:322 Radon in Water

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:322 EcoTip: Radon doesn’t always enter a home from the soil. Homes on wells or small community based water cooperatives should check their water for radon if elevated levels are identified in the home’s air. In some cases people have spent a few hundred to couple of thousand dollars to unsuccessfully fix their home’s radon problem – only to find out the source was their water – requiring a completely different fix. Municipal systems are required to monitor radiation levels – so they shouldn’t be an issue.

A variety of methods are available for removing radon from water. One method involves aerating the water and venting the radon gas to the outside before the water is brought into the home. Another method uses activated carbon to “scrub’ the radon from the water. Since the half life of radon is a little less than 4 days, two whole house carbon filters are used and alternated at 4 day intervals. This prevents the radon level from building up too high. 

If you suspect radon in water you can have it tested by contacting National Testing Laboratories.
