Want to know the pH of your favorite bottled water brand?

In this guide, we’ve shared the pH levels of all the most popular bottled waters in the US.

📌 Key Takeaways:

  • pH is a measure of the hydrogen ions concentration in a liquid.
  • You can measure a solution’s pH level with a pH water meter, pH indicator paper, or colorimetric indicator.
  • Bottled water pH tends to range from around 5.0 to 9.0, but some bottled waters have higher or lower pH values than this.

🤔 What Is pH?

pH means “potential of hydrogen” and measures the concentration of hydrogen ions in a liquid.

The pH scale spans from 0 to 14. Acidic solutions have a pH value of below 7 – and the lower the number, the more acidic the solution. Any substance with a pH of 7 is considered neutral, and any solution with a pH value of above 7 is an alkaline solution. Again, the higher the number, the more alkaline the substance.

📏 How Do You Measure pH?

There are a few different ways to measure pH, including:

  • pH meter – A pH meter uses a pH-sensitive electrode that measures the voltage generated in a solution when it comes into contact with this electrode. Using a pH meter is one of the quickest and most accurate methods of determining your water pH, but only if it’s calibrated correctly.
  • pH indicator paper – pH indicator paper is specially-treated paper that changes color to give you an idea of a solution’s pH. You can compare the color of the paper to a color chart, which tells you its estimated pH value. This method is cheap and easy, but not as accurate as other methods.
  • Colorimetric indicators – A colorimetric indicator is a chemical compound that indicates the pH of a solution by changing color. The indicator should come with a color chart that you can refer to when determining the pH of the solution.

🔎 What Is The pH Of Bottled Water?

The pH of bottled water ranges from mildly acidic to mildly alkaline.

There’s no one pH that all bottled water brands aspire to, which is why there’s a disparity between all the bottled water brands we’ve listed in this guide.

How accurate is a bottled water’s pH reading? Manufacturers determine their water’s pH by taking a pH reading numerous times and pulling an average from the recorded data.

The pH level of the water you receive might be up to 1.0 higher or lower on the pH scale, since the pH of the water source may naturally fluctuate, or the pH may change slightly during storage and transportation (most manufacturers take their water pH readings prior to bottling).

So, keep in mind that the pH of your favorite bottled water might be a little higher or lower than documented by the manufacturer.

📖 What Factors Affect The pH Of Bottled Water?

There are a few different factors that affect the pH of bottled water. These include:

Water Source

The water source for a bottled water product has a big effect on its pH.

Different water sources, like wells, springs, or municipal water supplies, have varying pH levels. A water source is more likely to have a higher pH if it flows over or through soils or bedrock that contain carbonate, bicarbonate, or hydroxide compounds.

Water Treatment

The water treatment processes used by bottled water brands also affect the pH of the final product.

For instance, many bottled waters are treated with reverse osmosis filtration or water distillation. These processes remove more than 99.99% of total dissolved solids, including alkaline minerals, which often results in a drop in pH.

Mineral Additives

Some bottled water brands add minerals, like calcium and magnesium, to their water to give it a pleasant alkaline taste and improve its health properties.

These minerals contribute to water alkalinity and increase pH.

Healthy minerals found in water

Carbonation

Carbonation is when water is treated with carbon dioxide, which gives it a bubbly texture and a tart aftertaste.

The carbonation process reduces water’s pH and gives it a characteristic fizziness.

🧐 What Does pH Indicate?

If we just consider drinking water, pH gives you an idea of how the water will taste.

If the pH is low, water may have a slightly acidic taste with a sour afternote. Water with a very high pH may also taste bitter, and may even have a metallic taste, depending on its dissolved mineral content.

Brands of bottled water tend to aim for the ideal pH range for drinking water, which is typically between 6.5 and 8.5, since this gives water the most balanced taste.

For the sake of comparison, tap water in the US has a pH range of 6.5 and 9.5, depending on the water source and treatment.
