What Is ORP in Drinking Water?

As shown in the demonstration above, ORP (Oxidation–Reduction Potential) measures a liquid’s tendency to gain or donate electrons—a common metric used in water quality testing and beverage analysis.

Many everyday drinks—including tap water, bottled water, soda, and sports drinks—often test with a positive ORP, reflecting a more oxidizing potential influenced by processing, storage, and additives.

Liquids that contain stronger reducing potential or antioxidant capacity may test with a lower or negative ORP. This is why more people are exploring hydrogen-rich water, ORP-balanced water systems, and advanced filtration technologies designed to improve water quality and hydration experience.
