Many bedrock wells in southern Maine and New Hampshire test positive for radon. In Arundel, a short sample and a lab report show whether yours does, and a properly sized system takes care of the problem when it does.
Radon-in-Water Reduction for Arundel homes
Arundel is a mostly rural town inland of Kennebunkport, with wooded lots, small farms and quiet roads between Biddeford and Kennebunk. Bedrock under much of the town means newer wells are drilled into rock, with flow coming from cracks that vary from lot to lot.
Iron and manganese staining, hard water and sulfur smell are the usual complaints, with radon and arsenic as the health questions. Kennebunk, Kennebunkport, Biddeford, Lyman and Dayton surround the town, which keeps it close to several service routes.
What we see in York County wells
Inland York County is granite country, and drilled wells here regularly test high for radon. In Arundel, 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 Arundel
- Radon in water by a lab method that prevents gas loss
- 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
Radon levels can differ between nearby wells in Arundel. A sample from your own tap, taken before any treatment, is the only reliable starting point.
- 2
Decide the method
If you already have other treatment equipment, the radon system has to fit alongside it. We plan the line so each device sees the water it was designed for.
- 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 Arundel
Granular activated carbon beds capture radon as the water flows through. They need no power or venting, but they build up radioactivity over time and need careful placement and eventual disposal. Carbon is popular for moderate results.
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
- Carbon media that is past its replacement date
