The Truth about pH Levels in Drinking Water: Everything You Need to Know

Water, the elixir of life, sustains us in more ways than we can imagine. Yet, in our quest for hydration, we often overlook a crucial aspect – pH levels. Understanding the pH of your drinking water is not just about scientific curiosity; it’s about ensuring your well-being. Our experts explain what is pH, what’s a safe pH level and how to measure it. 

What is pH level? pH is short for “potential of hydrogen,” which denotes the acidity or alkalinity of a substance. It’s measured on a scale from 0 to 14, with neutrality at seven. pH values below seven denote acidity, while those exceeding seven indicate alkalinity. As pH diminishes, acidity escalates, whereas higher pH levels signify heightened alkalinity.

The determination of acidity and alkalinity hinges on hydrogen ions (H+) and hydroxide ions (OH-) in the water. These ions are crucial for many chemical reactions and biological processes, underscoring the importance of pH as a fundamental measure of water quality.

Best pH Levels for Drinking Water

The optimal pH range for drinking water falls between 7 and 8.5. This range ensures that water is neither acidic nor alkaline, maintaining a balance compatible with our body’s natural pH levels. Water with a pH below 6.5 or above 9.5 may raise concerns and should be carefully assessed. 

Water falling within the safe pH range satisfies thirst and plays a crucial role in supporting bodily functions. It facilitates digestion, hydration, and the absorption of nutrients while concurrently reducing the likelihood of experiencing adverse health effects linked to extreme pH levels.

What If I Drink Water with Unsafe pH Levels?

Drinking water with pH levels outside the safe range can have various implications on health.  It can cause gastrointestinal discomfort and long-term health issues such as dental erosion and bone health deterioration. Acidic water may also corrode pipes, leaching metals like lead into the water supply.

Conversely, excessively alkaline water may alter the body’s natural pH levels, potentially disrupting metabolic processes. Chronic water consumption with extreme pH levels could lead to alkalosis, characterized by nausea, muscle twitching, and confusion.

While occasional exposure to water with slightly elevated or reduced pH levels may not cause immediate harm, consistent consumption of such water over time can negatively impact health. Therefore, it’s crucial to monitor and maintain the pH of your drinking water within the safe range.

What is Alkaline Water?

Alkaline water’s popularity is primarily attributed to its perceived health benefits from its elevated pH levels. Supporters assert that alkaline water neutralizes body acidity, aids in detoxification, and improves hydration. However, ongoing research prompts a cautious approach to these claims, emphasizing the need for skepticism and critical evaluation.

Alkaline water typically has a pH greater than 8.5, often achieved by adding calcium, magnesium, and potassium minerals. Proponents argue that these minerals impart alkalinity to water, making it more beneficial for health.

However, skeptics argue that the body’s pH regulation mechanisms render the consumption of alkaline water unnecessary. The human body maintains a tightly regulated pH balance, primarily through the lungs and kidneys, eliminating excess acids or bases. As a result, the impact of alkaline water on one’s overall health remains a point of contention among scientists and healthcare professionals.

What is the pH of Popular Bottled Water Brands?

The pH levels of bottled water can vary depending on factors such as the source of water and any treatment processes it undergoes. Here are the approximate pH levels of some popular bottled water brands:

  1. Evian: Evian water typically has a pH of around 7.2 to 7.4, making it slightly alkaline.
  2. Fiji Water: Fiji Water tends to have a pH level of about 7.7, which makes it slightly alkaline.
  3. Dasani: Dasani water has a pH level between 5.0 and 7.0, making it slightly acidic and varying depending on location and processing methods.
  4. Smartwater: Smart water’s pH is usually around 6.0 to 7.0, making it slightly acidic to neutral.
  5. Aquafina: Aquafina water typically has a pH level between 5.5 and 7.0 or is slightly acidic, depending on various factors such as location and treatment processes.


It’s important to note that these pH levels are approximate and can vary slightly depending on factors like the bottling process and storage conditions. Additionally, some bottled water brands may provide information about pH levels on their packaging or websites for consumers to reference.

How Do I Measure the pH Levels in My Home’s Water?

Testing the pH of your home’s water is straightforward. You can use pH testing kits available at hardware stores or online retailers. These kits typically include pH strips or electronic pH meters.

To measure the pH of your drinking water accurately, follow these steps:

  1. Gather a water sample in a clean container. Ensure the container is free from contaminants that could affect the test results.
  2. Dip the pH strip into the water sample or use the electronic pH meter according to the manufacturer’s instructions.
  3. Wait for the specified duration, typically a few seconds, for the pH strip to change color or for the electronic pH meter to display the pH reading.
  4. Compare the hue of the pH strip to the accompanying color chart or take note of the pH reading displayed on the electronic pH meter.
  5. Record the pH value obtained as it represents the acidity or alkalinity of your drinking water.


Regular testing, especially if you have concerns about your water quality, can provide valuable insights into its composition. Monitoring the pH of your drinking water allows you to promptly detect any deviations from the safe range and take necessary actions to address them.

How to Fix Unsafe pH Levels?

If your water’s pH falls outside the safe range, there are several measures you can take to address it:

  1. Filtration: Set up a water filtration system that can regulate pH levels, like reverse osmosis or alkaline water filters. These systems eliminate impurities and stabilize pH, guaranteeing the safety and healthfulness of your drinking water.
  2. Additives: Certain additives or mineral cartridges can help raise or lower pH levels, depending on your water’s initial acidity or alkalinity. For example, adding calcium carbonate can increase pH levels, while citric acid can decrease them. However, using additives cautiously and following recommended dosages is essential to avoid overcorrection.
  3. Consultation: Seek professional guidance from water quality experts to assess and rectify any underlying issues contributing to unsafe pH levels. They can conduct comprehensive water tests, identify potential sources of contamination, and recommend appropriate solutions tailored to your specific needs.

 

Innovations in water filtration technology have paved the way for advanced systems like the Kind Water 6-Stage Reverse Osmosis Drinking Water System. This cutting-edge system goes beyond conventional filtration methods, employing a sophisticated 6-stage process to purify water to its pristine form. What sets it apart is its incorporation of a remineralization cartridge, which restores essential minerals, balancing the pH of the water to optimal levels. The Kind Water system lets you enjoy safe, clean, and pH-balanced drinking water. It’s a testament to the commitment to enhancing water quality and promoting well-being for you and your family.

The pH of drinking water plays a pivotal role in maintaining our health and well-being. Understanding safe pH levels, regularly testing your water, and taking necessary corrective actions are essential to ensure access to clean and healthy drinking water. By staying informed and proactive, you can safeguard yourself and your loved ones against the potential risks associated with imbalanced pH levels in water. Remember that water is not just a thirst-quencher; it’s a vital component of life, deserving of our attention and care. Let’s prioritize water quality and embrace the journey towards optimal hydration and well-being.
