Bottled Water/Packaged Beverages Certification Process

How and why bottled water is regulated is not common knowledge and can be confusing. Like other bottled beverages, bottled water is regulated by the U.S. Food and Drug Administration (FDA) as a food product and must adhere to strict quality and labeling guidelines. Many states also have strict requirements for bottled water produced and/or sold within their borders.

What Does NSF Certification Cover?

NSF certification includes annual unannounced plant inspections of a bottler's operation, covering everything from the source of the water through disinfection and treatment all the way through the container closure process. Extensive product testing is performed for over 160 different contaminants for compliance with FDA regulations. FDA requires packaged water products to be tested regularly for the same contaminants as public tap water supplies. In addition to monitoring for microbiological contamination, packaged water products must also undergo testing for:

  • Inorganic contaminants (e.g. arsenic, nitrates and lead)
  • Volatile organic chemicals (e.g. pesticides and other synthetic chemicals)
  • Radioactive elements (e.g. radium)
     

Why Should I Care if My Bottled Water Is Certified?

In the U.S., the FDA requires bottled water companies to monitor and conduct regular testing of their products and sets maximum contaminant levels for regulated contaminants, but it doesn’t require bottlers to have independent audits or product quality testing by a third party. Because NSF is not a regulatory agency, NSF certification is strictly voluntary. Participation in the NSF certification program by packaged beverage companies demonstrates their commitment to producing quality products. Companies throughout the world also certify their bottled water to NSF standards so people everywhere can be assured of bottled water purity.
