62- 550.102 Intent and Scope.
(1) To assure that public water systems supply drinking water which meets
minimum requirements, the Federal Government enacted PL 93 -523, the "Safe Drinking
Water Act." The scheme of that law was to give primary responsibility for public water
systems programs to states to implement a public water system program. Also, the
legislature of Florida has enacted the "Florida Safe Drinking Water Act," sections
403.850- 403.864, F.S. This chapter and chapters 62 -555 and 62 -560, F.A.C., are
promulgated to implement the requirements of the Florida Safe Drinking Water Act and
to acquire and maintain primacy for Florida under the Federal Act. This chapter and
chapter 62 -555 and 62 -560, F.A.C., adopt national primary and secondary drinking
water standards of the Federal Government where possible, and otherwise create
additional rules to fulfill state and Federal requirements.
(2) The Safe Drinking Water Act and the Florida Safe Drinking Water Act
exclude certain public water systems from coverage. The drinking water rules in
chapters 62 -550, 62 -555, and 62 -560, F.A.C., apply to all public water systems except
those which meet all of the following criteria:
(a) Consist of distribution and storage facilities only and do not have any
collection or treatment facilities;
(b) Obtain all water from, but are not owned or operated by, a public water
system to which such rules apply;
(c) Do not sell water to any person; and
(d) Are not carriers which convey passengers in interstate commerce.
(3) For the purpose of subsection (2) above, the phrase "sell water to any
person" shall mean distribute water to land owned by another person as well as bill
separately or specifically for the water. Also, for the purpose of subsection (2) above,
the phrase "treatment facilities" shall exclude treatment facilities that are not necessary
to achieve, and will not adversely affect, compliance with applicable drinking water
standards and requirements.
(4) This chapter sets the drinking water standards, monitoring requirements,
and treatment techniques to be met by public water systems and the testing protocol
required for certified laboratories.
(5) Chapter 62 -555, F.A.C., sets the permitting requirements for public water
systems including the location and construction of wells serving the system and the
treatment plant. Construction of public water systems require permits and the use of
lead free pipes, plumbing fixtures, solder and flux. General permits for public water
systems are included. Engineering references are listed.
(6) Chapter 62 -560, F.A.C., gives the description of the violations of Chapters
62 -550, 62 -555, and 62 -560, F.A.C., and the resulting penalties. In addition, this chapter
Effective 2 -16 -12
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
describes public notification requirements for public water systems that do not meet
applicable maximum contaminant levels, maximum residual disinfectant levels, and treat
technique requirements; do not meet applicable monitoring requirements; or have a
variance or exemption. This chapter also describes the availability and processes for
receiving variances, exemptions, and waivers. Additionally, Best Available Technology
is listed for various contaminants and disinfectant residuals.

NOTE: Section 381.261, F.S., gives general supervision and control over all private
water systems and public water systems not covered or included in the Florida Safe
Drinking Water Act to the Department of Health (DOH). The Department interprets this
as meaning that DOH has supervision and control of all water systems which meet all of
the four exception criteria and which also have at least 15 service connections or which
regularly serve at least 25 individuals daily at least 60 days out of the year. The
Department also interprets Section 381.261, F.S., as meaning that DOH has
supervision and control of all water systems that have less than 15 service connections
or which regularly serve less than 25 individuals daily at least 60 days out of the year, or
at least 25 individuals daily less than 60 days out of the year.

the distribution system and no two consecutive daily samples exceed the MRDL.
MRDLs are enforceable in the same manner as maximum contaminant levels under the
Florida Safe Drinking Water Act. However, there is convincing evidence that addition of
a disinfectant is necessary for control of waterborne microbial contaminants. Therefore,
notwithstanding the MRDLs listed in subsection 62- 550.310(2), F.A.C., operators may
increase residual disinfectant levels of chlorine or chloramines (but not chlorine dioxide)
in the distribution system to a level, and for a time, necessary to protect public health to
address specific microbiological contamination problems caused by circumstances such
as distribution line breaks, storm runoff events, source water contamination, or cross
connections.

people.
(60) "NEAR THE FIRST SERVICE CONNECTION" means at one of the 20
percent of all service connections in the entire system that are nearest the water supply
treatment facility, as measured by water transport time within the distribution system.
(61) "NEW SYSTEM" means, for the purposes of capacity development,
community water systems or non - transient non - community water systems being newly
constructed; systems which do not currently meet the definition of a public water system
under Rule 62- 550.200(70), but which expand their infrastructure and thereby grow to
become community water systems or non - transient non - community water systems; and
transient non - community systems that expand their infrastructure and thereby grow to
become community water systems or non - transient non - community water systems.

or systems that are transient non - community systems, and that add additional users
and thereby become community water systems or non - transient non - community water
systems without constructing any additional infrastructure are not "new systems" for
purposes of capacity development.
(62) "NON- COMMUNITY WATER SYSTEM" means a public water system that
is not a community water system. A non - community water system is either a "transient
non - community water system" (TWS) or a "non- transient non - community water system"
(NTNCWS). See Code of Federal Regulations (C.F.R.), title 40, part 141, section 2.
Other public water systems are addressed in Chapter 64E -8, F.A.C.

QUALITY STANDARDS
62- 550.300 Application of Quality Standards to Public Water Systems.
The ultimate concern of the public water system supervision program is the quality of
water for human consumption when the water reaches the consumers. The following
rules establish maximum contaminant levels (MCLs) and maximum residual disinfectant
levels (MRDLs) for water within public water systems. Additionally, these rules
establish treatment technique requirements in lieu of, or in addition to, MCLs for certain
contaminants. Public water systems shall comply with the MCLs, MRDLs, and
treatment technique requirements established herein unless granted a variance or
exemption pursuant to Rule 62- 560.510 or 62- 560.520, F.A.C., or unless identified as
excluded from the MCLs, MRDLs, or treatment technique requirements by this chapter.
Public water systems shall take necessary corrective action approved by the
Department to meet all applicable MCLs, MRDLs, and treatment technique
requirements.

Levels and Maximum Residual disinfectant Levels.
(These standards may also apply as ground water quality standards as referenced in
Chapter 62 -520, F.A.C.)
(1) INORGANICS - Except for nitrate and nitrite, which apply to all public
water systems, this subsection applies to community water systems and non - transient
non - community water systems only.
(a) The maximum contaminant levels for the inorganic contaminants are listed
in Table 1, which is incorporated herein and appears at the end of this Chapter.
(b) The maximum contaminant level for nitrate (as N) applicable to transient
non - community water systems is 10 milligrams per liter. The Department or Approved
County Public Health Department shall allow a contaminant level for nitrate (as N) of up
to 20 milligrams per liter upon a showing by the supplier of water that the following
conditions are met:
1. The water distributed by the water system is not available to children
under 6 months of age or to lactating mothers, and
2. There is continuous public notification of what the nitrate level (as N) is
and the potential health effects of such exposure are.
3. The Department shall require monitoring every 3 months as long as the
maximum contaminant level is exceeded. Should adverse health effects occur, the
Department shall require immediate compliance with the maximum contaminant level
for nitrate (as N).
(c) The revised maximum contaminant level of 0.010 mg /L for arsenic
becomes effective January 1, 2005. All community and non - transient non - community
water systems shall demonstrate compliance with the revised maximum contaminant
level by December 31, 2007.
(2) DISINFECTANT RESIDUALS — Except for the chlorine dioxide maximum
residual disinfectant level, which applies to all public water systems using chlorine
dioxide as a disinfectant or oxidant, this subsection applies only to community or non -
transient non - community water systems adding a chemical disinfectant to the water in
any part of the drinking water treatment process. Maximum residual disinfectant levels
(MRDLs) are listed in Table 2, which is incorporated herein and appears a the end of
this chapter.
(3) DISINFECTANT BYPRODUCTS — This subsection applies to all
community or non - transient non - community water systems adding a chemical
disinfectant to the water in any part of the drinking water treatment process. The Stage
1 maximum contaminant levels (MCLs) for disinfection byproducts are listed in Table 3,
which is incorporated herein and appears at the end of this chapter.

(a) The maximum contaminant levels for the volatile organic contaminants
(VOCs) are listed in Table 4, which is incorporated herein and appears at the end of this
chapter. The regulatory detection limit (RDL) for all VOCs is 0.0005 mg /L.
(b) The maximum contaminant levels and the regulatory detection limits
(RDLS) for the synthetic organic contaminants (SOCs) are listed in Table 5, which is
incorporated herein and appears at the end of this chapter.
(5) MICROBIOLOGICAL - This subsection applies to all public water systems.
Monitoring requirements to demonstrate compliance with this subsection are defined in
Rule 62- 550.518, F.A.C.
(a) The maximum contaminant level is based on the presence or absence of
total coliforms in a sample, rather than coliform density. For the purpose of the public
notice requirements in Rule 62- 560.410, F.A.C., a violation of the standards in this
paragraph poses a non -acute risk to health.
1. For a system which collects at least 40 samples per month, if no more
than 5.0 percent of the samples collected during a month are total coliform- positive, the
system is in compliance with the maximum contaminant level for total coliforms.
2. For a system which collects fewer than 40 samples per month, if no more
than one sample collected during a month is total coliform- positive, the system is in
compliance with the maximum contaminant level for total coliforms.
(b) Any fecal coliform- positive repeat sample or E.co/i- positive repeat sample,
or any total coliform- positive repeat sample following a fecal coliform- positive or E.coli-
positive routine sample is a violation of the maximum contaminant level for total
coliforms. For the purposes of the public notification requirements in Rule 62- 560.410,
F.A.C., this is a violation that poses an acute risk to health.
(c) A public water system shall determine compliance with the maximum
contaminant level for total coliforms in paragraphs (a) and (b) or this subsection for each
month (or quarter for transient non - community water systems that use only ground
water not under the direct influence of surface water and that serve 1,000 or fewer
persons) in which it is required to monitor for total coliforms.

PART V
MONITORING REQUIREMENTS
62- 550.500 General Monitoring and Compliance Measurement
Requirements for Contaminants and Disinfectant Residuals.
These general requirements shall apply unless other monitoring or compliance
measurement requirements are specified in Rules 62- 550.511 through 62- 550.540,
F.A.C., or Rule 62- 550.821, F.A.C.
(1) The Monitoring Framework. Monitoring by public water systems shall be
accomplished within a standardized monitoring framework developed to address the
issues of complexity, coordination between various rules, and coordination of monitoring
schedules. A compliance cycle is a nine -year period during which all public water
systems must monitor. Compliance cycles begin January 1, 2002, and January 1,
2011, and every nine years thereafter. Each compliance cycle is broken down into
three three -year compliance periods. For example, the three compliance periods that
make up the 2002 through 2010 compliance cycle begin January 1, 2002, January 1,
2005, and January 1, 2008.
(2) Monitoring Frequencies. Monitoring frequencies for each group of
contaminants or disinfectant residuals are specified in Rules 62- 550.511 through 62-
550.520, F.A.C. plus Rule 62- 550.821, F.A.C., and are summarized in Table 7.
(3) Monitoring Schedule. Each public water system shall monitor at the time
designated by this subsection during each compliance cycle and compliance period.
Table 8 summarizes when public water systems shall perform initial or routine
monitoring.
(a) Systems that monitor for a contaminant quarterly may do so any time
during the quarter, except that samples taken in consecutive quarters shall be taken at
least 30 days apart.
(b) Systems that monitor for a contaminant annually may do so any time
during the year, except that samples taken in consecutive years shall be taken at least
90 days apart.
Effective 2 -16 -12
20
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
(c) Systems that monitor for a contaminant every three years shall adhere to
the following schedule:
1. Community water systems which serve more than 3,300 persons shall
monitor during the first year of each compliance period.
2. Community water systems which serve 3,300 or fewer persons shall
monitor during the second year of each compliance period.
3. Non - transient non - community water systems shall monitor during the third
year of each compliance period.
(d) Systems that monitor for a contaminant every six years shall monitor as
directed by the Department.
(e) Systems that monitor for a contaminant every nine years shall monitor
during the first three -year compliance period of each nine -year compliance cycle
following the same schedule as in paragraph (c) above.
(f) In the event the population of a small community system increases to
more than 3,300 persons, the system shall continue to monitor on the schedule
originally prescribed in paragraphs (c) and (d) above for the remainder of the nine -year
compliance cycle. At the beginning of the next nine -year compliance cycle, the system
shall begin monitoring in the prescribed year according to its then current size or
classification.
(g) Upon request, small community systems and non - transient non -
community systems shall be approved to monitor earlier during compliance periods or
cycles than required by paragraphs (c) through (e) above.
(4) Increased Monitoring. When specified by the State Health Officer, the
Department shall require more frequent monitoring than specified in this section and
shall require confirmation samples results as needed to protect public health.
(5) Monitoring Locations.
(a) Ground water systems and subpart H systems shall take a minimum of
one sample at every entry point to the distribution system that is representative of each
source after treatment (hereafter called a sampling point). The system shall take each
sample at the same sampling point unless conditions make another sampling point
more representative of each source or treatment plant.
(b) For purposes of Part V of this chapter, subpart H systems also include
systems using a combination of surface water (or ground water under the direct
influence of surface water) and ground water not under the direct influence of surface
water.
(c) If a system draws water from more than one source and the sources are
combined before distribution, the system must sample at an entry point to the
distribution system during periods of typical operating conditions (e.g., when water is
representative of the sources being used).
(6) Confirmation Samples. The system shall take confirmation samples
whenever a sample exceeds the maximum contaminant level for nitrate or nitrite and
whenever an unregulated contaminant is detected. However, a system may take
confirmation samples for other inorganic contaminants, organic contaminants,
radionuclides, or secondary contaminants. For regulated contaminants, the results of
confirmation samples shall be averaged with the first sampling results and the average
Effective 2 -16 -12
21
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
used for the compliance determination as specified by subsection (7) below.
Confirmation samples shall be collected at the same sampling point as soon as
possible, but not later than two weeks, after the initial sample was taken. The
Department shall delete results of obvious sampling errors from this calculation.
(7) Measurement of Compliance. Compliance with Rule 62- 550.310, F.A.C.,
shall be determined based on the analytical results obtained at each sampling point. If
one sampling point is in violation of an MCL, the system is in violation of the MCL.
(a) For systems that are taking more than one sample per year, compliance is
determined by a running annual average of all samples taken at each sampling point. If
the running annual average of any sampling point is greater than the maximum
contaminant level, then the system is out of compliance. If the initial sample or a
subsequent sample would cause the running annual average to be exceeded, then the
system is immediately out of compliance. Any sample results which are below the
regulatory detection limit shall be calculated as zero for purposes of determining the
running annual average. If a system fails to collect the required number of samples,
compliance with the MCL will be based on the total number of samples collected.
Systems shall include all samples, taken within a quarter and analyzed under the
provisions of this section (even if that number is greater than the minimum required), to
obtain an average for the quarter to determine compliance with these rules.
(b) A system monitoring annually or less frequently for the inorganic
contaminants, other than nitrate or nitrite, listed in subsection 62- 550.310(1), F.A.C., the
volatile organic contaminants listed in paragraph 62- 550.310(4)(a), F.A.C., the synthetic
organic contaminants listed in paragraph 62- 550.310(4)(b), F.A.C., or the radiological
contaminants listed in subsection 62- 550.310(6), F.A.C., whose sample result exceeds
the maximum contaminant level will not be considered in violation of the maximum
contaminant level until it has completed one year of quarterly sampling. If the running
annual average of any sampling point is greater than the maximum contaminant level,
then the system is out of compliance. If the initial sample or a subsequent sample
would cause the running annual average to exceed the maximum contaminant level,
then the system is immediately out of compliance. For the purpose of calculating the
running annual average, the initial exceedance is considered to be the first quarterly
sample. Any sample result that is below the regulatory detection limit shall be
calculated as zero for purposes of determining the running annual average. If a system
fails to collect the required number of samples, compliance with the MCL will be based
on the total number of samples collected. Rule 62- 550.512, F.A.C., governs nitrate and
nitrite, which are considered acute contaminants.
(c) The Department shall delete results of obvious sampling or analytic errors.
(8) Systems Not in Compliance with a Maximum Contaminant Level (MCL or
Maximum Residual Disinfectant Level (MRDL). A system that is not in compliance with
an MCL or MRDL shall notify the Department within 48 hours of receiving the results
(except for violations of the microbiological, nitrate, or nitrite MCL and acute violations of
the MRDL for chlorine dioxide), and notify the public in accordance with Rule 62-
560.410, F.A.C.

(9) Waivers from Monitoring. Systems may request to receive a waiver from
the requirement to monitor for organic contaminants pursuant to Rule 62- 560.545,
F.A.C.
(10) Reporting the results of analyses. All public water systems shall forward
the results of analyses to the Department pursuant to Rule 62- 550.730, F.A.C.
(11) New Systems or Sources. All new systems or systems that use a new
source of water shall demonstrate compliance with all maximum contaminant levels.
The system shall comply with the initial sampling frequencies as specified in this
chapter. Routine and increased monitoring frequencies shall be conducted in
accordance with the requirements in this chapter.

(5) The Department shall reduce the monitoring frequency to annually, for
systems that exceeded the maximum contaminant level for asbestos and are required
to monitor quarterly as prescribed by subsection 62- 550.500(8), F.A.C., if the running
annual average is below the maximum contaminant level. The Department shall reduce
the monitoring frequency as provided in paragraph 62- 550.500(3)(d), F.A.C., when the
average of three consecutive years of monitoring results is less than 50% of the
maximum contaminant level and no sample exceeds the maximum contaminant level.

of surface water are required by subsections 62- 550.518(2), (3), and (10), F.A.C., to
periodically sample the raw ground water for microbiological contamination. In the
event a raw water sample is positive for total coliform bacteria, the system shall begin
monitoring the raw water source for turbidity, pH, temperature, nitrates, and conductivity
when notified in writing by the Department to do so and shall perform a microscopic
particulate analysis and particle counter analysis when notified in writing by the
Department to do so. These data will be used by the Department to determine whether
the system's water source is under the direct influence of surface water. If the
Department renders a written decision that the source is not under the direct influence
of surface water, or if no subsequent raw water samples are positive for bacteria during
the following one -year period, monitoring of the raw water for turbidity, pH, temperature,

and conductivity will no longer be required. If the Department determines that a system
is under the direct influence of surface water, the system shall comply with Rule 62-
550.817, F.A.C. In the event the system notifies the Department in writing that it
disagrees with the Department's determination, the system shall have six months in
which to commission and complete an independent analysis of the system. Upon
receipt of such an independent analysis, the Department will reconsider its
determination and notify the system of its decision and include the notice of rights to an
administrative hearing as provided in Rule 62- 110.106, F.A.C.

62- 550.518 Microbiological Monitoring Requirements.
(1) All public water systems shall analyze for coliform bacteria to determine
compliance with subsection 62- 550.310(5), F.A.C. Public water systems shall collect
total coliform samples at sites that are representative of water throughout the
distribution system and in accordance with a written sampling plan that addresses
location, timing, frequency, and rotation period. These plans shall be available for
review and possible revision on the occasion of a sanitary survey conducted by the
Department. Descriptions of sampling locations shall be specific, i.e., numbered street
addresses or lot numbers. Pressure tank or plant tap samples are not acceptable for
determining compliance.
(2) Total coliform samples shall be taken at regular intervals and in numbers
proportionate to the population served by the system. Community water systems, non -
transient non - community water systems, transient non - community water systems that
are subpart H systems and transient non - community water systems that serve more
than 1,000 persons per day during any one month shall take monthly distribution system
samples. In addition, systems that are using ground water not under the direct
influence of surface water shall take a minimum of one monthly raw water sample that is
representative of each ground water source (i.e., well) not under the direct influence of
surface water. For purposes of this subsection, consecutive systems that receive any
finished water originating from a subpart H system are considered subpart H systems.
In no event shall the number of distribution system samples be less than as set forth

(3) Transient non - community water systems using only ground water not
under the direct influence of surface water and serving 1,000 or fewer persons shall
monitor at the rate of two distribution system samples in each calendar quarter during
which the system provides water to the public. In addition, such systems shall take a
minimum of one quarterly raw water sample that is representative of each ground water
source (i.e., well).
(4) Public water systems shall collect distribution system samples at regular
intervals throughout the month, except that a system that uses only ground water not
under the direct influence of surface water and that serves 4,900 persons or fewer may
collect all required samples on a single day if the samples are taken from different sites.
(5) Subpart H systems in an interim period per subparagraph 62-
550.817(2)(a)2., F.A.C., until filtration is installed in compliance with 40 CFR 141,
subpart H, adopted by Rule 62- 550.817, F.A.C., shall collect at least one total coliform
sample near the first service connection each day the turbidity level of the source water
exceeds one NTU, measured as specified in 40 CFR 141.74(b)(2), adopted by Rule 62-
550.817, F.A.C. This sample shall be analyzed for the presence of total coliforms.
When any turbidity measurement in any day exceeds one NTU, the system shall collect
this coliform sample within 24 hours unless the Department determines that the system,
for logistical reasons outside the system's control, cannot have the sample analyzed
within 30 hours of collection. In this case, the Department shall specify how much time
the system has to collect the sample. Sample results from this coliform monitoring shall
be included in determining compliance with the maximum contaminant level for total
coliforms in subsection 62- 550.310(5), F.A.C.
(6) Special purpose samples, such as those taken to determine whether
disinfection practices are sufficient following pipe placement, replacement, or repair,
shall not be used to determine compliance with the maximum contaminant level for total
coliforms in subsection 62- 550.310(5), F.A.C. Repeat distribution system samples
taken pursuant to subsection (7) of this section are not considered special purpose
samples, and shall be used to determine compliance with the maximum contaminant
level for total coliforms in subsection 62- 550.310(5), F.A.C.
(7) Additional or Repeat Monitoring.
(a) If a raw water sample is total - coliform- positive, the public water system
shall disinfect and bacteriologically survey the relevant well(s) in accordance with
subsection 62- 555.315(6), F.A.C., when notified in writing by the Department to do so
and shall conduct physical characteristics monitoring in accordance with subsection 62-
550.517(2), F.A.C., when notified in writing by the Department to do so.
(b) If a routine distribution system sample is total - coliform - positive, the public
water system shad collect a set of repeat distribution system samples within 24 hours of
being notified of the positive result.'The system shall collect all repeat samples on the''
same day. A system that collects monthly routine samples shall collect no fewer tharii
three repeat samples for each total - coliform- positive sample fourv. A transient non -
community water system that collects quarterly routine samples shall collect no fewer
than four repeat samples for each total - coliform- positive sample found. The
Department shall extend the 24 -hour limit on a case -by -case basis if the system has a;
logistical problem, that is beyond its control in collecting the repeat samples within 24
Effective 2 -16 -12
31
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
hours. If an extension is granted, the Department shall specify how much time the
system has to collect the repeat samples. If a routine distribution system sample is
total - coliform- positive and the public water system is collecting fewer than five routine
distribution system samples per month, the system also shall comply with the sampling`
requirements in subsection 62- 550.518(8), F.A.C.,
(c) The system shall collect at least one repeat distribution system sample
from the sampling tap where the original total - coliform- positive sample was taken, at
least one repeat distribution system sample at a tap within five service connections
upstream of the original sampling site, and at least one repeat distribution system
sample at a tap within five service connections downstream of the original sampling site.
If a total - coliform- positive sample is at the beginning or end of the distribution system, or
one service connection away from the beginning or end of the distribution system, the
system need not collect a repeat sample upstream or downstream of the original
sampling site, whichever is applicable, but still must collect the total number of repeat
samples specified in paragraph (b) above.
(d) If any repeat distribution system sample in the set is total - coliform- positive
the public water system shall collect an additional set of repeat distribution system
samples in the manner specified in paragraphs (7)(b) and (7)(c) of this section. The
public water system shall collect the additional samples within 24 hours of being notified
of the positive result unless the Department extends the limit as provided in paragraph
(7)(b) of this section. The system shall repeat this process until either total coliforms are
not detected in one complete set of repeat samples or the system determines that the
maximum contaminant level for total coliforms in subsection 62- 550.310(5), F.A.C., has
been exceeded and notifies the Department in accordance with subsections (10) and
(11) below.
(e) Results of all routine and repeat distribution system samples not
invalidated by the Department shall be included in determining compliance with the
maximum contaminant level for total coliforms in subsection 62- 550.310(5), F.A.C.
(8) If a system collecting fewer than five routine distribution system samples
per month has one or more total - coliform- positive samples and the Department does
not invalidate the sample(s) under paragraph 62- 550.518(9)(a), F.A.C., it shall collect at
least five routine distribution system samples during the next month the system provides
water to the public.
(9) Invalidation of Total Coliform Samples. A total -co liform- positive sample
invalidated under this subsection does not count toward meeting the minimum
monitoring requirements of this 'section Department invalidation of a total- coliform-
positive sample invalidates subsequent fecal - coliform or E. -coli- positive results on the
same sample.
(a) The Department shall invalidate a total - coliform- positive sample only if anyt
of the following conditions are met:
1. The laboratory establishes that improper sample analysis caused the total
coliform- positive result.
2. The Department, on the basis of the results of the repeat distribution
system samples collected as required by subsection (7) of this section, determines that`
the total - coliform- positive sample resulted from a non - distribution system plumbing,?
Effective 2 -16 -12
;'_
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
problem. The Department shall not invalidate a sample on the basis of repeat samples
unless all repeat samples collected at the same tap as the original total - coliform - positive
sample are also total - coliform- positive and all repeat samples collected within five'
service connections of the original tap are total - coliform- negative. The Department shal�
not invalidate a total - coliform- positive sample on the basis of repeat samples if all the y
repeat samples are total - coliform- negative or if the public water system has only one
service connection.
3. The Department has received in writing substantial grounds to conclude
that a total - coliform- positive result is due to a circumstance or condition that does not
reflect raw water quality or water quality in the distribution system. In this case, the
system shall still collect all repeat distribution system samples required under
subsection (7) of this section and use them to determine compliance with the maximum
contaminant level for total coliforms in subsection 62- 550.310(5), F.A.C. The written
documentation shall describe the specific cause of the total - coliform- positive sample
and what action the system has taken, or will take, to correct this problem. The
Department shall not invalidate a total - coliform- positive sample solely on the grounds
that all repeat samples are total - coliform- negative.
(b) Unless total coliforms are detected, a laboratory shall invalidate a total
coliform sample if the sample produces a turbid culture in the absence of gas production
using an analytical method where gas formation is examined (e.g., the Multiple -Tube
Fermentation Technique); produces a turbid culture in the absence of an acid reaction
in the Presence - Absence (P -A) Coliform Test; or, exhibits confluent growth or produces
colonies too numerous to count with an analytical method using a membrane filter (e.g.,
Membrane Filter Technique). If a laboratory invalidates a sample because of such
interference, the system shall report to the Department in accordance with subsection
62- 550.730(1), F.A.C., and collect another sample from the same location as the
original sample within 24 hours of being notified of the interference problem. The
system shall continue to resample every 24 hours and have the samples analyzed until
it obtains a valid result. The Department shall expand the 24 -hour requirement on a
case -by -case basis if the system has a logistical problem that is beyond its control in
collecting the repeat samples within 24 hours. If an extension is granted, the
Department shall specify how much time the system has to collect the repeat samples.
(10) Fecal Coliforms /Escherichia coli (E. coli) Testing. If any raw water sample
is total - coliform- positive, the system shall analyze that total - coliform- positive culture to
determine if E. coli is present. If any routine or repeat distribution system sample is
total - coliform- positive, the system shall analyze that total - coliform- positive culture to
determine if fecal coliforms are present or shall analyze that total - coliform- positive
culture to determine if E. coli is present. If fecal coliform or E. coli is present in any
repeat distribution system sample, the system shall notify the Department in accordance
with paragraph (11)(a) below. If fecal coliforms or E. coli is present in any routine
distribution system sample or if E. coli is present in any raw water sample that is
representative of a well previously considered to be meeting the bacteriological
requirements in subsection 62- 555.315(6), F.A.C., the system shall notify the
appropriate Department of Environmental Protection (DEP) District Office or appropriate
Approved County Health Department (ACRD) by the end of the day that the system
Effective 2 -16 -12
33
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
learns of the test result unless the system learns of the result after the appropriate DEP
District Office or appropriate ACHD is closed, in which case the system shall notify the
appropriate DEP District Office of appropriate ACHD before the end of the next
business day.
(11) Response to Violation.
(a) A public water system that has an acute violation of the total coliform
maximum contaminant level (MCL) as specified in paragraph 62- 550.310(5)(b), F.A.C.,
shall report the violation to the Department as soon as practicable but no later than 24
hours after the system learns of the violation and shall notify the public in accordance
with Rule 62- 560.410, F.A.C. A public water system that has a non -acute violation of
the total coliform MCL as specified in paragraph 62- 550.310(5)(a), F.A.C., shall report
the violation to the Department no later than the end of the next business day after it
learns of the violation, and shall notify the public in accordance with Rule 62- 560.410,
F.A.C.
(b) A public water system that has failed to comply with a coliform monitoring
requirement shall report the monitoring violation to the Department within 48 hours after
the system discovers the violation, and shall notify the public in accordance with Rule
62- 560.410, F.A.C.

62- 550.519 Radionuclides Monitoring Requirements.
This section contains monitoring frequency and compliance requirements for
radionuclides for community water systems.
(1) Monitoring and Compliance Requirements for Gross Alpha Particle
Activity, Radium -226, Radium -228, and Uranium.
(a) Community water systems (CWSs) shall conduct monitoring to determine
compliance with paragraph 62- 550.310(6)(a), F.A.C.
1. All existing CWSs shall sample at every entry point to the distribution
system under normal operating conditions.
2. All new community water systems or community water systems that use a
new source of water shall begin to conduct initial monitoring for the new source within
the first quarter after initiating use of the source.
3. The conversion factor for converting uranium results expressed in pCi /L to
ug /L is 1.50 ug /pCi. When converting uranium results expressed in ug /L to pCi /L, use
pCi /ug.
4. Compliance and reduced monitoring frequencies shall be calculated based
on the analytical results. The analytical result is the number that the laboratory reports,
not including (i.e., not adding or subtracting) the standard deviation.
(b) Initial monitoring: Systems shall conduct initial monitoring for gross alpha
particle activity, radium -226, radium -228, and uranium as follows:
1. Systems shall collect four consecutive quarterly samples at all sampling
points. Systems serving more than 3,300 people shall begin sampling January 1, 2005.
Effective 2 -16 -12
34
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
Systems serving 3,300 or fewer people shall begin sampling January 1, 2006. New
systems and new plants will begin monitoring as directed by the Department.
2. For gross alpha particle activity, uranium, radium -226, and radium -228
monitoring, the Department shall waive the final two quarters of initial monitoring for a
sampling point if the results of the samples from the previous two quarters are below the
regulatory detection limit.
3. If the average of the initial monitoring results for any sampling point is
above the MCL, the system is out of compliance. The system must continue to collect
and analyze quarterly samples at the sampling point until the system has results from
four consecutive quarters that are at or below the MCL, unless the system enters into
another schedule as part of a formal compliance agreement with the Department.
4. During the initial monitoring period, if the average of the results for a given
contaminant is above half the MCL but at or below the MCL, systems serving more than
3,300 people shall sample again for that contaminant during 2008. Systems serving
3,300 or fewer people shall sample again during 2009.
5. During the initial monitoring period, if the average of the results for a given
contaminant is at or above the regulatory detection limit but at or below half the MCL,
systems serving more than 3, 300 people shall sample again for that contaminant
during 2011. Systems serving 3,300 or fewer people shall sample again during 2012.
6. Systems serving more than 3,300 people that are required to sample
during the initial monitoring period and have no detections shall sample again during
2014. Systems serving 3,300 or fewer people that are required to sample during the
initial monitoring period and have no detections shall sample again during 2015.
(c) Use of Historical Data. Under the following conditions, data gathered
between June 1, 2000, and December 8, 2003, may be used to satisfy the requirement
to monitor during the initial monitoring period described in paragraph 62- 550.519(1)(b),
F.A.C., above.
1. The water system shall have at least one sample result from every point of
entry for gross alpha and radium -228;
2. The gross alpha result shall not exceed 15 pCi /L;
3. The system must either sample for radium -226 or may substitute the gross
alpha value if it is less than 5 pCi /L. If the gross alpha particle activity result is less than
the regulatory detection level of 3 pCi /L, half the detection level (1.5 pCi /L), shall be
used if substituting for radium -226; and
4. The combined value for radium -226 and radium -228 shall not exceed 5
pCi /L.
5. Systems that use historical data gathered between June 1, 2000, and
December 8, 2003, in lieu of testing during the initial monitoring period do not need to
monitor again until 2008 for systems serving 3,300 or more people, and 2009 for
systems serving fewer than 3,300 people.
(d) Routine monitoring begins January 1, 2008, for community water systems
serving 3,300 or more people. Community water systems serving fewer than 3,300
people begin monitoring January 1, 2009. Routine monitoring will take place every
three years and must meet the following conditions:
Effective 2 -16 -12
35
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
1. The water system shall have at least one sample result from every point of
entry for gross alpha and radium -228.
2. The gross alpha result shall not exceed 15 pCi /L. The system may either
sample for uranium or may substitute the gross alpha value if it is less than 15 pCi /L. If
the gross alpha value exceeds 15 pCi /L, the system must sample for uranium. The
uranium result shall be subtracted from the gross alpha result in order to determine
compliance with the gross alpha MCL. In the event the gross alpha result minus the
uranium result exceeds 15 pCi /L, the system shall begin quarterly monitoring for gross
alpha.
3. The uranium value shall not exceed 30 ug /L (20 pCi /L). In the even the
uranium value exceeds 30 ug /L (20 pCi /L), the system shall begin quarterly monitoring
for uranium.
4. The system must either sample for radium -226 or may substitute the gross
alpha value if it is less than 5 pCi /L. If the gross alpha value result is less than the
regulatory detection level of 3 pCi /L, half the detection level (1.5 pCi /L) shall be used if
substituting for radium -226.
5. The combined value for radium -226 and radium -228 shall not exceed 5
pCi /L. In the event the result exceeds 5 pCi /L, the system shall begin quarterly
monitoring for both radium -226 and radium -228.
(e) Reduced monitoring. The Department shall allow community water
systems to reduce the future frequency of monitoring from once every three years to
once every six or nine years at each sampling point, based on the following criteria:
1. If the monitoring result for a contaminant (i.e., gross alpha particle activity,
uranium, radium -226, radium -228) is below the regulatory detection limit specified in
paragraph 62- 550.310(6)(c), F.A.C., above, the system shall collect and analyze for that
contaminant at that sampling point every nine years.
2. For gross alpha particle activity and uranium, if the monitoring result for
each contaminant is at or above the regulatory detection limit but at or below half the
MCL, the system shall collect and analyze for that contaminant using at least one
sample at that sampling point every six years. For radium -226 and radium -228, the
analytical results shall be combined. If the combined monitoring result for radium -226
and radium -228 is at or above 1 pCi /L, but at or below half the MCL (2.5 pCi /L), the
system shall collect and analyze for those contaminants at that sampling point every six
years.
3. For gross alpha particle activity and uranium, if the monitoring result for
each contaminant is above half the MCL but at or below the MCL, the system shall
remain on routine monitoring and shall collect and analyze at least one sample at that
sampling point every three years. If the combined monitoring result for radium -226 and
radium -228 is above half the MCL but at or below the MCL, the system shall remain on
routine monitoring and shall collect and analyze at least one sample at that sampling
point every three years.
4. Systems will multiple entry points to the distribution system could have
different monitoring schedules for radionuclides at each entry point. In the event such a
situation occurs, the system shall be responsible for keeping track of its monitoring
schedule.
Effective 2 -16 -12
36
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
(f) Systems shall use the samples collected during the initial, routine or
reduced monitoring period to determine the monitoring frequency for subsequent
monitoring periods (e.g., if a system's sampling point is on a nine year monitoring
period, and the sample result is above half the MCL, then the next monitoring period for
that sampling point is three years).
(g) If a system has a monitoring result that exceeds the MCL, the system shall
collect and analyze quarterly samples at that sampling point until the system has results
from four consecutive quarters that are below the MCL, unless the system enters into
another schedule as part of a formal compliance agreement with the Department.
When the combined MCL for radium -226 and radium -228 exceeds the MCL of 5 pCi /L,
the system shall begin quarterly monitoring for both radium -226 and radium -228.
Substitution of a gross alpha particle activity result for radium -226 shall not be allowed
when the combined result exceeds the MCL.
(h) Compositing. To fulfill quarterly monitoring requirements for gross alpha
particle activity, radium -226, radium -228, or uranium, a system may composite up to
four consecutive quarterly samples from a single entry point if analysis is done within a
year of the first sample. The Department shall treat analytical results from the
composited sample as the average analytical result to determine compliance with the
MCLs and the future monitoring frequency. If the analytical result from the composited
sample is greater than half the MCL, the Department shall direct the system to take one
year of additional quarterly samples before allowing the system to sample under a
reduced monitoring schedule.
(i) A gross alpha particle activity measurement may be substituted for the
required radium -226 measurement provided that the measured gross alpha particle
activity does not exceed 5 pCi /L. A gross alpha activity measurement may be
substituted for the required uranium measurement provided that the measured gross
alpha particle activity does not exceed 15 pCi /L. When a system uses a gross alpha
particle activity measurement in lieu of a radium -226 and /or a uranium measurement,
the gross alpha particle activity analytical result shall be used to determine the future
monitoring frequency for radium -226 and /or uranium.
0) If any sample result is less than the regulatory detection limit, zero shall be
used. If the gross alpha particle activity result is less than the regulatory detection limit
and is used in lieu of actual measurements for either radium -226 or uranium, then half
the regulatory detection limit (1.5 pCi /L) shall be used.
(2) Monitoring and Compliance Requirements for Beta Particle and Photon
Radioactivity. To determine compliance with the maximum contaminant levels in
paragraph 62- 550.310(6)(b), F.A.C., for beta particle and photon radioactivity, a system
shall monitor at a frequency as follows:
(a) Community public water systems (both surface water and ground water)
notified in writing by the Department as being vulnerable to such contamination shall
sample for beta particle and photon radioactivity. Systems must collect quarterly
samples for beta emitters and annual samples for tritium and strontium -90 at each entry
point to the distribution system (hereafter called a sampling point), beginning within one
quarter after being notified by the Department. Systems already designated by the
Effective 2 -16 -12
37
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
Department must continue to sample until the Department reviews and either reaffirms
or removes the designation.
1. If the gross beta particle activity minus the naturally occurring potassium -
40 beta particle activity at a sampling point has a running annual average (computed
quarterly) less than or equal to 50 pCi /L (screening level), the Department shall reduce
the frequency of monitoring at that sampling point to once every 3 years. Systems shall
collect all samples required in paragraph (2)(a) above during the reduced monitoring
period.
2. For systems in the vicinity of a nuclear facility, the Department may allow
the community water system to use environmental surveillance data collected by the
nuclear facility in lieu of monitoring at the system's entry point(s), when the Department
determines that such data is applicable to a particular water system. In the event that
there is a release from a nuclear facility, systems that are using surveillance data shall
begin monitoring at the community water system's entry point(s) in accordance with
paragraph (2)(a) above.
(b) Community water systems (both surface and ground water) designated by
the Department as using waters contaminated by effluents from nuclear facilities shall
sample for beta particle and photon radioactivity. Systems shall collect quarterly
samples for.beta emitters and iodine -131 and annual samples for tritium and strontium -
90 at each entry point to the distribution system (hereafter call a sampling point),
beginning within one quarter after being notified by the Department. Systems already
designated by the Department as systems using waters contaminated by effluents from
nuclear facilities shall continue to sample until the Department reviews and either
reaffirms or removes the designation.
1. Quarterly monitoring for gross beta particle activity shall be based on the
analysis of monthly samples or the analysis of a composite of three samples. The
former is recommended.
2. For iodine -131, a composite of five consecutive daily samples shall be
analyzed once each quarter. As ordered by the Department, more frequent monitoring
shall be conducted when iodine -131 is identified in the finished water.
3. Annual monitoring for strontium -90 and tritium shall be conducted by
means of the analysis of a composite of four consecutive quarterly samples or analysis
of four quarterly samples. The latter procedure is recommended.
4. If the gross beta particle activity beta minus the naturally occurring
potassium -40 beta particle activity at a sampling point has a running annual average
(computed quarterly) less than or equal to 15 pCi /L (screening level), the Department
shall reduce the frequency of monitoring at that sampling point to every 3 years.
Systems shall collect all samples required in paragraph (2)(b) above during the reduced
monitoring period.
5. For systems in the vicinity of a nuclear facility, the Department may allow
the CWS to use environmental surveillance data collected by the nuclear facility in lieu
of monitoring at the system's entry point(s), when the Department determines that such
data is applicable to a particular water system. In the event that there is a release from
a nuclear facility, systems that are using surveillance data shall begin monitoring at the
entry point(s) in accordance with paragraph (2)(b) above.

(c) Community water systems designated by the Department to monitor for
beta particle and photon radioactivity can not apply to the Department for a waiver from
the monitoring frequencies specified in paragraph (2)(a) or (2)(b) above.
(d) Community water systems may analyze for naturally occurring potassium -
40 beta particle activity from the same or equivalent sample used for the gross beta
particle activity analysis. Systems are allowed to subtract the potassium -40 beta
particle activity value from the total gross beta particle activity value to determine if the
screening level is exceeded. The potassium -40 beta particle activity shall be calculated
by multiplying elemental potassium concentrations (in mg /L) by a factor of 0.82.
(e) If the gross beta particle activity minus the naturally occurring potassium -
40 beta particle activity exceeds the appropriate screening level, an analysis of the
sample shall be performed to identify the major radioactive constituents present in the
sample and the appropriate doses shall be calculated and summed to determine
compliance with subparagraphs 62- 550.310(6)(b)l. and 2., F.A.C. Doses shall also be
calculated and combined for measured levels of tritium and strontium to determine
compliance.
(f) Systems shall monitor monthly at the sampling point(s) that exceed the
maximum contaminant level in paragraph 62- 550.310(6)(b), F.A.C., beginning the
month after the exceedance occurs. Systems shall continue monthly monitoring until
the system has established, by a running average of 3 monthly samples, that the MCL
is being met. Systems that establish that the MCL is being met shall return to quarterly
monitoring until they meet the requirements set forth in paragraph (2)(a)1. or (2)(b)4.,
above.

AND REPORTING
These rules are intended to implement the Primary and Secondary Drinking Water
Regulations that require community water systems to prepare and provide to their
customers annual consumer confidence reports (CCRs) on the quality of the water
delivered by the systems. In addition to the requirements of this rule, the requirements
contained in the following regulations are adopted and incorporated herein by reference
and are enforceable under this rule: the July 1, 2002, edition of 40 CFR 141, Subpart O,
sections 151 through 155, and Appendix A to 40 CFR 141, Subpart O; revisions to
Subpart O on pages 70855 through 70857 of the November 27, 2002, Federal Register,
and revisions to Subpart O on pages 73011 -74047 of the December 9, 2002, Federal
Register. Additional information may be obtained from the USEPA's guidance manuals
Preparing Your Drinking Water Consumer Confidence Report — Revised Guidance for
Water Suppliers, EPA 816 -R -01 -003, January 2001, and Revised State Implementation
Guidance for the Consumer Confidence Report (CCR) Rule, Appendix F, EPA 816 -R-
01 -002, January 2001, which are incorporated herein by reference.
(1) Additional Report Content Requirements. In addition to the requirements
of 40 CFR 141.153, the following requirements shall apply:
(a) Additional Source Water Information. If the Department has determined
that a system or well is under the direct influence of surface water, the system shall
identify the well and proposed remedial action.
(b) Water Treatment Information. Systems shall include a general description
of all major water treatment processes. For example, a statement may be worded in the
following way: Our water is obtained from ground water sources and is chlorinated for
disinfection purposes, and then fluoridated for dental health purposes.
(c) Additional Primary Contaminant Information.
1. In addition to the contaminants referenced in 40 CFR 141.153(d)(1)(i), the
following contaminants shall be subject to the requirements of §141.153(d): nickel, lead
(point of entry) and sodium. The applicable results for these three contaminants shall be
only the results of monitoring to demonstrate compliance with a maximum contaminant
level (MCL) in subsection 62- 550.310(1), F.A.C.
2. More Stringent MCLs. For the following contaminants, the Florida MCL is
more stringent than the federal MCL referenced in 40 CFR 141, Subpart O, Consumer
Confidence Reports: benzene, vinyl chloride, ethylene dibromide, carbon tetrachloride,
1,2- dichloroethane, trichloroethylene, and tetrachloroethylene. For these contaminants,
the Florida MCLs listed in Rules 62- 550.310 and 62- 550.320, F.A.C., shall apply for the
purpose of preparing the consumer confidence report.
3. Different Monitoring Location Requirements. Subsection 62- 550.500(5),
F.A.C., requires monitoring at the entry point to the distribution system rather than at
points within the distribution system, when monitoring for compliance with the MCLs for
the radiological contaminants listed in subsection 62- 550.310(6), F.A.C. These results
shall be applicable to the consumer confidence reports requirements of 40 CFR
141.153(d)(1)(i).
4. Primary Contaminant Source of Contamination Language. In addition to
the language found in 40 CFR 141, Appendix A to Subpart O, the following language
shall be used in tables of analytical results to report on the source of contamination for
lead (point of entry), nickel and sodium. Systems may substitute other language or add
Effective 2 -16 -12
68
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
their own language if the language they use as source of contamination language is
more specific to conditions affecting their system.
a. Lead (point of entry): Residue from man -made pollution such as auto
emissions and paint. Lead pipe, casing, and solder.
b. Nickel: Pollution from mining and refining operations. Natural occurrence
in soil.
C. Sodium: Salt water intrusion, leaching from soil.
5. Health Effects Language in Addition to that found in 40 CFR 141,
Appendix C to Subpart O. The following health effects language shall be used for nickel,
sodium, and lead (point of entry) when their MCLs have been exceeded:
a. Nickel: - Nickel has been shown to damage the heart and liver in
laboratory animals when the animals are exposed to high levels over their lifetimes.
The Florida Department of Environmental Protection (DEP) has set the drinking water
standard for nickel at 100 parts per billion (ppb) to protect against the risk of these
adverse effects.
b. Sodium: The Florida Department of Environmental Protection (DEP) has
set the drinking water standard for sodium at 160 parts per million (ppm) to protect
individuals that are susceptible to sodium - sensitive hypertension or diseases that cause
difficulty in regulating body fluid volume. Sodium is monitored so that individuals who
have been placed on sodium (salt) restricted diets may take into account the sodium in
their drinking water. Drinking water contributes only a small faction (less that 10
percent) to the overall sodium intake. Sodium levels in drinking water can be increased
by ion - exchange softeners at water treatment facilities or certain point -of -use treatment
devices. If you have been placed on a sodium restricted diet, please inform your
physician that our water contains <<insert sodim concentration>> ppm of sodium.
C. Lead (point of entry): Infants and children who drink water containing lead
in excess of the MCL could experience delays in their physical or mental development.
Children could show slight deficits in attention span and learning abilities. Adults who
drink this water over many years could develop kidney problems or high blood pressure.
6. Reporting total coliform results. When reporting the total monthly number
of samples include repeat samples.
7. Reporting fecal coliform results. If fecal coliform is detected, the table of
analytical results shall include the total number of positive samples for the year.
& Reporting nitrates and nitrites results. Analytical results for nitrates and
nitrites shall be reported individually. The reporting of analytical results of total nitrates
and nitrites is not required.
(d) Secondary Contaminant Information.
1. The reporting requirements of 40 CFR 141.153(d) shall be applicable to
the secondary contaminants listed in Rule 62- 550.320, F.A.C.
2. Reporting of secondary contaminants results.
a. Results subject to CCR reporting for secondary contaminants shall be the
most recent year's worth of results obtained during or before the calendar year previous
to the year the CCR is due, except that data older than five years need not be included.
Results shall be included in the table of secondary contaminants analytical results only if
the highest single sample result exceeds the MCL. On the table of secondary
Effective 2 -16 -12
69
DEP 2012 DRINKING WATER STANDARDS, MONITORING 62 -550
AND REPORTING
contaminants analytical results, the highest result shall be reported as the level
detected, and the range of results shall be reported as the range.
b. Results for pH need not be reported.
C. Results for ethylbenzene(odor), toluene(odor), and xylenes (odor), need
not be reported, because they are also monitored as primary contaminants.
3. Source of Secondary Contaminants. The following language is provided
for use in tables of results to describe the major sources in drinking water for the
secondary contaminants listed as follows. Systems may substitute other language or
add their own language if the language they use as source of contamination language in
the consumer confidence report is more specific to conditions affecting their system.
a. Color and odor: Naturally occurring organics.
b. Copper: Corrosion byproduct and natural occurrence from soil leaching.
C. Foaming agents: Pollution from soaps and detergents.
d. Flouride: Erosion of natural deposits; Water additive which promotes
strong teeth; Discharge from fertilizer and aluminum factories.
e. All other secondary contaminants: Natural occurrence from soil leaching.
(e) Unregulated Contaminants. Systems required to monitor for unregulated
contaminants by 40 CFR 141.40 shall report analytical results when there are
detections of unregulated contaminants. If unregulated contaminants are detected the
CCR shall include the following informational statement: <<Insert name of system>>
has been monitoring for unregulated contaminants (UCs) as part of a study to help the
U.S. Environmental Protection Agency (EPA) determine the occurrence in drinking
water of UCs and whether or not these contaminants need to be regulated. At present,
no health standards (for example, maximum contaminant levels) have been established
for UCs. However, we are required to publish the analytical results of our UC
monitoring in our annual water quality report. If you would like more information on the
EPA's Unregulated Contaminants Monitoring Rule, please call the Safe Drinking Water
Hotline at (800) 426 -4791.
(f) Information Collection Rule (ICR) Contaminants. The federal CCR
regulations (40 CFR 141.153) state that finished water results for the following are
subject to consumer confidence reporting requirements: disinfection by- products or
microbial contaminants for which monitoring is required under 40 CFR 141.142 and
141.143 except Cryptosporidium.
1. Systems monitoring for ICR contaminants shall report the following ICR
contaminants in their consumer confidence reports, if found in the finished water:
a. THM4: trihalomethanes (chloroform, bromodichloromethane,
dibromochloromethane, and bromoform) - report as a group,
b. HAAS: haloacetic acids (mono -, di -, and trichloroacetic acid, and mono -
and di- bromoacetic acid) — report as a group,
C. HAN: haloacetilenitriles (dichloro -, tichloro-, bromochloro -, and
