What IEMA's radon test records show for Oswego

IEMA publishes radon results reported by licensed measurement professionals. For test addresses in Oswego, we counted 2,955 valid tests on homes without a mitigation system; 45% were at or above EPA's 4.0 pCi/L action level and 19% were at or above 8.0 pCi/L.

For comparison, 42% of tests were at or above 4.0 pCi/L across the 26 DuPage-area and nearby cities we pulled from the same data, so Oswego is above that average. These are mostly real-estate and homeowner-ordered tests, not a random sample, so they can't predict your house — neighbors on the same block can test very differently. The only way to know is to test your own home.

Housing in Oswego and what it means for radon

About 34,585 people lived in Oswego in the 2020 Census. The median home there was built around 2002, and the biggest share of its housing went up between 1990 and 2009 (8% before 1970, 8% from 1970–1989, 71% from 1990–2009, 14% since 2010). Roughly 72% of homes are detached single-family houses and 18% are townhouses or other attached single-family homes; about 88% of households own their home.

About 14% of Oswego homes were built since 2010. Illinois' Radon Resistant Construction Act has required a passive radon pipe in new homes since June 1, 2013, so a newer house may already have a capped vent pipe. If it tests high, a licensed mitigator can often add a fan to that pipe instead of building a whole new system — usually the cheapest fix.

About 18% of Oswego homes are townhouses or other attached units. If you live in one, check your HOA rules on exterior pipes and fans before you get quotes, and ask whether neighbors have already installed systems.

Next steps in Oswego

  1. If you haven't, run a short-term test in the lowest lived-in level (EPA guidance). For a home sale, use a licensed measurement professional.
  2. If you're at or above 4 pCi/L, get a quote from an IEMA-licensed mitigator — Illinois requires the license for paid mitigation work.
  3. After installation, retest to confirm the level dropped.
