Radon in water matters mostly because it escapes into indoor air during showers, laundry and dishwashing. For Cumberland County homes with a high result, treating the water at the point of entry cuts that source at its start.
Radon-in-Water Reduction for Brunswick homes
Brunswick is a Midcoast college town on the Androscoggin River and Casco Bay, with village streets and a lot of rural land at its edges. Neighborhoods on public water sit next to others on private wells, so one street can have very different water situations.
Older houses near town may still run on shallow wells, while newer homes on the outskirts are typically on deeper drilled wells. Anyone buying in Brunswick on a private well should ask for a recent test and look at what treatment is already in the basement.
What we see in Cumberland County wells
Granite and metamorphic rock runs under much of the coast, and deep wells drilled into it can carry radon. Around Brunswick and the Casco Bay side of Midcoast, shallow sandy wells are less likely to, but a bedrock well in Brunswick should be tested rather than assumed.
What to test first in Brunswick
- Radon in water by a lab method that prevents gas loss
- Uranium and arsenic, the other common bedrock concerns
- Hardness and pH, which affect equipment choice

How it works
How we handle radon-in-water reduction, step by step
- 1
Test the water
We collect a radon-in-water sample with the lab's closed method so the gas is not lost. The result tells us how much radon the well delivers and how far it must be reduced.
- 2
Decide the method
The decision rests on your number, your house and your preferences. We explain the trade-offs between a vented tank and a carbon bed without pushing either.
- 3
Install and vent
Installation includes a leak check, a pressure check and a first test run. Controls are set and explained before we leave.
- 4
Verify the result
A treated-water sample proves the system reduces radon to a safe level. We retest after startup and at intervals, because performance is only known when it is measured.

What shapes the job in Brunswick
The retest after treatment is what proves the system. Radon is a gas, so sampling must be done carefully to avoid losing it before the lab sees it, and we follow the lab's collection method for your Cumberland County well.
When to think about radon in water
- A real estate test with a high radon result
- A home with a granite foundation or ledge nearby
- A planned renovation that will seal the house more tightly
- Treatment that has never been verified
Not sure whether radon is a question for your Brunswick well? A single carefully collected sample answers it. Call, and we will explain how.
