Gov. Andrew M. Cuomo's administration announced on Wednesday that it would ban hydraulic fracturing in New York State because of concerns over health risks. Fracking, as it is known, was heavily promoted as a source of economic revival. Mr. Cuomo had once been poised to embrace it. Instead, the move to ban fracking left him acknowledging that, I've never had anyone say to me, 'I believe fracking is great,' " he said. "Not a single person. What I get is, 'I have no alternative but fracking.'" The question of whether to allow fracking ... has been one of the most divisive public policy debates in New York in years. Fracking is occurring in many states. Environmental advocates, alarmed by the growth of the practice, pointed to New York's decision as the first ban by a state with significant natural-gas resources. The acting state health commissioner, Dr. Howard A. Zucker ... found "significant public health risks" associated with fracking. Holding up copies of scientific studies to animate his arguments, Dr. Zucker listed concerns about water contamination and air pollution, and said there was insufficient scientific evidence to affirm the safety of fracking. Dr. Zucker said his review boiled down to a simple question: Would he want his family to live in a community where fracking was taking place? His answer was no. "The potential risks are too great."
