Hydraulic fracturing (commonly "hydrofracking" or just "fracking") is the injection of water and chemicals under high pressure into rock formations to extract natural gas. A study by the New York Times in early 2011 revealed that the wastewater, which can total more than 1 million gallons per drilling and can contain corrosive salts and carcinogens, often contains high levels of radioactive material and is inadequately treated before discharge into rivers that supply drinking water. Communities in Upstate New York such as here in Otsego County are mobilising against fracking. There is concern that fracking could contaminate the drinking water of New York City with carcinogenic chemicals.
