Utilities_Consumer Confidence Report_2006L861 # llWd3d ~d `H~H38 WIVd 1S3M alVd 3~Jd1SOd S'fl aFib'ONb'1S a31dOS3ad 2006 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 rated at 2.73 MGD. The second source is the Reverse Osmosis Water Plant, rated at 1.2 MGD being supplied by two deep wells within the Floridian Aquifer. The third source of supply is water purchased from the Town of Jupiter at the rate of 1.35 MGD. This water is furnished under a bulk water agreement which will expire in the year 2007. As of December 2006, the water system serviced a total of 4,906 water service connections within the Village's service area. The Florida Department of Environmental Protection has made a source water assessment of pontential sources of contamination in the vicinity of the Village of Tequesta public water system wells. The assessment results are available to the public at: www.dep.state.fl.us/swapp. How does the the Utilities Department manage and operate the water system'? The Village of Tequesta Utilities Department operates and maintains its water treatment facilities and 72 miles of distribution system piping. The Utilities Department is operated 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 storage), distribution and customer service. The Utilities Department consists of fourteen employees of which five are licensed water plant operators. How does the eater Treatment Plant treat our drinking water? The Filtration Water Treatment P I a n t receives its raw water from ten surficial aquifer wells that pump water to the Plant. The Plant physically and chemically treats the well water 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 down into the Floridian Aquifer. The water treatment process includes oxidation, coagulation, filtration, and disin- fection by chloramination. The Utilities Department provides a high quality water by using the best avail- able water treatment technologies. Is this all that the Village tests? To assure the safety and reliability of our drinking water, several hundred samples per year are analyzed from the Water Treatment Plant and distribution piping system. The samples are collected and analyzed by certified operators and certified independent laboratories. All of the analytical results from the collected samples are forwarded to the »;~ F l o r i d a Department of Health Services on a monthly basis. Out of all the contaminants that were monitored in our water, 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. How safe, is our water: The Environmental Protection Agency (EPA) has established levels for substances that may be found in the Village's tap water and requires that we communicate this 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 nec- essarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling: ENVIRONMENTAL PROTECTION AGENCY SAFE DRINKING WATER HOTLINE (800-426-479 I ) The Village of Tequesta welcomes your questions and ideas. If you would like to find out more about your Water Treatment Plant, contact us at 561-575-6235. Is the Utilities Department committed to providing the best level of service? This report reflects the effort and dedication of the Village of Tequesta Utilities Department personnel to communicate the results of all testing conducted in our Water Treatment Plant and water system. Our goal is to continue to provide a safe and depend- able water supply for you, our customers. If you have questions or comments, please contact Roy Fallon, Chief Operator, 561- 575-6235.

HOW do 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 through the ground, it dissolves naturally occurring minerals and can pick up substances resulting from the presence of animals or from human activity. Contaminants that mad be pr~•s~•nl iu ra~ti wafer inclade: Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, and wildlife. Inorganic contaminants, such as salts and metals, which are naturally occurring or result from urban storm runoff, industrial or domestic wastewater discharges. Pesticides and herbicides, which may come from a variety of sources such as urban stormwater runoff, and residential uses. Organic chemicals, which are by-products from industrial processes, gas stations, urban stormwater runoff, and septic systems. Radioactive contaminants, which are naturally occurring in some groundwater. Trihalomethanes (TTMs). Some people who drink water containing trihalomethanes in excess of the EPA limits over many years may expe- rience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provid- ed by public water systems. Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled 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 microbial con- taminants are available from the Safe Drinking Water Hotline (800-426-4791).

VILLAGE COUNCIL: James Humpage, Mayor Tom Paterno, Vice Mayor Geraldine A. Genco, Council Member Pat Watkins, Council Member VILLAGE STAFI': Michael R. Couzzo, Jr., Village Manager Roy Fallon, Chief Operator What is the history of our Water System? he original water system was developed by the Jupiter Water Company in 1954 to serve Jupiter Inlet Colony. This water system included two surficial aquifer wells, a 1.00 million gallon per day (MGD) aeration/filtration/chlorination pumping station and a 60,000 gall~~ elevated storage tank located just south of Bridge Road. By 1957, the system was expanded to serve neighboring subdivi- sionsand portions of the Vill 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 aquifer wells and a treatment facility at 901 N. Old Dixie Highway. This construction increased the Water Treatment 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 treatment -'- -t capacity to 2.73 MGD. In 1998, the Village initiated its latest phase of expan- sion to the Water Treatment Plant. This led the construction of a "state-of-the-art" reverse osmosis water treat- ment facility, with an ultimate capacity of 3.6 MGD, initially sized for 1.2 MGD. The $7.8 million expansion project was funded through a bond issue. The reverse osmosis water treatment facility became fully opera- tional in March 2000.
