Water Plant expansion Completed 2007 © Develop along-range strategic plan to meet future infrastructure and utility sei°vice needs for community growth, development, and expansion. © Enhance public awareness of environmental surroundings. In December of 2006 work was started on the Water Treatment Plant Expansion. Substantial completion of the expansion was done by September 2007. The expansion provides another 12 m.g. to the water plant design capacity to produce water and provides a third R.O. well for source supply. In addition to increasing, water production. the expansion included the conversion of gas chlorine to sodium hypochlorite (liquid). The conversion makes it safer for the Villase of Tequesta residents and the Village Employees by the removal of 10.000 LBS of chlorine gas from the Water Treatment Plant Treauneni Plant site.

This water system included two surficial aquifer wells, a l .00 million gallon per day (MGD) aeration/filtration/ chlorination pumping station and a 60,000 gallon elevat- ed storage tank located just south of Bridge Road. By 1957, the system was expanded to serve neighboring subdivisions and portions of the Village of Tequesta. In 1967, the Village of Tequesta purchased the water system from the Jupiter Water Company for $1,700,000. In 1977, the Village constructed additional surficial aqui- ferwells and a treatment facility at 901 N. Old Dixie Highway. This construction increased the Water Treat- ment Plant's permitted capacity from 1.00 MGD to 1.80 MGD. The Plant facility was expanded again in 1988 by the addition of new wells, chemical feed systems and pressure filters, increasing the overall water treat- ment plant capacity to 2.73 MGD. In ] 998, the Village initiated its latest phase of expansion to the Water Treatment Plant. This included the construction of a "state-of-the-art" reverse osmosis wa- ter treatment facility, with an ultimate capacity of 3.6 MGD, initially sized for 1.2 MGD. The $7.8 million ex- pansion project was funded through a bond issue. The reverse osmosis water treatment facility became fully operational in March 2000. ~~` COQ `' ~ o ~~~--1 n ~t~~ >~ A L CONTAMINANT & UNIT DATES OF MCL (VIOLATION) HIG HEST MONTHL Y MCLG MCL LIKELY SOURCE OF OF MEASUREMENT SAMPLING (mo/yr) Y/N PERCENTAGE/NUMBER I CONTAMINATION Total Coliform Bacteria Monthly N 1 ~ For systemscooeamgfewermanao ---- Naturally present in the 2008 samples per month: presence of colifor m environment bacteria in 1 sample collected during a month RADIOLOGICAL C ONTAMINANTS CONTAMINANT & UNIT DATES OF ;MCL (VIOLATION) LEVEL RANGE OF MCLG MCL LIKELY SOURCE OF OF MEASUREMENT SAMPLING (mo/yr ) Y/N DETECTED RESULTS CONTAMINATION Alpha emitters (pCi/L) 6/08 N 0.7 N/A 0 15 Erosion of natural deposits Radium 226 + 228 or combined radium (PCi/L) ~ 6/08 N ~.. 0.4 N/A _ ; 0 5 Erosion of natural deposits Uranium fug/L) 6/08 N 0.001 N/A 0 30 Erosion of natural deposits INORGANIC CONT AMINANTS - CONTAMINANT & UNIT DATES OF MCL (VIOLATION) LEVEL RANGE OF MCLG MCL LIKELY SOURCE OF OF MEASUREMENT SAMPLING (mo/yr) Y/N DETECTED RESULTS CONTAMINATION Barium (ppm) 6/08 N 0.0115 N/A 2 2 Discharge of drilling wastes: discharge from metal refineries: erosion of natural deposits Erosion of natural deposit: discharge from fertilizer and Florlde (ppm) 6/08 N 0.26 N/A 4 4.0 aluminum factories.

The Environmental Protection Agency (EPA) has established levels for sub- stances that may be found in the Village's tap water and requires that we com- municatethis information to you on an annual basis. The table on the back page also shows these levels as regulated by EPA and the highest levels found in the Village-s water. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a healCh risk. More information about contaminants and potential health effects can be obtained by calling: ENVIRONMENTAL PROTECTION AGENCY SAFE DRINKING WATER HOTLINE (800-426-4791) How do contaminant! ~~t into o , water? The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams. ponds. reservoirs, springs. and wells. As water travels over the surface of the land or throush the eround. it dissolves naturally occurring miner- als and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in raw water include: Microbial contaminants, such as viruses and bacteria, which may come from sewa~ e treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff. industrial or domestic wastewater dischar,es, oil and gas pro- duction, mining, or farming. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. Organic chemicals contaminates, including synthetic and volatile organic chemicals, which are by-products of indus- trial processes and petroleum production, and can also come from eas stations, urban stormwater runoff, and septic sys- tems. Radioactive contaminants, which can be naturally occur- ring or be the result of oil and gas production and mining activities. In order to ensure [hat tap water is safe to drink, EPA perscribe~ regulations which IimiC the amount of .certain contami- ~ Hants in water provided b~ , , z public water systems. Food and Drug Administration (FDA) regulations establish limits for contaminants in bot- tled water which must provide the same protection for public health. Some people may be more vulnerable to contaminants in drinking water than the general population. such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders. Some elderly and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbi- al contaminants are available from the Safe Drinking Water Hotline (800-426-4791). The effects of lead in drinking water on children If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and compo- nents associated with service lines and home plumbing. Village of Tequesta is responsible for providing hieh quality drinking water, but cannot control the variety of materials used in plumbing components. When yom- water has been sittins for several hours, you can minimize the potential for lead exposure by Hushing your Cap for 30 seconds to 2 minutes before using water for drinking or cookinv. If you are concerned about lead in your water, you may wish to have yom• water tested. Infor- mation on lead in drinking water, testing methods. and steps you can take to minimize exposure is available from the Sate Drinking Water Hotline or at http://www.epa.gov/safewatcr/ Where does our water come from? The Village currently has three sources of potable water supply to meet its current needs. The first source is the Filtration Water Treatment Plant, which utilizes ten surficial wells and is sated at 2.73 MGD. The second source is the Reverse Osmosis Water Plant, rated at 2.4 MGD being supplied by three deep wells within the Floridan Aquifer. The third is an emergency water agreement with the Town of Jupiter. As of December 2008, the water system serviced a total of 4,947 water service connections within the Village's service area. How does= the In 2008 The Florida Department of Environmental Protection created a Source Water Assessment & Protection Program (SWAPP) showing potential sources of contamination in the vicinity of [he Village of Tequesta public water system wells. Wilh concerns ranging from hish to low presently there are 12 potential contamination sites of moder- ate concern. The assessment results are available to the public at: www.dep.state.fl.us/swapp. The Village of Tequcsta Utilities Department operates and maintains its water treatment facilities and 72 miles of distribution system piping. The Utilities Department is operat- ed under the supervision of the Village Manager who also serves as the Utilities Director. The Utilities Department has four divisions which include administration. water treatment (pumping and storaee), distribution and customer service. The Utilities Department consists of sixteen employees of which five are licensed water plan[ operators and four who are certified water distribution system operators. The Filtration Water Treatment Plant receives its raw water from ten surficial aquifer wells that pump water to the Plant. The Plant physically and chemically u•eats Che well wa- ter to produce potable water, which meets and exceeds the standards of the Safe Drinking Water Act. The new Reverse Osmosis Water Treatment Plant provides desalination of salty water from one of two wells nearly 1,800 feet downintotheFloridianAquifer. Thewateru-eat- mcnt process includes oxidation, coagulation, filtration, and disinfection by chloramination. The Utilities Departmentprovides a high quality water by using the best available water treat- ment technologies. Is this all that the Village tests? To assure the safety andreliabi I sty of ourdrinki ng water. sev- eral hundred samples per year arc analyzedfrom the Water Treatment Plantanddistributionpsping system. The samples are collected and analyzed by certified operators and certi- fied independent laboratories. All of the analytical results 5-om the collected samples are forwarded to the Florida Deparhnent of Health on a monthly basis. Out of all the contaminants that were monitored in our w°ater, most were not detected. These non-detectable contaminants include organic and inorganic chemicals, natural and synthetic chemical compounds, volatiles, unregulated contaminants, and microbiological organisms. Only the contaminants that were detected are included in the test result table of this Water Quality Report. r p ~ r~ 1d153f1~'l31 ~O 39d171A L861 # 1IW83d l3 'H~V38 Wlb'd 1S3M aldd 39'd1SOd 'S'(1 48d4Nb'1S a3180S3~d 69~~~ "Id `~lsanba~, ani.~a ~~sanbal S~£
