EPA probe demands more water testing in Texas

HOUSTON (AP) — The U.S. Environmental Protection Agency was justified in immediately barring residents in North Texas from using water contaminated with explosive methane and cancer-causing benzene, but additional testing and work needs to be done to assess whether a risk still exists, according to an internal investigation released Tuesday.

The report by the federal agency's Office of Inspector General concludes a yearlong probe into a case that has been mired in politics and a persistent back-and-forth between Texas and the EPA over how to oversee oil and gas drilling operations. It also left residents in the affected area either using the same water wells or paying to truck in water from other sources.

But the report's findings could reopen the door to a case that appeared to have been closed in 2012, when the EPA settled with Range Resources, the gas driller it suspected had contaminated the water, and withdrew its emergency actions.

Now, the EPA is being asked to evaluate Range Resources' most recent tests for quality and determine whether there are still risks to public health or of explosions due to methane gas. The report also asked the EPA to work with the Texas Railroad Commission — the state agency that oversees oil and gas operations — to mitigate any problems.

"Although EPA officials believe that current residents are not presently at risk, the overall risk faced by current and future area residents has not been determined," the report states. "We believe that the EPA needs to implement cost-effective steps to better gauge the risk and document and disseminate its findings to affected residents."

This story began in 2010 when Steve Lipsky, a resident of Weatherford, an upscale suburb about 65 miles west of Dallas, noticed his water bubbled like champagne. He alerted the Railroad Commission, then eventually the EPA when he felt the state was not responding quickly enough.

The EPA took its own tests, including isotopic fingerprinting designed to determine the origin of the gas and other chemicals, and decided Range Resources' nearby drilling operations were the most logical culprit. The agency found that the gas in the water and the gas at Range's drilling operation were nearly identical, and that the levels of contamination in the residential wells were alarming.

It filed an emergency order in December 2010, demanding that Range Resources immediately supply the impacted families with water, determine the origin of the contamination and mitigate the problem. The agency believed that methane gas and other chemicals leaked into the aquifer through the company's nearby hydraulic fracturing, a method to extract natural gas or oil by pumping high-pressure, chemical-laced water to crack thick layers of rock.
