One of my earlier posts contained a YouTube video showing Indian farmers using soft drinks as pesticides because they were so contaminated with them. A recent study has found chemicals leaching into bottled water stored for 6 months. Specifically, antimony is being found. Think of all the potential uses for your bottled water.
On a related note, Mexico was considering a 5% tax on soft drinks. Apparently, Mexicans drink more soft drinks than any other nation on Earth. One of the reasons cited is that they are cheaper and more readily available than potable water. Hopefully they didn't plan to offer rebates for bottled water in conjunction with this tax.
