(1) For the purpose of determining compliance
with standards and monitoring requirements other than those mentioned in
subsection (2) below, samples shall be considered acceptable only if they have
been analyzed by a laboratory certified in drinking water by the Department of
Health to perform such drinking water analyses with the exception that
measurements for alkalinity, bromide, calcium, chlorite at entrances to
distribution systems, orthophosphate, silica, specific ultraviolet absorbance,
or total organic carbon may be performed by operators licensed under Chapter
62-602, F.A.C., or by persons under the direct supervision of a licensed
operator, and measurements for conductivity, disinfectant residual, pH,
temperature, or turbidity may be performed by operators licensed under Chapter
62-602, F.A.C., by persons under the direct supervision of a licensed operator,
or by any authorized representative of the Department. Approved analytical
methods shall be used and are contained in the July 1, 2014, edition of
40 C.F.R. §§
141.21,
141.23,
141.24,
141.25,
141.27,
141.74,
141.89,
141.131,
141.402,
141.704,
141.852, and
143.4 and Appendix A to 40 C.F.R.
Part
141, Subpart C (
http://www.flrules.org/Gateway/reference.asp?No=Ref-05592),
all of which are incorporated herein by reference. Use of an alternative
analytical technique requires written permission from the Department and the
U.S. Environmental Protection Agency. The use of DPD colorimetric test kits to
measure residual chlorine, chloramine, or chlorine dioxide concentration is
approved. This subsection shall be effective on July 7, 2015.
(2) Measurements for residual disinfectant to
demonstrate that TTHM and HAA5 samples were taken under normal operating
conditions (see subsection
62-550.821(4),
F.A.C.) and measurements for disinfectant residual to determine compliance with
the operational requirements in subsection
62-555.350(6),
F.A.C., may be performed by any authorized representative of the supplier of
water or the Department; but measurements for residual chlorine shall be
performed following the appropriate procedures in the Department of
Environmental Protection Standard Operating Procedures for Field Activities,
DEP-SOP-001/01, as incorporated into Rule
62-160.800, F.A.C., and all
other measurements shall be performed using an appropriate method referenced in
subsection (1) above. Measurements for alkalinity, dissolved iron, dissolved
oxygen, pH, total sulfide, or turbidity to evaluate treatment for control of
copper pipe corrosion and black water (see subsection
62-555.315(5),
F.A.C.) may be performed by any authorized representative of the construction
permit applicant or supplier of water; but measurements for pH and field
measurements for dissolved oxygen or turbidity shall be performed following the
appropriate procedures in the Department of Environmental Protection Standard
Operating Procedures for Field Activities, DEP-SOP-001/01, as incorporated into
Rule
62-160.800, F.A.C., and all
other measurements shall be performed using an appropriate method referenced in
subsection (1) above or in
Standard Methods for the Examination of
Water and Wastewater as adopted in Rule
62-555.335, F.A.C. Measurements
for residual chlorine when taking bacteriological survey or evaluation samples
(see paragraphs
62-555.315(6)(b) and
(c), F.A.C., and subsection
62-555.340(2),
F.A.C.) may be performed by any authorized representative of the permittee,
supplier of water, or Department, but shall be performed following the
appropriate procedures in the Department of Environmental Protection Standard
Operating Procedures for Field Activities, DEP-SOP-001/01, as incorporated into
Rule
62-160.800, F.A.C. Daily
measurements for fluoride concentration at water treatment plants fluoridating
water (see paragraph
62-555.325(3)(a),
F.A.C.) may be performed by any authorized representative of the supplier of
water but shall be performed using an appropriate method referenced in
subsection (1) above. Measurements for disinfectant residual, pH, or
temperature to determine compliance with the operational requirements under
subsection
62-555.350(5),
F.A.C., may be performed by any authorized representative of the supplier of
water or Department; but measurements for residual chlorine, temperature, or pH
shall be performed following the appropriate procedures in the Department of
Environmental Protection Standard Operating Procedures for Field Activities,
DEP-SOP-001/01, as incorporated into Rule
62-160.800, F.A.C., and all
other measurements shall be performed using an appropriate method referenced in
subsection (1) above or in
Standard Methods for the Examination of
Water and Wastewater as adopted in Rule
62-555.335, F.A.C.
(3) The Department may take samples and use
the results to determine compliance with the applicable requirements of this
chapter or Chapter 62-555, F.A.C.
(4) Compositing of Samples.
(a) A public water system may reduce the
total number of samples that must be analyzed pursuant to Rules
62-550.511,
62-550.512,
62-550.513,
62-550.515,
62-550.516, and
62-550.519, F.A.C., by the use
of compositing. No more than two samples shall be combined into one composite
sample when analyzing for antimony or thallium, which are listed in Table 1, or
for any of the volatile organic contaminants listed in Table 4, or for ethylene
dibromide (EDB), which is listed in Table 5. No more than three samples shall
be combined into one composite sample when analyzing for toxaphene, which is
listed in Table 5. No more than four samples shall be combined into one
composite sample when analyzing for cyanide, which is listed in Table 1. No
more than five samples shall be combined into one composite sample when
analyzing for the other contaminants in the other groups.
(b) Compositing shall be done only by
certified laboratories using the approved methods referenced in subsection (1)
above. All samples, except those taken for radionuclides, shall be analyzed
within 14 days of collection.
(c)
If the population served by the system is greater than 3, 300 persons, then
compositing is only permitted at sampling points within a single system. For
systems serving 3, 300 or fewer persons, compositing among different systems is
permitted provided the 5 sample limit is maintained.
(d) Resampling After a Detection of a
Contaminant in a Composite Sample.
1. A
follow-up sample shall be taken within 14 days from each source and sampling
point included in the composite. Each of the samples shall be analyzed
individually for the detected contaminant.
2. If duplicates of the original sample for
volatile or synthetic organic contaminants are available, the system may use
these duplicates instead of resampling. If a duplicate is used, it shall be
analyzed for the detected contaminant within 14 days of
collection.
(e)
Compositing of no more than two samples from new wells for the purpose of
obtaining clearance is allowed.
