I praise the city of Seattle. They imposed a ban on bottled water. What a simple and yet fantastic idea. I don’t know how plays out legally, but for any place with a good water supply system, it should be a grand example. In my country, the controls for the quality of water are much strickter on tap water than on bottled water.
I often carry a bottle of (tap) water, but I should also stay away from the coolers-with-a-container. Noted. Will do.
