The Akron Beacon Journal is reporting that a recent investigation by ODNR has concluded that methane found in drinking water was naturally occurring: "An Ohio state investigation has determined that methane or natural gas in drinking water in northeast Portage County is naturally occurring, not tied to nearby drilling. *** The 25-page report from the Ohio Department of Natural Resources analyzed the well water of Jason and Debby Kline of Nelson Township." It even had Gasland-like complaints of burning tap water: "The Klines complained in December 2012 after Mrs. Kline reported that she had accidentally ignited methane mixed with her tap water while using a candle in the master bedroom."

[Update: For a preliminary study in Carroll County, Ohio, reaching similar findings, see here. "Preliminary results from a study of Carroll County residential wells show that hydraulic fracturing has had no impact on water quality. *** Amy Townsend-Small, assistant professor of geology at the University of Cincinnati, shared findings from the study with members of Carroll Concerned Citizens on Thursday evening."]
