Radon is something most homeowners in Connecticut already associate with air testing, especially in basements. What often gets missed is that it can also enter a home through well water. At Farmington Valley Plumbing, we’ve seen more homeowners start asking questions after noticing unusual readings or learning how water can carry gases indoors. That concern often leads them toward water treatment services in Avon, CT, when they want a clearer picture of what is moving through their plumbing system.
How Radon Moves From Water Into Air
Radon is a naturally occurring radioactive gas formed from uranium in soil and rock. The U.S. Environmental Protection Agency explains that radon can dissolve into groundwater and be released when water is used inside the home. When you shower, run a dishwasher, or use hot water at the sink, the gas can transfer from water into the air.
The impact is not always obvious because radon has no smell, taste, or color.
- Hot water use increases gas release into indoor air
- Showering creates fine water droplets that release radon quickly
- Dishwashers can introduce small bursts of radon into enclosed spaces
- Well water systems carry more risk than treated municipal supplies
Long-term exposure matters because the Centers for Disease Control and Prevention identifies radon as the second leading cause of lung cancer in the United States after smoking. The EPA estimates it contributes to about 21,000 lung cancer deaths each year.
What Happens Inside a Home With Radon in Water
Once radon enters indoor air, it can collect in enclosed areas like bathrooms, laundry rooms, and basements. Even though air testing is more common, water-based radon can be a contributing source that homeowners overlook. In some cases, addressing both air and water sources is part of a broader water filtration system strategy for the home.
We often see homeowners combine testing with system upgrades when concerns persist.
- Radon levels may rise during heavy water use
- Enclosed spaces trap released gas more easily
- Well water homes show higher variability in readings
- Water and air systems can interact in unexpected ways
Two Main Ways To Remove Radon From Water
There are two widely used methods for reducing radon in water. Each works differently, and the right choice depends on water conditions and household needs.
Aeration Systems
Aeration removes radon by mixing water with air, allowing the gas to escape before water enters the plumbing system.
- Radon is released into a vented air stream
- Treated water is delivered with reduced gas content
- Common in homes with higher radon concentrations
Granular Activated Carbon (GAC) Systems
GAC uses carbon media to trap radon as water passes through a tank.
- Radon adheres to carbon surfaces
- Works well for lower to moderate levels
- Requires periodic maintenance and monitoring
In some homes, we also evaluate whether a water softener installation or combined system approach makes sense when minerals and gas concerns overlap.
When Water Quality Is a Whole-Home Concern
Radon is only one part of the bigger picture. Well water can carry minerals, sediment, and gases that affect how plumbing performs over time. That is why many homeowners expand to a whole house water filtration system to address multiple issues at once rather than treating symptoms separately.
FAQs
How does radon get into well water?
Radon forms in underground rock and soil and dissolves into groundwater before entering private wells.
Can boiling water remove radon?
Boiling can release radon into the air, but it does not provide a complete or controlled removal method.
Is radon in water more dangerous than radon in air?
Radon in air is the primary health concern, but water can contribute to indoor air levels when used in the home.
Do all well water homes have radon?
Not all, but levels vary widely depending on local geology and groundwater conditions.
