Separating fracking facts from fiction
Opinion Journal:
...There is much more.
• 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.
The Duke study did spotlight a long-known and more legitimate concern: the possibility of leaky well casings at the top of a drilling site, from which methane might migrate to water supplies. As the BP Gulf of Mexico spill attests, proper well construction and maintenance are major issues in any type of drilling, and they ought to be the focus of industry standards and attention. 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. States like Wyoming and Pennsylvania require companies to publicly disclose their chemicals, Texas recently passed a similar law, and other states will follow.
Drillers must dispose of fracking fluids, and environmentalists charge that disposal sites also endanger drinking water, or that drillers deliberately discharge radioactive wastewater into streams. The latter accusation inspired the EPA to require that Pennsylvania test for radioactivity. States already have strict rules designed to keep waste water from groundwater, including liners in waste pits, and drillers are subject to stiff penalties for violations. Pennsylvania's tests showed radioactivity at or below normal levels.

What is really scary for opponents of fracking is the availability of inexpensive energy from natural gas and oil domestically produced. They have planned on driving up the cost of energy to make their preferred alternatives look more reasonably priced. With affordable natural gas available with its low emissions it kind of messes up their market manipulation game. They are really disappointed by low priced energy alternatives.
