Comprehensive Water Quality Monitoring Plan Fluoridation Plan
FLUORIDE OVERVIEW
Fluoride occurs naturally in the City of Huntington Beach drinking water wells at an average annual level of 0.4 mg/L. In addition to this natural level the City adds a small amount of fluoride to the water to promote dental benefits per a majority vote of the community during the early 1970s. The City's water has previously been fluoridated at the existing California Water Fluoridation Standards temperature-dependent optimal level of 0.8 mg/L and control range of 0.7 to 1.3 mg/L.
In the Spring of 2015, the Centers for Disease Control recommended water systems adjust their fluoride content optimal level to 0.7 mg/L, and the State Water Resources Control Board - Division of Drinking Water (DDW) advised public water systems in California to implement this change. In June, 2015 the City initiated a new water fluoridation standard optimal level of 0.7 mg/L, and control range of 0.6 to 1.2 mg/L.
FLUORIDE MONITORING
All "active" wells and import connections are monitored daily for fluoride concentration after fluoride treatment. In addition, one fluoride sample in the distribution system is monitored daily at one of fourteen locations on a rotating basis as identified on Distribution System Fluoride Sampling Locations list (Page 9-3), and shown on Water System and Sampling Stations map (Page 9-4). All of the daily source and distribution samples are collected and analyzed by trained City water system personnel, including weekends and holidays.
Once a month, all "active" wells are sampled and analyzed by City personnel prior to fluoride treatment to measure the natural fluoride concentration. Also, a monthly Split Sample is collected by the City personnel at one of the fourteen distribution system fluoride locations. Half of the sample is analyzed by trained City personnel and the other half analyzed by a State certified laboratory. This is done pursuant to the City's Fluoridation System Operations Contingency Plan (Page 9-5).
Once per year all wells and import connections are sampled by City personnel and analyzed by a State certified laboratory for the natural fluoride concentration.

Comprehensive Water Quality Monitoring Plan Fluoridation Plan Fluoridation System Operations Contingency Plan
City water system personnel will collect one sample on a daily basis, including weekends and holidays, at one of fourteen fixed locations that are representative of the water throughout the distribution system, and will rotate them on a continuous cycle. The fourteen locations are individual sample sites included in our Bacteriological Examination Route in the Comprehensive Water Quality Monitoring Plan, and are also identified in the Distribution System Fluoride Sampling Locations list in this Fluoridation Plan (Page 9-3).
Once per month water system personnel will collect one fluoride sample from one of the fourteen fixed locations and divide the sample. Half will be analyzed by the City and half will be analyzed by a laboratory certified by DDW pursuant to Section 64433.3 of the California Code of Regulations, Title 22, Chapter 15.
Each raw water source for Huntington Beach will be sampled and analyzed annually for the natural fluoride content by a DDW certified laboratory, and results sent to DDW via Electronic Data Transfer. The annual fluoride monitoring results must be in compliance with the fluoride Maximum Contaminant Level of 2.0 mg/L. Each active raw water source will also be sampled and analyzed for the natural fluoride content once per month by water system personnel and will be included in the Monthly Fluoridation Self-Monitoring Reports. If any source has been inactive for the month that is being reported then results of the most recent analysis will be included.
By the tenth day of each month following the month being reported, the City shall send operational reports to DDW which will include: 1) The fluoride compounds used and the calculated fluoride dose in mg/L; 2) Information on any interruptions in the fluoridation treatment which may have occurred during the month, including the duration of the interruption, an explanation of the causes and what corrective actions were taken to assure that fluoridation treatment was resumed in a timely manner; 3) The results of the daily monitoring for fluoride in the distribution system reported in terms of daily results, as well as ranges and number of samples collected; 4) The results of monthly split sample(s) analyzed by a DDW certified laboratory and City water system personnel.
The appropriate Fluoride levels for the City are summarized below:

Comprehensive Water Quality Monitoring Plan Fluoridation Plan
1. If at any time the fluoride level in the distribution system is found to be less than the control range,
0.1 mg/L above the control range up to a fluoride level of 2.0 mg/L, from 2.1 to a level of 4.0 mg/L, from 4.1 to a level of 10.0 mg/L or above a level of 10.0 mg/L, water system personnel will respond immediately. A site visit will be conducted to determine if there has been a malfunction or failure of the metering pumps. All necessary actions to correct any problems will be carried out without delay.
2. The procedure for shutting down the fluoridation equipment in the event of a fluoride overfeed, if the need to do so is identified by DDW and/or the water supplier, will be performed by City water system personnel as instructed by the Production Supervisor (see Operator's Emergency Plan for Overfeed of Fluoride).
3. The procedure for investigating the cause of an underfeed or overfeed will consist of checking the metering pumps to ascertain if they are working correctly. The supply lines and injection lines will be checked to make sure there is no obstruction, such as an air pocket, that may have caused an underfeed. An investigation would be conducted to determine if a power outage may have occurred that resulted in an underfeed or interruption.
A list of water system and DW personnel, with day and evening telephone numbers is included in the City of Huntington Beach Water Quality Emergency Notification Plan. Also listed in the Plan is the telephone number for Orange County Healthcare Agency personnel at (714) 433-6000.
5. The procedure for notifying the public, if instructed to do so by DDW, in the event of a fluoride underfeed extending for more than three months, or an overfeed exceeding 10.0 mg/L, is included on Page 2 of our Water Quality Emergency Notification Plan.
Operator's Emergency Plan for Overfeed of Fluoride
If any operator notices, or is notified of a fluoride overfeed which is defined as a fluoride level in excess of 2.0 mg/L, he is to respond to the site in question and STOP fluoridation until the problem is identified and corrected. The operator will notify the Water Production Supervisor whenever an overfeed situation occurs. Notification will be ASAP once fluoridation has been suspended. If the Supervisor is unavailable, notification will be to the Water Quality Supervisor, Water Quality Coordinator, Production Crewleader, etc. Notification will be via telephone, radio or Pagenet System.
