What IEMA's radon test records show for Westmont

IEMA publishes radon results reported by licensed measurement professionals. For test addresses in Westmont, we counted 1,394 valid tests on homes without a mitigation system; 38% were at or above EPA's 4.0 pCi/L action level and 15% 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 Westmont is below 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 Westmont and what it means for radon

About 24,429 people lived in Westmont in the 2020 Census. The median home there was built around 1976, and the biggest share of its housing went up between 1970 and 1989 (32% before 1970, 43% from 1970–1989, 21% from 1990–2009, 3% since 2010). Roughly 41% of homes are detached single-family houses and 8% are townhouses or other attached single-family homes; about 55% of households own their home.

Most homes here are conventional basement or slab houses, which are typically mitigated with sub-slab depressurization: a sealed pipe from under the slab to a fan that vents above the roofline, per EPA's guidance.

Next steps in Westmont

  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.
