(Undated) -- Natural Gas drilling companies in the Marcellus Shale formation are required by Pennsylvania to provide information about what chemicals are used in the hydraulic fracturing process. Fracking, as it's called, involves pumping chemical-laced water deep into the earth. Matt Pitzarella, with Range Resources, speaking on this morning's Radio Smart Talk, said the concerns over the fracking process have been blown out of proportion and he blames the gas industry. "Anyone can see what Range uses. It's on our website. We use about four chemical additives. They collectively make up about 8 one-hundredths of one percent of what it is we inject. The rest of it is water and sand," he says. But Barbara in York called in to voice her skepticism of what she's been told about the fracking process. "I'm very concerned about these gas companies," she says. "They seem very reticent to name the chemicals that they put into the wells." All this month, witf's Real Life Real Issues will focus on the issues surrounding drilling in the Marcellus Shale.
