Just read an interesting article in Fast Company Magazine on bottled water. Here is an excerpt

In San Francisco, the municipal water comes from inside Yosemite National Park. It's so good the EPA doesn't require San Francisco to filter it. If you bought and drank a bottle of Evian, you could refill that bottle once a day for 10 years, 5 months, and 21 days with San Francisco tap water before that water would cost $1.35. Put another way, if the water we use at home cost what even cheap bottled water costs, our monthly water bills would run $9,000.

24% of the bottled water we buy is tap water repackaged by Coke and Pepsi.
