Illinois radon mitigation license RNM2018212. Manhattan, Will County.
Radon mitigation in Manhattan
Manhattan is Will County all the way through, so start with the county’s $8 radon kit. The Will County Health Department sells it in Joliet, Bolingbrook, and Monee, and the $8 already covers the lab and the report. A detector you can reuse is the other cheap way in.
Text Bill the number and he’ll tell you what it means, free. A high result gets a visit: Bill looks at the foundation and the builder pipe, if there is one, and gives you the price. Manhattan is a short drive past New Lenox for us, and new-system work is usually scheduled within a week or two.
A newer Manhattan home is not a low home
Manhattan has plenty of homes built after the Radon Resistant Construction Act, 420 ILCS 52, took effect on June 1, 2013, and plenty from before it. Age is not in the IEMA city total, so this page does not invent a share of new homes. What the law gave those newer homes is a passive pipe and nothing on it. A test still decides whether the fan gets added.
Manhattan’s small set, and why it matters anyway
Manhattan is the smallest Will County set on this site. The IEMA layer holds 195 valid Manhattan tests with no mitigation system recorded (our count, 14 October 2026). The median is 3.6 pCi/L and 47.7% landed at or above 4.0.
Will County as a whole is 44.9% at or above 4.0 from 27,611 tests, with a median of 3.5. Manhattan’s share is a bit higher and its count is much smaller, so the percentage can move as tests are added. It is context for the village, not a reading for your home.
Just under half
Read the number the simple way: of the 195 Manhattan tests on file, just under half came back at the EPA action level or above, and the typical result, 3.6, sits in the range where EPA says to consider a fix. New Lenox to the north and Shorewood are the only towns on this site with a higher median. Manhattan homes with a basement and a sump get the same look as a New Lenox home; the difference is that Manhattan’s file is one tenth the size, so one more year of tests could move its share several points either way.

Manhattan questions
Is 195 tests enough to describe Manhattan?
It is enough to publish, and too small to treat as a stable average. The median is 3.6 pCi/L and 47.7% of those 195 tests were at or above 4.0. Your home still needs its own test.
Do you schedule Manhattan with New Lenox?
Manhattan is on the same roads as our New Lenox work, so it fits the route. New-system work is usually scheduled within a week or two. Tell Bill the address and any closing date when you call.
Where can I get a radon test kit in Manhattan?
From the Will County Health Department, for $8, at any of its three offices: Joliet, Bolingbrook, or Monee. The lab and the report are part of the $8. A reusable detector is the other cheap way to get a Manhattan number.
The test came back low. Does the passive pipe need anything?
No. Leave it as it is. Test again every few years, or keep a detector running, and that is all the attention it needs.
