I can assure you you do. We all have radon gas, it comes from the ground. You can have varying amounts, but you will get some, it's naturally occurring. I've known two people with lung cancer that never smoked a cig in their life. I keep meaning to have my house checked. If you test high, it can be abated, never heard of it being in the water, but it stands to reason. I guess all well using folks should check that. Can it be abated from the water?Not something that i would want on my property.
