We’ve commented previously on the contamination claims related to Pavillion, WY.  The Casper Star-Tribune has an update for us:  "Natural gas wells in the Pavillion Gas Field were properly drilled and maintained, but more study is needed to prove if energy operations contaminated drinking water in the region, according to a draft report released by Wyoming regulators Wednesday. *** Those findings were among the conclusions of a preliminary study released by the Wyoming Oil and Gas Conservation Commission. The report is one of three investigations Wyoming is conducting into polluted drinking water near the town of Pavillion. The state is also reviewing disposal pits and testing water quality in the area. All three investigations will be combined in a final report."
