Fracking Research So Far Finds No Water Taint Near Drilling Site

Energy Department researchers so far have found “nothing of concern” in a study of whether chemicals used in hydraulic fracturing for natural gas at one site in Pennsylvania traveled toward shallower groundwater.

The preliminary evidence, if ratified in a final report, would bolster claims by the industry that the boom in drilling doesn’t pose risks to drinking water. Chances are low that fluids pumped more than a mile underground to free trapped gas could leak and contaminate drinking water, although that’s not the only hazard from the practice known as fracking, said Fred Baldassare, senior geoscientist at Echelon Applied Geoscience.
