Well; in Australia where I come from, they encourage us to drink tap water because they put flouride (flourine) in it to help strengthen our teeth.

But personally; I drink Spring Water simply because it's bottled.

But! If I didn't get a stomach ache every time from drinking tap water; I'd go with the tap water.

Also, I believe it also depends on where you come from; some places may treat the water to be better for you and some places probably not.

But usually; there IS a difference between tap water and bottled water.
