I read about that guy!
I don't know what water Tim's sells (I don't buy bottled water due to the pollution factor of mfg. bottles and bottles in dumps etc. and the environmental cost of getting the water, bottling it, transporting it etc.) but it could be just plain old tap water that's been ionized or whatever they do to it. Lots of brands of bottled water do that.
Check it out, you might save yourself some money on water and gas..(per gallon, water is much more expensive to buy than gas!)
