Halliburton and the Independent Petroleum Association of America, as well as the Cheney/Bush Administration, have given this their seal of approval. And you know the State of Texas ain't going to let the drillers push you around.

"Generally, the Environmental Protection Agency regulates anything that could affect underground drinking water supplies. But in 2005, the industry successfully lobbied for the exemption for fracking from the Safe Drinking Water Act. That leaves regulation up to the states, which don't have the kind of resources the EPA does.

"We have no evidence that hydraulic fracturing is causing problems," says Lee Fuller, vice president of government relations for the Independent Petroleum Association of America. Without evidence of problems, he says there's no reason to pile on more regulation."

"But environmental groups are lobbying Congress to get that exemption overturned as hydraulic fracturing becomes increasingly common. Halliburton, which pioneered hydraulic fracturing, says about 35,000 wells are fracked each year."
