SCRANTON — Federal environmental regulators said Thursday that well water testing at 11 homes in a northeastern Pennsylvania village where a gas driller was accused of polluting the aquifer failed to show elevated levels of contamination.

The Environmental Protection Agency, which is sampling well water at dozens of homes in Dimock, Susquehanna County, said initial test results “did not show levels of contamination that could present a health concern.”

Dimock has been at the center of a fierce debate over the environmental and public health impacts of Pennsylvania’s Marcellus Shale drilling industry.

State environmental regulators had previously determined that Houston-based Cabot Oil & Gas contaminated the aquifer underneath homes along Carter Road in Dimock with explosive levels of methane gas. Residents who are suing Cabot assert their water is also polluted with drilling chemicals. Many other residents of Dimock say that the water is clean and that the plaintiffs are exaggerating problems with their wells to help their lawsuit.

The federal environmental agency began testing the water in January, more than a month after the state Department of Environmental Protection allowed Cabot to stop delivering replacement water to about a dozen families.

Dimock resident Scott Ely, who is among the plaintiffs suing Cabot, disputed the EPA interpretation of his test results. He said the results showed a range of contaminants at unsafe levels, including sodium and arsenic.

“We’ve had hundreds of tests done out here, and we’ve had so many different scientists say you have bad water here, there’s not a doubt about it. And yet when the state and feds test our water, they say we can drink it,” said Ely, who plans to meet with the EPA to review the test results. “Absolutely not.”

Cabot said in a statement that it is pleased by the EPA test results and that it is “steadfastly committed to environmental stewardship, collaboration with state regulators, and compliance with all applicable federal, state and local laws.”
