Drinking Water Fact Sheet: Radon

Radon is a naturally occurring radioactive gas formed by uranium and radium in rocks and soil. Most radon seeps into the air of buildings through sump holes, floor drains, cinderblocks, dirt floors, and cracks in foundations and concrete floors. However, radon can also enter homes via the drinking water supply. Groundwater dissolves radon from uranium-containing rock, resulting in generally higher concentrations of radon in well water compared with drinking water derived from surface waters, such as rivers and lakes.
