PAVILLION, Wyo. (AP) — A Wyoming state study has found no air quality problems near Pavillion's natural gas field after more than a year of testing.
The Casper Star-Tribune reports (http://tinyurl.com/8h8wuqs ) the Department of Environmental Quality used a monitoring station near the field owned by Encana Oil and Gas. It measured nitrogen oxides, hydrocarbons, particulate matter and ozone.
The study said no results exceeded standards set by the U.S. Environmental Protection Agency.
The state and the EPA are also investigating whether natural gas drilling at the field contaminated several water wells in the area.
