Doesn’t the EPA say fracking does not harm drinking water?


No. According to the December 2016 EPA report, Hydraulic Fracturing for Oil and Gas: Impacts from the Hydraulic Fracturing Water Cycle on Drinking Water Resources in the United States, “…activities in the hydraulic fracturing water cycle can impact—and have impacted—drinking water resources … combinations of activities and factors highlight, in particular, the vulnerability of ground­ water resources to activities in the hydraulic fractur­ing water cycle.”
