Radon in drinking water

Radon generally isn’t a problem with public drinking water systems because aeration in the treatment process releases dissolved radon to the atmosphere. However, if the water is from a private well, radon levels could be unacceptably high. We recommend testing well water if air radon concentrations in the occupied dwelling are above 4 pCi/L.

The U.S. Environmental Protection Agency (EPA) hasn’t established a Maximum Contaminant Level (MCL) for radon in drinking water.
