There are several ways to get alkaline water, all with important considerations:
Natural Spring Water: At a pH between 8 and 9, natural spring water is one of the best alkaline water sources. When the water in natural springs travels over rocks, it picks up minerals that cause the water to become more alkaline. If you have access to a natural spring well, you may have alkaline water.
Bottled Alkaline Water: Both physical and online retailers offer dozens of brands of bottled alkaline water. The price of bottled alkaline water is usually higher than regular water, but not all brands are of the same quality.
Some companies add salts and chemicals to the water to raise the pH. The quality of plastic they use for the bottles may also be a concern because some types are known to contaminate water over time.
Be sure to research the brand of bottled alkaline drinking water carefully so that you are sure that it is high quality and safe. Or, you can install a home water system to get great-tasting alkaline drinking water on demand without driving to a store or waiting for delivery.
