Is Your Bottled Water Acidic, Neutral, or Alkaline?

waters

It’s no small wonder that the world currently spends more than $100 billion per year on bottled water. But what is bottled water really? Many popular brands are simply tap water, ‘purified’ and bottled up to look more attractive and sold in mass quantity.

Many people would be surprised to learn that many of the most common brands of water measure very acidic on the pH scale. In fact, some well-known store brands could have a pH value as low as 4, while many others hover in the 5 to 6 range. A pH of 7 means neutral (ordinary tap water is commonly in the 7 to 8 range).

Highest-pH-bottled-waterAlkaline water, not included as part of this list, varies in pH from around 7.4 (mildly alkaline) all the way to 10 which is highly alkaline, sometimes referred to as ‘super pH’. Alkalife TEN Spring Water is at the top of the list with a pH of 10. (Click here to view an infographic showing the pH levels of many bottled waters).

We’ve put together a list showing the pH values of some of the more common brands of bottled water. The pH levels recorded are based on our tests, and waters were tested multiple times for accuracy. This number does not necessarily reflect the pH of the specific brands of water at all times, as other factors (such as the length of time bottled) may affect water pH. All of the following water bottles were tested the day after purchase and at the same temperature, and the test was performed using an electronic pH tester.

Store Brand Water: pH varies

Store brand water is usually just tap water. It is uncommon for very cheap bottled water to have any additional filtering. It is only recommended to buy these bottles of water for trips in which safe water is hard to come by, such as a backpacking trip into the mountains. The pH of the water varies with the public water source.

Propel ZeropH 3.5

Sold as a “fitness water”, Propel Zero is a flavored line of waters and actually contains many ingredients including sweeteners which make it very acidic. In fact, it scores as the most acidic among all the waters tested. In terms of pH, it is not much different from soda.

Aquafina: pH 5.5

Aquafina water comes from public water sources (tap water). It is thoroughly purified after it is obtained using a rigorous 7-step process. Aquafina measured a pH of approximately 5.5.

DasanipH 5.6

Dasani water also comes from public water sources rather than natural aquifers, but after filtration, Dasani is more taste-focused. The water has a few additives such as magnesium sulfate, potassium chloride, and trace amounts of sodium minerals. The pH of this water was approximately 5.6.

Arrowhead Spring WaterpH 6.8

Arrowhead is sourced from multiple springs around the United States, so the pH could vary. For this particular test it measured slightly below neutral pH at 6.8.

Crystal GeyserpH 6.9

Crystal Geyser is based in San Francisco, though like Arrowhead they use a number of spring sources around the United States. They claim to utilize a double disinfection process to purify the water. It registers at 6.9 on the pH scale, which is just below neutral.

Alkalife-578x90

Poland Spring: pH 7.2

Poland Spring water comes from a natural mountain spring. The water is thoroughly screened for contaminants, but many of the natural minerals can still be found in the water.

Nestle Pure Life: pH 7.3

Nestle Pure Life water is bottled from a municipal source and goes through a multi-step process of filtration that involves reverse osmosis and/or distillation. Afterwards, the water is infused with minerals.

Fiji: pH 7.3

Fiji water comes from an artesian aquifer where the water is naturally purified through volcanic rock. It is then filtered but not so much that it removes the natural mineral additives. This water’s pH was measured at 7.3.

Volvic: pH 7.5

Volvic water is drawn from the heart of the Parc Naturel des Volcans d’Auvergne in central France, a protected environment. Volvic is bottled exclusively at its source, the Clairvic Spring.

VOSS: pH 7.6

Voss water boasts an extremely low TDS (total dissolved solids). The water is bottled from a municipal water supply in Norway.

Smart Water: pH 7.6

Smart Water is somewhat misleading when it comes to the water source. Although some of the plants use protected groundwater sources, most of its facilities use public water sources. The water is purified through distillation, and it also contains electrolytes such as calcium chloride, magnesium chloride, and potassium bicarbonate. The pH of this water when tested was 7.6.

Deer Park: pH 7.8

Deer Park obtains its water from natural springs and filters its water thoroughly, attempting to make the water as pure as possible without additives. The pH of Deer Park water was approximately 7.8.

Penta: pH 7.8

Penta has no additives and claims to be antioxidant for the body. It is bottled from a municipal source and processed through a high pressured, spinning chamber.

Evian: pH 7.9

Evian water comes from a glacial spring where the water is naturally purified without the use of chemicals. It also contains minerals, including sodium, potassium, calcium, magnesium, bicarbonates, and more.

The pH tests performed were recorded manually and tested with the same machine, and they are not necessarily conclusive. However, they should be relatively close to accurate. It is important to know what type of water you are drinking and where it comes from. Even though many bottled waters taste similar, their mineral content, water sources, and pH levels may vary dramatically. Also, many bottled water companies distill or use reverse osmosis on their water, which strips it of nutrients. A few drops of Alkalife pH booster drops to any of these waters will raise the pH as well as mineral content considerably, so no matter what type of water you have available for drinking, you can be sure it is alkaline.
