ALLENTOWN, Pa. (AP) — Pennsylvania environmental regulators announced Wednesday they have given permission to a natural-gas driller to stop delivering replacement water to residents whose drinking water wells were tainted with methane.
Cabot Oil & Gas Corp. has been delivering water to homes in the northeast village of Dimock since January of 2009. The Houston-based energy company asked the Department of Environmental Protection for approval to stop the water deliveries by the end of November, saying Dimock’s water is safe to drink.
DEP granted Cabot’s request late Tuesday, notifying the company in a letter released Wednesday morning. Scott Perry, the agency’s acting deputy secretary for oil and gas management, wrote that since Cabot has satisfied the terms of a December settlement agreement requiring the company to remove methane from the residents’ water, DEP “therefore grants Cabot’s request to discontinue providing temporary potable water.”
Residents who are suing Cabot in federal court say their water is still tainted with unsafe levels of methane and possibly other contaminants. Regulators previously found that Cabot drilled faulty gas wells that allowed methane to escape into Dimock’s aquifer. The company denied responsibility, but has been banned from drilling in a 9-square-mile area of Dimock since April of 2010.
Along with its request to stop paying for deliveries of water, Cabot has also asked the department for permission to resume drilling in Dimock, a rural community about 20 miles south of the New York state line where 18 residential water wells were found to be polluted with methane. DEP has yet to rule on that request.
Philip Stalnaker, a Cabot vice president, asserted in a Monday letter to DEP that tests show the residents’ water to be safe to drink and use for cooking, bathing, washing dishes and doing laundry. He said any methane that remains in the water is naturally occurring but that Cabot is willing to install mitigation systems at residents’ request.
Methane is an odorless, colorless, tasteless gas commonly found in Pennsylvania groundwater. Sources include swamps, landfills, coal mines and gas wells. Methane is not known to be harmful to ingest, but at high concentrations it’s explosive and can lead to asphyxiation.
Cabot plans to inform each homeowner by Nov. 1 that it will discontinue deliveries of water by Nov. 30. The company also offered to pay for a plumber to reconnect residents’ water wells.
