The Pennsylvania Department of Environmental Protection (DEP) has concluded that Schreiner Oil and Gas Company is the entity responsible for gas migration and water supply issues in McKean County, according to this DEP press release. It reasoned: “Schreiner has been actively drilling combination oil and gas wells in the area since last fall and did not establish background water quality in the area prior to drilling. Therefore, Schreiner is presumed responsible for restoring water supplies within 1,000 feet of the drill sites.”
