The pH level, or alkalinity of water, depends on the concentration of calcium, magnesium, potassium and sodium carbonates and bicarbonates in the water – the higher the content of these minerals, the higher the pH.
In nature, the pH level of fresh water is usually between 6.0 and 7.5. Of course, there is also water with a lower pH level, such as swamp water. In addition, there are several springs or groundwater with a pH of 9.0 or higher. Such waters can be considered alkaline. Unfortunately, there are few places in the world where such alkaline water production is possible in nature.
In addition, natural water may have too high a degree of mineralization, which means that it contains too high a concentration of dissolved minerals and trace elements that are harmful to the body.
