If you have a private well, it’s important to test your water for radon. Radon is an invisible, odorless gas that is found in the air and in water. It’s a naturally occurring element that can be harmful if it accumulates at high levels. Testing for radon in your water is the only way to know if it’s present and at what levels.
In this blog post, I’m going to explain how to test for radon in your water so you can stay safe and healthy. I am going to discuss these 5 areas of Radon to help give you a broad overview of this gas.

What is Radon?
Definition and Origins of Radon:
Radon is a naturally occurring, radioactive gas that is produced by the decay of uranium and thorium in the earth’s crust. These elements are present in rocks, soil, and groundwater, and as they break down, they release radon gas into the environment.
Radon gas can then enter homes and buildings through cracks in the foundation, flooring, or walls, as well as through well water. In addition to uranium and thorium, other elements in the uranium-radium decay series, such as radium and polonium, can also produce radon gas as they decay.
An important note: Radon gas is not produced by these elements directly, but is instead a byproduct of their radioactive decay.
Health Effects of Prolonged Exposure to High Levels of Radon:
Prolonged exposure to high levels of radon gas can be dangerous, as it has been linked to an increased risk of cancer. This is because radon decays into radioactive particles that can become trapped in the lungs and digestive and urinary systems and release energy that can damage cells and increase the risk of cancer over time.
Why Is It Important To Test Water For Radon In Potable Water?
Increased Risk of Exposure through Drinking Water. Drinking water contaminated with high levels of radon can increase the risk of radon exposure for individuals. Radon gas has a nasty propensity to seep into the air supply, or when water is utilized for food or culinary purposes, This could unknowlingly make you breathe in harmful particles and make you sick in the long run.
Importance of Testing:
Radon levels will fluctuate over time. So it is recommended to test for radon regularly to ensure that the levels remain within safe limits. This can help to detect any changes in radon levels and to take steps to reduce the risk of exposure if necessary.
Methods to test for Radon in water
There are several different methods for testing radon in potable water. The most common method is through the use of a radon test kit, which you can purchase at a hardware store or online. These kits typically come with instructions on how to collect a water sample and send it to a laboratory for testing.
It is important to follow the instructions carefully and to use a reputable laboratory for testing to ensure accurate results.
Another method for testing for radon in potable water is through the use of a radon detection device. These devices use sensors to measure the levels of radon in the water and can provide immediate results. These devices are generally more expensive than test kits, but they offer the convenience of being able to test for radon in real time.
There are professional testing services that can be hired to test for radon in potable water. These services generally use more advanced equipment and techniques to test for radon and can provide more detailed results. However, hiring a professional testing service can be more expensive than using a test kit or detection device.
I recommend the Radon Water Test from Tap Score. They have a lot of different types of tests for radiological in water. The tests range from $115 to upwards of $900 depending on the test. In fact, Tap Score is the best one-stop shop to solve all your water testing needs.
Side Note:
It is important to note that radon levels can vary depending on the location and the source of the water. For example, well water may have higher levels of radon than water from a municipal water supply.
It is also important to know that radon levels can fluctuate over time, so it is recommended to test for radon regularly to ensure that the levels remain within safe limits.
What to do about Radon in Water
If high levels of radon are detected in potable water, there are several steps that can be taken to reduce the risk of exposure. One option is using a water treatment system designed to remove radon from the water.
These systems work by passing the water through a filter or by using a chemical process to remove the radon.
Radon in water can easily be eliminated by simple aeration This process involves mixing the water with air and allowing the heavier, more volatile radon molecules to dissipate into the air. In some cases, more advanced processes such as reverse osmosis or activated carbon filtration may be used.
It is important to choose a water treatment system that is certified by a reputable organization, such as the National Sanitation Foundation (NSF), to ensure that it is effective at removing radon.
Factors that Affect Radon Levels in Water
Location and Source of Water: Radon levels can vary depending on the location and the source of the water. For example, well water may have higher levels of radon than water from a municipal water supply. This is why it is important to test for radon regularly, even if the water is from a known source.
Radon levels can fluctuate over time, so it is recommended to test for radon regularly to ensure that the levels remain within safe limits. This can help to detect any changes in radon levels and to take steps to reduce the risk of exposure if necessary.
What to Do When High Levels of Radon are Detected in Potable Water
If high levels of radon are detected in potable water, one option is to use a water treatment system that is designed to remove radon from the water. These systems work by passing the water through a filter or by using a chemical process to remove the radon.
It is important to choose a water treatment system that is certified by a reputable organization. One such as the NSF International (NSF), to ensure that it is effective at removing radon.
What about bottled water?
Another option is to use bottled water for drinking and cooking. This should be a temporary solution as it can be expensive and is not a good long-term solution. It is also important to note that bottled water is not necessarily free of radon and it is oftentimes contaminated with the gas.
Drilling a New Well or Installing a New Water Supply Line:
In some cases, drilling a new well or installing a new water supply line may be necessary to reduce the risk of exposure to high levels of radon in potable water. This option should only be considered if other methods are not feasible or if the radon levels are significantly above the recommended safe limits.
Final Thoughts…
The testing and removal of radon in potable water is an important process that needs to be undertaken to ensure safe levels. Radon comes from various sources, such as well water. Testing should be done regularly to detect any changes in levels.
Treatment systems are a great way to remove radon from the water and should be certified by a reputable organization. If the radon levels are too high, it may be necessary to drill a new well or install a new water supply line in order to reduce the risk of exposure. Finally, bottled water should only be used as a temporary solution if needed.
Look, it is important to test for radon in potable water to ensure that it is safe to drink. There are several different methods for testing radon, including test kits, detection devices, and professional testing services. Regular testing is recommended to ensure that the water remains safe to drink.
