Isotech — Stable Isotope Analysis: Determining the Origin of Methane and its Effect on the Aquifer
[Desmogblog article by Steve Horn] DeSmogBlog has obtained a copy of an Obama Administration Environmental Protection Agency (EPA) fracking groundwater contamination PowerPoint presentation describing a then-forthcoming study’s findings in Dimock, Pennsylvania.
The PowerPoint presentation reveals a clear link between hydraulic fracturing (“fracking”) for shale gas in Dimock and groundwater contamination, but was censored by the Obama Administration. Instead, the EPA issued an official desk statement in July 2012 – in the thick of election year – saying the water in Dimock was safe for consumption.
Titled “Isotech-Stable Isotype Analysis: Determinining the Origin of Methane and Its Effets on the Aquifer,” the PowerPoint presentation concludes that in Cabot Oil and Gas’ Dimock Gesford 2 well, “Drilling creates pathways, either temporary or permanent, that allows gas to migrate to the shallow aquifer near [the] surface…In some cases, these gases disrupt groundwater quality.”
Other charts depict Cabot’s Gesford 3 and 9 wells as doing much of the same, allowing methane to migrate up to aquifers to unprecedented levels – not coincidentally – coinciding with the wells being fracked. The PowerPoint’s conclusions are damning.
“Methane is released during the drilling and perhaps during the fracking process and other gas well work,” the presentation states. “Methane is at significantly higher concentrations in the aquifers after gas drilling and perhaps as a result of fracking and other gas well work…Methane and other gases released during drilling (including air from the drilling) apparently cause significant damage to the water quality…”
