What Is the Difference Between Distilled and Spring Water?

The difference between spring water and distilled water is that spring water is obtained from an underground spring source and distilled water is any water that has undergone the distillation process. Water sold as spring water must be pumped from underground springs, whereas distilled water may come from other sources.

Spring water must be treated during transport from the source to the bottling factory by processes similar to those used by municipal water facilities, such as chlorination and ozonation, to protect against contamination.

Distilled water is boiled, producing steam that is then condensed into a separate vessel. This process filters out any solid impurities, such as metals, particles and minerals. Further purification is required to remove organic impurities before bottling. Minerals may be added for taste.
