Reverse aging, discusses pH in relation to ionized water in easy to understand language. He explains pH of ionized water this way. The mineral content in tap water affects the pH of the ionized water. City supplied tap water on average has a pH of 7.7 to 8.4. The pH value range for alkaline water after ionization is 9.5 to 10.4 whereas well water's pH range is 7.3 to 7.9 and after ionization, alkaline water from this source is generally 8.9 to 9.5. Alkaline water made by an ionizer is most similar to true mountain spring water.

He goes on to answer the question, "Could harm come by drinking too much alkaline water with a pH as high as 10?" His answer will surprise some and others not at all. Whang tells us, "No [there is no harm done]." He goes on to say that it takes 32 glasses of ionized alkaline water to simply neutralize the acidic effect of one glass of soda with a pH of 2.5 pH. This vital piece of information can shed more light on the Western lifestyle than any single bit of information. In America, because of diet and lifestyle habits, patterns and excesses, we systematically manufacturer acid in our internal terrain better than most other countries in the world.
