Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) If a water system has a single
				  fluoridation system which treats all the water distributed to consumers, the
				  supplier shall collect a daily sample for fluoride analysis, pursuant to
				  Section 64415(b), either
				  in the distribution system or at the entry point. If a water system does not
				  fluoridate all its water and/or has more than one fluoridation system, the
				  supplier shall collect one sample daily in the distribution system and rotate
				  the sample sites in order to be representative of the water throughout the
				  distribution system according to a monitoring plan the State Board has
				  determined to be representative. For water systems fluoridating as of January
				  1, 1997, the plan shall be submitted by July 1, 1998. For all others, the plan
				  shall be submitted prior to initiating fluoridation treatment. A water system
				  shall monitor only when it is operating its fluoridation system.
(b) If more than 20 percent of the daily
				  fluoride samples collected in a month by a water system pursuant to subsection
				  (a) fall outside the control range of optimal levels as determined by
				  temperature for that system pursuant to Section
				  64433.2, the system shall be out
				  of compliance with Section
				  64433.2.
(c) At least once a month, any water supplier
				  with an operating fluoridation system shall divide one sample and have one
				  portion analyzed for fluoride by water system personnel and the other portion
				  analyzed pursuant to Section
				  64415(a).
(d) Any water system with an operating
				  fluoridation system shall sample the raw source waters annually and analyze for
				  fluoride pursuant to Section
				  64415(a); samples
				  collected pursuant to Section
				  64432(c)(1) may
				  be used toward satisfying this requirement. All raw source water samples
				  collected under this subsection are subject to compliance with the fluoride MCL
				  in Table 64431-A.
(e) If any sample
				  result obtained pursuant to subsection (a) does not fall within the
				  temperature-appropriate fluoride level control range in Table 64433.2-A, the
				  water supplier shall take action as detailed in the water system's approved
				  fluoridation system operations contingency plan as specified in section
				  64433.8.
