The “,alkaline,” in ,alkaline, water refers to its pH level. A pH level is a number that measures how ,acidic or alkaline, water is on a scale of 0 to 14. For example, water with a pH of 1 would be very ,acidic, and water with a pH of 13 would be very ,alkaline,. So, a simple answer would be that ,alkaline, water is water with a higher than 7pH.
