Radon mitigation in Delaware
What Delaware homes mean for radon mitigation
Delaware's pre-1950 downtown near Ohio Wesleyan sits on older limestone and block basements with masonry walls that admit soil gas through the wall itself as much as through a slab crack. The newer subdivisions ringing downtown are on poured basements with sumps, a more straightforward sub-slab suction candidate. Glacial till across Delaware County keeps both halves of the city inside EPA Zone 1, so the split is about mitigation routing, not about whether elevated readings occur.
Delaware sits directly on the Olentangy River, with Delaware Dam and Delaware Lake just north of downtown holding back the river's upper watershed.
