Radon and Dunn County homes

Menomonie sits on the Red Cedar River and Lake Menomin and is home to UW-Stout, so it has a mix of older houses near downtown, student rentals and newer homes on the edges of town. Around Colfax, Boyceville and Elk Mound, it's mostly farms and rural homes, many on private wells.

Rentals and older homes

Older Menomonie houses often have fieldstone or block basements with sump pits and cracks, which give soil gas a way in. Sealing those openings is part of a radon fix. Landlords who fix a rental can retest to show tenants the level dropped.

Rural homes and wells

If you're on a private well, radon can be in the water as well as the air. Most of a home's radon comes from soil gas, which an air test measures, so start there and ask the contractor about water.
