There’s no doubt you should test your home for radon, but should you go so far as to test your home’s water supply for traces of radon? As far as myths about radon go, this is a bit of a mixed bag.

Test the Air, Then Test the Water 

The right way to go about detecting potential radon is to test the air before you test the water. Think about it: You likely get all of your water from a public infrastructure. That means it’s the city’s responsibility to test the water for radon and share their results. Do yourself a favor and take a look at those public results, just to be on the safe side

On the other hand, maybe you use water from a well. If so, you’ll most certainly want to personally test it for radon.
