Gas Drilling in Upstate New York -- Is drinking water being affected?

As many of you probably know, upstate New York houses much of the drinking water that is consumed in NYC.
The Cannonsville Reservoir, pictured below, is located less than ten minutes from the house I grew up in in Hancock, NY (Delaware county), and provides NYC with about 50% of its drinking water (Wikipedia.org).

Currently, hearings are under way in which the possibility of hydraulic fracturing ("fracking," a specific technique for drilling natural gas) in New York state is being discussed. The EPA argues that the gas drilling procedures are environmentally friendly, while critics are claiming that the technology is flawed. Fear lies in the possibility that natural gas may contaminate drinking water. Read all about the proceedings.
