Bottled water may also contain flavors and/or added nutrients, or be used as an ingredient in beverages, such as diluted juices or flavored bottled waters. However, beverages labeled as containing sparkling water, seltzer water, soda water, tonic water, or club soda aren’t categorized as bottled water under the FDA’s regulations, but instead as soft drinks. The flavor/nutrient-added waters must also meet both bottled water standards and FDA safety requirements, and additives must be clearly identified on the ingredient label.
