Study Measures Fracking’s Impact On Nearby Surface Water Quality
A new study correlates poorer surface water quality with nearby hydraulic fracturing but finds that the impacts aren’t major enough to be considered harmful by federal regulators. However, the researchers noted they weren’t able to study “potentially more dangerous” substances related to fracking because of a lack of data.
While some published studies have already linked groundwater contamination with hydraulic fracking activity, one of the researchers behind the study, Christian Leuz of the University of Chicago, said through a press release that their work was the “first large-sample evidence showing that hydraulic fracturing is related to the quality of nearby surface waters for several U.S. shales.”
The study, published in the journal Science, found “small but consistent” increases in the concentration of nonbiodegradable salts in watersheds where new hydraulic fracturing activities were taking place.
