The water tables that drinking water is drawn from are thousands of feet shallower than the strata the natural gas comes from and which are hydraulic fractured.

Now any well that's not cased and cemented adequately where the wellbore passes through the water table could contaminate that water table regardless of whether fracing is done.

Drillers have used hydraulic fracturing for decades, but it has been refined and become more commonplace recently as a cost-effective way to draw large quantities of natural gas from the many shale formations throughout the country.

Industry officials say the risks have been exaggerated and that the method often called “fracing” or “fracking” has yet to be directly linked to any incidents of drinking water contamination.

Jeff Smith, chief financial officer of BJ Services, said he appreciates Congress' concern but that it may have the wrong focus.

“It's the casing and cementing of a well that's critical,” Smith said, referring to the thousands of feet of steel pipe and cement that line a gas well. “Not only does it stabilize the well bore, it isolates the gas zone from aquifers so you don't have any migration of fluids or gas.”

The Environmental Protection Agency said in a 2004 report that hydraulic fracturing did not pose a significant threat to drinking water supplies, but the agency is expected to revisit the issue this year.
