EPA fracking study on water impacts comes up dry

On 4 June 2015, the US Environmental Protection Agency released a draft assessment report on the impact of hydraulic fracturing on drinking water. The peer-reviewed study analyzed over 950 sources of existing data and literature, concluding that the practice does not have "systemic, widespread" impacts on water resources. While the study notes some cases of contamination, these instances are a result of faulty well design or mechanical failures rather than inherent process risk.
