In an article about natural gas drilling ("Md. environment chief wants more U.S. oversight of fracking," April 13), The Sun's John Fritze reports that to "extract natural gas through fracking, companies use millions of gallons of liquids," but that explanation is inadequate. Anyone interested in information about fracking for gas extraction should watch the HBO documentary, "Gasland," or drive up to Bradford County, Penn. and see the devastating results of this process.
Toxic chemicals are pumped into the ground with water and sand to force the gas up. Sixty-five of the chemicals used are considered dangerous to human health. Water buffalos sit on properties where the wells have been contaminated with methane and other toxic substances. Some homes must be "vented out" when the methane inside becomes dangerously high. Property values of homes with contaminated wells have plummeted in Bradford County. Tanker trucks carrying water to the gas extraction sites and removing the contaminated water for disposal travel 24/7 through the area.
