Radon in Water

Radon in Water

Well, well, well, if it isn’t radon in water!

Most people who have heard of indoor radon probably know that it comes from the ground. Radon is a radioactive decay product of uranium, which exists in the soil in countless counties across the U.S. Radon gas enters through the tiniest cracks in a house’s foundation, and can accumulate to high levels in the home, especially in the lowest levels. However, there is another common way for radon to enter the home: through the water supply.

Why is radon in water a problem?

Radon can get into the water supply by seeping into the water from the ground. This generally occurs in underground water supplies, such as wells. The radon can then leave the water and enter the air inside the home through water vapor. This is most frequently seen in rooms such as the bathroom and kitchen, where there tends to be water running frequently. If the radon levels in the water are high enough, it can cause higher levels to accumulate in the home and can pose a danger to the occupants. While the radon that escapes into the air is the primary danger, the radon remaining in the water can cause problems as well. Evidence has shown that radon in drinking water can pose a risk for developing stomach cancer.

How do you identify an issue?

Since radon in water issues are most commonly seen in homes that use well water, that is the main risk factor. Radon in Water tests can be performed to know how much radon is in the water supply.  High radon levels in rooms with heavy water use give an indication that there might be high levels of radon in the water. Test kits for both air and water can be found at https://www.radon.com/.

What is the best solution to radon in water?

Just as there are ways to mitigate radon coming through the ground and into your home, there are ways to remove radon in water. The best method of removal is aeration, which bubbles the water, releasing the radon gas into water vapor, and then safely vents the gas into the outside air above the roof. This process also removes other contaminants, such as volatile organic compounds (VOCs).
