"The U.S. Environmental Protection Agency said for the first time it found chemicals used in extracting natural gas through hydraulic fracturing in a drinking-water aquifer in west-central Wyoming.
Samples taken from two deep water-monitoring wells near a gas field in Pavillion, Wyoming, showed synthetic chemicals such as glycols and alcohols “consistent with gas production and hydraulic-fracturing fluids,” the agency said today in an e- mailed statement."
