COLORADO - EPA Map of Radon Zones The purpose of this map is to assist National, State and local organizations to target their resources and to implement radon-resistant building codes. This map is not intended to determine if a home in a given zone should be tested for radon. Homes with elevated levels of radon have been found in all three zones. All homes should be tested, regardless of zone designation. http://www.epa.gov/radon/zonemap.html MOFFAT JACKSON SEDGWICK LARIMER ROUTT LOGAN WELD PHILLIPS GRAND RIO BLANCO MORGAN BOULDER GILPIN.
