1(1) Fluoride levels in drinking water shall not exceed the primary maximum contaminant level under Rule 1762-550.310, 18F.A.C., or the secondary maximum contaminant level under Rule 2762-550.320, 28F.A.C. The recommended optimal fluoride concentration for fluoridated community water systems is 0.8 milligram per liter. The recommended fluoride control range for fluoridated community water systems is 0.7 to 1.3 milligrams per liter.
61(2) Equipment and Installation.
65(a) Fluoride chemicals shall be fed into drinking water proportional to flow. Where the flow rate is reasonably constant, this may be accomplished by electrically interconnecting fluoride metering pumps with well or service pumps or by otherwise designing fluoride metering pumps to operate only when well or service pumps operate. Automatic flow proportioning control of fluoride metering pumps shall be provided where the flow rate varies significantly (i.e., where the flow rate varies by more than 20 percent).
143(b) Fluoride metering pumps shall have antisiphon protection.
151(c) Tanks and containers holding fluorosilicic acid shall be vented only to the outside atmosphere.
166(d) Scales, loss-of-weight recorders, liquid-level indicators, or flow meters, as appropriate, shall be provided to accurately measure quantities of fluoride chemicals used.
188(e) At each drinking water treatment plant with fluoridation facilities, the supplier of water shall provide appropriate safety or protective equipment in accordance with Table 15.5 in 215Water Treatment Plant Design 219as incorporated into Rule 22362-555.330, 224F.A.C.
225(f) Suppliers of water who fluoridate their water shall provide analytical equipment that uses the colorimetric or ion electrode method to measure the fluoride concentration in the treated water.
254(g) New or altered fluoridation facilities shall be designed and constructed in accordance with Section 4.7 and Part 5 in 274Recommended Standards for Water Works 279as incorporated into Rule 28362-555.330, 284F.A.C., and in accordance with 289Water Fluoridation: A Manual for Engineers and Technicians 297as incorporated into Rule 30162-555.330, 302F.A.C.
303(3) Quality Assurance and Reporting.
308(a) For each drinking water treatment plant fluoridating water, the supplier of water shall measure and record daily the quantity of fluoride chemical used, calculate and record daily the fluoride dose, and measure and record daily the fluoride concentration in the finished drinking water at the entry to the drinking water distribution system. The daily measurements of fluoride concentration in finished water may be performed by any authorized representative of the supplier of water but shall be performed using an appropriate method referenced in subsection 39362-550.550(1), 394F.A.C. If the daily measurements of fluoride concentration in finished water are not performed by a laboratory certified by the Department of Health to perform fluoride analyses of drinking water, the supplier of water shall collect check samples and have them analyzed in accordance with paragraph (b) below.
442(b) For each public water system (PWS) fluoridating water and not using a certified laboratory to perform all daily measurements of fluoride concentration in the finished drinking water from each of the PWS’s treatment plants, the supplier of water shall collect two check samples per month from the PWS’s distribution system. Each check sample shall be “split” into two samples, one which shall be analyzed by an authorized representative of the supplier of water and one which shall be analyzed by a laboratory of the Department of Health or a laboratory certified by the Department of Health to perform fluoride analyses of drinking water.
546(c) For each drinking water treatment plant fluoridating water, the supplier of water shall report the information required under paragraph (a) above and, if applicable, the results of the analyses required under paragraph (b) above to the Department of Health’s Bureau of Dental Health within ten days after each month of operation using Form 60062-555.900(5), 601Monthly Operation Report for PWSs Fluoridating Water, hereby adopted and incorporated by reference, effective August 28, 2003. Copies of this form are available from the Department of Environmental Protection, Drinking Water Section, M.S. 3520, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400.
642(4) The Department of Health’s Bureau of Dental Health is authorized to conduct inspections of fluoridation facilities at public water systems.
