Health & Saf. Code, § 111080

The quality and labeling standards requirements for bottled water and vended water, including mineral water, shall include all standards prescribed by Section 165.110 of Title 21 of the Code of Federal Regulations. In addition, bottled water and vended water, when bottled, shall comply with the following quality standards and any additional quality standards adopted by regulation that the department determines are reasonably necessary to protect the public health:

(a) Bottled water and vended water shall meet all maximum contaminant levels set for public drinking water that the department determines are necessary or appropriate so that bottled water may present no adverse effect on public health. New or revised allowable levels or monitoring provisions adopted for bottled water by the United States Food and Drug Administration under the federal Food, Drug and Cosmetic Act that are more stringent than the state requirements for bottled water are incorporated into this chapter and are effective on the date established by the federal provisions unless otherwise established by regulations of the department.

(b) Bottled and vended water shall not exceed 10 parts per billion of total trihalomethanes or five parts per billion of lead unless the department establishes a lower level by regulation.

(c) Bottled and vended water shall contain no chemicals in concentrations that the United States Food and Drug Administration or the state department has determined may have an adverse effect on public health.
