We have a filter that removes lots of things from the tap water including chlorine, fluoride, and nasty things like giardia. And yes, bottled water isn't regulated very well, if at all. We have stainless steel water bottles that we use if we need to take water with us (which is pretty much all the time if we're going to be gone for more than an hour.) Although our water quality is supposed to be good, Congress is trying to gut the clean water/air acts, so I don't have a lot of faith that our water quality will remain good.
