Radon from river-valley soil
The soils under Biscay near the South Fork Crow River release radon that seeps up through foundation cracks and sump pits into basement living space.

Radon is an invisible, odorless gas that seeps up from the soil into Biscay basements. Minnesota is one of the highest-radon states in the country, and the only way to know a home's level is to test it. A 48-hour test gives you the answer before closing.

We place a calibrated continuous radon monitor in the lowest livable level of the Biscay home — usually the basement — and let it sample the air for at least 48 hours under closed-house conditions. The monitor logs hourly readings and reports an average compared to the EPA action level of 4.0 pCi/L.
Radon is invisible and a standard 120-point inspection can't measure it without a monitor, which is exactly why it's worth testing before you close on a Biscay home. Learn more about radon testing or about home inspection in Biscay, MN.

Biscay is a tiny McLeod County village above the South Fork of the Crow River, just six and a half miles southeast of Hutchinson, with modest older houses and manufactured homes on low Crow River ground. The Minnesota Department of Health estimates more than two in five Minnesota homes have radon above the action level — and McLeod County is no exception.
