Current through Reg. 50, No. 187; September 24, 2024
(1) Water quality
samples collected for compliance with this chapter, except chlorine residuals,
shall be analyzed by a laboratory certified for the contaminant by the
Department in accordance with Chapter 64E-1, F.A.C., and shall be analyzed
using a Department-certified method for analyzing drinking water samples.
Approved methods for analyzing drinking water compliance samples are available
at the U.S. EPA Office of Groundwater and Drinking Water website at
www.epa.gov/safewater/methods/methods.html.
Microbiological analyses shall be in accordance with those methods specified in
40 C.F.R. §
141.21(f), July 1, 2007.
Chemical analyses shall be in accordance with those methods specified in
40 C.F.R. §
141.23(k), July 1,
2007.
(2) Analysis results of water
quality samples collected for compliance with this chapter shall not exceed the
following standards:
(a) Chemical Maximum
Contaminant Levels (MCL) and Health Advisory Levels (HAL):
1. Lead - 0.015 milligrams per liter
(mg/L).
2. Nitrate as N - 10.0
mg/L.
3. Other primary drinking
water contaminant MCLs listed in Rule
62-550.310, F.A.C.
4. Drinking water HALs as defined in
subsection 64E-8.001(8),
F.A.C.
(b)
Microbiological Maximum Contaminant Levels (MCL):
1. A total coliform MCL violation occurs when
a total coliform test reveals the presence of total coliform bacteria in any
compliance and repeat sample.
2. A
fecal coliform MCL violation occurs when a fecal coliform or E. coli test
reveals the presence of fecal coliform or E. coli in any compliance or repeat
sample, provided the repeat test is positive for total coliform
bacteria.
3. The supplier shall
collect a repeat sample on the first business day following notification that
coliform bacteria were present in the previous sample. Failure to provide a
repeat sample to the laboratory by the deadline specified by the Department
will result in use of the previous sample's results as if they were the repeat
sample's results.
4. Unless
coliform bacteria are present, a result of too numerous to count (TNTC),
confluent or turbid with the absence of gas or acid, is invalid and the
supplier shall collect a replacement sample on the next business day after
notification of the invalid results.
(3) The following monitoring schedule applies
to annually permitted Limited Use Public Water Systems:
(a) Analysis of water samples for Lead and
Nitrate per paragraphs
64E-8.002(9)(c) and
(d), F.A.C., is required once every
thirty-six (36) months for Limited Use Community Systems, or once every sixty
(60) months for Limited Use Commercial Systems. Such analyses shall be
performed no more than 36 months or 60 months apart, respectively. The
Department shall require more frequent chemical monitoring if analysis results
indicate the presence of contaminants which may pose a threat to public
health.
(b) One (1) microbiological
analysis of a water sample from the distribution system is required once every
calendar quarter (one sample during each of the following periods: January
through March; April through June; July through September; October through
December). Whenever possible, each quarterly sample shall be collected during
the middle month of each period (February, May, August and November) in order
to allow time for laboratory analysis and reporting of results.
1. When treatment includes disinfection, one
(1) microbiological source water sample must also be collected on the same day
as the distribution water sample.
2. The Department may increase
microbiological analysis frequency to a monthly basis for a period of one (1)
year or more if the water source or water system has a history of intermittent
unsatisfactory microbiological analysis results.
(4) Additional analyses for contaminants
shall be required for a system if:
(a) The
well is located within a Department of Environmental Protection (DEP)
delineated area under Chapter 62-524, F.A.C.
(b) The well is within one-thousand (1, 000)
feet of a contaminated well or a known contaminant source.
(c) The analyses are required per Rule
64E-8.007,
F.A.C.
(5) All Limited
Use Public Water System suppliers shall report water sample analysis results to
the Department within five days of receipt of the results. Analysis results for
chemical samples required by paragraph (3)(a), above, must be submitted no
later than thirty (30) days after the time period in which the sample was
required. Analysis results for microbiological samples required by paragraph
(3)(b), above, must be submitted no later than fifteen (15) days after the time
period in which the sample was required. These reporting deadlines in no way
change the compliance sampling time periods in which sample analysis is
required to be performed by the supplier.
(a)
Any chemicals or pathogens detected in concentrations that exceed a published
MCL or HAL shall be reported by the supplier to the Department and removed by
corrective actions taken by the supplier per Rule
64E-8.007, F.A.C.
(b) Laboratories must report to the supplier
and to the Department all positive microbiological water sample analysis
results and any water sample analysis results that exceed a published MCL or
HAL no later than the end of the next business day after the result was
determined, by telephone, facsimile, or email. Positive fecal coliform or E.
coli results must be reported to the supplier and to the Department as soon as
possible, but no later than the end of the day in which the result was
determined in accordance with subsection
64E-1.005(2),
F.A.C.
(6) Fees charged
to the supplier when samples are submitted by or through the Department for
routine monitoring, for a well or water system clearance or for a private
request shall include laboratory analysis costs for each sample analyzed, any
locally mandated fees and shipping fees.
(7) Department staff may collect compliance
samples upon a supplier's request for a fee of $50.00 per microbiological
sampling site visit, $60.00 per chemical sampling site visit, or $70.00 per
combined chemical and microbiological sampling site visit, plus any locally
mandated fees, laboratory analysis fees and shipping fees.
