The ground under Owen Township
North-central Illinois, where Winnebago County sits, is built on Ordovician and Silurian dolomite and limestone, covered by glacial till and outwash from the last Ice Age. That bedrock and cover combination is why the EPA rates the whole county Radon Zone 1, its highest-potential classification, with predicted average indoor screening levels at or above 4.0 pCi/L.
