NORTH DAKOTA - 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 DIVIDE BURKE BOTTINEAU RENVILLE ROLETTE CAVALIER PEMBINA TOWNER WILLIAMS WALSH MCHENRY PIERCE RAMSEY WARD BENSON GRAND FORKS NELSON MCKENZIE MCLEAN EDDY SHERIDAN WELLS MERCER DUNN FOSTER GRIGGS STEELE BILLINGS OLIVER GOLDEN VALLEY BURLEIGH KIDDER STUTSMAN STARK BARNES CASS MORTON SLOPE HETTINGER LOGAN LA MOURE RANSOM GRANT EMMONS BOWMAN ADAMS RICHLAND SIOUX MCINTOSH DICKEY SARGENT Zone 1 Zone 2 Zone 3 IMPORTANT: Consult the publication entitled "Preliminary Geologic Radon Potential Assessment of North Dakota" (USGS Open-file Report 93-292-H) before using this map. See http://energy.cr.usgs.gov/radon/grpinfo.html This document contains information on radon potential variations within counties. EPA also recommends that this map be supplemented with any available local data in order to further understand and predict the radon potential of a specific area. ------- |
