An Environmental Protection Agency report released in June on the impacts of fracking on water quality is now being called into question — by none other than the agency's own scientists.
The report initially did not find "widespread, systemic impacts" on drinking water resources close to fracking sites. But the EPA's Science Advisory Board responded in December, after the report was released, that "major findings are ambiguous or inconsistent with the observations/data presented in this report," according to Bloomberg.
The controversy rests on one key aspect of the report's findings. It states that the "...number of identified cases [of contaminated wells], however, was small compared to the number of hydraulically fractured wells."
While this may be accurate, the report goes on to admit that insufficient long-term data on pre and post fracking water quality could have limited their results, and may not explicitly point to the "rarity of effects on drinking water resources." MORE
