I read or heard someplace (too lazy to look it up, lol) that San Francisco is banning bottled water. Bottled water has a big footprint (PET bottles.) In the USA tap water has very strict standards, and one can get all kinds of filters to further post-treat it. At my company, instead of the big 5 gallon jugs, they have put in post-treatment systems that have a carbon filter and UV to destroy the chlorine taste. It works great!

What is your opinion about a BW ban? One drawback I can immediately see is at airports, where one cannot bring any liquid on a plane that has not been purchased/obtained locally. So variances would have to be put in place. But other than that...
