Why Geneva Has High Radon Risk
Geneva is located in Kane County, classified by the EPA as Radon Zone 1 — the highest predicted indoor radon designation. The county average indoor radon level is approximately 4.6 pCi/L, exceeding the EPA action level. About half of homes tested return results above the threshold. The Fox River Valley geology — dolomite and limestone bedrock rich in naturally occurring uranium — drives radon production beneath Geneva’s homes.
With median home prices in the $461,000–$525,000 range and 400 to 525 annual home sales, Geneva is an active market where radon testing is standard in virtually every transaction. Elevated results are common, making mitigation one of the most frequent outcomes of home inspections in the Fox Valley.
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
Under the Illinois Radon Awareness Act (420 ILCS 46), sellers must provide buyers with the IEMA radon pamphlet and disclosure form, plus any known test results. In Kane County where half of homes test elevated, this disclosure triggers testing in virtually every transaction. As of January 2024, the Tenant Radon Protection Act requires disclosure for most residential leases. All radon professionals must hold an active IEMA license (420 ILCS 44).
How Radon Mitigation Works
Sub-slab depressurization is the standard — a PVC pipe and fan system pulling radon from beneath the foundation. Given Kane County’s elevated levels, some Geneva homes may need multiple suction points. Most installations take 4–8 hours. Systems reduce radon by up to 99%. See our radon mitigation guide.
