Por favor lea este informe o communiqu6s con alguien que pueda traducir la informacion. We are once again pleased to present to you our annual water quality report. This edition mvers all water quality monitoring through December 31,2023. The Water Services Department is dedicated to producing drinking water that meets or exceeds all state and federal drinking water standards. We continually strive to adopt new and better methods for delivering the best quality drinking water to you. As new challenges to drinking water safety emerge, we remain vigilant in meeting the challenges ofsourcewaterprotection,waterconservation,andcommunityeducationwhilecontinuingloservetheneedsofallourwaterusers. Pleaseshareyourthoughtswithus about the information in this report, as well-informed customers are our best allies. How can I leam more? lf you want to learn more about this report or have questions relating to your drinking water provided by St. George, please call Scott Taylor, Water Services Director or Kerry Benson at (435) 6274800. lf you want to get involved in water resourcs, you can attend any of the regularly scheduled meetings of the Washington County Water Conservancy District (WCWCD). Meetings are held at 533 East Wateruorks Drive (just off East Red Hills Parkway) in St. George. The schedule is available at http://www.wcwcd.org/about- us/managemenUboard-of-trustees-meeting-schedule/ or call (435) 673-3617. Where does my water come from? Our water sources are from both groundwater and surface water sources. Our multiple spring and groundwater sources draw from consolidated rock aquifers of the Navaio Sandstone and Kayenta Formation, which lie within the Virgin River basin. We purchase our surface water from the Washington County Water Conservancy District. Their surface water is drawn from the Virgin River, stored at Quail Lake and Sand Hollow Reservoirs and treated at the Quail Creek Water Treatment Plant before transmission to our Cily boundaries and distribution to our customers. With some exceptions, all water customers within the City receive a mixtureofwaterfromgroundwaterandsurfacewatersourcesduringsomeoftheyear, CustomerslocatedalongStateHighwaylSasfarnorthastheLedgesSubdivision are served by groundwater from our Tolman-Ledges wells and by spring water supplied by a recently completed pipeline and pump slalion. Water Conservation Tip - Repair a dripping faucet and you can save '15 to 20 gallons per day or 6,000 gallons of water each year, Source Proteclion: Drinking Water Source Protection Plans (DWSPPs) for the City of St. George are available for your review. They contain information about source protection zones, potenlial conlamination sources, and management strategies to protect drinking water that originates from City-owned groundwater wells and springs, Most of our groundwater sources are located in remote and protected areas and have a low level of susceptibility to potential contamination sources. We have also developed management stratEies to further protect our sources from contaminalion. Our plans are available for review on the City's web site at www.sgcity.org/utilities/waterdepartment or during normal business hours from the St. George Water Department office located at 811 East Red Hills Parkway, Please contact us if you have questions or @ncerns about our source protection plan. The WCWCD maintains the Watershed Protection Plans for the portion of the Virgin River basin from which they draw, store and treat surface water. Additional information on their source protection plans can be obtained by calling (435) 673-3617. Ulater Conservation Tip - Check toilets for leaks by putting a few drops of food coloring in the rear tank, Check the bowl after a few minutes to see if the color appears. lf it does, you can easily repair the leak and save up to 30,000 gallons of water per year, Water Hardness: Most of the water sources in Southern Utah are said to be "hard'and that's because they contain high amounts of non{oxic calcium or magnesium minerals, Hard water does not dissolve soap readily, so making lather for washing and cleaning is difficult. Many customers use treatment devices, such as water softeners, to remove the calcium and magnesium from tap water to produce soft water for household use, Customers with water softeners may find that softener settings between 13 to 2l gnins per gallonwill provide the most effective treatment. irufi(.qIfiIM]EU CITY OF ST.

Unless othenvise noted, the following table lists all drinking water contaminants that we detected in our water through analytical monitoring during the 2023 calendar year, or during the last sample event. You may find terms and abbreviations in the table below that you may not be familiar with. We have provided definitions below. When reviewing this table, please recognize that all sources of drinking water are subject to potential contamination by constituents that are naturally occurring or man- made. Those constituents can be microbes, organic or inorganic chemicals, or radioactive materials. All 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 the water poses a health risk. To ensure that tap water is safe to drink, EPA imposes regulations that limit the quantity of certain contaminants in water provided by public water systems. Please note that all contaminants listed in this table were found to be present in concentrations below the maximum contaminant levels established by EPA. The EPA has determined that your water lS SAFE at these levels. More information about contaminants and potential health effects may be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at 1-8m426-4791. lnit of Measure oescri )tions ppb PartsperBillion-Thenumberofpartsofa$ubstanceinonebillionpartsofwater.

MNR ilonitored l,lot Regulaled IllPL llaximum Pemissible Level - State assigned Substances That Could Be in Water: Sources of drirking water (both bottled and tap) include rivers, lakes, streams, ponds, reservoi's, springs and wells, As water travels over the surface of the land or though the ground, it can dissolve naturally occurring materials, and can pick up a wide variety of substances: c Microbial Contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultur;rl livestock operations, or wildlife, o lnorganic Contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial, or domestic wastewater discharges, oil and gas production, minirg or farming, o Pesficldes and Herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses, o Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and which may also come from urban stormwater runoff, gas stations and septic systems. o Radioactive Contaminants, which can be naturally occurring or may be the result of oil and gas production and mining activities. o More information about contaminants and potential health effects can be obtained by calling the U.S. EPA's Safe Drinking Water Hotline at (800) 426- 4791, or their web site at: www.eoa.qov/qround-water-and-drinkino- waterlsafe-d rin kino-water-information Water Conservation Tip - lrrigate during the evening, night or early morning hours to reduce water lost to evaporation. D rinkino Water Terms & Acronvms Arsenic: Some individual water sources in our system have arsenic concentrations that exceed 10 ppb. The City meets the MCL by combining sources to blend water or by treating the source water 1:o remove arsenic so that the water delivered to customers does not exceed the EPA standard. All water delivered to customers in 2023 met the EPA standard f,rr arsenic concentrations not exceeding 10 ppb running annual average. Our blending treatment proposals were approved by the Utah Division of Drinking Water & detailed performance testing concluded in 201 1. The City was able to demonstrate that our blending treatment proc€tss can meet the arsenic MCL for our affected sources. ln 2021, the City of St. George completed construction of an arsenic removal plant which is now reducing the arsenic concentration n water produced by our Gunlock well sources. Also, in 2021, lhe Washington County Water Conservancy District placed a similar plant into service that is now removing arsenic from the District's Sand Hollow Well sources. Some people who drink water containing arsenic that is in excess of the MCL over many years could experience skin damage or problems with their circulatory system and may have an increased cancerr risk. lt is important to note that EPA's arsenic MCL balances the current understanding of arsenic's possible health effects against the costs of removing arsenic from drinking water. EPA continues to research the health effects of chron c exposure to low levels of arsenic (see table for arsenic levels). Poinlof-use treatment devices (i.e., reverse osmosis or distillation) can be effective in removing arsenic, However, their effectiveness varies, they can be expensive, and they must be properly maintained. Customers who choose to install water treatment devices are advised to monitor system performance with routine testing and ensure the system is maintained ias recommended by the manufacturer. Health lnfo on Microbiological Contaminants: Sorne people may be more vulnerable to microbiological contaminants in drinkingl water than the general population. lmmuno-compromised persons such as persons wilh cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be paflcularly at risk from infections, These people should seek advice about drinking water from their health carer providers. EPAJCDC guidelines on appropriate means to lessen the risk of infection by miuobiological contaminants are available from the EPA's Safe Drinking Water Hotline (800- 426-4791). ln Home Filtration Systems: Customers are advised to exercise caution with whole-house filtration systems that remove the chloriner used by our water utility for water disinfection. By unknowingly removing the residual chlorine con<;entration in your home piping network, you could allow microbes to multiply in the home piping. These microbes may cause illnesses, especially for immuno-compromised family members, These types of filters are best limited to point of use such as the kitchen faucet. Fluoride: The fluoride present in our drinking water is f'om natural deposits. St. George City does not add fluoride to our water (see table for fluoride concentrations). Answer to Common Concern: Growths in bathroorns or pet bowls that are pink or black in color come from various types of moldt; in the air - not your tap water. Wash those surfaces frequently and keep fresh water in pet bowls. Lead: lf 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 components associated with service lines and home plumbing. We are responsible for providing high quality drinking water but cannot control the variety of materials used in plumbing components. All customers can minimize their potential for exposure to lead by flushing faucets for 30 seconds to 2 minutes before using the water for drinking or cooking, lnformation on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at www.epa.gov/safewater/lead. The age of your home is an indicator of what type of plumbing materials you may have. Homes built prior to the early 1900s commonly used lead pipes for plumbing. Until the 1940s, lead piping was often used for the service lines connecting meters tothewatermains, ln the 1950s, copperorgalvanized piping replaced lead piping in many homes. Until the mid-'1980s, copper piping was installed with solder and fluxes containing lead, lf your home fits any of these categories, your plumbing may mntain lead that can leach into your drinking water, especially when it has nol been used for several hours (see table for lead levels). Cross-connections: Cross-connections to drinking water system lines are a major concern. A cross-connection is formed at any point where a drinking water line connects to equipment containing chemicals, or water sources of questionable quality. Examples are boilers, air conditioning systems, fire sprinkler systems, inigation systems, etc, Whenever equipment pressure rises above the pressure in the drinking water system line, contamination can occur. Backpressure from the equipment allows contamination to pass into the drinking water line, Contamination by backsiphonage occurs when the pressure in the drinking water line drops below that outside of the pipe or in connected equipment. This can happen under normal operating scenarios when demand is heavy, or when a main breaks. Backsiphonage draws contaminants out of sunounding soil and water or connected equipment & into the drinking water line, City Ordinance Section 8-2-4, A requires the following from property owners: "... lt shall be the responsibility of the owner of property where water is consumed to purchase, install, test, inspect and maintain bacKlow prevention devices or assemblies wherever it will be possible for used, unclean, polluted or contaminated water, mixtures or substances to enter any portion of his potable water system, and to otherwise mntrol cross-connections.' Customers must protect water supplies from cross-connections by identifying cross-connections and installing & maintaining proper backflow prevention assemblies, Exterior water faucets tend to be the most common sources of cross-connection contamination. All exterior faucets should be equipped with hose brb vacuum breakers to provide backsiphonage protection, Garden hoses attached to chemical sprayers, submerged in a swimming pool, etc., can allow contaminants to be backsiphoned into the City's distribution system. Commercial operators must fit chemical tanks with air gap devices. lnigation systems are a potential cross-connection so make certain to do the following: 1. Confirm that your irrigation system is equipped with an approved backflow assembly. lf your system is not equipped with a backflow preventer, get one installed. 2. Testthe backflow assembly annually. Water Conservation fip - Use your water meter to dr:tect hidden leaks. Check the meter reading, and then turn off all water faucets and water using appliances Check the meter n after 15 minutes of no water use. lf the have a leak that needs to be red The mission of the City of St. George, Water Services Department is to provide our community with safe, drinking water at a reasonable price.
