Ok well tap water in any American state has to meet EPA standards so even though the taste will cary widely, it's all safe to drink. Clearly some places have better tasting water than others - I live in Las Vegas and almost everyone uses a carbon filter for the tap water here because it's so mineral heavy.

However after living here 3 years I'm sort of used to it and drink it out of the tap with no problem - I think if I moved somewhere else and drank more pure water I probably wouldn't like it ;)
