How can I test my well for radon?
You can buy a radon test kit for water here:
Radon Test Kit
You may also contact NSF International at (800) 673-8010 and the Water Quality Association at (630) 505-0160.
You should not let radon enter your home through the pipes. Radon is the second most frequent cause of lung cancer, after cigarette smoking, in the United States.
