Why Sagadahoc County Has High Radon
Local Geology
Compact county sitting on uniformly high-uranium granite. Almost every home tests above background.
Housing Stock
Historic Bath shipbuilding-era homes with stone foundations, plus modern Topsham subdivisions — both produce frequent action-level readings.
Well Water
Bath and Topsham have municipal water; outlying towns (Bowdoinham, Bowdoin, Phippsburg, Arrowsic) are 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 Sagadahoc County typically run 30–50% higher than summer.
