People gather on the steps of New York City Hall protesting the states plan for shale oil drilling in the city's watershed in New York January 4, 2010. Last week, the U.S. Environmental Protection Agency said it had "serious reservations" about allowing shale gas drilling in New York City's watershed, warning of a threat to the drinking water for 9 million people.The drilling process known as hydraulic fracturing, or "fracking," involves blasting through rock with a mixture of water, sand and a proprietary list of chemicals used to split the shale formation and free trapped gas.
