Radon forms from uranium in rock and dissolves into groundwater, and a drilled well in Alton can carry it into the house. A radon-in-water system pulls it out of the supply before it can escape into the air you breathe.
Radon-in-Water Reduction for Alton homes
Alton lies at the southern tip of Lake Winnipesaukee in Belknap County, with shoreline communities, hillside roads and a quiet town center. Most homes outside the village use private wells, and many lake properties combine a drilled well with a septic system close by.
Cold winters and long driveways make freeze protection and pump sizing worth thinking about, especially in older camps. Iron, manganese and acidic water all show up in New Hampshire wells, so a full panel tells more than a basic bacteria check.
What we see in Belknap County wells
Lake-country wells are often drilled into granite, which is one of the common radon sources in northern New England. A Alton camp or lakeside home should check for radon in the water and in the air before the first cold winter.
What to test first in Alton
- A repeat water sample, to confirm a high first result
- Uranium and arsenic, the other common bedrock concerns
- A treated-water sample after the system starts

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
Aeration is the right answer for high results, carbon for moderate ones. We weigh space, power, venting, flow rate and long-term upkeep, then recommend one.
- 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
After the install we collect a fresh sample and send it to the lab. A good result closes the loop, and a poor one tells us what to adjust.

What shapes the job in Alton
An air test helps put the water result into context. Radon in indoor air comes mostly from soil gas, not water, so a home with a high water result may also need a separate air mitigation. We explain how the two work together near the southern end of Lake Winnipesaukee.
When to think about radon in water
- A drilled bedrock well that has never been tested for radon
- A household with a long, hot shower habit
- A water result above the state guideline
- A change in the well, such as a new pump or deepening
