Radon Mitigation in Baltimore, MD

Radon Mitigation in Baltimore: local conditions

Baltimore, MD sits on clay and coastal plain / piedmont soils and has a humid climate with about 42–46" of precipitation a year. The local water table is higher near the Chesapeake and tidal areas, with moderate winter freeze–thaw cycling, and full basements are common in the piedmont. In practical terms, high rainfall and tidal-area water tables drive seepage and sump demand — which is exactly why radon mitigation is a common need here.
