I know I'm chiming in late here but, I would have a real issue drinking tap water in the middle of a major city. Sure it's filtered plenty, I have toured a few water plants because I sat on The Bow River Basin Water council. But the level of chlorine and perhaps more frightening aluminum, nesecessary to meet code is alarming. I am blessed because I live over one of the largest natural aquafers in the country which gives us very clean ground water that we further treat with U.V. technology so we don't need much chlorine at all. I can taste the difference when I go anywhere else though, it's generally pretty offensive.
