Home My WebLink AboutDDW-2024-012451 1 Annual Drinking Water Quality Report South Duchesne Culinary Water 2023 We are pleased to present to you this year's Annual Drinking Water Quality Report. This report is designed to inform you about the quality of the water and services we deliver to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. Our water source(s) have been determined to be from surface water. Our water source is Duchesne Water UTAH07001 The Drinking Water Source Protection Plan for South Duchesne Culinary is available for your review. It contains information about source protection zones, potential contamination sources and management strategies to protect our drinking water. Our sources have been determined to have a medium level of susceptibility from potential contamination sources. We have also developed management strategies to further protect our sources from contamination. Please contact us if you have questions or concerns about our source protection plan. 2 There are many connections to our water distribution system. When connections are properly installed and maintained, the concerns are very minimal. However, unapproved and improper piping changes or connections can adversely affect not only the availability, but also the quality of the water. A cross connection may let polluted water or even chemicals mingle into the water supply system when not properly protected. This not only compromises the water quality but can also affect your health. So, what can you do? Do not make or allow improper connections at your homes. Even that unprotected garden hose lying in the puddle next to the driveway is a cross connection. The unprotected lawn sprinkler system after you have fertilized or sprayed is also a cross connection. When the cross connection is allowed to exist at your home, it will affect you and your family first. If you’d like to learn more about helping to protect the quality of our water, call us for further information about ways you can help. This report shows our water quality and what it means to you, our customer. Our Water System is currently on a Corrective Action Plan. If you have any questions about this report or concerning your water utility, please contact Josh Crowther at 435-224-2354. We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of our periodic meetings. They are generally held via Zoom online. Please contact Josh for further information. South Duchesne Culinary Water routinely monitors contaminants in our drinking water in accordance with the Federal and Utah State laws. The following table shows the results of our monitoring for the period of January 1st to December 31st, 2023. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants. It's important to remember that the presence of these constituents does not necessarily pose a health risk. In the following table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we've provided the following definitions: Non-Detects (ND) - laboratory analysis indicates that the constituent is not present. ND/Low - High - For water systems that have multiple sources of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table. Parts per million (ppm) or Milligrams per liter (mg/l) - one part per million corresponds to one minute in two years or a single penny in $10,000. Parts per billion (ppb) or Micrograms per liter (ug/l) - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000. 3 Parts per trillion (ppt) or Nanograms per liter (nanograms/l) - one part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000. Parts per quadrillion (ppq) or Picograms per liter (picograms/l) - one part per quadrillion corresponds to one minute in 2,000,000,000 years or one penny in $10,000,000,000,000. Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water. Millirems per year (mrem/yr) - measure of radiation absorbed by the body. Million Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers. Nephelometric Turbidity Unit (NTU) - nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person. Action Level (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. Treatment Technique (TT) - A treatment technique is a required process intended to reduce the level of a contaminant in drinking water. Maximum Contaminant Level (MCL) - The “Maximum Allowed” (MCL) is the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. Maximum Contaminant Level Goal (MCLG) - The “Goal”(MCLG) is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum Residual Disinfectant Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem out-dated. Waivers (W)- Because some chemicals are not used or stored in areas around drinking water sources, some water systems have been given waivers that exempt them from having to take certain chemical samples, these waivers are also tied to Drinking Water Source Protection Plans. 4 TEST RESULTS Contaminant Violatio n Y/N Level Detected ND/Low- High Unit Measurement MCLG MCL Date Sample d Likely Source of Contamination Microbiological Contaminants Total Coliform Bacteria N 2 N/A 0 Presence of coliform bacteria in 5% of monthly samples 2023 Naturally present in the environment Fecal coliform and E.coli N 0 N/A 0 If a routine sample and repeat sample are total coliform positive, and one is also fecal coliform or E. coli positive 2023 Human and animal fecal waste Turbidity for Surface Water N 0.56 NTU N/A 0.5 in at least 95% of the samples and must never exceed 5.0 2023 Soil Runoff (highest single measurement & the lowest monthly percentage of samples meeting the turbidity limits) Inorganic Contaminants Arsenic N ND-1 ppb 0 10 2020 Erosion of natural deposits; runoff from orchards; runoff from glass and electronics production wastes Copper a. 90% results b. # of sites that exceed the AL N a.49 b.0 ppb 1300 AL=1300 2021 Corrosion of household plumbing systems; erosion of natural deposits Lead a. 90% results b. # of sites that exceed the AL N a.0.7 b.0 ppb 0 AL=15 2021 Corrosion of household plumbing systems, erosion of natural deposits Disinfection By-products TTHM [Total trihalomethanes] N ND-80 ppb 0 80 2023 By-product of drinking water disinfection Haloacetic Acids N 30.1 ppb 0 60 2023 By-product of drinking water disinfection Chlorine Y* 0.5 ppb 4000 4000 2023 Water additive used to control microbes *Chlorine Residual Monitoring Violation We periodically monitor Chlorine Residual in the distribution system to meet all regulatory requirements. In the first quarter of 2023 we failed to take the required samples. Testing for a Chlorine Residual is used to ensure that the public is provided with safe drinking water. This violation does not necessarily pose a health risk. We have reviewed why we failed to take the required samples and will take steps to ensure that it will not happen again. 5 *Total Coliform: The Total Coliform Rule requires water systems to meet a stricter limit for coliform bacteria. Coliform bacteria are usually harmless, but their presence in water can be an indication of disease-causing bacteria. When coliform bacteria are found, special follow-up tests are done to determine if harmful bacteria are present in the water supply. If this limit is exceeded, the water supplier must notify the public by newspaper, television or radio. To comply with the stricter regulation, we have increased the average amount of chlorine in the distribution system. 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 components associated with service lines and home plumbing. South Duchesne Culinary is responsible for providing high quality drinking water but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead. All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or manmade. 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. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at 1-800-426- 4791. MCLs are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect. Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons 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 from their health care providers about drinking water. EPA/CDC guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline (800-426-4791). We at South Duchesne Culinary strive to provide top quality water to every tap. We ask that all our customers help us protect our water sources, which are the heart of our community and our way of life.
