Coke is having a real problem labeling the source of Dasani bottled water.

Bottled water corporations spend tens of millions on advertising every year, promoting bottled water as better than tap water and undermining confidence in our public water systems.

Both Pepsi and Nestlé have already taken steps to spell out "Public Water Source" on both Aquafina and Pure Life brands, letting consumers know where their water is coming from. When will Coke reveal the sources and sites of the water it uses for bottling its Dasani brand?
