Log In Bottled water might not be a bargain. One might save a lot of money just drinking filtered tap water. Well, for one thing, a lot of the pollutants in regular water are also in bottled water. In addition, as a side note that doesn't really pertain to saving money, bottled water is incredibly environmentally unfriendly. However, it is good to note that some areas have bad tap water. In those cases, I figure filtered bottled water would be a good option unless the water company can prove it's water has pollutants filtered out. What about chlorine in bottled water? Too much chlorine is a poison. That's another thing that needs to be looked out for.
