The Facts About Fracking

Editorial from the 6-25/26 WSJ. Excerpts:
"As recently as 2000, shale gas was 1% of America's gas supplies; today it is 25%."

"Today, proven reserves are the highest since 1971, prices have fallen close to $4 and ports are being retrofitted for LNG exports."
Then they attack the myths:
"Fracking contaminates drinking water. One claim is that fracking creates cracks in rock formations that allow chemicals to leach into sources of fresh water. The problem with this argument is that the average shale formation is thousands of feet underground, while the average drinking well or aquifer is a few hundred feet deep. Separating the two is solid rock. This geological reality explains why EPA administrator Lisa Jackson, a determined enemy of fossil fuels, recently told Congress that there have been no "proven cases where the fracking process itself has affected water.""

"A second charge, based on a Duke University study, claims that fracking has polluted drinking water with methane gas. Methane is naturally occurring and isn't by itself harmful in drinking water, though it can explode at high concentrations. Duke authors Rob Jackson and Avner Vengosh have written that their research shows "the average methane concentration to be 17 times higher in water wells located within a kilometer of active drilling sites.""

"They failed to note that researchers sampled a mere 68 wells across Pennsylvania and New York—where more than 20,000 water wells are drilled annually. They had no baseline data and thus no way of knowing if methane concentrations were high prior to drilling. They also acknowledged that methane was detected in 85% of the wells they tested, regardless of drilling operations, and that they'd found no trace of fracking fluids in any wells."
There is "the possibility of leaky well casings at the top of a drilling site, from which methane might migrate to water supplies." "But the risks are not unique to fracking, which has provided no unusual evidence of contamination.."
"Fracking releases toxic or radioactive chemicals. The reality is that 99.5% of the fluid injected into fracture rock is water and sand. The chemicals range from the benign, such as citric acid (found in soda pop), to benzene.""

"...environmentalists charge that disposal sites also endanger drinking water, or that drillers deliberately discharge radioactive wastewater into streams. " but "Pennsylvania's tests showed radioactivity at or below normal levels."

"Fracking causes cancer. In Dish, Texas, Mayor Calvin Tillman caused a furor this year by announcing that he was quitting to move his sons away from "toxic" gases—such as cancer-causing benzene—from the town's 60 gas wells. State health officials investigated and determined that toxin levels in the majority of Dish residents were "similar to those measured in the general U.S. population." Residents with higher levels of benzene in their blood were smokers. (Cigarette smoke contains benzene.)"

"Shale exploration is unregulated. Environmentalists claim fracking was "exempted" in 2005 from the federal Safe Water Drinking Act, thanks to industry lobbying. In truth, all U.S. companies must abide by federal water laws, and what the greens are really saying is that fracking should be singled out for special and unprecedented EPA oversight.

Most drilling operations—including fracking—have long been regulated by the states.
Operators need permits to drill and are subject to inspections and reporting requirements. Many resource-rich states like Texas have detailed fracking rules, while states newer to drilling are developing these regulations."
