Turns out it's just tap water
Pepsico has been forced to change the labes on all Aquafina water bottles telling consumers that it's tap water. Watch for labels that state water is "PWS" or "public water source".
I think I spent $1.70 for a bottle of water at the gas station today. For tap water. Oops. Well, I never buy water, so I guess it is okay. Damned marketing machine. IMAGINE the profit. Pure profit.
