Polo, IL Radon Facts

EPA Radon Zone Zone 1 — High Risk > 4.0 pCi/L (Zone 1)

County Ogle County, IL

Zip Code 61064

Historic Polo sits in Ogle County within northern Illinois' glacial terrain, where Wisconsin glaciation deposits over limestone bedrock create conditions highly favorable for radon production and accumulation. Testing data for zip code 61064 is currently limited, making home radon testing particularly important given the region's geological risk factors. The area's mix of late-1800s architecture and mid-century homes, most with full basements, provides the below-grade spaces where radon typically concentrates.
