Why Penobscot County Has High Radon
Local Geology
Glacially scoured granite ledge dominates the region. Many homes are built directly on or near exposed bedrock.
Housing Stock
Older Bangor-area homes plus rapidly growing rural subdivisions in Hampden, Hermon, and Glenburn. Mix of tight modern builds and porous older foundations.
Well Water
Outside Bangor and Brewer, almost everyone is on a private well. Water radon levels in Penobscot County routinely exceed 5,000 pCi/L.
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 Penobscot County typically run 30–50% higher than summer.
