EPA Zone 2

Positioned in Ozark County within Missouri's rugged Ozark Mountains region, Isabella sits in EPA Zone 2 where the area's dolomite and limestone karst geology creates moderate radon potential throughout the highlands. Current testing data for this 65676 community is limited, but the region's cave systems and fractured bedrock suggest homeowners should prioritize radon testing.
