CA Health & Safety Code Section 116375

The department shall adopt regulations it determines to be necessary to carry out the purposes of this chapter. The regulations shall include, but not be limited to, the following:


The monitoring of contaminants, including the type of contaminant, frequency and method of sampling and testing, and the reporting of results.


The monitoring of unregulated contaminants for which drinking water standards have not been established by the department. The requirements shall be not less stringent than those adopted pursuant to paragraph (2) of subsection (a) of Section 1445 of the federal Safe Drinking Water Act, as amended (42 U.S.C. Sec. 300j-4 (a)(2)). Until the time that the department adopts regulations regarding the monitoring of unregulated contaminants, the department may, by order, require any public water system that has been shown to contain detectable levels of any unregulated contaminants to conduct periodic water analyses in accordance with conditions specified by the department. The water analyses shall be reported on a quarterly basis unless the department finds that more or less frequent analysis is necessary.


Requirements for the design, operation, and maintenance of public water systems, including, but not limited to, waterworks standards and the control of cross-connections, that the department determines are necessary to obtain, treat, and distribute a reliable and adequate supply of pure, wholesome, potable, and healthy water.


Requirements for treatment, including disinfection of water supplies.


Requirements for the filtration of surface water supplies at least as stringent as regulations promulgated pursuant to subparagraph (C) of paragraph (7) of subsection (b) of Section 1412 of the federal Safe Drinking Water Act, as amended (42 U.S.C. Sec. 300g-1 (b)(7)(C)).


Requirements for notifying the public of the quality of the water delivered to consumers.


Minimum acceptable financial assurances that a public water system shall be required to submit as a demonstration of its capability to provide for the ongoing operation, maintenance, and upgrading of the system, including compliance with monitoring and treatment requirements and contingencies. For privately owned systems not regulated by the Public Utilities Commission, the financial assurance may be in the form of a trust fund, surety bond, letter of credit, insurance, or other equivalent financial arrangement acceptable to the department.


Program requirements for the conduct of the public water system program by a local health officer under a primacy delegation from the department as set forth in this chapter. The requirements shall include, but not be limited to, the issuance of permits, surveillance and inspections, reporting of monitoring and compliance data, and the taking of enforcement actions.


Methods for determination of the number of persons served by a public water system for drinking water regulatory purposes.


The adoption by the State Department of Health Services, in consultation with the State Water Resources Control Board and representatives from operators of public water systems, of emergency regulations for the uniform, scientific sampling, and analytical testing protocols for oxygenates as defined in subdivision (k) of Section 51010.5 of the Government Code.
