USGS Fracking Study Confirms Methane Contamination of Drinking Water in Pavillion, Wyoming

For those concerned about the future of shale gas development in the U.S., water contamination present in a monitoring well in Wyoming is about to become the lynchpin in the debate over unconventional gas production and the threat fracking poses to drinking water.

The United States Geological Survey (USGS) just released a report confirming the EPA's December 2011 findings that water in Pavillion, Wyoming contains contaminants related to fracking
 
After residents in the region complained of poor water odor and taste, the EPA established two deep water monitoring wells to determine if water quality concerns were related to fracking in the area. 
 
EPA’s analysis of samples taken from the Agency’s deep monitoring wells in the aquifer indicates detection of synthetic chemicals, like glycols and alcohols consistent with gas production and hydraulic fracturing fluids, benzene concentrations well above Safe Drinking Water Act standards and high methane levels. Given the area’s complex geology and the proximity of drinking water wells to ground water contamination, EPA is concerned about the movement of contaminants within the aquifer and the safety of drinking water wells over time.
