Safety claims of hydraulic fracking called into question

Many people in southern New York are concerned about a new natural gas drilling project in the Marcellus Shale which involves the controversial procedure known as hydraulic fracking. It's controversial because critics claim that it threatens the drinking water supply. The NYS Department of Environmental Conservation claims that very few problems are associated with fracking but a good investigative piece in the Binghamton Press & Sun-Bulletin seriously calls those claims into question.
