Why Ellendale homes especially need radon testing.
Steele County sits squarely in the elevated-radon zone the Minnesota Department of Health has mapped across southern Minnesota. Roughly 2 in 5 Minnesota homes test above the EPA action level of 4.0 pCi/L, and the older basement and slab construction common in Ellendale only increases the risk. The good news: testing is fast, mitigation is straightforward, and most Ellendale buyers can resolve a high reading before closing.
