Radon Testing & Mitigation in Menomonie, WI
Radon work in Menomonie covers downtown craftsmans on Main Street, the homes ringing Lake Menomin, the UW-Stout area rentals, and the rural properties out toward Knapp and Downsville. Dunn County is EPA Zone 1. Lake-side and river-bottom homes often have higher water tables that change the mitigation approach slightly.

What's typical here
Lake-side and river-bottom Menomonie homes often have higher water tables — meaning the soil under the slab can be saturated for parts of the year. The fix is usually a sealed sump-cover suction point rather than a slab-core point, because a sealed sump is already where moisture exits and adapts well as a radon-system suction point. See sub-slab depressurization for system anatomy.
UW-Stout area rentals
A lot of the housing stock around UW-Stout is older single-family homes converted to student rentals. These properties often have deep, cold basements with stone walls and never-tested radon levels. Landlord-initiated long-term testing is the cheapest approach; mitigation, when needed, costs the same as it does for owner-occupied homes.

Frequently asked questions
Is Menomonie an EPA Zone 1 area?
Yes — Dunn County is EPA Zone 1, the highest predicted radon zone. Local data shows about 1 in 3 Menomonie homes test above 4.0 pCi/L, with rental properties near UW-Stout sometimes showing higher because they're often older houses with deep basements that don't get tested otherwise.
Are college rentals near UW-Stout tested?
Many aren't. Wisconsin doesn't require radon testing in rental units, though some landlords do it voluntarily. Tenants concerned about radon can have a short-term test placed and the report sent directly to them.
How does the lake-side geology affect mitigation?
Homes near Lake Menomin and Tainter Lake often have higher water tables, which can affect sub-slab suction performance. Sealed sump pits are the most common adaptation — the sump becomes part of the radon system, with a gasketed lid and a sealed discharge.
