The problem in some parts of Europe and that's mainly in the touristic areas in summer is that the water has to be treated twice as quick as normal. hence, the bleach taste. Though it isn't bad for you, I'd go for the tasteless spring water on offer at the supermarkets.I don't know if USA have the same problems though if you're boiling it for hot drinks go ahead but just use bottled water for cold drinks. Apparently, a lot of Australiens boil their water before they use it for drinking.
