Hydraulic fracturing has contaminated some drinking wells but the impact is not widespread, according to a landmark U.S. study of water pollution risks that has both foes and supporters of the drilling method declaring victory.
The draft analysis by the Environmental Protection Agency, released Thursday after three years of study, looked at possible ways fracking could contaminate drinking water. The EPA said these include spills of the fracking fluids, poor wastewater disposal or migration of chemicals shot underground to break apart shale rock.
“We conclude there are above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water resources,” the EPA said in the report. But, “we did not find evidence that these mechanisms have led to widespread, systemic impacts on drinking water resources.”
