Environmentalists aren't the only ones who want to know the effects of hydraulic fracturing, or fracking, on water quality. The drilling process pumps water and chemicals into shale rock deep underground to extract natural gas. Some worry those chemicals could make their way into local water supplies. A Pennsylvania group called the Shale Network, gathered recently to pool data on samples gathered from water wells and streams in drilling areas. WPSU intern Lauren Ostberg has the story.
