Frequent Questions

My drinking water comes from a reservoir. Do I need to be concerned about radon in my drinking water?

Radon is only a concern if your drinking water comes from underground sources. If radon is contained in water that comes from a surface water source, such as a lake or river, it is generally released into the air before reaching your water supplier or home (Radon in Drinking Water: Questions and Answers, EPA815-F-99-007, October 1999).
