The pH scale measures the acidity or alkalinity of a substance. The middle of the scale is a 7. This is neutral—neither acid nor alkaline. Pure water is here. Substances that are acidic—like lemons, colas, and stomach acid—have lower pH levels. Alkaline substances—like baking soda, bleach, and ammonia—have higher numbers

The pH scale is logarithmic. This means that every step along the scale is 10 times greater than the last step.

A pH of 5 is 10 times more acidic than a pH of 6. A pH of 4 is 10 times more acidic than a pH of 5 and 100 times more acidic than a pH of 6. A Coca-Cola Classic (with a pH of 2.5) is over 10,000 times more acidic than a glass of whole milk (with a pH of 6.9). As you can see, things escalate rather quickly.

Tooth enamel starts to dissolve around 5.5 on the pH scale. Dentin, a substance beneath the enamel, starts to dissolve around 6.5. Dentin can be exposed at the gum line or through tooth wear. So if your teeth are perfectly healthy, you can tolerate a more acidic environment. But if you’re like most of us, you won’t want your teeth to spend significant time below a 6.5 on the pH scale.

 WATER SOURCES PHS

Now let’s see how various WATER sources fall on the scale:

Alkaline: Essential: 9.0, Real Water 8.0, Evamor:8.0, Music Mountain: 7.88, Super Chill: 7.50, Absopure: 7.5, Zephyrchills:7.5, Fiji: 7.50

Safe: Volvic: 7.0, Eternal: 7.0, Evian: 7.0, Arrowhead: 6.83

Borderline Safe: Gerber Pure Water: 6.5, Smart Water: 6.5, Great Value Walmart: 6.5

Harmful to Dentin: Spring by Dannan: 6.40, Deer Park: 6.3, Dasani: 6.08, Voss: 6.0, Crystal Geyser: 6.0, Ice Mountain: 6.0, Sam’s Choice: 5.90, Poland Spring: 5.8, AquaFina: 5.67, Great Value: 5.53

Harmful to Enamel: Perrier: 5.50, Deja Blue: 5.49, Ozarka: 5.49, Function: 5.0,Dasani: 4.5,Penta: 4.0,Propel Fitness Water: 3.6, Propel Zero—Gatorade: 3.5, Dasani Lemon: 3.48, Vitaminwater: 3.4, Fruit ² O: 3.10

As it turns out, quite a few popular bottled waters are dangerously low on the pH scale. They’re so acidic that prolonged exposure could wear away tooth enamel and cause cavities.
