Each report contains water quality information for the respective water system for the calendar year 2023 or the most recent sample data. These reports were delivered to the district’s wholesale customers via email on April 1, 2024. The Sand Hollow Wells – Sky Ranch & Cliff Dwellers CCR and the Cottam Wells – Casa de Oro & Homespun Village CCR were mailed directly to retail customers in June 2024. Each report is also listed on the district’s website. If you have any questions, please contact me at 435-673-3617. Respectfully, Brie Thompson Associate General Manager 435.673.3617 brie@wcwcd.gov Enclosures: 2023 Consumer Confidence Reports for: Cottam Wells (UTAH27071) Cottam Wells (UTAH27071) – Casa de Oro/Homespun Sand Hollow Wells (UTAH27073) – Hurricane City Sand Hollow Wells (UTAH27073) – Sky Ranch & Cliff Dwellers Kayenta Water Users (UTAH27085) Regional System (UTAH27094 & UTAH27073) 2023 Annual Drinking Water Quality Report Site: Cottam Wells; Utah System #27071 Source: Ground water Serves: Hurricane, La Verkin, Toquerville, and Virgin Executive summary: The Cottam Wells met or surpassed all federal and state health and safety requirements. Washington County Water Conservancy District (WCWCD) will continue monitoring the quality, treatment and sustainability of all its water sources to preserve and protect our current and future supply. About this report: The Environmental Protection Agency (EPA) requires the monitoring of more than 80 contaminants. The contaminants listed on the following chart were discovered in this water source. 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 water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (1.800.426.4791). Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, persons 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. 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. The WCWCD 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 epa.gov/safewater/lead. Protecting your water source: A drinking water source protection plan for the Cottam Wells is available at the WCWCD office. The plan includes information about source protection zones, potential contamination sources and management strategies to protect our drinking water. One common source of contamination is cross connections – any connection not properly protected by a backflow protection device that allows polluted water or chemicals to enter the water supply system. This can be as simple as a hose-end sprayer used to fertilize or apply pesticides. WCWCD encourages all water users to not make or allow improper connections due to its potential adverse effects on our water supply, the community and its residents. Additional information: Customers desiring to know more about their water utility can contact the WCWCD offices at 435.673.3617 or attend one of our regularly scheduled board meetings.

Retail water line ownership A retail water line is a pipe that connects a property to a public retail provider’s main water line. The Washington County Water Conservancy District owns the segment of each retail water line that connects the main water line to the water meter. After the meter, the customer owns the retail water line. Any repairs to or replacement of water lines after the water meter are the responsibility of the property owner. Protecting your water source: A drinking water source protection plan for the Cottam Wells is available at the WCWCD office. The plan includes information about source protection zones, potential contamination sources and management strategies to protect our drinking water. Important tips 1. Properly use and dispose of household chemicals and prescription medications 2. Prevent chemical runoff into storm drains or groundwater 3. Avoid cross connections A cross connection is a physical connection (piping) between a drinking water system and anything else, including another water supply, that can allow pollutants or contaminants to backflow into the drinking water system. Contamination may occur if a connection to a drinking water system is not protected by a backflow device, and polluted water or chemicals enter the drinking water system. An example of a cross connection can be as simple as using a hose-end sprayer to fertilize or apply pesticides. WCWCD encourages all water users to understand the different ways cross connections can occur, and to not make or allow improper connections due to potential adverse effects on our water supply, the community and its residents.

While your drinking water meets EPA’s standards for arsenic, it does contain low levels of arsenic. EPA’s standard 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 low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, persons 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. While your drinking water meets EPA’s standards for arsenic, it does contain low levels of arsenic. EPA’s standard 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 low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems. 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. The WCWCD 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 epa.gov/safewater/lead. Protecting your water source: A drinking water source protection plan for the Ence Wells is available at the WCWCD office. The plan includes information about source protection zones, potential contamination sources and management strategies to protect our drinking water. One common source of contamination is cross connections – any connection not properly protected by a backflow protection device that allows polluted water or chemicals to enter the water supply system. This can be as simple as a hose-end sprayer used to fertilize or apply pesticides. WCWCD encourages all water users to not make or allow improper connections due to its potential adverse effects on our water supply, the community and its residents. Additional information: Customers desiring to know more about their water utility can contact the WCWCD offices at 435.673.3617 or attend one of our regularly scheduled board meetings.

Glossary Maximum Contaminant Level (MCL) – Highest level of a contaminant 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) – 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) – 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) – 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. 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. None Established (NE) – MCL or MCLG has not been established for particular contaminant. Not Applicable (NA) – Violation is not applicable because the EPA has not established an MCL for particular contaminant. Parts per million (ppm) – One part per million is a unit that represents 1 part contaminant in 1,000,000 parts water. In water applications, one part per million is also equivalent to 1 milligram per liter (mg/L). Parts per billion (ppb) – One part per billion is a unit that represents 1 part contaminant in 1,000,000,000 parts water. In water applications, one part per billion is also equivalent to 1 microgram per liter (ug/L). Picocuries per Liter (pCi/L) – Picocuries per liter is a measure of the radioactivity in water. Treatment Technique (TT) – EPA requires process intended to reduce the level of a contaminant in drinking water. Year Sampled – WCWCD is allowed to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some data, though representative, are more than one year old. 2023 Annual Drinking Water Quality Report Site: Quail Lake System; Utah System #27094 Sand Hollow Wells; Utah System #27073 Source: Surface water (Quail Creek WTP) & ground water (Sand Hollow Wells) Serves: St. George, Washington, Ivins, Santa Clara, and Hurricane (Regional Pipeline, Sand Hollow Regional Pipeline) Executive summary: The Quail Lake System meets or surpasses all federal and state health and safety requirements. Washington County Water Conservancy District (WCWCD) will continue monitoring the quality, treatment and sustainability of all its water sources to preserve and protect our current and future supply. About this report: The Environmental Protection Agency (EPA) requires the monitoring of more than 80 contaminants. The contaminants listed on the following chart were discovered in this water source. 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 water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (1.800.426.4791). Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, persons 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. Some water sources in this system have arsenic concentrations in excess of EPA’s standard; however, under an arsenic blending plan, approved by the Utah Division of Drinking Water, these sources are being blended with sources which have lower arsenic concentrations to ensure the water reaching our customers is not in violation of EPA’s standard. While your drinking water meets EPA’s standards for arsenic, it does contain low levels of arsenic. EPA’s standard 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 low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.
