The Department of Environmental Protection is continuing to investigate the source of stray methane gas detected in the Susquehanna River and at six private water wells in Wilmont Township, Bradford County, late last week. "Chesapeake Energy has been working at the direction of DEP to determine the source or
sources of the stray gas," said DEP Secretary John Hanger.
"Gas migration is a serious, potentially dangerous problem. Chesapeake must stop the gas from migrating."
Chesapeake has six Marcellus Shale gas wells located on the Welles well pads one three and four, located two to three miles northwest of the Susquehanna River. These wells are believed to be the source of stray gas that was detected on August 4 at a residence located on Paradise Road in Terry Township.

DEP issued a notice of violation to Chesapeake and required it to provide and implement a plan to remediate. Progress has been made, but, to date, this violation has not yet been fully resolved. While neither DEP nor Chesapeake have been able to conclusively show that the Welles wells are the source, DEP believes that they are the most likely source.

The wells were drilled between Dec. 2009 and March of this year; however the wells have not been fractured or "fracked" and are not producing Marcellus gas. For that reason, DEP believes that any stray gas migrating from these wells is not from the Marcellus Shale formation, but from a more shallow rock formation.

Chesapeake has screened 26 residences within a one-half mile radius of the river and found six water wells to have elevated levels of methane. Chesapeake monitored each of the houses served by an impacted water well and found no indication of methane gas in the homes.
On September 3, high levels of methane were detected in the crawl space under a seasonal residence. Emergency responders were contacted to ventilate below the home and gas and electric utilities were shut off to eliminate any potential for ignition.
Chesapeake has equipped water wells with high levels of methane with ventilation systems and installed five methane monitors in the homes associated with the impacted wells. Additionally, Chesapeake has provided potable water to the effected residents. No residents have been evacuated from their homes.

DEP first received information about water bubbles in the Susquehanna River late  on September 2, with additional reports received the next morning of bubbling in two private drinking water wells nearby. In response, DEP sent two teams of inspectors to investigate the source of stray methane gas on September 3.
One team of DEP inspectors went to the Susquehanna River near to Sugar Run where bubbling had been reported. DEP collected samples of the gas for isotopic analysis which is used to identify the source. Analysis of the lab results will be complete within 2 weeks.

Biogenic methane gas is formed at shallow depths from the natural organic decomposition of waste, such as one would find in swamp gas. Thermogenic methane gas is produced in deeper geologic formations and is the gas typically developed for economic purposes.

Both DEP and Chesapeake have taken gas samples from the water well heads and the natural gas wells. The results will help to determine if the source of the stray gas detected at the river and in the water wells is the Welles wells.

Anyone who notices unusual bubbling in surface or well water should notify DEP immediately by calling 570-327-3636.

What a fabulous blog! As you may know, Catskill Mountainkeeper in Sullivan County and Catskill Heritage Alliance in Ulster/Delaware Counties of NY are working to stop fracking in NY and to educate people to the harm drilling causes. It's not enough to just not frack in the Watershed...we all deserve clean water!

We support your fight and I am spreading word of your blog.

Thank you for your are not alone!

Where can one find anti-fracking lawn signs (short and sweet ones) and the No Drilling bumper stickers? Thanks.

Your non-scientific fears are not substaniated with regard to preexisting methane gas conditions. Why not support the efforts made by companies like Chesapeake that actually care and employee many local citizens. I have friends that work for Chesapeake and other contractors associated with clean/effective/safe gas extraction. Do you want to contribute to the massive unemployment in this country (largely in part as a result of a socialist, oil & gas industry hating, government growing, Muslim supporting President) I plan to take a job with a Chesapeake affiliate soon and would like to earn above $7.00/hour for once! Please reconsider your non American approach. We do wish energy independance from those foreign (Muslim) countries that would like nothing more than to destroy us. Get a life and start to support Gas Drilling in this area.

Chesapeake cares? Cares about what? Profits maybe? Did you realize that, when a gas worker gets injured, that person is not allowed to seek medical help at a local hospital? He must be treated by gas company medical personnel. Why do you suppose that is? Do you realize that much of the natural gas produced in this country will be sold overseas? This has nothing to do with energy independence. Gas corporations cannot get enough money for their gas in the US. They will sell to China and other foreign countries. I cannot do what you ask: to support gas drilling. I wish you the best in the future working for the gas industry. Be safe. Yours is an extremely dangerous and deadly industry. One more thing: natural gas is at least as bad as coal in causing global warming. Methane is worse than carbon dioxide. Inspite of what people say, natural gas drilling is a very, very dirty process when you look at the complete cyle.
