DIMOCK, Pa. (AP) – The federal government is back for the first time in more than five years to investigate ongoing claims of contamination in a rural Pennsylvania community that became a battleground in the debate over gas drilling and fracking.

The testing has resurrected old questions about the groundwater in Dimock, whose plight was the focus of the Emmy-winning documentary “Gasland.”

State regulators say Houston-based Cabot Oil & Gas Corp. still hasn’t fixed the water. Cabot says the methane was there long before it began drilling. It’s an argument that’s been going on for eight years.

Public health experts visited 25 homes last month to test for bacteria, gases and chemicals.

Ken Morcom and Kim Grosso say they’re tired of living with tainted water. They’re trying to get Cabot to buy them out.
