At recent city council meetings, residents have asked about the chemical compounds called triha- lomethanes, or THMs, but offi- cials say they are hesitant to do anything about them because of the pending sale of the system to Indian River County. Although Sebastian has a per- mit and money set aside to cor- rect the problem, officials say the risk of getting cancer is not great and the water and sewer system probably will be in the county's hands by the time the corrective work could begin. "(County officials) would have no need to keep the Filbert Street plant and therefore it would not be money wisely spent at this time, since it may never even have a chance to be on line," Pub- lic Works Director Richard Vo- tapka said. THMs form when chlorine re- acts with natural organic sub- stances in raw groundwater. The city first learned of the THMs in 1990 when residents of a Beach Lane house complained to county health officials about a sick child and green -tinted water. Tests showed extremely high levels of chlorine, the agent used to disinfect groundwater at the Filbert Street water plant. The chlorine apparently corroded the copper piping in the house, caus- ing copper contamination. trihalomethanes — something As- sistant County Environmental Health Director Glenn Schuessler said are a problem with many small South Florida water sys- tems that draw from a shallow aquifer. He described the risk to residents as "minimal." The U.S. Environmental Protec- tion Agency allows up to 100 parts per billion of THMs. Votapka said Sebastian's levels range from 140- 240 parts per billion. Although that is greater than what the EPA allows, the agen- cy's rules don't apply to systems like Sebastian's with less than 10,- 000 customers. Sebastian serves more than 1,650 households or about 4,100 people. To be at risk, someone must drink two liters of water every day, 365 days a year, for 70 years and then 1 in 10,000 people may contract cancer, according to EPA projections, Votapka said. The chances of getting hit by lightning in Florida are greater, he said. As part of its bond agreement on the water and sewer system, the city had set aside $22,000 to correct the THM problem, Vo- tapka said, with a system that would inject ammonia into the raw groundwater. The process, used with clorination, eliminates the chlorine -organic reaction that creates THMs. The city applied to the state De- partment of Environmental Pro- tection last July for a construction permit to build the system to rid the water of THMs, he said. the system was to be sold in mid- March and then in April," Vo- tapka said. Votapka sent a letter April 14 to Hal Schmidt, vice president of Or- lando -based Hartman & Associ- ates, the city's water and sewer consultants. The letter asked him to begin soliciting bids. But Votapka did not hear from Schmidt until recently. "Hal is keenly aware of the fact that the city is trying to sell the system to the county," he said. Even if the work had started in April, the city still would need an operating permit from the DEP and that could take three to six months depending on the infor- mation agency officials required, Votapka said. So, the correction system would not be running until the fall and officials said they ex- pect the transfer to the county t take place before then. "The system really wouldn't b on long enough to have any majo benefit when you look at the ris factor over 70 years," Votapk said. "When you look over the for gevity of the risk over 70 year: certainly no one's going to be o the system that long." Schuessler said people are at "minimal" risk, but said th county will take care of the prol lem one way or another. "Eventually something needs t be done," he said. County Utilities Director Terr Pinto said if the county takes ove the system, the Filber Stree plant will be dismantled immed', ately and customers would b hooked to the county's water plar at Hobart Park.

Indian River County -PW Sebastian Highlands Proposed Chlorammoniation PATS Number 254413 Dear Mr. ReVoir: Virginia S. Wetherell Secretary Your application for a permit to construct the referenced water treatment plant modifications was received on July 15, 1994. In accordance with Rule 17-555.520 of the Florida Administrative Code, we are unable to complete processing of your application because the following items are needed: 1. It appears that manual adjustment of the ammonia feed rate is proposed. This plant only requires six hour per day operator staffing and "visits" on each weekend day. Does the plant operate in the absence of operator staffing? If so, does the flow rate vary? If so, describe how the ammonia gas feed rate will be proportioned to the flow for both prefiltration and postfiltration injection points during those periods when an operator is not present. 2. Regarding operator safety, describe how the operator will be aware of a leak prior to entering the ammonia storage room. Also, how will the room be ventilated? r.l Rule 17-555.320(1), Florida Administrative Code, requires that a -./l plan be submitted prior to the modifications, to include the following: "a. An evaluation of the water system for sanitary defects and the source water for bacteriological quality. b. An evaluation of its treatment practices and the proposed improvements that will minimize disinfectant demand and optimize finished water quality throughout the distribution system. 3. (Continued) w'•�+ °�^'�- ' �`� C. Analyses of heterotropic plate counts, as appropriate, plcl'7s before the modification. 1, 7, d.

In accordance with Rule 17-555.520 of the Florida Administrative Code, we are unable to complete processing of your application because the following items are needed: 1. It appears that manual adjustment of the ammonia feed rate is proposed. This plant only requires six hour per day operator staffing and nvisits" on each weekend day. Does the plant operate in the absence of operator staffing? If so, does the flow rate vary? If so, describe how the ammonia gas feed rate will be proportioned to the flow for both prefiltration and postfiltration injection pointe during those periods when an operator is not present. 2. Regarding operator safety, describe how the operator will be aware of a leak prior to entering the ammonia storage room. Also, how will the room be ventilated? 3. Rule 17-555.320(1), Florida Administrative Code, requires that a plan be submitted prior to the modifications, to include the following: "a. An evaluation of the water system for sanitary defects and the source water for bacteriological quality. b.

This plant only requires six hour per day operator staffing and "visits" on each weekend day. Does the plant operate in the absence of operator staffing? If so, does the flow rate vary? If so, describe how the ammonia gas feed rate will be proportioned to the flow for both prefiltration and postfiltration injection points during those periods when an operator is not present. Response #1: The City of Sebastian operates the Sebastian Highlands WTP approximately a hours per day (0700 to 1500). During the 8 hour work shift, the potable water supply for each day is produced and stored in the 0.50 MG ground storage tank on- site. Potable water demand to the system is supplied automatically by high service pumps from the ground storage tank during the entire day. Each morning, the operators activate the potable water wells and lime softening plant to refill the 0.50 GST. The tank provides more than sufficient capacity for the demands on the remaining 16 hours. It is anticipated that the operators will manually activate and deactivate the ammoniation system in conjunction with the other treatment facilities during the 8 hour shift. This procedure is anticipated to provide and ensure accurate feed rates and overall system safety_ Since the other treatment facilities are not operated during the un -manned 16 hour period, the ammonia system. It is anticipated that the main feed point will be postfiltration. The prefiltration feed point will be provided to offer system flexibility_ Comment #2: Regarding operator safety, describe how the operator will be aware of a leak prior to entering the ammonia storage room. Also, how will the room be ventilated. 08/02/94 10:46 $407 839 3790 HARMAN ASSOC 11003/003 Response #2: The ammonia leak detector indicated on the drawing will be connected to an audible and visual alarm at the storage room. A ventilation fan and several cross vent louvers will be provided in the building to ensure proper ventilation. Comment 43: Rule 17-555.320(1) Florida Administrative Code, requires that a plan be submitted prior to modifications, to include the following: a_ An evaluation of the water system for sanitary defects and the source water for bacteriological quality. b_ An evaluation of its treatment practices and the proposed improvements that will minimize disinfectant demand and optimize finished water quality throughout the distribution system. C. Analyses of the heterotropic plate counts, as appropriate, before the modification. d. Assurance that an active disinfectant residual will be present throughout the distribution system during the modification_ Response #3: a.The City of Sebastian samples for source water quality at the appropriate intervals required by the Department. The proposed improvements will not affect the water quality with respect to sanitary or bacteriological quality. .The City currently provides aeration, lime softening, filtration and chlorination treatment of the raw water supply. This process provides a high level of treatment and greatly reduces the disinfectant demand in the water supply. The City --+peridically flushes the drinking water system via the fire hydrants to eliminate any stagnant water or settled material which may cause disinfectant demand. CIt does not appear necessary at this time to provide a heterotropic plate count before the modification. d.The City of Sebastian will monitor the chlorine residual during start-up and continually following the proposed modifications. Comment 44: Describe the plan for notifying residential and commercial customers prior to start-up with respect to owners of aquariums and dialysis machine. Response #4: The City of Sebastian intends to notify the residential and commercial customers through mailing fliers, public notices in the local newspaper and through notices in and at public places.

(GDU) Public Notice, which was folded and put into the bills as a bill stuffer to all the customers of the GDU system. Also, this notice was printed in the newspaper for local distribution twice prior to the conversion to the ammoniation system. The first time it was put into the newspaper was one month prior to conversion, and the second was two weeks prior to conversion. The notice was also published in the Palm Bayer, which is the City's newspaper. The City cooperated with GDU at the time in disseminating this notice. In an effort to have as many things accomplished in a rapid manner, I am providing you a copy of the notice such that you can rework it to your satisfaction and coordinate the public notification activities which would be required in conversion from a free to a combined chlorine residual.

PUBLIC NOTICE TO: OWNERS OF TROPICAL FISH AND OPERATORS OF MEDICAL DIALYSIS FACILITIES: General Development Utilities is advising owners of tropical fish and operators of med. 'ical dialysis facilities and other chlorine -sensitive processes that current procedures to test for and remove chlorine from the Port Malabar water supply system may no longer be effective. In early March, 1983 General Development Utilities will modify its water treatment Process in order to comply with new state and federal regulations. The modification involves changing disinfectants from chlorine to chloramine. As used in public water supplies, chloramine is, like chlorine, harmless to humans but can adversely affect some aquatic species and certain chlorine -sensitive processes such as dialysis. Problems arise because test procedures used to detect and measure chlorine may not indicate the presence of chloramine. Also, the technique of "aging" water to dissipate chlorine before use in aquariums is not advisable, because chloramines are more persistent than chlorine. Water disinfected with chloramine can be used safely for all applications if certain precautions are followed. General Development Utilities urges its customers who may be affected by this change to seek advice from professional aquarists or medical authorities competent to give such advice. On the positive side, chloramines will provide longer lasting protection against water- borne disease organisms without the strong taste and odor of chlorine. Further, chloramine will not produce chloroform and other byproducts which are potential human carcinogens. Please watch your local daily newspaper for the date in which the change to chloramines will occur, or call our local office at 723-2877 if you have any questions.

The DBP's which cause the most concern are trihalomethanes (THM's). This report shall investigate the amount of THM's being produced, as well as discuss several methods which can be used to control the production of THM's. Finally, a method shall be determined that is most suitable to the needs of the Sebastian Highlands Water Treatment Plant in terms of the control of THM's to ensure compliance within the current regulatory environment. `r „ ('L'�- 1.2 BACKGROUND JUN f yys :�,,,. lo, uuo �e. • ,�, � ,,µb�j The City of Sebastian is the second most populated mumicipalY in Indian River County, Florida, and is loated in the northeast comer of the County on the west lc of the Indian River. The most significant land use feature of the City is the large number of vacant platted residential lots. There e,approximately 14,170 platted residentiaYlots of which 5,022 are improved and the remaining 9, 148 are unimproved. The large number of platted residential lots are the reason that the City'is expected to become the most populous municipality in the County during the next 15 years This suburban land.�pattem dominates the southern and western limits of the city. The second most dominant land usage is the municipal airport, which is located in the northwest portrof the City. The land usage east of the airport consists primarily of undeveloped land that ii currently The for industrial use. Commercial land usages are concentrated along the U.Sc'Higbway 1 corridor in the northern portion of the City. The eastern boundary of the City has an irregular shape bordering the western shoreline of the Indian River. Land use is primarily residential except for the commercial usages that are present along the U.S. Higlfway 1 corridor and the Indian River from the north to south City limits. The total available water service area of\the system encompasses the entire incorporated limits of tP6/city.

This situation typically occurs in a(WTI') proees` following disinfection. THM formation is a time function reaction. The quantity of THM's formed depends on the amount of precursors in the water, the concentration of free residual chlorine in the water, and the total time the precursors and the free chlorine are in contact with each other. THM's will continue to form until either the THM precursors or the free chlorine are completely consumed. Trihalomethane limitations in drinking water are regulated bj�F�➢£P'Chapter 17-550. Current regulations require that the ,etotal trihalomethane maximum contaminant level (MCL) not P- lir) exceed 100 ug/1 for samples taken utilities wi(h groundwater sources i" at eSJdT.b� 11� 10,000 to 74,999 people. Total THM's include bromodichloromethane, dibromochloromethane, tribromomethane, and trichloromethane. Because of the health risks associated with the presence of THM's in drinking water, regulatory agencies have recently discussed the need of lowering the current MCL of 100 µg/L to as low as 50 µg/L. The t a ° Sebastian Highlands Water System serves much less than 10,000 people (approximately 3 0001f and is therefore not subject to this requirement. However, the City of Sebastian is concerned with the possibility of elevated levels of THM's and wishes to explore various methods of controlling them. L^ k" - Z� ( e, r-- 2.2 = 2.2 EXISTING WATER SYSTEM This section discusses the existing sources of raw potable water, methods of potable water treatment, finished water storage and distribution of potable water to the residents of the City of Sebastian. In addition, this section discusses information pertinent to the overall operation of the potable water treatment, transmission and distribution facilities. SC/dt/pt/R-S-2/Sec2.rpt HAI#92-023.11 2-1 042894 2.2.1 RAW WATER SOURCE The source of raw water fqr e Seb tian Highlands water system is the surficial aquifer. cl I s of + i 1 i tear+ ) 1 a.+_. 100 F� ctt-e.Q. With respect to raw water withdrawals, the Sebastian Highlands water system is currently regulated by the St. Johns River Water Management District (SJRWMD). The SJRWMD is a governmental agency created by the Florida Legislature which has the responsibility of managing the water resources within its boundaries (i.e., central and northeast Florida). The SJRWMD authorizes the use of the groundwater from the surficial aquifer pursuant to water use permit #2-061-0142 UNR. The Sebastian Highlands water permit #2-061-0142 UNR. authorizes withdrawal withdrawal up to 1.690 mgd and expire on June. 1994. However, based -ear w discussions with the SJRWMD, it is not anticipated that the City v mid experience any difficulty with respect to the renewal of the water use permit at existing consumption levels reflected in the current permit, as well as for future consumption levels based on normal growth. Tt� over_n_ ing-Board of the SJRWMD has declared the enter }R'4VIvID as a Water Conservatio�ea Aywhich requires action to_addr_ess c alive water withdrawals that are -eausing-"-may-cause- erse _ the water an related resources or_public-interest. In,accordance with the SJR tr►ut�the flee which in this case is the City, -must - _ -- - -- develop and -submit to the SJRWMD for water conservation within the SerJice ea duringine-perretir-rerfewal-process plan detail speeife�steps According to SJRWMD, the available water supply is of adequate quantity and quality and should provide a sufficient long term supply of water, assuming proper water use planning. The water quality of the groundwater supply is such that it requires only aeration for removal of hydrogen sulfide, lime softening for removal of hardness, and chlorination for disinfection to meet the requirements of Rule 17-550, of the Florida Administrative Code (FAC) as it relates to finished potable water quality standards and the Safe Drinldng Water Act of 1986. Raw water for treatment at the Sebastian Highlands Water Treatment Plant (WTP) is pumped from two (2) shallow wells located at or near the WTP site. Raw water supply Well No. 1 is located on Filbert Street just north of the WTP site. Well No. 2 is located on the WTP site. SC/dt/pt/R-S-2/Sec2.rpt HAI#92-023.11 2-2 042894 Each well is 10 -inches in diameter, approximately 100 -feet deep and equipped with a vertical turbine pump, each with a rated capacity of 600 gallons per minute (gpm). The City of Sebastian operates a 100,000 gpd prefabricated steel,water treatment plant at Park Place. Raw water supply for the Park Place WIT is pumped from two (2) wells located on the plant property. The primary well is 6 -inches in diameter with a 3 -inch drop pipe. and is capable of pumping 1109,500 gallons per day (gpd). The secondary or back-up, well is 4 -inches in diameter with a �- inch droppipe and is capable of pumping 96,500 gpd. l/ The Sebastian Highlands WTP has a rated capacity of 671,000 gpd. Currently, the WTP is experiencing flow demands of approximately half of its rated capacity. Due to the fact that each of the two (2) well pumps at the plant site are capable of pumping 600 gpm, and that raw water supply capacity problems such as water table drawdown due to overpumping have not been experienced, raw water supply capacity does not appear to be a problem. In the future, additional raw water supply wells may have to be identified and constructed due to increasing demands resulting from factors such as the incorporation of the Park Place/Palm Lake Club service area into the City of Sebastian service area and increasing population trends in the City of Sebastian service area. It should be noted that at this time there are no problems associated with the Sebastian Highlands WTP supplying potable demand capacity to the City of Sebastian service area. The historically low potable demands experienced at the Park Place WTP are not expected to significantly affect the capability of the Sebastian Highlands WTP in treating the additional demand resulting from combining the flows. The current water demand at the Park Place WTP is small and the plant is proposed to be decommissioned upon completion of the Park Place and Sebastian Highlands WTPs interconnect project. Based�od data obtained from the Florida Depar�tinent of Environmental P otectioa,(?j EP) Monthly Operating Reports (MOR), the quality/of-raw water -that is pumped to the Sebastian Highlands TP is considered good. This data indicates that the total hardness over/ the I V5. years Whas averaged 260 mg/1 expressed irr milligrams,per liter (mg/1) as calcium carbonate, ACACO3). The. raw water pH has averaged 7.2 over the past 5; years. Botiv the raw wat hardness and pH level , e acceptablq:�and do notpresent a problem in terms of treatability 7at vthe cumt WTP facilities. SC/dt/pt/R-S-2/Sec2.rpt HAI#92-023.11 2-3 042894 2.3 WATER TREATMENT PLANT o., S{It Two (2) water treatment Plants are operated by the City of Sebastian, the Park Place WTP and the Sebastian Highlands WTP. These WTPs are currently operated independently of each other. Future plans include incorporation of the two WTP's into the same system by means of a pressurized interconnection, main. Interconnection of these two WTP's is planned to occur by September, 1994. The City operates a 100,000 gallon per day prefabricated steel water treatment plant which provides potable water to the Park Place/Palm Lake Club service area. There are two (2) wells located on the plant property. The primary well is 6 -inches in diameter with a 3 -inch drop pipe and is capable of pumping 109,500 gpd. The secondary, or back-up well is 4 -inches in diameter with a 2 -inch drop pipe and capable of pumping 96,500 gpd. Raw water is pumped to a tray aerator on top of a 32,320 gallon groundwater storage tank where the water is chlorinated by a gas chlorination system. The plant equipment consists of two (2) 20 horsepower (hp) pumps which pump the water into a 5,500 gallon hydropneumatic tank. Liquid levels and pressure in the system are maintained by pressure switches. Presently, the pressure in the system fluctuates between 42 psi and 62 psi. A contact Class "C" operator operates the plant. The Sebastian Highlands WTP on Filbert Street was constructed in 1982. The primary modes of water treatment include aeration, lime softening, filtration and disinfection. As the raw water from the two (2) supply wells enters the precipitator, Moor Floc 300FL polymer is added after the natural draft tube/cascade aerator for improved water softening. The natural draft tube/cascade type aerator is utilized primarily for hydrogen sulfide removal. The cascade type aerator consists of four (4) trays and has a maximum capacity of 1,800 gpm. From the cascade aerator, the raw water flows to the solids contact precipitator. Currently, operation requires addition of Moor Floc 300FL polymer and a lime slurry to the influent at the solids contact precipitator to reduce hardness in the raw water, as well as enhance the settling characteristics of the solids produced. The solids contact precipitator was manufactured by Permuttit and is 40 feet long by 12 feet wide, with a sidewater depth,, of approximately 9 feet.

The present transmission and distribution system was installed up 4013' years ago coincident with the growth and development of the utility system. i% 2.4 TRIHALOMETHANE FORMATION POTENTIAL Recently, a site visit to the Sebastian Highlands WTP was made by engineers from Hartman & Associates, Inc. (HAI). During this visit, samples from the water treatment plant were taken to test for THM formation potential (THMFP). The first sample was taken after aeration and prior to the precipitator, the second sample was taken after the precipitator but prior to filtration. Finally, duplicate samples were taken after filtration. Since chlorine is injected downstream of all the collection points, no chlorine had been in contact with the samples. T DJFP testing was performed by Bionomics Laboratory, Inc. THMFP is determined by dosing the samples with a chlorine conce similar to the concentrations used at the WTP. In this case, the chlorine dose was /i The reaction is then allowed to proceed for a predetermined time span. At that point, the reaction is terminated using sodium thiosulfate, and the sample is tested for THM concentration. For the four (4) samples that were analyzed, the reaction times were as follows: • 5 -minutes �7(� • 15 -minutes • 30 -minutes • 60 -minutes • 120 -minutes • 240 -minutes • 480 -minutes The results of the THMFP analysis are summarized in Table 2-1. When the THMFP results are plotted versus time, a growth curve can be developed. This curve is illustrated in Figure 2-1. Also shown on the curve is the line representing the current 100 µg/L maximum contaminant level (MCL) for THM's. The point at which the growth curve crosses the 100 µg/L MCL line indicates the maximum amount of time,yee�wr¢ to treat for THM formation and still keep below the MCL. This is useful when analyzing the various treatment alternatives available with respect to the THMFP at the different test points in the WTP system. Some tests suggest that the filtered water will have a higher THMFP growth curve SC/dt/pt/R-S-2/Sec2.rpt HAIN92-023.11 2-7 042894 water quality but directly proportional to ozone dosage. When sufficient ozone is introduced, ozone is a more complete disinfectant than chlorine. Ozone is an air pollutant which can discolor or kill vegetation. Residual ozone in off -gas streams must be processed for ozone decomposition prior to release. Ozone is also toxic when inhaled in sufficiently high concentration in air. Organic removal is improved with combined ozonation and ultraviolet radiation. it is postulated that the UV activates the 03 molecule and may also activate the substrate. Ozone -UV is effective for the oxidation destruction of pesticides to terminal end products of carbon dioxide and water. As with any disinfection process, water containing high levels of suspended solids may require filtration to make ozonation more cost-effective. Ozonation is applicable where chlorine is either deficient or where chlorine disinfection produces potentially harmful chlorinated organic compounds (such as trihalomethanes). In many ways, the desirable properties of ozone and chlorine as disinfectants are complementary. Ozone provides fast acting, germicidal and viricidal potency, commonly with beneficial results regarding taste, odor, and color. Chlorine provides sustained, flexible, controllable germicide action and will retain a residual in water supplies. Thus, it would seem that a combination of ozonation and chlorination might provide an almost ideal form of water supply disinfection. daa ^-+} pm�Id_t +t" 1; i"` vgiv vr4:w A3 C.I110 rr:e. �S Osawt 40,13 Ho+ P,av:ots. a �n..c. etildv-.I S P. 3-10 Chlorine dioxide also provides good organic destruction, but complete destruction can not be achieved.

Potassium permanganate will cause water to turn pink at higher dosage levels. This treatment process is more -efficient at pH's which are slightly basic. The final method which was investigated was the use of ozone in conjunction with ultraviolet light irradiation. It has been shown that when ultraviolet light is used with ozone, the SC/dt/pdR-S-2/Sec3. rpt HAIN92-023.11 3-5 050694 J 200 z O 180 1= Q Ir 1s0 F_ z U 140 z 0 120 W Q 100 2 F - Lu 80 2 O J 60 Q 40 J 20 O H ...................................................................................................................

Chlorine solution is currently fed just prior to the clearwell which is located upstream at the storage facility. This location is best for the Sebastian Highlands WTP since it will allow the shortest contact time between the THM precursors and free chlorine residual, which will minimize THM levels in the distribution system. Prechlorination, which is occasionally done to remove hydrogen sulfide from the raw water, is not presently included in the treatment process at the Sebastian Highlands WTP and should be avoided as this practice would only increase THM production. SC/dt/pt/R-S-2/Sec2. rpt HAIN92-023.11 2-8 042894 SECTION 3 3.1 INTRODUCTION There are three ways in which THMs can be controlled in a potable water treatment system. These methods include 1) removing the THM precursors prior to disinfection; 2) alternate disinfection techniques; and 3) removing THM's after they have formed following disinfection. Each of these approaches has advantages and disadvantages, as well as different degrees of effectiveness in terms of removal efficiency and cost. 3.2 TECHNIQUES FOR REMOVING THM PRECURSORS Because trihalomethanes are formed when free chlorine is added to water containing THM precursors, one approach to lowering THM concentrations would be removal of the precursors themselves. 3.2.1 Clarification (Coagulation) Although coagulation is most often considered a treatment technique for softening, color and turbidity removal, the process plays a very significant role in the removal of organics as well. This role occurs both because some organic materials are probably adsorbed on suspended particles, and because the negatively charged colloidal particles resulting from the natural decomposition of humic materials (usually recognized as color), can be removed by coagulation with the aid of salts, such as aluminum or iron. Removal of organics by coagulation is best under slightly acidic conditions. Three types of clarification methods have been identified as capable of removing organics: 1) Coagulation 2) Precipitative softening 3) Direct filtration The existing Sebastian Highlands Water Treatment Plant currently utilizes precipitative softening followed by sand filtration. Therefore, the present system provides for the removal SC/dt/pt/R-S-2/Sec3.rpt HAI//92-023.11 3-1 050694 of precursor material to a certain degree. All three (3) methods have been reported to provide removal of up to 50 percent of the THM precursors formed from non-volatile organic compounds. Tests indicated that removal of 50 percent of the THM precursors has been sufficient in limiting the formation of THM's to levels below the current MCL of 100 µg/L. Tests have also indicated that additional removal efficiency will occur if the pH is adjusted within the pH range for a minimum solubility of the metallic hydroxide coagulant. This is usually accomplished by adjusting the pH between 4 and 6. It should be noted that the coagulant aided clarification and softening processes described above and will result in the formation of sludge that will have to be addressed in terms of further treatment or disposal. Solids removal through the use of sand media filtration is another method of THM precursor removal. Sand media filtration can remove THM precursors to levels that are sufficient in limiting the formation of THM's to below the current MCL of 100 µg/L. The major drawbacks to the use of sand media filtration for THM precursor removal are those concerning increased THM precursor concentrations after filtration due to inefficient backwashing of the filters to remove the precursors collected in the filters. Drawbacks such as these may be eliminated by adjusting filter run times, backwashing procedures and sand media replacement schedules. 3.2.2 Source Control When possible, utilities should examine the quality of their raw water source to determine whether or not operational changes could be made to improve the quality, and thereby, lower the concentration of THM precursors. Since the raw water source for the Sebastian Highlands Water Treatment Plant is from the surficial aquifer, the source is difficult to control. The only option might be to develop an underground fresh water barrier created by injection wells or spreading basins to reduce the type and concentration of THM precursors in the raw water. 3.2.3 Aeration Because the primary THM precursors are known to be high molecular weight humic and fulvic acids, aeration would not be expected to be effective for non-volatile precursor removal. However, THM precursors that exist as volatile organic compounds (VOC's) may be removed SC/dt/pt/R-S-2/Sec3.rpt HAIN92-023.11 3-2 050694 partially or totally by air stripping. This is accomplished to a certain extent in the present system by the gravity cascade aerator at the head of the plant. However, more effective removal of VOC's is typically accomplished using air stripping by counter current, forced draft, spicy aeration or packed tower aeration. These types of aerators are more efficient than gravity cascade aerators, but are more expensive in terms of equipment costs and pumping costs, and have the drawback of being limited to the removal of those THM precursors that exist as VOCs. The THM precursors that exist in this form are reported to be less than 10 percent of the total amount of the THM precursors. It should be noted that the aeration techniques described above are ineffective in the removal of the higher molecular weight non-volatile THM precursors which make up the majority of THM precursors. 3.2.4 Oxidation Two goals are desirable when oxidants are used to control THM precursors: 1) Chemical alteration the precursor materials, 2) Complete chemical oxidation of the precursors to carbon dioxide. Oxidants which have shown reduction of THM precursors are ozone, chlorine dioxide, potassium permanganate, and ozone/ultraviolet radiation. It should be noted that the use of some oxidants can result in the formation of oxidation byproducts, potentially as harmful as THM's. Ozone (03) may be used for disinfection and oxidation of organics in water treatment plants. As a disinfection (dosages of 3 to 10 mg/L are common), ozone is an effective agent for deactivating common forms of bacteria, bacterial spores, and vegetative microorganisms, as well as eliminating harmful viruses. Additionally, ozone acts to chemically oxidize materials found in the water and can reduce the BODS and COD, forming oxygenated organic intermediates and end products. Ozone treatment also reduces water and wastewater color, odor, and taste. SC/dt/pUR-S-2/Sec3. rpt HAI//92-023.11 3-3 050694 Ozone injection into the wastewater flow is accomplished by mechanical mixing devices, countercurrent or co -current flow columns, porous diffusers or jet injectors. Ozone acts quickly and consequently, requires a relatively short contact time. Ozone has been found to be a good oxidant for removal of cyanide, phenol, and other dissolved toxic organic materials. Combination of ozonation and activated carbon treatment can achieve 95 percent chloroform and other trihalomethanes removals. Ozonation may not be economically competitive with chlorination under some conditions. Although ozone is effective in disinfecting water, its use is limited by its solubility. The temperature of water being treated determines the amount of ozone that can be dissolved in water. In addition, ozone residuals cannot be maintained in metallic conduits for any period of time because of ozone's highly reactive nature. The inability of ozone to provide a residual in the distribution system is a major drawback to its use. Ozone has been used in the water industry since the early 1900s particularly in France, and it has been fully demonstrated but not widely used in the U.S. because of its relatively high cost. Recent developments in ozone generation have lowered the cost, thus making it more competitive with other disinfection methods. The ozone disinfection system is a complex series of mechanical and electrical units, requiring substantial maintenance, and is susceptible to a variety of malfunctions as is chlorine gas delivery. In the case of ozonation however, data on consistent, long-term experience are relatively unavailable, especially for large plants. It is not possible to assess long-term maintenance requirements for equipment, compressors, cooling and drying equipment, and other appurtenances. It is estimated that power requirements are between 8 and 10 kWh/lb of ozone generated. Monitoring requirements are similar to those for UV disinfection and chlorination, including bacterial analysis and routine ozone monitoring. Ozone breaks down to elemental oxygen in a relatively short period of time (half life about 20 minutes), therefore, it is difficult to store. Consequently, it is generated on site using air as the oxygen source. The ozone generation process utilizes an electric arc, or corona, through which air or oxygen passes, yielding a certain percentage of ozone. Automatic devices are commonly applied to control voltage, frequency, gas flow, and moisture, all of which influence the ozone generation rate. Effectiveness of disinfection is inversely correlated with SC/dt/pt/R-S-2/Sec3.rpt HAIH92-023.11 3-4 050694 effectiveness of the ozone is increased. The amount of time it takes ozone to destroy THM precursors can be reduced by 50 percent with the use of ultraviolet irradiation. Therefore, increased quantities of UV energy enhance the removal of precursors when ozone is used. 3.2.5 Adsorption Because THM precursors are a mixture of many organic chemicals, and this mixture varies depending on the source waters characteristics, adsorption from a theoretical standpoint is much more difficult than treating individually identifiable and quantifiable trihalomethanes themselves. Much unlike the individual THMs, the characteristics of the acidic THM precursor materials are influenced by numerous variable weight distribution, pH, organic ion concentration, THM precursor source, and the relative fractions of humic and fulvic acids. Three mediums were analyzed as to their effectiveness at THM precursor removal: 1) Powdered activated carbon (PAC) 2) Granular activated carbon (GAC) 3) Synthetic resins (Ambersorb XE -340) Powdered activated carbon is directly dosed to the water source and mixed to create a type of slurry. It is then centrifuged and the supernatant decanted. In general, it has been found that doses of PAC much higher than conventionally used in existing water treatment processes seem to be required to obtain significant removal of THM precursors. PAC does provide some synthetic organic compound removal. Sludge disposal is a problem because the PAC can not be reactivated but can only be used once. Granular activated carbon provides good to very good removal of THM precursors. Removal is nearly complete when the sorbent is fresh, but as the activated carbon reaches exhaustion, the removal efficiency of the carbon decreases. It has been shown that GAC will remove some synthetic organic compounds. Drawbacks to the use of GAC are that the carbon must be reactivated often, and there are possible corrosion problems associated with low total organic carbon concentrations. Synthetic resins, specifically Ambersorb XE -340, have been found to be partially effective for the removal of THM precursors and THM's that would be produced if allowed to react with SC/dt/pt/R-S-2/Sec3.rpt HAIH92-023.11 3-6 050694 free chlorine. Tests have shown that the synthetic resins are ineffective in the removal of the THM precursors in water which has been treated by the lime softening techniques. 3.2.6 Ion Exchange Because synthetic ion exchange resins designed for other purposes are often reported to become fouled with organic contaminants while in service, they have been examined for the use of THM precursor removal. Also, because humic acids are anionic, especially as water becomes more alkaline, anion exchange resins were thought to be a possible alternative for the removal of THM precursors. Two types of resins are considered in this sub -section, strong -base and weak -base anion exchange resins. The strong -base anion exchange resin is quite effective for removing THM precursor materials. However, as mentioned in sub -section 3.2.5, the resin is ineffective in the removal of precursors after the addition of lime for softening purposes. The weak -base anion exchange resins also show significant precursor removal rates and are not affected by lime addition. These resins must be regenerated approximately every 6 to 7 days with lime and hydrochloric acid. The process of regeneration may result in the formation of hazardous wastes and the complexities associated with the disposal of such wastes. 3.2.7 Biological Degradation Biological degradation has been observed in GAC beds after the GAC has reached steady state condition. Biological degradation is the process in which microorganisms use the precursor materials, either adsorbed on the carbon surface or in the passing water, as a substrate, or food. Ozone can be used preceding the adsorption step to fracture organic molecules and make them more biodegradable. This improves the performance of using adsorption alone by enhancing the natural biodegradation process. 3.2.8 Summary If THM concentrations are controlled by lowering the concentration of precursor materials, free chlorine can still be used as a disinfectant. This is an advantage because free chlorine is currently the most common treatment used in disinfecting water and operators have confidence in its use and ability to produce a microbiologically safe water. Another advantage in SC/dt/pt/R-S-2/Sec3.rpt HAI//92-023.11 3-7 050694 removing precursor material is the reduction of disinfectant demand caused by the presence of less material for which the disinfectant can react. A lower disinfectant demand means fewer disinfection byproducts of both halogenated and nonhalogenated types. For removal of THM precursors to be effective, it must preclude any treatment disinfection processes which utilize chlorine. Also humic acids help to control corrosion of water transmission and distribution systems. Removal of these compounds in an attempt to lower THM precursor levels may result in a more corrosive water. A summary of the different THM precursor removal methods is presented in Table 3-1. 3.3 ALTERNATE DISINFECTION TECHNIQUES When free chlorine reacts with THM precursors, THM's are formed. If no effort is made to remove the precursors prior to disinfection, alternate means of disinfection must be sought out if the production of THM's is not desirable. Alternative techniques may include disinfection by utilizing chloramination, chorine dioxide, ozone, and ultraviolet radiation. 3.3.1 Chloramination Chloramination is the process of adding ammonia to chlorine and forming monochloramine, dichloramine, and in some circumstances, nitrogen trichloride. Chloramines do not react with THM precursors to produce THM's, and are also an effective disinfection agent. With the addition of ammonia to free chlorine, the rate at which the free chlorine is converted to chloramines depends on pH, temperature, and the chlorine/ammonia ratio present. At ideal conditions, the reaction to form chloramines occurs in hundredths of a second. However, at low temperatures and high pH, it can occur at much slower rates. Thus, free chlorine could be present for several minutes and result in the production of THM's. On the other hand, the presence of free chlorine could result in rapid inactivation of microorganisms. Viruses are, however, much more resistant than coliforms to both free residual chlorine and chloramines. Therefore, whether or not the initial rapid inactivation phase would be of sufficient duration to ensure virus destruction would depend on the source characteristics of the water and other treatment processes used. Because of this uncertainly, conversion from free chlorine to chloramine treatment for primary disinfection should not be considered without laboratory analysis of this method to confirm its effectiveness as a disinfectant.

The preferred method to reduce THM levels below 100 µg/l has typically been changing the method of disinfection from free chlorine residual to combined available chlorine or chloramines. Chloramines are produced by adding ammonia shortly after adding chlorine solution. Chloramines do not react with THM precursors to produce THM's, in the finished water. The advantages to disinfection with chloramines are: they are relatively iwe& to produce; they maintain long term residuals in the distribution system; they do not form THM/s; and, they are most effective in high pH waters which makes them especially more advantageous for use after lime softening. The disadvantages to using chloramines as a primary disinfectant are: they are a weaker disinfectant than free chlorine; they are slow reacting; and, they are not as effective at killing viruses. Since chloramines are a weaker disinfectant and they are slower reacting, the FDEP requires a minimum of 2 hours of disinfection contact time when chloramines are used as a primary disinfectant. The contact basin cannot be subject to short circuiting and must be constructed so that the contact time cannot be lowered by changing pumping levels. 3.3.2 Chlorine Dioxide Chlorine Dioxide is a good disinfectant and provides a residual for continued disinfection throughout the transmission and distribution system. However, chlorine dioxide has been shown to produce halogenated byproducts, and for this reason, will not be considered further as an effective alternative to the use of free chlorine as a disinfectant. 3.3.3 Ozone Ozone is a very strong oxidant and, therefore, is an excellent disinfectant. The drawback to the use of ozone is that because of its highly unsuitable nature and tendency to convert back to elemental oxygen, it does not provide a residual and therefore is ineffective as a disinfectant in the transmission and distribution system. SC/dt/pt/R-S-2/Sec3.rpt HAIN92-023.11 3-10 050694 Ozone's inability to produce a residual is the main reason it has not been accepted for large scale use as a disinfectant. Ozone by itself will not react with THM precursors and therefore is effective in the elimination of THM's from a water system. Ozone is more effective when used with other disinfectants such as free chlorine. The ozone being used for the initial disinfection and the free chlorine to provide for a residual in the transmission and distribution system. The drawback to this method is that once you introduce free chlorine to the process, you have the potential to form THM's. In conclusion, disinfection with the use of ozone and free chlorine may be effective if the free chlorine can be limited to levels low enough to ensure that THM formation will not exceed the MCL. 3.3.4 Ultraviolet Radiation (UV) UV is similar to ozone in that it is an effective disinfectant but does not provide a residual in the transmission and distribution system. Like ozone, the usefulness of UV as a large scale disinfectant is its use in some combinations with free chlorine to produce an effective disinfectant that provides a residual but limits the formation of THM's. 3.3.5 Other Disinfecting Techniques A variety of other agents may be used as effective disinfectants. These include heat, extremes in pH, metals (silver, copper), surfactants, and permanganate. Heat is useful only in emergencies, as in "boil water" orders, and is uneconomical. Alkaline pHs (during high lime softening) may provide some microbial inactivation, but are not usually sufficient as a sole disinfectant. Potassium permanganate has been reported to achieve some disinfecting effects, however, the large scale effectiveness of this method has not been well characterized. 3.3.6 Summary Because of the influence of environmental factors on disinfection, precise rankings of the three alternative disinfectants - ozone, ultraviolet radiation, and chloramines - cannot be made. In general, however, ozone and ultraviolet radiation are ranked as strong disinfectants that are nearly equal to or better than free chlorine, even at low pH. Furthermore, in contrast to free chlorine, the disinfecting power of ozone and UV is not reduced by increasing pH. Chloramines are generally ranked as weaker disinfectants than free chlorine but are adequate in SC/dt/pt/R-S-2/Sec3.rpt HAIN92-023.11 3-11 050694 many cases, and have been utilized successfully as disinfectants by same abilities. A summary of alternate disinfection methods is shown in Table 3-2. 3.4 TECHNIQUES FOR REMOVING THM's If the removal of THM precursors and alternative disinfection practices are not feasible, and the formation of THM's is a problem, then the THMs themselves must be removed. Two methods that can be used are aeration and adsorption. 3.4.1 Aeration Among several factors influencing the effectiveness of removing organic compounds from water by aeration are contact time, air to water ratio, temperature, vapor pressure, and solubility of the contaminants. Both diffused air and tower aeration have good to very good removal of THMs, but bromine containing THMs are harder to remove than chloroform. The only advantage of tower aeration over diffused aeration is that with tower aeration, high air to water ratios can be achieved. However, with diffused aeration, longer contact times are achieved. Depending upon the amount of contaminants being removed, air pollution could be a problem and the emissions may be regulated. 3.4.2 Adsorption Both powder activated carbon (PAC) and granular activated carbon (GAC) provide good removal of THMs. With PAC, bromine -containing THM's are better adsorbed than chloroform. Removal is influenced by influent THM concentration and the loading is proportional to the influent concentration. Some inadequacies and strong points concerning the process of absorption were discussed in Subsection 3.2.5 and also apply to the discussion of absorption in the process of THM removal. 3.4.3 Summary As a treatment approach, the removal of trihalomethanes has some advantages. The most important are that the water utility would not need to change its disinfection practices and the SC/dt/pt/R-S-2/Sec3.rpt HAI#92-023.11 3-12 050694 TABLE 3-2 CITY OF SEBASTIAN AMMONIATION SYSTEM DESIGN DISINFECTION ALTERNATIVES SUMMARY TREATMENT METHOD ADVANTAGES DISADVANTAGES A.

Chlorination, a process in which many designers and operators have confidence, could continue to be used as a disinfection process, with the resulting trihalomethanes being removed by some unit process added to the treatment train. The flexibility to permit noncentral treatment to the finished water may also prove to be advantageous. To evaluate one disadvantage of maintaining chlorination practice and treating the trihalomethanes formed, the behavior of the other disinfection byproducts formed during disinfection with free chlorine must be understood. Recall that the reaction of free chlorine and precursors is: Precursors Other Free + (Humic Substances) = Trihalomethanes + Halogenated and Nonhalogenated Chlorine and Bromide Oxidized Byproducts As indicated by this reaction during free chlorination, other halogenated byproducts result. Most of these byproducts cannot be measured individually by gas chromatographic techniques, but they can be estimated as a group, as "organic halogen" (OX). Although not perfect, this test is useful for evaluating the behavior of nontrihalomethane halogenated byproducts during any proposed treatment scheme. Although the health significance of these halogenated byproducts has not been fully evaluated, these byproducts are worth consideration for treatment and removal in light of the changing regulatory attitudes concerning such compounds and the present concerns that have been expressed by the regulatory agencies concerning similar compounds such as THM's. The disadvantage of a treatment approach with the objective of removing trihalomethanes after formation is that other disinfection byproducts may not be removed by the treatment process. Although the concentration of these compounds is not now subject to regulation, minimizing their concentration, where possible, may be the most prudent approach. Furthermore, because chlorine is an oxidant, the possibility of producing oxidation byproducts during chlorination also exists. At the present time, few of these oxidation byproducts can be measured, but their toxicological significance is currently being evaluated. The formation of trihalomethanes is not instantaneous, their concentrations increase as a function of time as the water flows to the consumer.

Proposal EXPENDITURE AMOUNT APPROPRIATION REQUIRED: $6,500 BUDGETED: REQUIRED: $6,500 (Authorized use of bond proceeds) SUHMARY STATEMENT During the Chapter 180 Public Hearing held for the purpose of acquiring the General Development Utility water and sewer system, the City publicly committed itself to implementing a trihalomethane (THM) control system at the Filbert Street water treatment plant once the City owned the system. The Official Statement for the Utilities revenue bonds for the acquisition identified the "TTHM Control System" as a high priority project. Although it is not required by law, implementation of the control system is nevertheless in the best interest of the public to alleviate public concerns about the possibility of carcinogens in the City's newly acquired water system. .. I- requested a proposal from Hal Schmidt of Hartman & Associates, Inc. for the design, permit, inspection, certification, and preparation of record drawings for installation of the ammoniation system. Hal Schmidt's proposal in the amount of $6,500.00 is attached to this request. The construction portion of the project will be let for bids once the design and permitting is completed. The entire project shall be funded from the revenue bond proceeds.

Utilities Director City of Sebastian 1225 Main Street Sebastian, Florida 32958 Subject: Ammoniation System Design - Trihalomethane Control System for Water Treatment Plant Dear Mr. Votapka: This letter constitutes our engineering proposal to design, permit, inspect, certify and prepare record drawings for the installation of an ammoniation system at the City's Filbert Street Water Treatment Plant (WT?) for the purpose of trihalomethane control. The ammoniation feed system will quench the trihalomethane formation reaction and limit the formation potential of the compound in the drinking water. The cost for survey of the site for which the improvements are estimated to be placed is $650. Preparation of the final design drawings and specifications and shop drawing review on behalf of the City is estimated to cost approximately $4,500. The cost for the preparation of the permit application is $500. The cost of one (1) day of inspection, preparation of record drawings and certification to FDEP is $850. It is our understanding that the City would conduct day -today inspections of .the construction. Therefore, no costs for monthly site visits, construction meetings and other miscellaneous meetings will be included in the estimated cost of the project. The total survey, engineering, permitting and technical services cost for this assignment through completion and record drawings is $6,500. The project schedule would be to have the design complete within one (1) month of notice to proceed; permitting complete within three (3) months thereafter; and construction complete within seven (7) months thereafter: � 1+34-7 = 11 Er+.., i In addition, our General Provisions for design, bidding and construction services are provided in Attachment "A" and made a part of this Agreement.

Subject: Ammoniation System Design - Trihalomethane Control System for Water Treatment Plant Dear Mr. Votapka: This letter constitutes our engineering proposal to design, permit, inspect, certify and prepare record drawings for the installation of an ammoniation system at the City's Filbert Street Water Treatment Plant (WTP) for the purpose of trihalomethane control. The ammoniation feed system will quench the trihalomethane formation reaction and limit the formation potential of the compound in the ddnidng water. The cost for survey of the site for which the improvements are estimated to be placed is $650. Preparation of the final design drawings and specifications and shop drawing review on behalf of the City is estimated to cost approximately $4,500. The cost for the preparation of the permit application is $500. The cost of one (1) day of inspection, preparation of record drawings and certification to FDEP is $850. It is our understanding that the City would conduct day-to-day inspections of the construction. Therefore, no costs for monthly site visits, construction meetings and other miscellaneous meetings will be included in the estimated cost of the project. The total survey, engineering, permitting and technical services cost for this assignment through completion and record drawings is $6,500. The project schedule would be to have the design complete within one (1) month of notice to proceed; permitting complete within three (3) months thereafter; and construction complete within seven (7) months thereafter. In addition, our General Provisions for design, bidding and construction services are provided in Attachment "A" and made a part of this Agreement. 201 EAST PINE STREET • surrE 1000 • ORLANDO, FL 32801 TELEPHONE (407) 839-3955 .

Proposal EXPENDITURE AMOUNT APPROPRIATION REQUIRED: $6,500 BUDGETED: REQUIRED: $6,500 (Authorized use of bond proceeds) SUMMARY STATEMENT During the Chapter 180 Public Hearing held for the purpose of acquiring the General Development Utility water and sewer system, the City publicly committed itself to implementing a trihalomethane (THM) control system at the Filbert Street water treatment plant once the City owned the system. The Official Statement for the Utilities revenue bonds for the acquisition identified the "TTHM Control System" as a high priority project. Although it is not required by law, implementation of the control system is nevertheless in the best interest of the public to alleviate public concerns about the possibility of carcinogens in the City's newly acquired water system. I requested a proposal from Hal Schmidt of Hartman & Associates, Inc. for the design, permit, inspection, certification, and preparation of record drawings for installation of the ammoniation system. Hal Schmidt's proposal in the amount of $6,500.00 is attached to this request. The construction portion of the project will be let for bids once the design and permitting is completed. The entire project shall be funded from the revenue bond proceeds. RECOMMENDED ACTION Move that the City Council appropriate the funds in the amount of $6,500.00 and approve the Hartman & Associates proposal to provide engineering services for the trihalomethane control system.

Utilities Director City of Sebastian 1225 Main Street Sebastian, Florida 32958 Subject: Ammoniation System Design - Trihalomethane Control System for Water Treatment Plant Dear Mr. Votapka: This letter constitutes our engineering proposal to design, permit, inspect, certify and prepare record drawings for the installation of an ammoniation system at the City's Filbert Street Water Treatment Plant (WTP) for the purpose of trihalomethane control. The ammoniation feed system will quench the trihalomethane formation reaction and limit the formation potential of the compound in the drinldng water. The cost for survey of the site for which the improvements are estimated to be placed is $650. Preparation of the final design drawings and specifications and shop drawing review on behalf of the City is estimated to cost approximately $4,500. The cost for the preparation of the permit application is $500. The cost of one (1) day of inspection, preparation of record drawings and certification to FDEP is $850. It is our understanding that the City would conduct day-to-day inspections of the construction. Therefore, no costs for monthly site visits, construction meetings and other miscellaneous meetings will be included in the estimated cost of the project. The total survey, engineering, permitting and technical services cost for this assignment through completion and record drawings is $6,500. The project schedule would be to have the design complete within one (1) month of notice to proceed; permitting complete within three (3) months thereafter; and construction complete within seven (7) months thereafter. In addition, our General Provisions for design, bidding and construction services are provided in Attachment "A" and made a part of this Agreement. 201 EAST PINE STREET • SUITE 1000 • ORLANDO, FL 32801 TELEPHONE (407) 839-3955 - FAX (407) 839-3790 ORLANDO FORT MYERS JACKSONVILLE TALLAHASSEE Mr. Richard B.

Box 780127 Sebastian, Florida 32978-0127 Subject: Ammoniation System Design - Trihalomethane Control System for Water Treatment Plant Dear Mr. Votapka: This letter constitutes our engineering proposal to design, permit, inspect, certify and prepare record drawings for the installation of an ammoniation system at the General Development Utilities, Inc. (GDU) Filbert Street Water Treatment Plant (WTP) for the purpose of trihalomethane control. The ammoniation feed system will quench the trihalomethane formation reaction and limit the formation potential of the compound in the drinldng water. The cost for survey of the site for which the improvements are to be placed is $650. The final design drawings and specifications will be prepared on behalf of the City at a cost of $7,500. The cost for the permit fee to the Florida Department of Environmental Regulation (FDER) is $4,000, and the preparation of the permit application is $500, for a total of $4,500. The cost of the day of inspection, preparation of record drawings and certification to FDER is $850. The cost of the preparation and coordination with the ammonia supplier and rental agreement with the ammonia supplier for facilities located at the WTP site to be provided by the, ammonia supplier is $1,000. The total survey, engineering, permitting and technical services cost for this assignment through completion and record drawings is $14,500. 201 EAST PINE STREET • SUITE 1000 • ORLANDO, PL 32801 TELEPHONE HO-) 839-3955 • FAX (407) 839-3-90 PRINCIPALS: JAMES E.

(1-800- 327-9761) SUBJECT: Cost of Regal Chlorinator Automatic Switchover RESUME OF CONVERSATION: I told Rod that eventually our water treatment plant would need an automatic chlorine switchover which it currently does not have (see attached sketch). We have a Regal chlorine regulator made by Chlorinator, Inc. at the present which is affixed to the head of the chlorine tank. Rod said that the chlorine switchover Module would be Model No. A-501. It would cost (list price) $1,486.00. The rate valve needed would cost $320.00, for a total of $1,806. Also, we would have to gut the rate regulator on the existing head for $61.00 and install seat plugs. Rod suggested an entirely new package to replace the existing head at $2304. This would be Model No. 5404. He said an alarm would be needed at $550 for low chlorine levels. This is a new DER rule. Rod said to contact Ed Shiver of Locke Well & Pump Co. in Orlando at 407-299-8888. Normally, a 20% discount is given to customers off of the list price. $2,304.00 for new package OR $1,806.00 $ 550.00 for alarm 61.00 TOTAL $2,854.00 550.00 - 570.00 less 20% discount TOTAL $2,417.00 TOTAL $2,384.00 - 483.00 less 20% TOTAL $1,933.00 ORIGINATED BY: COPY TO: gateI / Vacuum Tubing I I i.

I Chlorine t Ejector/Check Valve Chlorine Solution , ' Cylinder k2 Diffused 3 TYPICAL INSTALLATION AND DIMENSION The Model 225 Vacuum Operated Automatic Switchover Chlorina- tor shall consist of the following components: Two (2) vacuum regulators for mounting directly on chlorine gas cylinder valves (or onto auxilliary header valve of a wall manifold), one (1) vacuum operated switchover module, one (1) chlorine gas flow meter panel with rate valve, and one (1) ejectorlcheck valve assembly. The vacuum regulators shall mount directly onto the cylinder valve by means of a positive yoke type clamp having an integral tighten- ing screw with slide bar handle. The main vacuum regulating dia- phragms shall have a minimum operating area of 13 sq. inches each in order to achieve required accuracy and repeatability of the set chlorine flow rate. All metallic bolts shall mate with metallic threaded nuts or inserts. Plastic mating threads for metallic bolts shall not be acceptable. The switchover module shall be vacuum operated and shall be supplied factory pre-set without any need for field adjustment. The switchover module shall automatically change chlorine feed from an empty chlorine cylinder to a full cylinder, with no manual reset- ting required after switchover has been made and the empty cylin- der is replaced. Vacuum shall be created by an ejector assembly connected directly to the chlorine solution diffuser. The assembly shall consist of a single piece venturi-recovery throat to prevent misalignment, and a back flow check valve to prevent water from entering the gas sys- tem. The check valve shall be of positive, tight shut-off, unitized design not requiring springs or diaphragms for tight closing. Water Supply assembly can be shipped to the factory for overhaul and retest to like new condition for a reasonable, single service charge. It will be re -shipped within 24 hrs. If the unit cannot be taken out of service, we will send an "exchange" unit. ACCESSORIES: Standard (included with chlorinator) 2 -Cylinder Mtd.
