Groundwater and petroleum resources of Sullivan County, Pennsylvania

PDF versionPDF version


Publication Year: 



Sullivan County is largely a rural forested county with a small population that relies almost exclusively on groundwater for its drinking water. Approximately one-third of the county is state forest, park, or game land. The Marcellus natural gas boom has not yet affected the county as much as surrounding areas to the west and north; however, Sullivan County has recently experienced gas drilling beyond any past hydrocarbon exploration. Shale-gas drilling has commenced but little production has occurred because of current low gas prices and a lack of infrastructure in the county. The Marcellus Formation lies about 7,900 feet below the surface in Sullivan County.
