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 in the water, the higher the pH level.
In nature, the pH level of fresh water generally varies from 6.0 to 7.5. Of course, there are also waters with a lower pH level, for example, marsh waters. In addition, there are several sources or underground waters with a pH level of 9.0 or above. Such waters can be considered alkaline. Unfortunately, there are few sites in the world where the extraction of such alkaline water is possible in natural conditions.
Natural water can also have an overly high degree of mineralization, meaning that it has a too high concentration of dissolved minerals and trace elements, which is also bad for our bodies.
