Box 144830 Salt Lake City, Utah 84114-4830 Dear Brandi Smith: Subject: Consumer Confidence Report for Kane County Water Conservancy District Johnson Canyon System #13038 Enclosed is a copy of the Johnson Canyon Consumer Confidence Report for the Kane County Water Conservancy District System #13038. It contains the water quality information for our water system for the calendar year 2023 or the most recent sample data. Since this system is between 500-10,000 in population, the District will notify its customers by posting on its monthly billing statement that a copy of the CCR is available at the District office or can be mailed out upon request. The district will also publish the CCR in a report in the SUN newspaper on June 27th, 2024. If you have any questions, please contact me at (435) 644-3997 Sincerely, Amanda Buhler, Office Manager Kane County Water Conservancy District Enclosure: Consumer Confidence Report 2023 Annual Drinking Water Quality Report Kane County Water Conservancy District Johnson Canyon Wells#1, #2, #3 – System #13038 We're 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 is the Lamb Point Tongue of the Navajo Sandstone Aquifer. The Lamb Point Tongue lies beneath the Tenney Canyon Tongue of the Kaenta Formation and above the Kaenta Formation. The Lamb Point Tongue ranges up to 400 feet thick and typically provides abundant high-quality water, particularly in the lower section. We have three well sources, which are located in Johnson Canyon. Our number one well site is approximately 5 miles north of Johnson Canyon road and U.S. 89 intersection about 10 miles east of Kanab, Utah. Our number two well site is located approximately 3 mile north of well site number 1 on the west side of the road. Our number three well is 5 approximately miles north of well site number two also located on the west side of the road. Kane County Water has a Drinking Water Source Protection Plan (DWSSP) that is available for your review. It provides more information such as potential sources of contamination and our source protection areas. It has been determined we have a low susceptible level of potential sources of contamination. The Drinking Water Source Protection Plan for Johnson Canyon 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 no potential contamination sources in protection zones 1 and 2. However, potential contamination does exist in zones 3 and 4 as a result of residential septic systems. There is 1 septic system in zone 3, which is 4,700 feet from well#1. There are 4 septic systems in zone 4, which are between 6,000 – 16,000 feet from well#1. For well#2, there is no potential contamination in zones 1 and 2. However, there is 1 septic system in zone 3 and 3 septic systems in zone 4. 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. 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. The Kane County Water Conservancy District is pleased to report that our drinking water meets federal and state requirements. This report shows our water quality and what it means to you our customer. If you have any questions about this report or concerning your water utility, please contact Amanda Buhler at (435) 644-3997 or e-mail her at kanecowater@gmail.com. We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of our regularly scheduled meetings. They are normally held on the 2nd Thursday of each month in the KCWCD conference room at 6:00PM. Kane County Water Conservancy District routinely monitors for constituents 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 constituents. 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. 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 outdated. 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.

Immuno-compromised 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 about drinking water from their health care providers. 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 the Kane County Water Conservancy District work around the clock 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, our way of life and our children’s future.
