The second place on our list of healthiest bottled water brands in 2018 goes to another brand from the U.S. that is definitely one of the safest bottled water brands. This spring water is naturally alkaline, which means that during filtration through the layers of rocks, essential minerals are being absorbed. The best thing is these layers also protect water from pollution. As you guess, there is no need to add anything to this water. It is just pure, fresh and above all, it is healthy.
