On January 15, I posted a link to a report of the gas explosions that occurred in the vicinity of recent gas well drilling into the Marcellus shale in Susquehanna County, PA. At that time, the PA Department of Environmental Protection (DEP) was collecting gas samples to determine the source of the gas. According to the Gannett news service, “Tests show gas found in water is “production gas” … meaning it escaped from the kind of geological formation commonly tapped for energy. The state has ruled out the possibility it was a product of organic conditions in shallow ground that sometimes affect water wells.” So far, gas has only been found in water supplies and not in basements. Further analysis is needed to determine how the gas migrated from the shale thousands of feet below the water wells.
