its impact on water quality, but what about the millions of gallons of water that's sucked up by the drilling process and its impact on water quantity?
A new study highlights how the five million gallons of freshwater used to fracture just one gas well in the U.S.—or more than enough to fill seven Olympic-size swimming pools—has depleted water levels in up to 51 percent of streams in Arkansas, as Motherboard reported from the research.

The paper, published in the American Chemical Society's journal Environmental Science & Technology, also finds that high-volume, short duration water withdrawals used for fracking fluids creates water stress to aquatic organisms in Fayetteville Shale streams.
These streams—which also supply drinking water to thousands of people in the region—are home to 10 aquatic species that are declining at a concerning rate, according to a release on the study. Depending on the time of year, freshwater usage for fracking could potentially affect aquatic organisms in 7 to 51 percent of the catchments, the research team found. Even if 100 percent of the fracking wastewater were recycled, between 3 to 45 percent of catchments could still be affected.
In the summer especially, drawing out millions of gallons of water from a stream for fracking fluids likely has a significant impact on stream temperatures and stream flow, which affects aquatic insects, fish and bottom-dwelling mussels, the study said.
The purpose of the study is to flesh out the potential impact of fracking on streams around the Fayetteville Shale play, an active gas field in Arkansas where more than 5,000 gas wells were drilled using fracking techniques between 2004 and 2014.
