PepsiCo's Aquafina bottled water, which currently carries the cryptic label "Bottled at the source PWS" will soon spell out the acronym: "public water source." It's tap water, in other words, as is CocaCola's Dasani and almost 40% of bottled water sold.
So why, asks The Economist, is bottled water so popular? Because, answers The Economist, bottled water is less likely to be contaminated or poisoned by terrorists.
Never mind the fact that they only cite cases in which bottled water was contaminated to make this point. If there were serious safety issues with public water, that would be a reason to improve regulations for public water, not expect everyone to buy bottled. Blimey.
