Precise Radon Water Testing Services
for Asheville, Hendersonville & More
Stop radioactive gas from entering your home through the tap. Radon Control Products’ expert radon water testing protects families throughout Asheville, Hendersonville, Black Mountain, Brevard and other towns in the area by accurately identifying hazardous dissolved well contaminants.
How Does Radon Get Into Well Water?
Radon originates from the natural breakdown of uranium found in bedrock deep underground. As groundwater flows through these rocks, the resulting radioactive gas easily dissolves into the water supply.
When your private well pumps this groundwater up into your home, the dissolved radon comes with it. Later, when you use the tap for showering, doing laundry, or washing dishes, the agitation releases the trapped radioactive gas directly into your indoor air, increasing your overall exposure.

Benefits of Radon Water Testing
Professional radon water testing does more than detect hidden risks. It ensures a healthier water supply for your family while adding long-term value and peace of mind to your home.
Identify High Water Levels
Our professional testing determines exactly if your private well exceeds the proposed 4,000 pCi/L EPA action level.
Protect Long-Term Health
Discover hidden radioactive contaminants in your plumbing to drastically reduce your family’s daily risk of lung cancer.
Improve Indoor Air Quality
Running faucets releases trapped well gas indoors. Water testing identifies this hidden source of airborne contamination.
Highly Accurate Diagnostics
We utilize specialized water collection techniques and certified laboratory analysis to ensure the most precise results possible.
Routine Well Inspections
The EPA strongly recommends testing private wells periodically to monitor changing underground water tables and radioactive levels.
Post-Treatment Verification
If you install a specialized water filtration system, our follow-up testing confirms it operates at peak effectiveness.
What Are the Symptoms of Drinking Water With Radon?
Consuming water containing radon produces absolutely no immediate physical symptoms. You will never experience sudden stomach aches, nausea, or headaches. Instead, continuous long-term exposure silently increases your risk of developing severe internal health complications.
No Acute Illnesses
Drinking radioactive water does not cause sudden vomiting, fever, or digestive distress after taking a sip.
No Taste or Smell
You cannot detect radioactive contaminants through your senses, making professional diagnostic well testing absolutely essential.
Stomach Cancer Risk
Consuming high levels of dissolved radioactive gas over many years directly contributes to developing stomach cancer.
Airborne Lung Cancer Risk
Agitated tap water releases trapped gases into your indoor air, significantly increasing your risk of lung cancer.

What Our Clients Say
After I found out I have high radon levels in my well water, it was pretty difficult to find right mitigation specialist in my area as nobody is dealing with water mitigation here… Henri agreed right away to come out to do the installation even when it’s 2 hrs drive for him. He communicated very well each step of the whole process including well preparation and during installation explained very well how it works. I am happy I have it now and don’t have to worry about radon in water anymore. New AirWell model is very quiet and basically maintenance free. I would recommend Radon Control Products to everyone, very professional approach and excellent communication.

Henri and his very capable crew did a perfect job, showed care and concern with a reasonable price, I highly recommend them.
Ernie B.
★★★★★
Radon Control Products was the least expensive of the three quotes we got, and our test result after their work showed 0.9!
Chandler A.
★★★★★
Radon Control Products installed a radon water treatment unit at our new house. I found elevated radon gas levels in our well water, which is common in the Blue Ridge mountains where igneous and metamorphic rock can produce radon gas levels in groundwater well above acceptable safe levels. Henri quoted and installed the system as promised. I am pleased that radon levels in the water were not detected in the treated water. The system is very simple in function with no chemicals and reagents involved. And Henri is very easy to reach and very responsive.

Common Questions
About Radon Water Testing
Everything you need to know about radon water testing in Western North Carolina.
How long does it take to test for radon in water?
The turnaround time for radon water testing results depends on the method used and the laboratory processing the sample. In most cases, homeowners can expect results within five to ten business days after the water sample is collected and submitted to a certified lab. Some expedited options are available when timing is a priority, such as during a real estate transaction with a tight closing window.
Radon Control Products handles the collection process with the same precision applied to all of our radon testing work, ensuring the sample is properly gathered, labeled, and submitted without delays that could compromise accuracy. Once results are returned, we walk you through what the numbers mean and whether levels indicate a need for treatment. Understanding your results is just as important as getting them.
Is radon in water as dangerous as radon in the air?
Radon in water presents a real health concern, though it is generally considered a lower risk than airborne radon when evaluated in isolation. The primary danger with radon in water is not from drinking it directly, but from the gas that is released into the air when water is used for showering, washing dishes, or doing laundry. That released gas contributes to indoor radon levels, which increases the risk of lung cancer over time with prolonged exposure.
Ingested radon from drinking water has also been linked to a small increased risk of stomach cancer, though this is less significant than the inhalation risk. Radon water testing is the only way to determine whether your well water is contributing to elevated indoor radon levels. Addressing radon in water is an important part of a complete approach to protecting your household.
Does boiling water remove radon?
Boiling water will drive off some radon gas, but it is not a practical or reliable solution for managing radon in water on an ongoing basis. The process of bringing water to a boil does agitate and release dissolved gases, including radon, but it does so into your indoor air rather than removing the radon from your home entirely. In a kitchen or enclosed space, that could momentarily worsen air quality rather than improve it.
Boiling also does nothing to address the radon that is released during showering, which is typically the largest contributor to inhalation exposure from water sources. Radon water testing followed by proper treatment through a certified point-of-entry system is the only effective long-term solution. Radon Control Products can assess your well water and recommend the right mitigation approach based on your actual test results.
Can city or municipal water have radon?
City or municipal water supplies can contain radon, but the risk is generally lower than with private well water. Large public water systems draw from surface water sources like rivers and reservoirs, where radon dissipates naturally before reaching the treatment facility. However, municipal systems that rely on groundwater sources, such as deep aquifer wells, can still deliver water with detectable radon levels to homes.
Additionally, municipal water travels through an extensive distribution system before reaching your tap, and much of the dissolved radon escapes during that transit. Private well users bypass that process entirely, receiving water directly from a groundwater source where radon in water concentrations can be significantly higher. Radon water testing is still worth considering for municipal customers who rely on groundwater-sourced systems. When in doubt, testing is always the most reliable way to know what is in your water.
How often should I test my well for radon?
Radon water testing for private wells is recommended every two to three years under normal circumstances. Radon in water originates from the bedrock and aquifer geology surrounding your well, and while those conditions tend to be relatively stable, they are not static. Shifts in water table levels, changes in surrounding land use, or variations in seasonal groundwater patterns can all influence radon concentrations in your well over time.
If your initial radon water testing revealed elevated levels and a treatment system was installed, retesting should be performed after installation to confirm the system is working effectively, and then on a regular schedule going forward. Real estate transactions involving properties with private wells should always include radon water testing as part of the inspection process. Radon Control Products has extensive experience with well-based radon concerns and can guide you through the full testing and treatment process.
