For basic information on bottled water,

Americans spend billions of dollars every year on bottled water. People choose bottled water for a variety of reasons including aesthetics (e.g., taste), health concerns, or as a substitute to other beverages.

If you have questions about bottled water, make sure you are informed about where your bottled water comes from and how it has been treated. The standards for bottled water are set by the United States Food and Drug Administration (FDA). The FDA bases its standards on the EPA standards for tap water.

• Read the label on your bottled water. While there is currently no standardized label for bottled water, this label may tell you about the way the bottled water is treated.
• Check the label for a toll-free number or Web page address of the company that bottled the water. This may be a source of further information.

The FDA regulations for governing the standards of “quality and identity” for bottled water are found in the Code of Federal Register 21 CFR 165.110. The FDA standards of quality state that domestic bottled water with no added fluoride may contain between 1.4 and 2.4 mg/L fluoride, depending on the annual average of maximum daily air temperatures at the location where the bottled water is sold at retail. Imported bottled water with no added fluoride may not contain fluoride in excess of 1.4 mg/L. Domestic bottled water with added fluoride can contain between 0.8 and 1.7 mg/L fluoride, depending on the annual average of maximum daily air temperatures at the location where the bottled water is sold at retail. Imported bottled water with added fluoride may not contain more than 0.8 mg/L fluoride. The labeling requirements by the FDA do not stipulate listing the actual fluoride content, so you will still need to contact the manufacturer to inquire about verified fluoride levels of their product.
