this topic is very interresting cause there is an international problem of water, not only in usa. even after killing bacteria water can be not healthy cause they are using much of chlorine and fluorine and that's dangerous for health, so natural mineral water is the best and it's drinkable without chemical treatement, but this one is not available for every one in the world, cause it's only 3pourcent of world water. thank you for this post.
