Bottled water is not necessarily healthier than tap water and yet it costs much more! Although associated with healthy water, bottled water is not guaranteed to be any healthier than tap water. Often the only difference is the added minerals which have no proven health benefits.
A four-year study by the Natural Resources Defense Council shows that 1/3 of the bottled water tested contains levels of contamination which exceed allowable limits. Bottled water can also be slightly acidic, which may affect your body's pH balance. Finally, the environmental impact caused by the production and disposal of plastic bottles is harmful to our ecosystem.
