PITTSBURGH – The U.S. Environmental Protection Agency said Wednesday that it has completed tests on drinking water in the northeastern Pennsylvania village of Dimock and has determined it is safe to drink, despite residents’ claims it has been polluted by gas drilling.

The EPA said in a statement that it doesn’t plan further tests, and that there’s no need to provide residents with alternative supplies of drinking water.

Dimock resident Ray Kemble didn’t accept the EPA verdict.

“I don’t care what EPA says. The water is still polluted,” Kemble said. “Do something about it.”

The town became a focus in the debate over hydraulic fracturing, or fracking, when opponents of drilling showed that some residents were able to light their tap water on fire because of high levels of methane gas. Geologists say such contamination can also happen naturally.

Some Dimock residents and anti-drilling groups claimed that Houston-based Cabot Oil & Gas Corp. polluted the local aquifer with methane and chemicals. They disputed earlier EPA findings that the water was safe.

State environmental regulators previously determined that Cabot contaminated the aquifer underneath homes in Dimock with explosive levels of methane, although they later determined the company had met its obligations under a consent agreement and allowed Cabot to stop delivering bulk and bottled water last fall.

Another Dimock resident said EPA’s public statements are different from what the agency tells the homeowners in private.

“They recommended that we don’t drink or use the water, but told us they can’t go public with that,” said Scott Ely, who added that he plans to proceed with a lawsuit against Cabot.

Cabot said in a statement that the tests confirm that the contaminants don’t pose a threat to human health or the environment, and that its operations in Dimock “have led to significant economic growth in the area, marked by a collaborative relationship with the local community. Cabot will continue to cooperate with federal, state and local officials in using the best and most accurate science to address public concerns.”

Kathryn Klaber, president of the Marcellus Shale Coalition, an industry group, said the EPA findings mean “we’re now able to close this chapter once and for all.”

Shale gas drilling has attracted national attention because advances in technology have unlocked billions of dollars of gas reserves, leading to a boom in production, jobs and profits, as well as concerns about pollution and public health. The gas is freed through fracking, in which large volumes of water, plus sand and chemicals, are injected to break the rock apart.
