Is Radon A Problem In Drinking Water Supplies?
Radon can enter a home through well water. It can be released into residences when the water is run. Generally, radon is not a concern with public drinking water systems, where the radon likely is released to outdoor air before reaching the home faucets. Compared to radon entering homes through soil, radon entering through water is generally a small source of risk.
