Does Kirkland Water Have Fluoride?

Kirkland water contains little to no fluoride in it. The company produces at least four types of bottled water, and they all differ in their fluoride content.

The Italian sparkling water contains 0.1 ppm, the spring water has 0.3, and the purified and ionized water both contain 0.0 ppm of fluoride.

At around 0.3 ppm, the spring water has the highest fluoride concentration. However, considering that the FDA says bottled water with up to 0.7 ppm of fluoride isn’t dangerous, Kirkland spring water is safe, as its fluoride content is well below the allowed limit.

Additionally, many other water brands have fluoride concentrations much closer to the limit imposed by the FDA, so Kirkland remains one of the better choices if you’re trying to avoid this particular chemical.

Where Does Kirkland Water Come From?

As the name might suggest, Kirkland water comes from the city of Kirkland in Colorado. More specifically, the water is sourced from the Cedar River Watershed and the South Fork Tolt River Watershed. Both locations are near the Rocky Mountains, and the area is remote, so the water source is clean and unpolluted.

Once sourced, the raw water is then shipped to the Niagara Bottling Company in California and put through a UV and carbon filtration process twice to eliminate any possible impurities or contaminants. The carbon block removes dirt particles, odors, and unpleasant tastes, while the UV light destroys any bacteria in the water.

This process also removes metals like lead and copper from the water and minerals like calcium and magnesium that make the water hard. The filtration process leaves around 0.5 ppm of chlorine in the water and 5 ppm of iron, both of which are acceptable and even preferred amounts (in the case of iron).

Finally, the water is mineralized, put into BPA-free bottles, and shipped throughout the US.

If you’re unfamiliar with the term BPA, it’s an abbreviation of Bisphenol A – an industrial chemical created during plastic production that can contaminate the food or beverage inside a plastic container made with it.

Kirkland Water’s pH level

Kirkland’s signature alkaline water is rated to have a pH value of 9.5, while the other types of Kirkland bottled water have a pH value of 6. For reference, the ideal pH value of drinking water should be between 6.5 and 8.5.

The pH scale goes from 0 to 14, 0 being incredibly acidic and 14 being extremely alkaline. A pH value of 7 is considered to be neutral since it’s right in the middle of the range, so it’s neither too alkaline nor too acidic.

pH Scale

Drinking alkaline water doesn’t carry any significant benefits. Alkaline water is considered to have fewer contaminants, and it can neutralize the effects of overly acidic water on your body, but that’s about it.

On the other hand, drinking water that’s too acidic can be a health concern, but this mainly applies to natural, unfiltered water. Natural water with a pH value of 6 or lower typically also contains bacteria or other contaminants that can cause you to get sick.

However, Kirkland water undergoes extensive filtration, so any potential contaminants are removed before the water is bottled. Therefore, the fact that the water is half a decimal point below the ideal pH value doesn’t mean it’s bad for your health.

Additionally, according to McLean Dentistry, most bottled water have a pH value of around 6 or maybe even lower:

  • Aquafina has a pH value of 4.0
  • Dannon Spring Water has a pH value of 5.5
  • Smart water has a pH value of 4.0
  • Vitamin water has a pH value of 4.0, and so on

Kirkland’s bottled water has a standard pH value, and Kirkland’s alkaline water has a higher-than-average pH value. Both are extensively filtered to ensure they are safe to drink.


Not only does Kirkland water not have any fluoride at levels that would be considered unsafe for consumption, but it also doesn’t contain any common water contaminants. Additionally, all bottles are made from BPA-free materials.

All-in-all, two types of Kirkland water contain traces of fluoride, the Italian sparkling water and the spring water, while the other two, the purified water and the ionized water, do not. This, along with its good pH level and the rigorous filtration it undergoes, makes Kirkland water very clean and safe to drink.

My name is Scott Winfield and researching and writing about water filters and other strategies to purify water has become my full time passion in recent years.

  1. I just bought a bottle of Keto Chow Electrolytes and was wondering if Kirkland water contains enough electrolytes so that it makes buying them unnecessary.

    1. Hi Ruth, first, there are a variety of different Kirkland water products available. If you’re referring to jus the normal spring water they offer, then you should know that they don’t compare appreciable amounts of the minerals that you seem to be after with the Keto Chow product. if you have a distinct need for the type of profile that the Keto Chow provides, you are best served with using their product or looking for other products that are specifically tailored towards providing a robust and specifically tailored electrolyte combination that normal spring water products will not provide.
