TRS pe ; TOWN OF PALM BEACH MEMORANDUM TO: Paul Brazil, Director of Public Works FROM: James M. Bowser, Town Engineer HD RE: Private Irrigation Water Supply Systems DATE: January 22, 2009 Town staff was asked to look into what it would cost for a "typical" Palm Beach homeowner to construct their own independent irrigation water supply system. This is not an easy question and would take a fairly detailed analysis from one of our water consultants that time and funding has not permitted. Town staff has had several discussions with our consultants and the results of these discussions revealed the following. - A 12 acre site in Manalapan constructed its' own water supply system using Floridan Aquifer, total price, between $400,000 and $450,000. - Floridan water well permits for individual owners are possible, but wells cost hundreds of thousands of dollars to construct due to the 1200 to 1400 foot depths. These wells are not necessarily drought proof. - Shallow salt water wells are possible and would provide a water supply that would not have restrictions. Dig too shallow, and the water will be aerobic and hydrogen sulfide is present, requiring a chlorination system. Dig deeper, you would get to an anaerobic zone that avoids the hydrogen sulfide. These salt water aquifers will require a higher degree of treatment, costing more than a Floridan source. - Treatment facilities will need to be sized to irrigation demand. To minimize treatment capacity, storage is needed. A pressurized system will need to be built. If requested, several scenario's can be developed and priced. - Electrical service and treatment facility housing needs will be tailored to the system design. - Ballpark, the cheapest systems will likely exceed $100,000 with ongoing operation and maintenance costs, c.

Note that the City of NY produces about 33 times the amount of water than the City of West Palm Beach. We tried to compile data that can be comparable. However, NYC act as their own State agency and track different parameters than the State of Florida. See below for additional information. Eduardo E. Balbis, P.E.

NCY produces 1.1 billion mgd per day. Below is what they say about their treatment process: Water Treatment All surface water and groundwater entering New York City’s distribution system is treated with chlorine, fluoride, food grade phosphoric acid and, in some cases, sodium hydroxide. New York City uses chlorine to meet the New York State Sanitary Code and federal Safe Drinking Water Act (SDWA) disinfection requirements. Fluoride, at a concentration of one part per million, is added to help prevent tooth decay and has been added since 1966 in accordance with the New York City Health Code. Phosphoric acid 1s added to create a protective film on pipes that reduces the release of metals such as lead from household plumbing. Sodium hydroxide is added to Catskill/Delaware water to raise the pH and reduce corrosivity.

ull Page 1 of 8 EXECUTIVE SUMMARY Recent Drinking Water Testing Completed and the Results The City of West Palm Beach (City) treats surface waters at their downtown facility and produces drinking water for the residents of West Palm Beach. Residents of the Town of Palm Beach (Town) receive potable water from the City through a franchise agreement that expires in the year 2029. Due, in part, to the highly publicized " precautionary boil water" notice issued by the City in September of 2007, concerns arose regarding the overall safety of the drinking water supply being provided to the Town. Accordingly, HSA Engineers and Scientists was asked to collect and analyze additional samples from the water supply. These additional samples were collected by HSA personnel on November 14, 2008 and were submitted to a laboratory independent of the ones used by the City for their routine drinking water testing requirements mandated by the U.S. Environmental Protection Agency (USEPA) and the Florida Department of Environmental Protection (FDEP). There are more than 90 testing parameters that are required to be analyzed on drinking water supplies by the USEPA and the FDEP. HSA collected samples and tested for all of these drinking water parameters and the detailed results are supplied in the enclosed tabular summary. Also as shown in the attached detailed summary table, all of the testing results obtained from our recent sampling passed and all constituents were well below the allowable limits established by State and Federal regulations. What are Trihalomethanes (THMs) and Why Did We Receive a Notice That They Were Elevated? During the precautionary boil water notice that occurred during the latter part of 2007, the City added more chlorine to their finished drinking water to ensure adequate bacterial kill. Chlorine reacts with natural organics (that cause variations in the water’s color) producing a group of compounds called Trihalomethanes (THMs). Up to a point, the higher the chlorine dose added, the higher the THM concentrations produced. The USEPA has established a limit of 80 parts per billion (ppb) for drinking water supplies. In a few samples collected by the City during the ‘boil water notice’ time period, elevated THM test results were obtained due to the additional chlorine in the drinking water. This represented a one-time spike in THM results and the current level is well below the 80 parts per billion limit. During the special testing completed by HSA, the THM level was measured at slightly more than 50 parts per billion, well below the acceptable limit set by the regulators. HOUSE_OVERSIGHT_016681

ull Page 2 of 8 What Do | Need To Do To Ensure My Drinking Water is Safe? Aside from the recent test results collected and analyzed by HSA, we reviewed historical test results, also summarized in the enclosed table. The City produces a safe drinking water of high quality based on the test results over the last several years. According to the USEPA and the FDEP established standards, the City’s drinking water supply is of good quality and can be consumed directly without concern. For those who want an added measure of protection, substituting bottled drinking water is an option or under the kitchen counter reverse osmosis (RO) filtration system can be installed as added intermediary treatment to provide an excellent source of high quality of drinking water. These RO units are not cost prohibitive, can be easily installed, and can usually supply sufficient drinking water for a typical household. A separate tap is usually installed near the standard sink faucet so the RO water is delivered on demand. There are several local reputable vendors that can provide free quotation for installing under the kitchen counter RO units. Please note that the typical RO unit we are referring to does not treat the entire household water supply but rather just the water intended for drinking or cooking purposes. To add a layer of confidence to residents’ concerns about the quality of the City’s drinking water, we also recommend that the Town establish a primary point of contact for the City for courtesy notification and/or discussion of real time details related to issues with the City’s treatment and distribution processes. This could potentially avoid dramatized response to typically less-detailed public notification. INTRODUCTION Residents of Palm Beach receive potable water from the City of West Palm Beach (City) through a franchise agreement Town of Palm Beach (Town). As required under rule 62-550, Florida Administrative Code, to protect the public health and ensure the quality of the delivered potable water product, these taps are routinely sampled by the City of West Palm Beach’s Public Utilities Department for specified monitoring parameters. Concerned about assuring the quality of the potable water product delivered to Town residents by the City, the Town authorized HSA Engineers & Scientists (HSA) to conduct a one-time sampling event from two of the sampling taps on the potable water distribution system (piping) serving the Town. Collected samples were targeted for laboratory analyses for regulated water chemistry parameters, constituents, and microbiologics most likely to be present in South Florida drinking water supplies.

ull Page 3 of 8 CITY OF WEST PALM BEACH’S DRINKING WATER MONITORING PROGRAMS HSA evaluated the City’s monitoring program and most recent results. Steve Schmidt, laboratory manager at the City’s water treatment plant and Chris Saliba of U.S. Water, Corporation, the City’s treatment system process and monitoring consultant, assisted with the acquisition of sampling protocols and laboratory analytical documentation related to the City’s drinking water monitoring program. Discussions with both yielded important information about the City’s drinking water monitoring and quality assurance programs. In addition, records of the City’s Monthly Operating Records (MORs) and recent results from the City’s water monitoring programs were obtained from the Palm Beach County Health Department (part of the State of Florida’s Department of Health, FDOH). The City conducts two programs to monitor its drinking water quality, a Compliance Monitoring Program (compliance) and a Routine Monitoring Program (routine). Sampling locations for the City’s two monitoring programs include the surface water impoundments, inbound raw water, aquifer storage and recovery (ASR) wells, treatment plant points of entry, distribution system points of entry, and distribution system pumps and sampling taps. While Routine program sampling events generally range from monthly to “as needed”, compliance program sampling events generally range from daily to quarterly to annually to sampling for contaminants (like asbestos) every ninth year. To monitor the drinking water quality delivered to the Town, the City conducts routine sampling at ten (10) permanent and temporary compliance distribution system sampling points (taps) situated within the Town’s boundaries. These include: e Distribution System Tap 3230 (located at 3230 S. Ocean Dr.); e Distribution System Tap 2780 (located at 2780 S. Ocean Dr.); e Distribution System Tap PBGC (located at the Palm Beach Golf Course); e Distribution System Tap SOFS (located at the South Fire Station); e Distribution System Tap ISRD (located at Island Rd.); e Distribution System Tap RPBR (located at Royal Poinciana Blvd. X Bradley PI.); e Distribution System Tap NOFS (located at the North Fire Station); e Distribution System Tap 702 (located at 702 N. County Rd.); e Distribution System Tap LINL (located at List Rd. X N. Lake Wy.); and e Distribution System Tap IDSE #6 (located at the north end of Ocean Blvd.); HOUSE_OVERSIGHT_016683

ull Page 4 of 8 An eleventh distribution system tap, 4201, is located at 4201 South Ocean Boulevard (in the South Palm Beach municipality), outside the jurisdiction of the Town. The Phipps Park “Booster’ Pumping Station (PS) is located within the Town’s jurisdiction. The Phipps Park “Booster” is not a point of entry (POE) to the Town’s distribution system. The City’s map indicates the locations of the sampling taps, the booster pump station, and a one million gallon (1 MG) storage tank within the Town’s jurisdiction. Figure 1 depicts the distribution system sampling taps, “booster” pumping station, and storage tank located within the Town’s boundary. The City conducts annual compliance sampling at several sampling locations, most notably from the first point of entry (POE) to the distribution system. According to the City’s Water Treatment Plant laboratory manager, the first POE is the tap located in the Water Treatment Plant’s analytical laboratory. POINTS OF ENTRY FOR THE CITY’S DELIVERY OF DRINKING WATER TO THE TOWN Plans of the distribution system serving the Town, provided by the Town’s Public Works Department (PWD), identified five potable water transmission mains (large diameter pipes) crossing the Intracoastal Waterway and connecting to the distribution system to deliver the City’s potable water product to the Town. These five pipes include: e A 24-inch diameter transmission main crossing the Intracoastal Waterway (ICW) from/to 5th Street (in the City) to the eastern flank of the Royal Poinciana Bridge (in the Town): e A 16-inch diameter water main crossing the ICW from/to 45" Street (in the City) to the intersection of North Lake Way and Orange Grove Road (in the Town); e A 16-inch diameter water main crossing the ICW from the southern end of Flagler Drive (in the City) to the west end of “Sloan’s Curve (on State Road A1A, in the Town); e A 16-inch diameter water main crossing the ICW from the intersection of Southern Boulevard with Flagler Drive (in the City) to the eastern flank of the Southern Boulevard Bridge (in the Town); and e A 20-inch main crossing the ICW from the City to Everglades Island, near Barcelona Avenue (in the Town). HOUSE_OVERSIGHT_016684

ull Page 5 of 8 Figure 1 also depicts the approximate ICW crossings and points of entry (POEs) of the transmission mains to the Town. The scale of the map does not allow an accurate depiction of the POEs associated with the mains. Maps of the Town’s distribution system provided by the PWD, generated at a significantly larger scale, were used to reference the locations of the POEs for the transmission mains. SAMPLING AND ANALYSIS OF THE DRINKING WATER PRODUCT DELIVERED TO THE TOWN As a means to independently evaluate the quality of the drinking water being delivered to the Town, on November 14, 2008 HSA, accompanied by an employee of the City’s Public Utilities Department, sampled distribution system tap IDSE #6, representing the northern-most extent of the system, and tap 3230, representing the southern-most extent of the system,. Figure 1 depicts these sampling tap locations. Sampling was performed by modification of the City’s (distribution system) General Sampling Procedures to reflect the intended exclusion of sampling equipment, field parameter testing, associated equipment calibration requirements. Samples were collected in laboratory- supplied, unpreserved and pre-preserved containers. As required by select analytical methodologies, at the sampling locations preservative was added to those sample containers immediately prior to filling or to the water sample immediately prior to sealing the sample container. Collected water samples were submitted to FDOH/NELAC-certified testing laboratories for analysis for typical public potable water system routine and compliance monitoring parameters including Primary Drinking Water Standards (excluding select Disinfection Byproducts, Haloacetic Acids; Bromite; and Chlorite), for Secondary Drinking Water Standards, and for Total Coliform as listed in the Florida Administrative Code rule 62-550. Test America Laboratories performed all of the analyses for chemical parameters. Jupiter Environmental Laboratories performed the analyses for the microbiologics. RESULTS FROM INDEPENDENT ANALYSIS OF THE CITY’S DRINKING WATER PRODUCT Results of laboratory analysis for target Primary and Secondary Drinking Standards yielded all chemical and physical parameters below method detection limits (MDLs) or less than respective maximum contaminant limits (MCLs). Results of laboratory analysis for target microbiologicals yielded an absence of Total Coliform in the water samples collected from northern-most Tap A (IDSE #6) and southern-most HOUSE_OVERSIGHT_016685

ull Page 6 of 8 Tap B (3230). Table 1 arrays the target Primary and Secondary Drinking Standards, regulated MCLs, required sampling frequency, and laboratory analytical results for the November 14, 2008-collected water samples. Appendix A contains the laboratory analytical reports from HSA’s November 14, 2008 sampling event. COMPARISON TO RECENT CITY MONITORING PROGRAM RESULTS The City’s most recent annual compliance monitoring event for Primary and Secondary Drinking Water Standards was performed in June 2008. The sample of ‘finished’ water product was collected at a sampling point (laboratory tap) at the water treatment plant. Analysis was performed by the City’s FDOH/NELAC-certified, vendor analytical laboratory, Genapure. Analysis yielded all target parameter results below method detection limits (MDLs) or less than respective maximum contaminant limits (MCLs) per Chapter 62-550, F.A.C. The City’s most recent quarterly routine monitoring event for Nitrate and Nitrite was performed in August 2008. The sample of ‘finished’ water product was also collected at the water treatment plant’s laboratory tap. Analysis was again performed by the City’s vendor analytical laboratory, Genapure. The detected concentration of Nitrate was less than the MCL (10 mg/L). The concentration of Nitrite was below the MDL (< 0.053 mg/L). Nitrate concentrations from HSA’s November 2008 sampling event are lower than either result reported from the City’s annual or latest quarterly sampling from the water treatment plant's laboratory tap. The difference between these results is not relevant since the reported concentrations from the City and from HSA’s sampling event are still less than the MCL. Table 1 includes a comparative array of the City’s monitoring program results to the results from HSA’s November 2008 distribution system tap sampling for the target Primary and Secondary Drinking Standards. APPLICATION OF DISINFECTION CHEMICALS, BYPRODUCTS, AND THE EFFECT ON TASTE To eliminate the presence of microbiologics, such as Coliform bacteria, the City applies chlorine at the treatment plant to disinfect the processed supply water. This treatment process results in the formation of chemical compounds in the potable water product known as Disinfection Byproducts (DBPRs). The allowable concentrations of DBPRs in drinking water are set as Standards in FDEP rule 62-550, F.A.C. The latest quarterly (3-month) reporting period for the City’s weekly routine monitoring of DBPRs (Total Trihalomethanes, TTHMs) ended September 2008. The samples of water HOUSE_OVERSIGHT_016686

ull Page 7 of 8 product are regularly collected at a series of distribution system sampling taps. Analysis was performed by the City’s analysts at the Water Treatment Plant’s laboratory. Results from HSA’s sampling of the Town’s drinking water from northern-most Tap A (IDSE #6) are directly compared to the City’s routine sampling of drinking water from distribution system tap LINL (closest to Tap A). Results from HSA’s sampling of the Town’s drinking water from southern- most Tap B (3230) are compared directly to those from the City’s sampling of that tap. TTHM concentrations from HSA’s November 2008 sampling event are slightly higher than the averages of the results reported from the City’s latest quarterly sampling from tap LINL and tap 3230, respectively. The difference between these results is not relevant since the reported concentrations from the City and from HSA’s sampling event are still less than the MCL. It is noted that the concentration of TTHMs reported from the City’s annual compliance event (collected at the Treatment Plant) is close to the MCL. This is not unexpected as the sampling location (treatment plant laboratory tap) is much closer to the point of disinfection than the distribution system sampling taps. Table 1 includes a comparative array of the detected TTHM’s from City’s monitoring program to those detected from HSA’s November 2008 sampling event as well as the TTHM Standards per rule 62-550, F.A.C. The City Public Utilities Department acknowledges that to keep the potable water product free of microbiologics occasionally requires increasing the concentration of disinfecting chlorine added to the supply water. This results in brief incidences of potable water product with a notable change in the taste and higher concentrations of DBPRs. Concentrations of DBPRs and the stronger taste of chlorine subside with the inevitable reduction of chlorination. CONCLUSION As a measure of the quality of the drinking water product being delivered to the Town by the City, results from HSA’s November 2008 collection of potable water from the northern-most and southern-most distribution system sampling taps revealed target regulated drinking water parameters at concentrations below the MCL standards established in FDEP rule 62-770, F.A.C. A comparative of the results obtained from HSA’s sampling event to the City’s reported annual and quarterly results from 2008 monitoring events found minor variations in reported concentrations for select parameters (see Table 1). These variations pose no concern for the quality of the potable water product being delivered to the Town since all parameter concentrations reported from the City’s monitoring events and by HSA’s sampling event are less than respective MCLs. HOUSE_OVERSIGHT_016687

ull Page 8 of 8 Comparison of a three-year average of the concentrations of Primary and Secondary Drinking Water Standards from the City’s annual compliance monitoring events (circa 2006, 2007, and 2008) to the results from HSA’s November 2008 distribution system tap sampling reveals relative equivalence with irrelevant differences between select parameters concentrations since the averaged City results are less than respective MCLs (see Table 1). With the exception of the occasional spike in concentrations of DBPRs (and corresponding stronger taste of chlorine in the delivered drinking water) resulting from the City’s need to increase the application of sanitizing chemicals (i.e. chlorine) to treat supply water, HSA concludes that the quality of the potable water product delivered to the Town by the City meets or beats the criteria for the standards established under rule 62-550, F.A.C.
