Why Elmhurst Has Elevated Radon Risk
Elmhurst is in DuPage County where the average indoor radon level is approximately 4.3 pCi/L, exceeding the EPA action level. With a population of approximately 47,000 and median home prices ranging from $505,000 to $660,000, Elmhurst is a high-value market where homeowners take environmental safety seriously. The glacial till and dolomite limestone beneath the city create natural radon pathways. Nearly all homes have full basements where radon accumulates.
Radon causes approximately 21,000 lung cancer deaths annually — the leading cause among non-smokers. Testing is the only way to know your home’s level.
What Illinois Law Requires for Radon

How Radon Mitigation Works
