Steven Forth has an excellent point. Banning water bottles will simply encourage the increased purchase of carbonated beverages and juices - from a public health perspective, this is not at all sustainable! Additionally, immunocompromised individuals (for example, those that are HIV+) require access to guaranteed clean water and, excellent as it is, our tap water presents a small but avoidable risk to these individuals. Focus should be geared toward increasing fountains as well as positive reinforcement for/encouragement of reusable bottles.
