We normally use the bottled water, mainly because it tastes better. A couple times the tap water had kind of a sulfer-like taste.. Anyways, I see that some use the tap water to brush their teeth. Hate to say, but if there is anything really bad in that water, it does not take a gallon to make you sick. One drop would be quite enough. So if you are not getting sick after brushing, it's probably not all that bad.
