Why Mexico, Maine Has Elevated Radon Risk
Mexico's housing is primarily older mill-era residential — capes, colonials, and ranches built in the mid-20th century with block or poured concrete foundations. The town has a significant share of homes on private wells outside the municipal service area, adding water radon to the risk profile. Oxford County well water frequently tests above 4,000 pCi/L for dissolved radon.
- 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 Mexico
Mexico homes are predominantly mid-20th century construction — capes, ranches, and colonials with full block or poured-concrete basements. Older homes near the Route 2 corridor and central Mexico are common radon candidates. Properties outside the town's municipal water area are on private wells. Sub-slab depressurization is effective for the vast majority of Mexico foundation types.
Radon in Mexico Well Water
Many Mexico 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 Mexico 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
