Strict Regulations Needed To Protect Marcellus Shale Regions

By Theodora Filis Responding to an investigative article published by The New York Times, on February 26, 2011, on the high incidence of radioactive materials and other contaminants in the wastes produced from natural gas extraction, Rep. Edward J. Markey (D-Mass.) questioned the Environmental Protection Agency (EPA) on its oversight of these extractive practices. The New York Times found that upon completion of drilling, gas companies dispose of the used hydraulic fracturing water at municipal wastewater plants that are incapable of filtering the naturally existing radioactive substances that are dug up and mixed in with fracturing water in the drilling process. The end result is waste-water plants releasing treated water into rivers and other waterways that are public sources of drinking water as well as fish that are used for food. “ These disturbing revelations raise the prospect that natural gas production has turned our rivers and streams into this generation’s ‘Love Canals,...

Are We Fracking Around With Our Drinking Water?

By Theodora Filis Actor Mark Ruffalo, inadvertently, increased the public's awareness of hydraulic fracturing when Pennsylvania's Office of Homeland Security placed him on a terror watch list while he was promoting “Gasland” a documentary by Josh Fox, on the purported dangers of hydraulic fracturing or “fracking”. Fracking is currently used in 90 percent of the nation’s natural gas and oil wells. The practice makes drilling possible in areas that 10 to 20 years ago would not have been profitable. Fracking involves injecting water, sand, and a cocktail of chemicals at high pressure into rock formations thousands of feet below the surface. This opens existing fractures in the rock and allows gas to rise through the wells. Many of the chemicals used in shale gas drilling, such as benzene, are hazardous. Long-term exposure to such chemicals can have serious health consequences. Because the federal Energy Policy Act of 2005 exempted hydraulic fracturing from regulation under...
