Fracking

"Absence of proof is not proof of absence -- that's not good science," says Geoffrey Thyne, a geology professor at the Colorado School of Mines, based in Golden. As Garfield County's geological expert, he speaks in steadied tones. "There's a real dearth of baseline information. I don't think any fracking expert would tell you that we are 100 percent sure where the fractures go. No one has studied how often there are lateral leaks into nearby aquifers. People out here kind of figure that the government is looking out for them, and if there was a real problem, some expert would come forward and say so. Unfortunately, because no one's studying this, it might be a while."

I suspected the natural gas boom would be a nightmare for local water supplies. It is.
