Last week, the U.S. Department of Energy (DOE) told The Associated Press that the preliminary results of its study indicated that that fracking chemicals did not reach drinking water sources at a well site in Greene County, Pennsylvania, in the Marcellus Shale formation. The study, conducted by the DOE’s National Energy Technology Laboratory, is the first performed by government scientists using tracers in fracking fluid. Researchers injected the tracers into fracking fluid at different stages of the fracking process while monitoring existing wells at about 3,000 feet above the fractures, which were roughly 8,000 feet below the surface. DOE found no evidence of the tracers in groundwater at the monitored wells.
