Do I need to test for radon in my well water in Kennebec County?

If you're outside the city centers, you're very likely on a private well drawing from fractured granite. Dissolved radon in well water is released into indoor air every time you shower or use a faucet. We test and treat both air and water radon.

Why the Augusta, Maine Area Has High Radon

Kennebec County and central Maine consistently rank among the highest-radon regions in New England. Three geological and environmental factors explain why.

Granite Bedrock Along the Kennebec River

The Augusta region sits on uranium-rich granite bedrock that runs the length of the Kennebec River valley. Uranium decays into radium, which decays into radon gas. That gas migrates upward through fractured bedrock and enters homes through foundation cracks, slab joints, and utility penetrations. EPA has classified Kennebec County as Zone 1 — the highest risk designation — and roughly 38% of homes in the county test above the action level of 4.0 pCi/L.

Older Mill-Town Housing Stock

Augusta, Hallowell, Gardiner, and Waterville grew as mill cities along the Kennebec River. These communities have a high proportion of pre-1960 homes with stone-and-mortar foundations, block basements, and original construction that predates modern radon awareness. Older foundations allow more radon entry than poured-concrete slabs, and the dense urban neighborhoods mean many multi-family buildings share the same elevated risk as single-family homes.

Private Wells & Water Radon

Most homes outside the Augusta and Waterville city centers draw from private wells in fractured granite. Well water in Kennebec County routinely tests above 4,000 pCi/L for dissolved radon — and that radon is released into indoor air every time a shower runs, a dishwasher cycles, or a faucet opens. If your home has tested high for air radon, there is a meaningful chance your water radon is elevated too. We test and treat both sources — air and water — with a single service call.

Maine's Long Heating Season

Central Maine homes are closed up and heavily heated from October through April. This creates a persistent negative-pressure "stack effect" that pulls air — and radon — out of the ground beneath your foundation. Winter readings in Kennebec County typically run 30–50% higher than summer readings. If you tested in warm months and passed, a winter retest is worth doing before assuming you're safe year-round.

Is radon really that common in Kennebec County?

Yes. Kennebec County is EPA Radon Zone 1 — the highest risk designation — and roughly 38% of homes test above the EPA action level of 4.0 pCi/L. Many Augusta-area homes test between 6 and 15 pCi/L, one to four times the action level. The granite bedrock underlying the Kennebec River valley is some of the most uranium-rich in New England, and that geology doesn't change — every home in the area should be tested.

My home is a historic mill-era house — can you mitigate it?

Yes. We have extensive experience with the older housing stock common throughout Augusta, Hallowell, Gardiner, and Waterville. Stone foundations, block basements, mixed foundation types — our technicians assess each home individually and design a system that works with your structure. We also route exterior piping and fans in ways that minimize visual impact on historic properties.

Do I need to test for radon in my well water too?

If you're outside Augusta or Waterville city limits, you're very likely on a private well — and well water testing is strongly recommended. Most rural Kennebec County homes draw from fractured granite aquifers, and dissolved radon in well water is released into indoor air every time you shower, run the dishwasher, or use a faucet. We test and treat both air and water radon. Learn more about radon in well water.
