Fla. Admin. Code Ann. R. 62-555.325 - Fluoridation
(1) Fluoride levels in drinking water shall
not exceed the primary maximum contaminant level under Rule
62-550.310, F.A.C., or the
secondary maximum contaminant level under Rule
62-550.320, F.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.
(2) Equipment and
Installation.
(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).
(b) Fluoride
metering pumps shall have antisiphon protection.
(c) Tanks and containers holding
fluorosilicic acid shall be vented only to the outside atmosphere.
(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.
(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 Water
Treatment Plant Design as incorporated into Rule
62-555.330, F.A.C.
(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.
(g) New or altered
fluoridation facilities shall be designed and constructed in accordance with
Section 4.7 and Part 5 in Recommended Standards for Water
Works as incorporated into Rule
62-555.330, F.A.C., and in
accordance with Water Fluoridation: A Manual for Engineers and
Technicians as incorporated into Rule
62-555.330,
F.A.C.
(3) Quality
Assurance and Reporting.
(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 62-550.550(1),
F.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.
(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.
(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 62-555.900(5),
Monthly 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.
(4) The
Department of Health's Bureau of Dental Health is authorized to conduct
inspections of fluoridation facilities at public water
systems.
