Section 111175 Of Article 12. Bottled, Vended, Hauled, And Processed Water From California Health And Safety Code >> Division 104. >> Part 5. >> Chapter 5. >> Article 12.

. (a) In addition to the requirements of Section 111170, if a bottler, distributor, water hauler, retail water facility operator, or vending machine operator provides information in the labeling or advertising stating or implying that this water is of a specific water type (for example, "spring water") or treated in a specific manner (for example, "purified"), the type or treatment shall be clearly labeled in an easily readable format. In order to be so labeled, the source or treatment shall conform to the definitions established in Section 165.110 of Title 21 of the Code of Federal Regulations, or, if not defined in that section, with the following criteria:
  (1) "Mineralized water" means bottled or vended water that meets the requirements of "mineral water" except that the water contains added minerals.
  (2) "Natural water" means bottled or vended spring, artesian well, or well water that is unmodified by mineral addition or deletion, except "natural water" may be filtered and shall be sanitized with ozone or an equivalent disinfection process and treated to reduce the concentration of any substance that exceeds safety standards established by the department.
  (3) "Naturally sparkling water" means bottled water or vended water with a carbon dioxide content from the same source as the water. "Sparkling," "carbonated," or "carbonation added" means bottled water or vended water that contains carbon dioxide.
  (4) Notwithstanding any other provision of this section, water from a public water system that is unprocessed by the bottler or vendor shall be in compliance with Section 165.110(a)(3)(ii) of Title 21 of the Code of Federal Regulations.
