The FDA protects consumers of bottled water through the Federal Food, Drug, and Cosmetic Act (FD&C Act). The “current good manufacturing practice” (“CGMP”) regulations require bottled water to be microbiologically safe. Bottlers of all types of waters typically use ozone gas as an antimicrobial agent. Bottled water is sealed with 0.1 ppm to 0.3 ppm dissolved ozone to guarantee microbial safety. Ozone gas is preferred over chlorine and other sanitizers because ozone disappears in less than 20 minutes after sealing, does not add residual taste, odors or disinfection byproducts to bottled water.
