Why South Paris, Maine Has Elevated Radon Risk
The Town of Paris is geologically typical of western Maine — granite and metamorphic rock dominate the subsurface. South Paris village has a dense concentration of older homes with full basements, including Federal and Victorian styles. Paris Hill above has large historic homes that often have stone or fieldstone foundations. Rural roads outside the village centers typically serve homes on private wells, which adds the water radon concern.
- EPA Zone 1 — highest radon potential in the country
- County average radon level: 3.9 pCi/L (EPA action level is 4.0 pCi/L)
- Approximately 1 in 3 homes in this zone test above the EPA action level
- Radon is the #2 cause of lung cancer in the U.S. — responsible for ~21,000 deaths per year
- Most homes can be effectively mitigated for $900–$1,500 with a professionally installed system
Housing and Foundation Types in South Paris
South Paris and Paris Hill offer a wide range of housing types: historic 19th-century homes on large lots with stone or mortared foundations, early 20th-century Craftsman and Colonial Revival homes near the village center, mid-century ranches along Route 26, and newer construction on the outer roads. Full basements are common throughout the village. Homes with block or poured concrete foundations can be effectively mitigated with sub-slab depressurization.
Radon in South Paris Well Water
Many South Paris homes are on private wells. Radon dissolved in well water is released into indoor air when water is used — in showers, dishwashers, washing machines, and faucets. This contributes directly to indoor air radon levels and is an exposure pathway that many homeowners overlook entirely.
We recommend that any South Paris home on a private well be tested for water radon alongside air radon. If water levels are elevated, we install aeration treatment systems that remove radon before it enters your home's plumbing. Learn more: Radon in Well Water — How It Works and How to Fix It
