"About 65 people, many in jeans, boots and 10-gallon hats, filled Pavillion’s community hall on Aug. 11 to hear the EPA’s findings. They were told that a range of contaminants, including arsenic, copper, vanadium and methane gas were found in the water. Many of these substances are found in various fluids used at drilling sites.
Of particular concern were compounds called adamantanes, a natural hydrocarbon found in gas that can be used to fingerprint its origin, and 2-BE, listed as a common fracturing fluid in the EPA’s 2004 research report on hydraulic fracturing. That compound, which EPA scientists in Wyoming said they identified with 97 percent certainty, was suspected by some environmental groups in a 2004 drilling-related contamination case in Colorado, also involving EnCana.
EPA investigators explained that because they had no idea what to test for, they were relegated to an exhaustive process of scanning water samples for spikes in unidentified compounds and then running those compounds like fingerprints through a criminal database for matches against a vast library of unregulated and understudied substances. That is how they found the adamantanes and 2-BE.
An EnCana representative told the crowd that the company was as concerned about the contamination as the residents were, and pledged to help the EPA in its investigation "
