Do not buy bottled water

Bottled water is an unsustainable, wasteful and costly way of
distributing drinking water.  In addition it is, IMHO, a cynical
money making effort that has been surprizingly widely successful
at selling people something that should be nearly free. And in Mpls
on average the quality of tap water is better than bottled water.

There are numerous web sites that give details on this.
