What about taste?  It seems everyone HAS to go to Timmys for their coffee (because Starbucks or home brewed sucks?).  I love the taste of a nice glass of water, but its different - VERY DIFFERENT - in every city.  Travel from Edmonton to Calgary and the water may be just as clear of bacteria - and have the same mineral content - but the taste puts me right off.  And I travel a lot.  In Las Vegas, I found the water undrinkable - tasted and smelled like sulfur.  Chicago?  UGH, the thought of the water there makes me gag still.  I read that the water in some European cities - has a high enough level of cocaine metabolites, that it is measurable in tap water.  What about some areas that have fracking - (you've seen the videos).  What about prescription medications?  Hormones?  Bottled water generally goes through reverse osmosis which can take out many of these things.  City water is "treated" - which means - coagulation, flocculation and disinfecting. You can drink it - I won't.
