What is alkaline water?

Alkaline water is water with a pH higher than 7. pH stands for Potential of Hydrogen, and the pH scale (which ranges from 0 to 14) measures how acidic or alkaline (basic) a solution is.

Zero is highly acidic, whereas 14 is highly alkaline (basic). In the middle of the pH scale is 7.0, neutral, and as a consequence, is neither acidic, nor alkaline (basic).

Natural water can have different pH levels depending on the soil, vegetation, weather, and sunlight in the area. For example, rainwater is slightly acidic because it absorbs carbon dioxide from the air. Spring water is usually alkaline because it flows over rocks and minerals which naturally raise the pH, making it alkaline.

This buffering ability arises from a mix of bicarbonate, carbonate, and hydroxide ions, with their relative proportions depending on the water's pH. Factors such as bedrock composition (commonly limestone), soil type, weathering processes, and precipitation patterns determine the dominant form of alkalinity. For instance, waters flowing through limestone-rich regions typically exhibit higher alkalinity compared to those passing through areas dominated by granite, conglomerate, or sandstone.

This is similar to Santevia water. Santevia adds minerals like calcium and magnesium, raising the pH up to 10.0. These minerals make the water healthier for you and make the water taste better.

Santevia water usually is around 8.5-9.5 pH, while tap water is usually neutral with a pH of 7.0.
