Why Androscoggin County Has High Radon
Local Geology
Granite bedrock from the western mountain foothills extends through the county. The Androscoggin River valley channels radon through fractured ledge.
Housing Stock
Dense Victorian-era and triple-decker housing in Lewiston-Auburn, with stone foundations that allow easy radon entry. Rural areas have newer construction on rural lots.
Well Water
Mixed — Lewiston-Auburn is municipal, but rural Androscoggin (Greene, Sabattus, Lisbon) is heavily on 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 Androscoggin County typically run 30–50% higher than summer.
