Buried Secrets: Is Natural Gas Drilling Endangering U.S. Water Supplies?

In July, a hydrologist dropped a plastic sampling pipe 300 feet down a water well in rural Sublette County, Wyo., and pulled up a load of brown oily water with a foul smell. Tests showed it contained benzene, a chemical believed to cause aplastic anemia and leukemia, in a concentration 1,500 times the level safe for people.

Sublette County is the home of one of the nation's largest natural gas fields, and many of its 6,000 wells have undergone a process pioneered by Halliburton called hydraulic fracturing, which shoots vast amounts of water, sand and chemicals several miles underground to break apart rock and release the gas. The process has been considered safe since a 2004 study (PDF) by the Environmental Protection Agency found that it posed no risk to drinking water. After that study, Congress even exempted hydraulic fracturing from the Safe Drinking Water Act. Today fracturing is used in nine out of 10 natural gas wells in the United States.

The EPA’s regional office in Denver sharply disagreed. But because it has only an advisory role in the federal review process, and hydraulic fracturing is exempted from the Safe Drinking Water Act, there was little the EPA could do. It rebuked the BLM in a strongly worded letter and gave the development plans in Sublette County a rare "unsatisfactory" rating. It also recommended that the project be stopped until further scientific study could be done.

Buried deep within the 424-page report are statements explaining that fluids migrated unpredictably -- through different rock layers, and to greater distances than previously thought -- in as many as half the cases studied in the United States. The EPA identified some of the chemicals as biocides and lubricants that “can cause kidney, liver, heart, blood, and brain damage through prolonged or repeated exposure." It found that as much as a third of injected fluids, benzene in particular, remains in the ground after drilling and is “likely to be transported by groundwater."

1. Is it? Of course. And that would be part of the plan. To ruin our

public water supplies so they can force us to BUY water to drink.
