Radon Mitigation in Stevens Point, WI
Stevens Point anchors central Wisconsin, a University of Wisconsin campus town set on the sandy central-sands plain along the Wisconsin River. Portage County is Radon Zone 1, the higher of the two EPA categories that apply in Wisconsin (predicted average indoor level at or above 4 pCi/L). Radon is a naturally occurring radioactive gas that seeps up out of the soil, and because a large share of area homes sit on private wells, it can also reach indoor air through well water. Whether a cold-weather reading just came back high or you are getting ahead of a home sale, Badger State Radon connects Stevens Point homeowners with independent local radon professionals. We are a free matching service, not a contractor.
Radon in Stevens Point and Portage County
Portage County is EPA Radon Zone 1, the higher of the two EPA categories that apply in Wisconsin (predicted average indoor level at or above 4 pCi/L), cited to the EPA Map of Radon Zones. Stevens Point is a university city with sandy central-sands soils and many homes on private wells, and the zone tells you the countywide screening picture, not your own address. Radon is driven by the ground under a house, so an older near-campus home and a newer build on the edge of town can test very differently, and neighbors can differ too. Statewide, about one in 10 Wisconsin homes is above the action level. You can review area readings on the WI DHS radon results map, but the only way to know your home is to test it.
Radon and private well water in the central sands
Stevens Point sits on the central-sands plain, and many homes here draw drinking water from a private well rather than a municipal system. Radon can dissolve into groundwater and then escape into the air when water is heated or stirred up, during a shower, a load of laundry, or a running faucet. That is a separate pathway from soil gas, and it is specifically a private-well concern, since public systems are treated and monitored. If your home is on a well, the page on radon in water walks through how a water test works and when treatment makes sense.
Testing your Stevens Point home
The regional Radon Information Center serves Portage County, and statewide 17 Radon Information Centers offer kits for about $15 including lab analysis. A short-term charcoal test takes just a few days, which suits a sale timeline, while a long-term test gives a better year-round average. Winter is the peak testing season across central Wisconsin, since closed-up homes let radon build. If a short-term test is at or above 4.0 pCi/L, the EPA recommends confirming with a follow-up test. See radon testing for the full rundown on kits, protocols, and reading a result.
Mitigation and what it costs
When a level comes back high, the common fix is active sub-slab depressurization: a pipe and a continuously running fan that pull radon from under the foundation and vent it above the roofline. Wisconsin DHS estimates a contractor-installed system typically costs $1,000 to $2,000, and Stevens Point homes fall in that range depending on foundation type and system design. Learn how systems work on the radon mitigation page, and the Wisconsin radon guide ties testing, mitigation, and well water together. The independent professionals we match you with can hold the voluntary NRPP or NRSB credentials; we do not perform the work or hold any certification ourselves.
