62-550.102 Intent and Scope. (1) To assure that public water systems supply drinking water which meets minimum requirements, the Federal Governm ent 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 "Flo rida 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 Governm ent where possible, and otherwise create

additional rules to fulfill stat e and Federal requirements. (2) The Safe Drinking Water Act and the Florida Safe Drinking Water Act exclude certain public water systems from co verage. 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 l and 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 facilitie s” shall exclude treatment fac ilities 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 constructi on of wells serving the system and the treatment plant. Construction of public wa ter systems require permits and the use of lead free pipes, plumbing fixtures, solder and flux. General permits for public water systems are included. Engineeri ng references are listed. (6) Chapter 62-560, F.A.C., gives the descr iption of the violations of Chapters 62-550, 62-555, and 62-560, F.A.C ., and the resulting penalties. In addition, this chapter describes public notification requirements for public water systems that do not meet2 applicable maximum contaminant levels, maximu m residual disinfectant levels, and treat technique requirements; do not meet applicabl e 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 contami nants and disinfectant residuals. Specific Authority 403.861(9), FS. Law Im plemented 403.851, 403.853, FS. History -- New 11-9-77, Amended 1-13-81, Formerly 17-22.102, Amended 1-18-89, Formerly 17- 550.102, Amended 12-9-96, 11-27- 01, 4-3-03, 11-28-04.

NOTE: Section 381.261, F.S., gives general supervision and control over all private water systems and public water systems not cove red 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 contro l 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.

QUALITY STANDARDS

62-550.300 Application of Quality Sta ndards to Public Water Systems. The ultimate concern of the public water syst em 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 s hall comply with the MCLs, MRDLs, and treatment technique requirements estab lished 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 MC Ls, MRDLs, and treatment technique requirements. Specific Authority 403.861(9), FS.

Levels and Maximum Residua l 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 nitrat e 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 her ein 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 notificati on of what the nitrate level (as N) is and the potential health effects of such exposure are. 3. The Department shall require moni toring every 3 months as long as the

maximum contaminant level is exceeded. Should adverse health effects occur, the Department shall require immediate compli ance 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 nontransient non-community water systems adding a c hemical disinfectant to the water in any part of the drinking water treatment proce ss. 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-communi ty 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 disi nfection byproducts are listed in Table 3, which is incorporated herein and appear s at the end of this chapter. (4) ORGANICS – This subsection applies only to community water systems and non-transient non-community water systems. (a) The maximum contaminant levels for the volatile organic contaminants (VOCs) are listed in Table 4, which is in corporated 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 leve ls and the regulatory detection limits (RDLS) for the synthetic organi c 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 comp liance with this subsection are defined in Rule 62-550.518, F.A.C.12 (a) The maximum contaminant level is based on the presence or absence of total coliforms in a sample, rather than co liform 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 l east 40 samples per month, if no more than 5.0 percent of the samples collected duri ng 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 to tal coliform-positive, the system is in compliance with the maximum contaminant level for total coliforms. (b) Any fecal coliform-positive repeat sample or E.coli -positive repeat sample, or any total coliform-positive repeat samp le 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 requirement s 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-comm unity water systems that use only ground

water not under the direct influence of su rface 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 unl ess other monitoring or compliance measurement requirements ar e 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 monito ring framework developed to address the issues of complexity, coordination between va rious rules, and coordination of monitoring schedules. A compliance cycle is a nine-year period during which all public water systems must monitor. Compliance cycl es begin January 1, 2002, and January 1,17 2011, and every nine years thereafter. Each compliance cycle is broken down into three three-year compliance periods. For ex ample, 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 ar e 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 wa ter 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 cont aminant quarterly may do so any time during the quarter, except that samples tak en 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. (c) Systems that monitor for a contam inant 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 contam inant every six years shall monitor as directed by the Department. (e) Systems that monitor for a cont aminant 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 sha ll 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 noncommunity systems shall be approved to moni tor earlier during compliance periods or cycles than required by paragraphs (c) through (e) above. (4) Increased Monitoring. When specif ied by the State Health Officer, the Department shall require more frequent moni toring 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 distri bution system that is representative of each source after treatment (hereafter called a sa mpling point). The system shall take each sample at the same sampling point unle ss 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 direct18 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 mu st sample at an entry point to the distribution system during periods of typica l operating conditions (e.g., when water is representative of the sources being used). (6) Confirmation Samples. The syst em shall take confirmation samples whenever a sample exceeds the maximum cont aminant level for nitrate or nitrite and whenever an unregulated contaminant is detec ted. However, a system may take confirmation samples for other inorgani c contaminants, or ganic contaminants, radionuclides, or secondary contaminants. Fo r regulated contaminants, the results of confirmation samples shall be averaged with t he first sampling results and the average 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, a fter 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 syst em 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 sha ll 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, tak en within a quarter and analyzed under the provisions of this section (even if that num ber is greater than the minimum required), to obtain an average for the quarter to det ermine compliance with these rules. (b) A system monitoring annually or less frequently for the inorganic contaminants, other than nitrat e or nitrite, listed in subs ection 62-550.310(1), F.A.C., the volatile organic contaminants listed in par agraph 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 subsec tion 62-550.310(6), F.A.C., whose sample result exceeds

the maximum contaminant level will not be c onsidered in violation of the maximum contaminant level until it has completed one y ear of quarterly sampling. If the running annual average of any sampling point is great er 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 ex ceed the maximum contaminant level, then the system is immediately out of compli ance. 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 bel ow the regulatory detection limit shall be calculated as zero for purposes of determi ning 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 consi dered acute contaminants. (c) The Department shall delete results of obvious sampling or analytic errors.19 (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, ni trate, 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. System s 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. A ll new systems or systems that use a new source of water shall demonstrate complianc e with all maximum contaminant levels. The system shall comply with the initial sampling frequencies as specified in this chapter. Routine and increased monito ring frequencies shall be conducted in accordance with the requirements in this chapter. Specific Authority 403.861(9), FS.

(c) Systems which serve less than or equal to 3,300 persons that do not

detect a contaminant in the initial co mpliance period may reduce the sampling frequency to one sample during each repeat compliance period. (d) Systems may apply to the Department for a monitoring waiver as specified in Rule 62-560.545, F.A.C. (2) Sampling location. During the first quarter of the initial base point monitoring, ground water systems shall take a minimum of one sample that is representative of each well. The sample may be collected as a raw or treated sample. Subsequent samples shall be taken as directed by subsection 62-550.500(5),

F.A.C. (3) Systems monitoring annually or less frequently whose sample result exceeds the regulatory detection level sha ll begin quarterly sampling. Detection as used in this rule shall be defined as a sample result greater than the concentration for

each contaminant as listed in the column headed “Regulatory Detection Limit” in Table 5, which appears at the end of this chapter. (4) Monitoring Requirements After a C ontaminant Is Detected. If an organic contaminant listed in paragr aph 62-550.310(4)(b), F.A.C., is detected in any sample: (a) The system shall notify the Departm ent within seven days after receiving the laboratory results and shall monitor quarterly at each sampling point where a

62-550.517 Physical Characteris tics Monitoring Requirements.(1) All community, non-transient non-community, and transient noncommunity public water systems that use any surface water sources, or ground water

sources under the direct influence of surface wa ter, shall monitor for turbidity pursuant to Rule 62-550.560, F.A.C. (2) All public water systems using ground water not under the direct influence of surface water are required by subsecti ons 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 anal ysis 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 dire ct influence of surface water. If the Department renders a written decision that t he source is not under the direct influence of surface water, or if no subsequent raw wa ter samples are positive for bacteria during the following one-year period, m onitoring 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 wa ter, the system shall comply with Rule 62- 550.817, F.A.C. In the event the system not ifies the Department in writing that it disagrees with the Department's determinati on, 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 M onitoring 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 ar e representative of water throughout the distribution system and in accordance with a written sampling plan that addresses location, timing, frequency, and rotation peri od. These plans shall be available for review and possible revision on the occasion of a sanitary survey conducted by the Department. Descriptions of sampling locati ons shall be specific, i.e., numbered street25 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 t he system. Community water systems, nontransient non-community water systems, tr ansient non-community water systems that are subpart H systems and transient non-comm unity water systems that serve more than 1,000 persons per day during any one mont h shall take monthly distribution system samples. In addition, systems that ar e using ground water not under the direct

influence of surface water shall take a minimu m 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.

under the direct influence of surface wate r and serving 1,000 or fewer persons shall monitor at the rate of two distribution syst em 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 t hat 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 in stalled 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 analyz ed 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 followi ng 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 wr iting by the Department to do so. (b) If a routine distribution system sample is total-coliform-positive, the public water system shall 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 than three repeat samples for each total-colifo rm-positive sample found. A transient noncommunity water system that collects quarterl y 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 contro l in collecting the repeat samples within 24 hours. If an extension is granted, the Depar tment 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 subsec tion 62-550.518(8), F.A.C.28 (c) The system shall collect at leas t one repeat distribution system sample from the sampling tap where the original to tal-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 t he beginning or end of the distribution system, or one service connection away from the beginni ng or end of the distribution system, the system need not collect a repeat sample ups tream or downstream of the original sampling site, whichever is applicable, but st ill 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 addi tional 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 colifo rms in subsection 62-550.310(5), F.A.C., has been exceeded and notifies the Department in a ccordance with subsections (10) and (11) below. (e) Results of all routine and r epeat distribution system samples not invalidated by the Department shall be in cluded in determining compliance with the

maximum contaminant level for total colif orms in subsection 62-550.310(5), F.A.C. (8) If a system collecting fewer than fi ve 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 sample s during the next month the system provides water to the public. (9) Invalidation of Total Coliform Samp les. A total-coliform-positive sample invalidated under this subsection does not count toward meeting the minimum monitoring requirements of this section. Department invalidation of a total-coliformpositive sample invalidates subsequent fecal-coliform or E.-coli -positive results on the same sample. (a) The Department shall invalidate a to tal-coliform-positive sample only if any 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 t he results of the repeat distribution system samples collected as required by subsec tion (7) of this section, determines that the total-coliform-positive sample result ed from a non-distribution system plumbing 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 shall not invalidate a total-coliform-positive sample on the basis of repeat samples if all the repeat samples are total-coliform-negative or if the public water system has only one

service connection. 3. The Department has received in wr iting 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, the29 system shall still collect all repeat di stribution 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 c ause 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-colif orm-positive sample solely on the grounds that all repeat samples ar e 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 forma tion is examined (e.g., the Multiple-Tube Fermentation Technique); produces a turbid cu lture 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 analyt ical method using a membrane filter (e.g., Membrane Filter Technique). If a laborator y 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 samp le from the same location as the original sample within 24 hours of being not ified 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 Departm ent shall expand the 24-hour requirement on a case-by-case basis if the system has a logist ical problem that is beyond its control in collecting the repeat samples within 24 hour s. 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 anal yze 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 cons idered to be meeting the bacteriological requirements in subsection 62-555.315(6), F.A.C., the system shall notify the appropriate Department of Envi ronmental Protection (DEP) Dis trict Office or appropriate Approved County Health Department (ACHD) by the end of the day that the system learns of the test result unless the system l earns 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 appropr iate 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 spec ified 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 violati on 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 t han 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.30 (b) A public water system that has failed to comply with a coliform monitoring requirement shall report the monitoring violat ion to the Department within 48 hours after the system discovers the violation, and sha ll notify the public in accordance with Rule 62-560.410, F.A.C.

62-550.519 Radionuclides Moni toring 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 in itial 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 resu lt is the number that the laboratory reports, not including (i.e., not adding or s ubtracting) 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 consec utive quarterly samples at all sampling points. Systems serving more than 3,300 people shall begin sampling January 1, 2005. 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 fi nal 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 monito ring results for any sampling point is above the MCL, the system is out of complianc e. 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 co mpliance 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 cont aminant 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 t he regulatory detection limit but at or below half the MCL, systems serving more than 3, 300 people sha ll sample again for that contaminant during 2011. Systems serving 3,300 or fe wer people shall sample again during 2012.31 6. Systems serving more than 3,300 people that are required to sample during the initial monitoring period and hav e 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 per iod 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 gr oss 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. R outine monitoring will take place every three years and must meet the following conditions: 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 ex ceed 15 pCi/L. The system may either sample for uranium or may substitute the gro ss 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 t he gross alpha result in order to determine compliance with the gross alpha MCL. In t he 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 exc eed 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 t he 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 m onitoring from once every three years to once every six or nine years at each samp ling point, based on the following criteria: 1. If the monitoring result for a contam inant (i.e., gross alpha particle activity, uranium, radium-226, radium-228) is below the regulatory detection limit specified in32 paragraph 62-550.310(6)(c), F.A.C ., above, the system shall collect and analyze for that contaminant at that sampli ng point every nine years. 2. For gross alpha particle activity and uranium, if the monitoring result for

each contaminant is at or abov e the regulatory detection limit but at or below half the MCL, the system shall collect and analyze fo r 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 cont aminants 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 bel ow 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 respons ible for keeping track of its monitoring

schedule. (f) Systems shall use the samples co llected during the init ial, routine or reduced monitoring period to determine the monitoring frequency for subsequent monitoring periods (e.g., if a system’s sa mpling point is on a nine year monitoring period, and the sample result is above half t he 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 bel ow the MCL, unless the system enters into another schedule as part of a formal comp liance agreement with the Department.

When the combined MCL for radium-226 and r adium-228 exceeds the MCL of 5 pCi/L, the system shall begin quarterly monitori ng 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 quarterl y 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 si ngle 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 D epartment shall direct the system to take one year of additional quarterly samples befor e 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 measurem ent provided that the meas ured gross alpha particle activity does not exceed 5 pCi/L. A gross alpha activity measurement may be substituted for the required uranium measur ement provided that the measured gross alpha particle activity does not exceed 15 p Ci/L. When a system uses a gross alpha particle activity measurement in lieu of a radium-226 and/or a uranium measurement,33 the gross alpha particle activity analytical re sult shall be used to determine the future monitoring frequency for radium-226 and/or uranium. (j) If any sample result is less than t he regulatory detection limit, zero shall be used. If the gross alpha particle activity resu lt is less than the regul atory 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 wit h 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 bei ng vulnerable to such contamination shall sample for beta particle and photon radioacti vity. Systems must collect quarterly samples for beta emitters and annual samples fo r 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 Departm ent. Systems already designated by the Department must continue to sample until t he Department reviews and either reaffirms or removes the designation. 1. If the gross beta particle activity minus the naturally occurring potassium40 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 poi nt 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 nuc lear facility, the Department may allow the community water system to use environm ental 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 syst em’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 radioacti vity. Systems shall collect quarterlysamples for beta emitters and iodine-131 and annual samples for tritium and strontium90 at each entry point to the distributi on system (hereafter call a sampling point), beginning within one quarter after being notified by the Department. Systems already designated by the Department as systems usi ng 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 i dentified in the finished water. 3. Annual monitoring for strontium- 90 and tritium shall be conducted by means of the analysis of a composite of f our consecutive quarterly samples or analysis of four quarterly samples. The latter procedure is recommended.34 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 t hat sampling point to every 3 years. Systems shall collect all samples requir ed in paragraph (2)(b) above during the reduced monitoring period. 5. For systems in the vicinity of a nuc lear facility, the Department may allow

the CWS to use environmental surveillance dat a 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 su rveillance 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 appl y 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 potassium40 beta particle activity from the same or equivalent sample used for the gross beta particle activity analysis. Systems are a llowed to subtract the potassium-40 beta particle activity value from the total gross bet a particle activity value to determine if the screening level is exceeded. The potassium-40 bet a particle activity shall be calculated by multiplying elemental potassium concent rations (in mg/L) by a factor of 0.82. (e) If the gross beta particle activity minus the naturally occurring potassium40 beta particle activity exceeds the appr opriate screening level, an analysis of the sample shall be performed to identify the majo r 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)1. 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. System s shall continue monthly monitoring until the system has established, by a running aver age of 3 monthly samples, that the MCL is being met. Systems that establish that t he MCL is being met shall return to quarterly monitoring until they meet t he requirements set forth in paragraph (2)(a)1. or (2)(b)4.,

62-550.817 Additional Requirements fo r Subpart H Water Systems. The requirements for subpart H systems in th is section apply to all subpart H systems except where noted in this section and are in addition to the requirements applicable to all public water systems found elsewhere in Chapters 62-550, 62-555, and 62-560. Subparagraph 62-550.817(1)(b)2., and par agraphs 62-550.817(10)(e) and 62- 550.817(12)(b), F.A.C., apply only to consec utive systems that receive any finished water originating from a subpart H system. In addition to the requirements of this section, the standards and crit eria contained in the regulations adopted in subsections 62-550.817(1), (2), and (3), F.A.C., are adopted by reference and enforceable under these rules. A subpart H system is c onsidered to be in compliance with the requirements of this section if it meets all the requirements set forth in this section. A subpart H system is considered to be out of compliance with the requirements of this section if it does not meet all the requi rements set forth in this section. (1) Scope of Requirements. (a) These rules are intended to impl ement the National Primary Drinking Water Regulations related to the disinfecti on and filtration of surface water and ground

water under the direct influence of surface wa ter, and the recycle of fluids referenced in 40 CFR 141.76(a) (2002) by subpart H systems t hat employ conventional filtration or

direct filtration treatment. 1. They adopt filtration and disinfec tion as best available treatment techniques for the removal or inactivation of pathogens in lieu of establishing a45 maximum contaminant level for the following contaminants: C ryptosporidium, Giardia

lamblia , viruses, heterotrophic plate count (HPC) bacteria, Legionella , and turbidity. Subpart H systems shall provide tr eatment of those part(s) of their source water that are surface water or ground water under the dire ct influence of surface water. Such treatment shall comply with the treatm ent technique requirements found in paragraph 62-550.817(2)(b), F.A.C., in lieu of maximum contaminant levels for Cryptosporidium

, Giardia lamblia , viruses, HPC bacteria, Legionella, and turbidity. 2. Recycle provisions. In addition to t he requirements of this chapter, the

standards and criteria contained in the Ju ly 1, 2002, edition of 40 CFR 141.76 are adopted by reference and enforceable under this rule. (b) For purposes of the requirements of this section: 1. The number of persons served by a wholesale system includes the number of persons served by the consecutiv e systems that receive finished water from the wholesale system; and 2. Consecutive systems that receive any finished water originating from a subpart H system are considered subpart H syst ems for the purpose of demonstrating compliance with the distribution system disi nfection residual maintenance requirements of 40 CFR 141.72(b)(3)(i), adopted in subsec tion 62-550.817(2), F.A.C., the monitoring requirements of paragraph 62-550.817(10)(e), and the reporting requirements of paragraph 62-550.817(12)(b), F.A.C. 3. When using Form 62-555.900(2), F.A. C., (the Monthly Operation Report or MOR form) to calculate CT and other va lues, input data and output data must be within the ranges provided in the MOR form in order to be valid. 4. To determine compliance with the following standards for removal or inactivation, actual log-inactivation due to disinfectants shall be rounded to the same number of significant figures as the standards: 2.0 log Cryptosporidium , 3.0 log Giardia

lamblia , and 4.0 log viruses. (2) Filtration and Disinfection. In additi on to the requirements of this chapter,

the standards and criteria contained in the July 1, 2002, edition of 40 CFR 141.13, 141.22, 141.70(a), (b)(2), (c), (d), (e), 141.71( b)(6), 141.72, 141.72(a), 141.72(b)(1), (2), (3)(i), 141.73, 141.74, 141.75 are adopted by re ference and enforceable under this rule. However, 40 CFR 141.72(b)(3)(ii) is not adopted. (a) The following are clarifications and additions to the regulations adopted in subsection 62-550.817(2), F.A.C. 1. The method used to determine which ground water systems are under the direct influence of surface water (UDI ) is described in chapter 2 of the Guidance Manual for Compliance With the Filtration and Disin fection Requirements for Public Water Systems Using Surface Water Sources , adopted in subsection 62-555.335(1), F.A.C., and implemented in subsec tion 62-550.517(2), F.A.C.

2. No later than 18 months after the Department has determined that a ground water system is under the influence of surface water as described in subsection 62-550.517(2), F.A.C., the system shall comply with the filtration requirements of 40

CFR 141.73. No later than 6 months after the Department determination pursuant to subparagraph 1. above, the system shall comply with the interim disinfection treatment technique described in a., b., and c. below. “Interim” refers to the period between Department determination that the system is UDI and the st art of compliance with the filtration requirements of 40 CFR 141.73.

a. Interim disinfection treatment r equirements shall be in accordance with 40 CFR 141.72(a).46 b. Interim monitoring requirements shall be in accordance with 40 CFR 141.74(b). c. Interim reporting requirements shall be in accordance with 40 CFR 141.75(a). 3. Starting no later than the end of t he interim period and continuing as long as the systems remain subpart H systems, subpart H systems shall provide treatment consisting of both disinfection and filtra tion treatment which complies with the requirements of 40 CFR 141.72(b) and 141.73, respectively. (b) Treatment Techniques. 1. The treatment technique requirem ents consist of installing and properly operating filtration and disinfection water treat ment processes that reliably achieve: a. At least 99.9 percent (3-log) removal or inactivation of Giardia lamblia

between a point where the raw water is not subjec t to recontamination by surface water runoff and a point downstream, before or at taps providing water for human consumption; and b. At least 99.99 percent (4-log) remova l or inactivation of viruses between a point where the raw water is not subject to recontamination by surface water runoff or, after December 31, 2005, exposed during treatment to the open atmosphere and a point downstream, before or at taps provid ing water for human consumption. For the purposes of subsection 62-550.817(2), aerators and other facilities that are protected against contamination from birds, insect s, wind borne debris, rainfall, and drainage are not considered to be exposing water to the open atmosphere and possible viral

contamination. 2. Log-removal credit through filtration. The Department shall determine if a system is well-operated based on monthly operation report records, sanitary survey and compliance inspection results, CPE results, and any other relevant information. Welloperated filtration treatment plants are given the following log-removal credit:

62-550.824 Consumer Confidence Reports

. These rules are intended to implement the Primary and Secondary Drinking Water Regulations that require community wate r systems to prepare and provide to their customers annual consumer confidence repor ts (CCRs) on the quality of the water delivered by the systems. In addition to the r equirements 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-R01-002, January 2001, which are inco rporated herein by reference. (1) Additional Report Content Requirem ents. In addition to the requirements of 40 CFR 141.153, the followi ng requirements shall apply: (a) Additional Source Water Informa tion. If the Department has determined that a system or well is under the direct in fluence of surface water, the system shall identify the well and proposed remedial action. (b) Water Treatment Information. S ystems shall include a general description of all major water treatment processes. Fo r 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 re ferenced in 40 CFR 141.153(d)(1)(i), the following contaminants shall be subject to t he requirements of §141.153(d): nickel, lead (point of entry) and sodium. The applicable resu lts for these three contaminants shall be only the results of monitoring to demonstr ate compliance with a maximum contaminant level (MCL) in subsection 62-550.310(1), F.A.C. 2. More Stringent MCLs. For the follo wing contaminants, the Florida MCL is more stringent than the federal MCL refe renced in 40 CFR 141, Subpart O, Consumer Confidence Reports: benzene, vinyl chloride, et hylene dibromide, carbon tetrachloride, 1,2-dichloroethane, trichloroet hylene, 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 cons umer confidence report. 3. Different Monitoring Location Requi rements. 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 m onitoring for compliance with the MCLs for61 the radiological contaminants listed in s ubsection 62-550.310(6), F.A.C. These results shall be applicable to the consumer conf idence 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. S ystems may substitute other language or add 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 expos ed to high levels over their lifetimes. The Florida Department of Environmental Pr otection (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-sens itive hypertension or diseases that cause difficulty in regulating body fluid volume. S odium is monitored so that individuals who have been placed on sodium (salt) restricted diet s may take into account the sodium in their drinking water. Drinking water cont ributes only a small faction (less that 10 percent) to the overall sodium intake. Sodi um levels in drinking water can be increased by ion-exchange softeners at water treatment fa cilities or certain poi nt-of-use treatment devices. If you have been placed on a sodium restricted diet, please inform your physician that our water contains <<inser t 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 att ention span and learning abilities. Adults who drink this water over many years could dev elop 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 fe cal coliform is detected, the table of analytical results shall include the total num ber of positive samples for the year. 8. Reporting nitrates and nitrites results. Analytical results for nitrates and nitrites shall be reported individually. The repor ting 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 list ed 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 dat a older than five years need not be included.62 Results shall be included in the table of sec ondary contaminants analytical results only if the highest single sample result exceeds the MCL. On the table of secondary contaminants analytical results, the highes t 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 Contami nants. 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. S ystems 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 spec ific to conditions affecting their system. a. Color and odor: Naturally occurring organics. b. Copper: Corrosion byproduct and natur al 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 fert ilizer and aluminum factories. e. All other secondary contaminants: Natural occurrence from soil leaching. (e) Unregulated Contaminants. System s required to monitor for unregulated contaminants by 40 CFR 141.40 shall repor t 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 cont aminants 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 Ru le, please call the Safe Drinking Water Hotline at (800) 426-4791. (f) Information Collection Rule (I CR) Contaminants. The federal CCR regulations (40 CFR 141.153) st ate that finished water results for the following are subject to consumer confidence reporting r equirements: disinfection by-products or

microbial contaminants for which monito ring is required under 40 CFR 141.142 and 141.143 except Cryptosporidium. 1. Systems monitoring for ICR cont aminants shall report the following ICR

contaminants in their consumer confidence reports, if found in the finished water: a. THM4: trihalomethanes (chl oroform, bromodichloromethane, dibromochloromethane, and brom oform) - report as a group, b. HAA5: haloacetic acids (mono-, di-, and trichloroacetic acid, and monoand di-bromoacetic acid) – report as a group, c. HAN: haloacetilenitriles (dichl oro-, trichloro-, bromochloro-, and dibromoacetonitrile) - report as a group, d. HK: haloketones (1,1-dichl oropropanone and 1,1,1-tr ichloropropanone) -

As required by the 40 CFR 141.153, results for the above contaminants, if found in the finished water, shall be report ed in the table of analytical results in consumer confidence reports in the same manner as the unregulated contaminants (average and range of detection.) (g) Additional health information requi red by 40 CFR 141.154. In addition to the requirements of 40 CFR 141.154, systems shall also include this additional health information when they:

1. Detect arsenic or nitrate at the MC L. Report the informational statements required by 40 CFR 141.154(b) or (c), respectively. 2. Detect TTHM at the MCL. Include in the report the informational statements required by 40 CFR 141.154(e). (h) Educational Statement for Lead. If lead is detected above the action level in more than five percent, and up to and including ten percent of homes sampled, the system shall include in its CCR the language se t forth in 40 CFR 141.154(d). Systems that collect fewer than 20 samples during eac h monitoring period do not have to include

the educational statement for lead. (i) Operation Violations. System s with any of the problems listed in subparagraphs 1 – 3 below shall provide an explanation of the violation in their consumer confidence reports. The expl anation shall include a description of the

MCLs for nickel and sodium listed in subsec tion 62-550.310(1), F.A.C., shall include in

their CCRs: 1. An explanation of the reasons for the variance or exemption;

2. The date on which the vari ance or exemption was issued; 3. A brief status report on the steps t he system is taking to install treatment, find alternative sources of water, or ot herwise comply with the terms and schedules of the variance or exemption; and 4. A notice of any opportunity for public input in the review or renewal of the variance or exemption.65 (2) Use of Language Other Than English. Under 40 CFR 141.153(h)(3), where the proportion of non-English speaki ng residents served by the system exceeds 20 percent of the total number of cons umers served by the system, consumer confidence reports shall contain: informa tion in the appropriate language(s) regarding the nature and importance of the report and a telephone number or address where such residents may contact the system to obtain a tr anslated copy of the report or assistance in understanding the report. A statement to this effect shall be included in the report immediately after the title of the report. (3) Report Delivery and Recordkeeping. These rules provide additional requirements to those in 40 CFR 141.155. (a) Existing systems shall deliver their second CCR reports by July 1, 2000, and subsequent reports by July 1 annually t hereafter. A new community water system activated after January 1, 1998, shall deliver its first report by July 1 of the year after its first full calendar year in operation and annually thereafter. (b) A community water system that se lls water to another community water system shall deliver the applicable informati on required in 40 CFR 141.153 to the buyer system by April 1, 2000, and by April 1 annually thereafter, or on a date mutually agreed upon by the seller system and the buyer system, and specifically included in a contract between the parties. (c) Distribution Via the Internet. In accordance with 40 CFR 141.155(f), each community water system serving 100,000 or mo re shall post its current year’s CCR on a publicly accessible Internet site annually beginning July 1 for a period of no less than one year, and shall provide the Department wit h information on the appropriate Internet link(s) to its CCR using Form 62-555.900(19), F.A.C. (d) Mailing Requirements. All systems s hall mail or otherwise directly deliver one copy of their consumer confidence repor t to each billing customer. A community water system that sells water to another community water system need not deliver or mail its CCR to the buyer system if it has furnished the required consumer confidence information to the buyer system in accor dance with paragraph 62-550.82 4(3)(b), F.A.C. Systems must make a good faith effort to reac h all consumers, using one or more of the methods listed in Form 62-555.900(19), Cert ification of Delivery of Consumer Confidence Report, hereby adopted and incorporated by reference, effective date April 10, 2003.

In accordanc e with 40 CFR 141.155(g), the State of Florida waives the requirement that co mmunity water systems serving fewer than 10,000 persons mail or directly deliver to each billing customer their consumer confidence reports provided that the syst ems have not had any MCL or monitoring and reporting (M/R) violations, nor have been iss ued formal Notices of Violations (NOVs), Consent Orders, Administrative Orders, or court-ordered civil actions during the year covered by the CCR. 2. The Department will notif y systems that are ineligible for a mailing waiver in writing no later than April 1 annually. a. Community water systems serving fewer than 10,000 persons that have been granted a mailing waiver shall publish their CCRs due July 1 of the current year in local newspapers, and shall do so at least onc e each year no later than July 1 of that

same year. b. In lieu of the requirement se t forth in sub-subparagraph a. above, community water systems serving 500 or fe wer persons that have been granted mailing66 waivers and that elect to post notice(s) t hat the CCR is not being sent out but is available upon request, may post their notices in publicly accessible areas such as community bulletin boards for a period of no less than 30 days beginning no later than July 1 of that same year annually. c. Prior to the CCR’s publication dat e(s) in a local newspaper, community water systems granted mailing waivers shall not ify customers of t he publication date(s), and shall inform customers that a copy of the CCR will not be mailed to them individually. (e) Reporting. 1. Systems shall demonstrate compli ance with the reporti ng requirements of 40 CFR 141.155(c) by a. Sending a copy of their consumer confidence report to the appropriate office of the Department no later than the dat e the system is required to distribute the report to its customers, and b.

Systems taking more thanone sample shall take at least 25% of thesamples at locations representing maximum residence time of the water in the distribution system and shall take theremaining samples at locations representing at least average residence time in thedistribution systemand representing the entire distribution system, taking intoaccount number of persons served,different sources of water,and different treatment methods.NOTE 5: Systems shall take routine dailysamples at the entrance to the distribution system. Systemsshall take routine monthlyor additional three-set samples inthe distribution system; each three-set sample shall consist of one sample at each ofthe following locations: a location as close to the first customer as possible, alocation representative of average residence time, and a location reflecting maximum residence time in the distribution system.NOTE 6: For initial base point monitoring,systems shall take four consecutive quarterly samples during the first three-year compliance period. If a system does notdetect any VOC, it shall take one sample annually beginning with the next three-year compliance period.NOTE 7: During the first quarter of initialbase point monitoring, GW systems shall takea minimum of one sample that is representative of each well. Under all othercircumstances, systems shall sample at every entry point tothe distribution system during normal operating conditions.NOTE 8: The minimum number of samples shall beas set forth in Rule 62-550.518(2), F.A.C.NOTE 9: Systems shall conduct repeat monitoring in accordance with Rule 62-550.518(7),F.A.C., and systems that routinely collect fewer than five samples per monthshall collect at least five samples during the next month the system provides water to the public.NOTE 10: The Department shall waive the finaltwo quarters of initial monitoring for asampling point if the results of the samples from the previous two quarters arebelow the regulatory detection limit. Additionally, under the conditions described inRule 62-550.519(1)(c), F.A.C., historical data may be used to satisfy initial monitoringrequirements.NOTE 11: Quarterly monitoring for gross betashall be based on the analysis of monthly samples or the analysis of a composite of three monthly samples. For iodine131, a composite of five consecutive daily samples shall be analyzed once eachquarter. Annual monitoring for tritium and strontium-90 shall be conducted by means ofthe analysis of a compositeof four consecutive quarterly samplesor analysis of four quarterly samples.DEP 2007 DRINKING WATER STANDARDS, MONITORING 62-550AND REPORTINGEffective 9-18-0781TABLE 8: INITIAL OR ROUTINE MONITORING SCHEDULEREFERENCE RULE 62-550.500(3)Under initial or routine monitoring, public water systems shall take required samples during the time period specified below.CONTAMINANT OR DISINFECTANTRESIDUAL GROUPCOMMUNITY WATER SYSTEMSSERVING MORE THAN 3,300 PEOPLECOMMUNITY WATER SYSTEMSSERVING 3,300 OR FEWER PEOPLENON-TRANSIENT NON-COMMUNITYWATER SYSTEMSTRANSIENT NON-COMMUNITYWATER SYSTEMSASBESTOSRULES 62-550.500(3) & 62-550.511FIRST YEAR OF EACH NINE-YEARCOMPLIANCE CYCLESECOND YEAR OF EACH NINE-YEARCOMPLIANCE CYCLETHIRD YEAR OF EACH NINE-YEARCOMPLIANCE CYCLENOT REQUIREDNITRATES AND NITRITESRULES 62-550.500(3)& 62-550.512GROUNDWATERSYSTEMSANNUALLYSUBPART HSYSTEMSQUARTERLYANNUALLYINORGANICSRULES 62-550.500(3)& 62-550.513GROUNDWATERSYSTEMSFIRST YEAR OF EACH THREE-YEARCOMPLIANCE PERIODSECOND YEAR OF EACH THREEYEAR COMPLIANCE PERIODTHIRD YEAR OF EACH THREE-YEARCOMPLIANCE PERIODNOT REQUIREDSUBPART HSYSTEMSANNUALLYNOT REQUIREDCHLORINE & CHLORAMINESRULES 62-550.514(1) & 62-550.821MONTHLY FOR SYSTEMS ADDING CHLORINE OR CHLORAMINES NOT REQUIREDCHLORINE DIOXIDERULES 62-550.514(1) & 62-550.821DAILY FOR SYSTEMS ADDING CHLORINE DIOXIDETOTALTRIHALOMETHANES &HALOACETIC ACIDS(FIVE) – STAGE 1 MCLRULES 62-550.500(3),550.514(2), & 62-550.821GROUNDWATERSYSTEMSQUARTERLY FOR SYSTEMS ADDINGA DISINFECTANT & SERVING≥10,000PEOPLE & ANNUALLY DURINGMONTH OF WARMEST WATERTEMPERATURE FOR SYSTEMSADDING A DISINFECTANT & SERVING<10,000 PEOPLEANNUALLY DURING MONTH OFWARMEST WATER TEMPERATUREFOR SYSTEMS ADDING ADISINFECTANTQUARTERLY FOR SYSTEMS ADDING ADISINFECTANT & SERVING≥10,000PEOPLE & ANNUALLY DURING MONTHOF WARMEST WATER TEMPERATUREFOR SYSTEMS ADDING ADISINFECTANT & SERVING<10,000PEOPLENOT REQUIREDSUBPART HSYSTEMSQUARTERLY FOR SYSTEMS ADDINGA DISINFECTANTQUARTERLY FOR SYSTEMS ADDINGA DISINFECTANT & SERVING≥500PEOPLE & ANNUALLY DURING MONTH OF WARMEST WATER TEMPERATUREFOR SYSTEMS ADDING A DISINFECTANT & SERVING<500 PEOPLENOT REQUIREDDEP 2007 DRINKING WATER STANDARDS, MONITORING 62-550AND REPORTINGEffective 9-18-0782CONTAMINANT OR DISINFECTANTRESIDUAL GROUPCOMMUNITY WATER SYSTEMSSERVING MORE THAN 3,300 PEOPLECOMMUNITY WATER SYSTEMSSERVING 3,300 OR FEWER PEOPLENON-TRANSIENT NON-COMMUNITYWATER SYSTEMSTRANSIENT NON-COMMUNITYWATER SYSTEMSCHLORITE – STAGE 1 MCLRULES 62-550.514(2) & 62-550.821DAILY AT ENTRANCE TO DISTRIBUTION SYSTEM & MONTHLY IN DISTRIBUTION SYSTEM FOR SYSTEMS ADDINGCHLORINE DIOXIDENOT REQUIREDBROMATE – STAGE 1 MCLRULES 62-550.514(2) & 62-550.821MONTHLY FOR SYSTEMS ADDING OZONE NOT REQUIREDVOLATILE ORGANICSRULES 62-550.500(3) & 62-550.515QUARTERLY OR, IF AUTHORIZED,ANNUALLY DURING THE FIRST YEAROF EACH THREE-YEAR COMPLIANCEPERIODQUARTERLY OR, IF AUTHORIZED,ANNUALLY DURING THE SECONDYEAR OF EACH THREE-YEARCOMPLIANCE PERIODQUARTERLY OR, IF AUTHORIZED,ANNUALLY DURING THE THIRD YEAROF EACH THREE-YEAR COMPLIANCEPERIODNOT REQUIREDSYNTHETIC ORGANICSRULES 62-550.500(3) & 62-550.516QUARTERLY DURING THE FIRSTYEAR OF EACH THREE-YEARCOMPLIANCE PERIOD.
