Radon In Water
Return to Radon Page
Compared to radon entering the home through soil, radon entering the home through water will in most cases be a small source of risk. Radon gas can enter the home through well water. It can be released into the air you breathe when water is used for showering and other household uses. Research suggests that swallowing water with high radon levels may pose risks too, although risks from swallowing water containing radon are believed to be much lower than those from breathing air containing radon.
While radon in water is not a problem in homes served by most public water supplies, it has been found in well water.  If you’re on a public water supply and are concerned that radon may be entering your home through the water, call your public water supplier. If your water comes from a private well, contact a lab certified to measure radiation in water to have your water tested.

EPA Drinking Water Hotline (800-426-4791)
Radon problems in water can be readily fixed. The most effective treatment is to remove radon from the water before it enters the home. This is called point-of-entry treatment. Treatment at your water tap is called point-of-use treatment. Unfortunately, point-of-use treatment will not reduce most of the inhalation risk from radon.

Call your state radon office or the EPA Drinking Water Hotline (800-426-4791) for more information on radon in water.
