The Battelle Memorial Institute issued a report finding that the Environmental Protection Agency should narrow the focus and increase the rigor of its study on the risks fracking may pose to drinking water. The report, Review of EPA Hydraulic Fracturing Study Plan, found that the agency is overreaching in the scope of its study by including a number of exploration and production activities that are already well known and not specific to fracking, and concluded that the study would benefit from more significant stakeholder collaboration. The agency will release some study findings by the end of this year and the full study in 2014.
