Craig and Julie Sautner moved to Dimock from a nearby town in March 2008. They were in the process of renovating their modest but beautifully situated home on tree-canopied Carter Road when land men from Houston-based Cabot Oil & Gas, a midsize player in the energy-exploration industry, came knocking on their door to inquire about leasing the mineral rights to their three and a half acres of land. The Sautners say the land men told them that their neighbors had already signed leases and that the drilling would have no impact whatsoever on their land. (Others in Dimock claim they were told that if they refused to sign a lease, gas would be taken out from under their land anyway, since under Pennsylvania law a well drilled on a leased piece of property can capture gas from neighboring, unleased properties.) They signed the lease, for a onetime payout of $2,500 per acre—better than the $250 per acre a neighbor across the street received—plus royalties on each producing well.

Drilling operations near their property commenced in August 2008. Trees were cleared and the ground leveled to make room for a four-acre drilling site less than 1,000 feet away from their land. The Sautners could feel the earth beneath their home shake whenever the well was fracked.

Within a month, their water had turned brown. It was so corrosive that it scarred dishes in their dishwasher and stained their laundry. They complained to Cabot, which eventually installed a water-filtration system in the basement of their home. It seemed to solve the problem, but when the Pennsylvania Department of Environmental Protection came to do further tests, it found that the Sautners’ water still contained high levels of methane. More ad hoc pumps and filtration systems were installed. While the Sautners did not drink the water at this point, they continued to use it for other purposes for a full year.

“It was so bad sometimes that my daughter would be in the shower in the morning, and she’d have to get out of the shower and lay on the floor” because of the dizzying effect the chemicals in the water had on her, recalls Craig Sautner, who has worked as a cable splicer for Frontier Communications his whole life. She didn’t speak up about it for a while, because she wondered whether she was imagining the problem. But she wasn’t the only one in the family suffering. “My son had sores up and down his legs from the water,” Craig says. Craig and Julie also experienced frequent headaches and dizziness.

By October 2009, the D.E.P. had taken all the water wells in the Sautners’ neighborhood offline. It acknowledged that a major contamination of the aquifer had occurred. In addition to methane, dangerously high levels of iron and aluminum were found in the Sautners’ water.

The Sautners now rely on water delivered to them every week by Cabot. The value of their land has been decimated. Their children no longer take showers at home. They desperately want to move but cannot afford to buy a new house on top of their current mortgage.

“Our land is worthless,” says Craig. “Who is going to buy this house?”

As drillers seek to commence fracking operations in the Delaware River basin watershed and in other key watersheds in New York State—all of which sit atop large repositories of natural gas trapped in shale rock deep underground—concerned residents, activists, and government officials are pointing to Dimock as an example of what can go wrong when this form of drilling is allowed to take place without proper regulation. Some are pointing to a wave of groundwater-contamination incidents and mysterious health problems out West, in Colorado, New Mexico, and Wyoming, where hydraulic fracturing has been going on for years as part of a massive oil-and-gas boom, and saying that fracking should not be allowed at all in delicate ecosystems like the Delaware River basin.
