Radon Myth #7
Myth #7 – All homeowners should conduct water radon tests. This statement is alarmist. It would be more accurate to say, “In some instances, a water radon test may be advisable.”
Fact: The EPA has proposed the action level in water to be 300 pCi/L compared to 4 pCi/L in an air sample. If you are on a public water system your water should already be tested for radon as well as other contaminants. If you have well water the first and most important step is to test your air for radon. Then consider a water test if your levels are high.
Radon mitigation systems for water are expensive to install and expensive to maintain.
