I got turned off bottled water when I witnessed staff at an institution in which I worked walking around with bottles of it in their hands. No one was ever more than 50` from a tap, and it was in a town of about 10,000 with an excellent water source. All I could think was, `My. How precious we are.` Fashion statements on the go.

As per Penny`s remarks, some countries have water that would gag a maggot. One would be wise to follow her advice.
