Why York County Has High Radon
Local Geology
Sandy coastal soils transition to granite ledge inland. Coastal York has Maine's lowest radon averages but inland still presents real risk.
Housing Stock
Mix of historic seasonal homes converted to year-round, dense Sanford-Springvale neighborhoods, and growing exurban subdivisions.
Well Water
Coastal towns are mostly municipal; inland York (Sanford, Berwick, Lebanon, Acton) is heavily on private wells.
Climate Effect
Maine's long heating season creates a strong stack effect that pulls radon out of the soil and into homes — winter readings in York County typically run 30–50% higher than summer.
