The game-changing study from Duke University found that “from 2011 to 2016, the water use per well increased up to 770 percent.” In addition, the toxic wastewater produced in the first year of production jumped up to 1440 percent.
“Previous studies suggested hydraulic fracturing does not use significantly more water than other energy sources, but those findings were based only on aggregated data from the early years of fracking,” explained co-author Avner Vengosh, a professor of geochemistry and water quality at Duke.
