The EPA released today an interim report on its study of Possible Impacts of Hydraulic Fracturing On Drinking Water. http://www.epa.gov/hfstudy/. The EPA also scheduled webinars for January 3 and 4 to discuss the interim report.
The EPA was mandated by Congress to conduct this study, and the study will not be completed until 2014. The interim report amounts to a status report on the study but reaches no conclusions.
