Good Drinking Water pH: Understanding the Ideal Range and Its Impact

 

When it comes to our health, water plays a crucial role. But have you ever wondered about the pH of your drinking water? Understanding the pH level is essential because it affects both taste and safety. In this article, we’ll explore what makes a good drinking water pH, why it matters, and how you can ensure your waterfalls are within the optimal range.

What is pH?

pH is a measurement of electrically charged particles in a substance, indicating whether it’s acidic or alkaline (essential). The pH scale ranges from 0 to 14:

  • Acidic water: pH below 7 (battery acid falls into this category).

  • Alkaline water: pH of 8 or above (strongly alkaline substances can have a pH of 14).

  • Neutral water: Pure water has a pH of 7.

Safe pH Levels for Drinking Water

The U.S. Environmental Protection Agency (EPA) recommends that municipal drinking water suppliers maintain a pH between 6.5 and 8.5. While pH isn’t strictly regulated, it’s considered an aesthetic quality of water. Here’s why it matters:

  1. Taste and Palatability:

    • Water with a pH within the recommended range tastes good and is pleasant to drink.

    • Low or high pH levels can affect the taste, with deficient concentrations giving the water a flat taste.

  2. Technical Effects:

    • High-dissolved solids (TDS) can produce hard water, leaving deposits on fixtures and corroding pipes.

    • Alkaline water can have an unpleasant smell or taste and may damage appliances.

  3. Safety and Contamination:

    • Acidic water (pH < 6.5) may indicate contamination with pollutants.

    • Alkaline water (pH > 8) isn’t necessarily unsafe but can have technical drawbacks.

Common Water pH Levels

  • Tap water: Varies but typically around 7.5.

  • Distilled reverse osmosis water: 5 to 7.

  • Common bottled waters: 6.5 to 7.5.

  • Bottled waters labeled as alkaline: 8 to 9.

  • Ocean water: About 8.

  • Acid rain: 5 to 5.5.

Alkaline Water Trend

Alkaline water, with a pH between 8 and 9, has gained popularity. Some claim it slows aging, maintains body pH, and prevents chronic diseases. However, scientific evidence supporting these claims is limited.

In summary, aim for water within the EPA-recommended pH range. Whether you prefer neutral or slightly alkaline water, staying hydrated with safe and palatable water is essential for overall well-being.
