Radon forms from uranium in rock and dissolves into groundwater, and a drilled well in Windham 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 Windham homes
Windham is a Rockingham County town in southern New Hampshire, mostly residential, with wooded neighborhoods, farmland and a growing commuter population. Homes in many neighborhoods rely on private wells, and newer subdivisions have wells of very different ages in a small area.
Hardness, iron and manganese are familiar complaints, and treatment equipment is common in the basements of local houses. Houses that sell quickly can change hands without a recent well test, so a new owner is wise to start with a full panel.
What we see in Rockingham County wells
Inland Rockingham County is granite country, and drilled wells here regularly test high for radon. In Windham, we treat a result above the state guideline seriously, and we like to confirm it with a second sample before committing to equipment.
What to test first in Windham
- A repeat water sample, to confirm a high first result
- Bacteria and nitrate, a baseline for any private well
- Iron and manganese, which can foul carbon beds

How it works
How we handle radon-in-water reduction, step by step
- 1
Test the water
A careful sample is everything for a gas. We fill the container with minimal agitation and ship it promptly, and the lab reports the level in picocuries per liter.
- 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
The system is installed on the main line after the pressure tank. Aeration units include a vent pipe to the outdoors and a re-pressurization pump; carbon beds include a bypass and shut-offs.
- 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 Windham
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 Rockingham County well.
When to think about radon in water
- A real estate test with a high radon result
- A household with a long, hot shower habit
- A planned renovation that will seal the house more tightly
- A change in the well, such as a new pump or deepening
