DISCUSSION: The District is required under the Lead and Copper Rule to prepare a lead service line inventory which identifies the material of water services on both the District side of the meter and customer side of the meter. The District issued a Request for Proposals (RFP) at the end of 2024 to engage a consultant to assist with the preparation of the baseline inventory, develop a workplan to be approved by the Department of Drinking Water, provide field survey support and prepare final reporting. The District issued Task Order No. 1 to prepare the initial inventory and workplan. The purpose of this item is to approve the remaining work which includes updating the final inventory, preparing a final report and presentation, and continued project management. The District did not utilize the consultant to assist with developing a plan for the field surveys which saved approximately $30,000 from the original proposal. The cost for the remaining amount of work to complete the inventory is $18,100. Staff recommend that this Task Order amendment be approved so that the inventory may be completed and submitted before the end of the calendar year.

DISCUSSION: A Public Health Goals Report is required to be prepared by July 1, 2025, for water utilities that have greater than 10,000 service connections and their water quality measurements have exceeded any Public Health Goals (PHGs). PHGs are non- enforceable goals established by the California Environmental Protection Agency (Cal EPA) Office of Environmental Health Hazard Assessment (OEHHA). Public Health Goals are different from Maximum Contaminant Levels (MCLs - the legal maximum level for any contaminant in drinking water). Public Health Goals do not take into account available treatment technologies, detection technology, or cost, whereas MCLs do take those things into account. If a constituent was detected in the South Tahoe Public Utility District’s (District) water supply between 2022 and 2024 at a level exceeding an applicable PHG or Maximum Contaminant Level Goal (MCLG), this report provides the information required by law. Included is the numerical public health risk associated with the MCL and the PHG or MCLG, the category or type of risk to health that could be associated with each constituent, the best treatment technology available that could be used to reduce the constituent level, and an estimate of the cost to install that treatment if it is appropriate and feasible.

PHGs are non-enforceable goals established by the California Environmental Protec#on Agency (Cal EPA) Office of Environmental Health Hazard Assessment (OEHHA). The law also requires that where OEHHA has not adopted a PHG for a cons#tuent, the water suppliers are to use the maximum contaminant level goals (MCLG) adopted by the United States Environmental Protec#on Agency (US EPA). Only cons#tuents which have a California primary drinking water standard and for which either a PHG or MCLG has been set are to be addressed. (Reference No. 2 is a list of all regulated cons#tuents with the MCLs and PHGs or MCLGs). There are a few cons#tuents that are rou#nely detected in water systems at levels usually well below the drinking water standards for which no PHG nor MCLG has yet been adopted by OEHHA or US EPA including Total Trihalomethanes. These will be addressed in a future required report a;er a PHG has been adopted. If a cons#tuent was detected in the South Tahoe Public U#lity District’s (District) water supply between 2022 and 2024 at a level exceeding an applicable PHG or MCLG, this report provides the informa#on required by the law. Included is the numerical public health risk associated with the MCL and the PHG or MCLG, the category or type of risk to health that could be associated with each cons#tuent, the best treatment technology available that could be used to reduce the cons#tuent level, and an es#mate of the cost to install that treatment if it is appropriate and feasible. What Are Public Health Goals? Public Health Goals (PHGs) are set by the California Office of Environmental Health Hazard Assessment (OEHHA) which is part of Cal-EPA and are based solely on public health risk considera#ons. None of the prac#cal risk-management factors that are considered by the US EPA or the California Division of Drinking Water in se?ng drinking water standards (MCLs) are considered in se?ng the PHGs. These factors include analy#cal detec#on capability, treatment technology available, benefits and costs. The PHGs are not enforceable and are not required to be met by any public water system. MCLGs are the federal equivalent to PHGs. Water Quality Data Considered All the water quality data collected by South Tahoe Public U#lity District between 2022 and 2024 for purposes of determining compliance with drinking water standards was considered. This data was all summarized in our 2022, 2023, and 2024 Consumer Confidence Reports. (Reference No. 3) Guidelines Followed The Associa#on of California Water Agencies (ACWA) formed a work group which prepared guidelines for water u#li#es to use in preparing these newly required reports. The ACWA guidelines were used in the prepara#on of our report. No guidance was available from state regulatory agencies. Best Available Treatment Technology and Cost Es#mates Both the US EPA and California Division of Drinking Water (DDW) adopt what are known as BATs or Best Available Technologies which are the best-known methods of reducing contaminant levels to the maximum contaminant level (MCL). Costs can be es#mated for such technologies. However, since many PHGs and all MCLGs are set much lower than the MCL, it is not always possible nor feasible to determine what treatment is needed to further reduce a cons#tuent downward to or near the PHG or MCLG, many of which are set at zero. Es#ma#ng the costs to reduce a cons#tuent to zero is difficult, if not impossible. It is some#mes not possible to verify by analy#cal means that the level has been lowered to zero. In some cases, installing treatment to try and further reduce very low levels of one cons#tuent may have adverse effects on other aspects of water quality. Cons#tuents Detected That Exceed a PHG or a MCLG The following is a discussion of cons#tuents that were detected in one or more of the District’s drinking water sources at levels above the PHG, or if no PHG, above the MCLG. Chemical Health Risk Category California PHG (mg/L or ppm) Cancer Risk at the PHG California MCL (mg/L or ppm) Cancer Risk at the California MCL Arsenic Carcinogenicity (causes cancer) 0.000004 (4x10-6) 1x10-6 (one per million) 0.01 2.5x10-3 (2.5 per thousand) Uranium Carcinogenicity (causes cancer) 0.43 pCi/L 1x10-6 (one per million) 20 pCi/L 5x10-5 (five per hundred thousand) Perfluoro- octanoicacid (PFOA) Carcinogenicity (causes cancer) 7x10-9 1x10-6 (one per million) NA NA Arsenic The contamina#on of a drinking water source by arsenic can result from either natural or human ac#vi#es. Arsenic is an element that occurs naturally in rocks and soil, water, air, plants and animals. Volcanic ac#vity, the erosion of rocks and minerals, and forest fires are natural sources that can release arsenic into the environment. Although about 90 percent of the arsenic used by industry in the United States is used for wood preserva#ve purposes, arsenic is also used in paints, drugs, dyes, soaps, metals and semi-conductors. Burning fossil fuels and waste, paper produc#on, glass manufacturing, cement manufacturing, mining and smel#ng can also release arsenic. While arsenic can no longer be used in making pes#cides and weed killers, the US EPA is aware that these substances have contributed to drinking water contamina#on. The PHG for Arsenic is 0.004 micrograms per liter (ug/L or parts per billion). The MCL or drinking water standard for arsenic is 10 ppb. The District detected arsenic levels above the PHG but not exceeding the MCL in the discharge from eight (8) District Wells listed below. The average of the samples taken between 2022 and 2024 are shown in the table below. Well Arsenic (ppb) 2022 - 2024 Average Arrowhead #3* 3.2 Bakersfield 8.2 Bayview 2.0 Elks Club #2 1.3 Helen #2 6.2 South Upper Truckee #3 1.7 Sunset 3.8 Valhalla 1.9 * Arrowhead Well #3 is equipped with wellhead treatment for Arsenic removal and the level reported is a;er treatment Some people who drink water containing arsenic in excess of EPA’s standard over many years may experience skin damage or circulatory system problems and may have an increased risk of ge?ng cancer. OEHHA has determined that the health risk associated with arsenic is an increased risk of cancer. Numerical health risk data provided by OEHHA determined the health risk associated with the PHG is one (1) excess case of cancer in a million people and the health risk associated with the MCL is two and a half (2.5) excess cases of cancer in 1,000 people over life#me of exposure. The best available technology for arsenic treatment is Ac#vated Alumina, Coagula#on/Filtra#on, Lime So;ening, Ion Exchange and Reverse Osmosis. These treatment methods would require more consulta#on beyond the scope of this report to determine the appropriate treatment for each well site. Some of the well sites do not have enough land to install/construct a wellhead treatment facility, therefore acquisi#on of land and associated piping to the facility would be required. For the purpose of this report, adsorp#on using iron oxide will be selected because that is what the District u#lizes at the Arrowhead Well to remove arsenic. Treatment for the wells listed above (excluding Arrowhead Well #3) is es#mated to have an annualized capital and opera#on and maintenance (O&M) cost could range from approximately $3,000,000 to $4,000,000 per year1. That would result in an assumed increased cost for each water customer ranging from $215 to $285 per year. 1 Estimate based on Cost Estimates for Treatment Technologies from 2012 ACWA Survey Uranium Uranium is a naturally occurring radioac#ve element that is found in many types of rocks. Uranium is found in ground and surface waters due to its natural occurrence in geological forma#ons. The PHG for Uranium (U) is 0.43 picoCuries per liter (pCi/L). The MCL or drinking water standard for Uranium is 20 pCi/L. The District detected uranium levels above the PHG but not exceeding the MCL in the discharge from ten (10) District Wells listed below. The average of the samples taken between 2022 and 2024 are shown in the table below: Well Uranium (pCi/L) 2022 - 2024 Average Al Tahoe #2 1.18 Arrowhead #3 13.4 Bakersfield 8.57 Bayview 0.92 Elks Club #2 1.67 Glenwood #5 5.87 Helen #2 7.37 South Upper Truckee #3 0.78 Sunset 8.03 Valhalla 0.93 Some people who drink water containing uranium in excess of the MCL over many years may have kidney problems or an increased risk of ge?ng cancer. Numerical health risk data provided by OEHHA determined the health risk associated with the PHG is one (1) excess case of cancer in a million people and the health risk associated with the MCL is five (5) excess cases of cancer in 100,000 people over life#me of exposure. The best available technology for Uranium treatment is Coagula#on/Filtra#on, Ion Exchange, Lime So;ening and Reverse Osmosis. These treatment methods would require more consulta#on beyond the scope of this report to determine the appropriate treatment for each well site. Some of the well sites do not have enough land to install/construct a wellhead treatment facility, therefore acquisi#on of land and associated piping to the facility would be required. For the purpose of this report, ion exchange will be selected for treatment. The disposal of the spent media for Uranium treatment is complex due to the radioac#ve nature of the element which can result in a wide range in O&M cost. Ion Exchange for the wells listed above is es#mated to have an annualized capital and O&M cost could range from approximately $4,000,000 to $8,000,000 per year2. That would result in an assumed increased cost for each water customer ranging from $286 to $571 per year. 2 Estimate based on Cost Estimates for Treatment Technologies from 2012 ACWA Survey PFOA Star#ng in the 1940s, perfluorooctanoic acid (PFOA) was widely used in industrial applica#ons and consumer products, including carpets, rugs, upholstered furniture and non-s#ck cookware. PFOA has also been present in some firefigh#ng foams used at airports, firefighter training facili#es and military airfields. Notably, PFOA in nons#ck cookware and PFOS in stain and water-repellant fabrics and in fire- figh#ng foams. The manufacture of these chemicals was phased out in the US following concerns about their extreme persistence in the environment and their detec#on in virtually all human blood serum samples, however, may s#ll be present in some imported products. Although levels in the environment have declined from their peak around the year 2000, PFOA and PFOS con#nue to be present in the environment and are found in California drinking water. The US EPA’s MCL for PFOA is 4 ppt (parts-per-trillion), and the PHG for PFOA is 0.007 ppt. The District detected PFOA levels above the PHG but not exceeding the MCL in the discharge from one (1) District Well listed below. The average of the samples taken between 2022 and 2024 are shown in the table below: Helen Well #2 – 3.1 ppt OEHHA has determined that the health risk associated with PFOA is an increased risk of cancer. Numerical health risk data provided by OEHHA determined the health risk associated with the PHG is one (1) excess case of cancer in a million people. The best available technology for PFOA treatment is Ion exchange, granular ac#vated carbon, reverse osmosis and nanofiltra#on. These treatment methods would require more consulta#on beyond the scope of this report to determine the appropriate treatment. For the purpose of this report, granulated ac#vated carbon will be selected for treatment. The capital cost for granulated ac#vated carbon wellhead treatment would likely be between $3,000,000 to $5,000,000 due to the need for a building and poten#ally addi#onal land. That would result in an assumed increased cost for each water customer ranging from $15 to $21 per year. Recommenda#ons For Further Ac#on The drinking water quality of the South Tahoe Public U#lity District meets all State of California, Division of Drinking Water, and US EPA drinking water standards set to protect public health. To further reduce the levels of the cons#tuents iden#fied in this report that are already significantly below the health- based Maximum Contaminant Levels established to provide “safe drinking water,” addi#onal costly treatment processes would be required. The effec#veness of the treatment processes to provide any significant reduc#ons in cons#tuent levels at these already low values is uncertain. The health protec#on benefits of these further hypothe#cal reduc#ons are not clear and may not be quan#fiable. The District is developing a Water Supply Master Plan and evalua#ng public health goals and poten#al for wellhead treatment be considered as a part of that process.

Last year, as in years past, your tap water met all U.S. Environmental Protection Agency (EPA) and state drinking water health standards. The South Tahoe Public Utility District vigilantly safeguards its water supplies, and we are proud to report that our source water has not violated a maximum contaminant level or any other water quality standard. 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, 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/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the USEPA’s Safe Water Drinking Hotline (1-800-426-4791). WHERE DOES MY WATER COME FROM? There are 11 active drinking water wells and 4 standby wells which supply more than 14,000 homes and businesses. All our drinking water is pumped from underground aquifers. No water is taken from Lake Tahoe or any other surface water source. SOURCE WATER ASSESSMENT AND PROTECTION The District continues to work diligently to protect and maintain our groundwater quality and adequate water supply. The District’s Groundwater Management Plan (California Water Code Section 10750) was adopted on December 4, 2014, and is on file with the California Department of Public Health (CDPH). You may view the document by visiting the District’s website at www.stpud.us or by requesting a copy by calling Customer Service at 530-544-6474. The District has an ongoing drinking water source development program that seeks potential drinking water well locations. Due to the volume of the average annual Sierra snowpack and Lake Tahoe itself, our aquifer has a significant recharge capability. HOW DO CONTAMINANTS GET INTO DRINKING 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 necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline (1-800-426-4791). 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, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Microbial contaminants, such as viruses and bacteria, may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic contaminants, such as salts and metals, can be naturally occurring or result from urban stormwater runoff, industrial, or domestic wastewater discharges, oil and gas production, mining, or farming. Pesticides and herbicides may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. Organic chemical contaminants, including synthetic and volatile organic chemicals, are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, agricultural application, and septic systems. Radioactive contaminants can be naturally occurring or be the result of oil and gas production and mining activities. Many of these contamination sources do not exist in Lake Tahoe. In order to ensure that tap water is safe to drink, the United States Environmental Protection Agency (USEPA) and the California Department of Public Health (DPH) prescribe regulations that limit the amount of certain contaminants in water provided 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. HOW CAN I FIND OUT MORE? The information contained in the Consumer Confidence Report may not answer all the questions you may have about the quality of the South Tahoe Public Utility District’s drinking water supply. If you would like more detailed information, please call the District Laboratory at 530-543-6231 or check our website at www.stpud.us. The District is governed by an elected five-member Board of Directors. Board meetings are held on the first and third Thursday of each month at 2 p.m. at the Customer Service Facility located at 1275 Meadow Crest Drive. All meetings are open to the public and the District encourages our customers to attend, ask questions, and provide feedback. RESULTS OF RADON MONITORING Radon is a radioactive gas that cannot be seen, tasted, or smelled. It is found throughout the U.S. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activities. Compared to radon entering the home through soil, radon entering the home through tap water will, in most cases, be a small source of radon in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may cause an increased risk of stomach cancer. If you are concerned about radon in your home, you can test the air in your home. For additional information on radon, call your state radon program or the EPA’s Radon Hotline (800-SOS-RADON). RESULTS OF VOLUNTARY MONITORING See data sheets. REGARDING ARSENIC Arsenic is a naturally occurring substance that is sometimes found at low levels in drinking water, particularly groundwater. The South Tahoe Public Utility District has an active Arsenic monitoring program, as well as a pilot Arsenic removal system in one of its wells.

WATER QUALITY DATA TABLE The table below lists all the drinking water contaminants detected which are applicable for the calendar year of this report. The presence of contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires us to monitor for certain contaminants less often than once per year because the concentrations of these contaminants do not change frequently. ADDITIONAL CONTAMINANTS In an effort to ensure the safest water possible, the State has required us to monitor some contaminants not required by Federal regulations. Of those contaminants only the ones listed on the last page under “Additional Contaminants” were found in your water. IMPORTANT DRINKING WATER DEFINITIONS AL Allowed Limit: Limit for 90th percentile of samples. MCL Maximum Contaminant Level: 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. MCLG Maximum Contaminant Level Goal: 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. MRDL Maximum Residual Disinfectant Level: 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. MRDLG Maximum Residual Disinfection Level Goal: 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. PDWS Primary Drinking Water Standards: MCLs for contaminants that affect health along with their monitoring and reporting requirements, and water treatment requirements. PHG Primary Health Goal: The level of contaminant in drinking water below which there is no known or expected risk to health. PHGs are set by the California Environmental Protection Agency.

Some of the more well-known ones include PCBs, Atrazine, Florene, Dioxins and Caffeine. SOC’s health effects include damage to the nervous system and cancer risks. The District last tested for these chemicals in 2021. ADDITIONAL MONITORING As part of an ongoing evaluation program called UCMR (Unregulated Contaminant Monitoring Rule), the Environmental Protection Agency requires the District to monitor a number of additional contaminants/ chemicals. Information collected through this monitoring provides information for future decisions on drinking water standards. UCMR-3 The District was required to monitor our source water for 28 chemical contaminants. The first round was completed in August 2014 and the second round in February 2015. In the absence of identifiable industrial sources, these contaminants are naturally occurring in our watershed. Chlorate is an exception and is a degradation product of the disinfectant used by the District for drinking water. UCMR-4 In this round of UCMR, the District was required to monitor for 18 chemical contaminants, as well as the Total Organic Carbon (TOC) content in our Source Water. The first round was completed in January 2019 and the second round in July 2019. These contaminants included metals like Germanium, volatile Pesticides and their byproducts such as alpha-HCH, volatile Alcohols like 1-Butanol and Tar/Oil byproducts like Quinoline. The District also tested its distribution system for 9 disinfection byproducts, collectively known as Haloacetic Acids (HAA9).

SOURCE WATER ASSESSMENT AND PROTECTION The District continues to work diligently to protect and maintain our groundwater quality and adequate water supply. The District’s Groundwater Management Plan (California Water Code Section 10750) is on file with the California Department of Public Health (CDPH). You may view the document by visiting the District’s website at www.stpud.us or by requesting a copy by calling Customer Service at 530-544- 6474. The District has an ongoing drinking water source development program that seeks potential drinking water well locations. Due to the volume of the average annual Sierra snowpack and Lake Tahoe itself, our aquifer has a significant recharge capability. HOW DO CONTAMINANTS GET INTO DRINKING 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 necessarily indicate that 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 (800-426-4791). 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 can dissolve naturally occurring minerals and, in some cases, radioactive materials, and can pick up substances resulting from the presence of animals or from human activity. Microbial contaminants, such as viruses and bacteria, may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic contaminants, such as salts and metals, can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharge, oil and gas production, mining, or farming. Pesticides and herbicides may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses. Organic chemical contaminants, including synthetic and volatile organic chemicals, are by- products of industrial processes and petroleum production, and can also 1 South Tahoe Public Utility District C O N S U M E R C O N F I D E N C E R E P O R T 2 O 2 3 come from gas stations, urban storm water runoff, and septic systems. Radioactive contaminants can be naturally occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in the water provided by public water systems. The Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for human health. RADON MONITORING Radon is a naturally occurring gas present in some groundwater. Inhaled radon has been linked to lung cancer and may pose a health risk when inhaled after the release from water into the air. This inhalation could occur during showering, bathing, washing dishes, or washing clothes. The radon gas released from drinking water is a relatively small part of the total radon found in air. One major source of radon gas is from the soil, where the gas can seep through the foundations of homes. It is not clear whether ingested (i.e. taken through the mouth) radon contributes to cancer or other adverse health conditions. If you are concerned about radon in your home, tests are available to determine the total exposure level. For additional information on home testing call your state radon program or EPA’s Radon Hotline (800-SOS-RADON). REGARDING ARSENIC While your drinking water meets EPA’s standard 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. INFORMATION ABOUT LEAD 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 District 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 the 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 www.epa.gov/safewater/lead. HOW CAN I FIND OUT MORE? If you would like more detailed information on your drinking water, please call Dan Arce in the District Laboratory at 530-544-6474 x6231 or check our website at www.stpud.us. The District is governed by an elected five-member Board of Directors. Board meetings are held on the first and third Thursday of each month at 2 p.m. at 1275 Meadow Crest Drive, South Lake Tahoe. All meetings are open to the public and the District encourages our customers to attend, ask questions, and provide feedback. 2 WATER QUALITY DATA TABLE The table below lists the drinking water contaminants monitored for the calendar year of this report. The presence of contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires us to monitor for certain contaminants less often than once per year because the concentrations of these contaminants do not change frequently. ADDITIONAL CONTAMINANTS In an effort to ensure the safest water possible, the State has required us to monitor some contaminants not required by Federal regulations. These contaminants are listed on Page 5 under “Additional Monitoring”. None were found in your water. IMPORTANT DRINKING WATER DEFINITIONS AL Allowed Limit: Limit for 90th percentile of samples. AVERAGE If the analyte was not detected in any samples, the average is reported as ‘non-detect’ (ND). If the analyte was detected in some, but not all samples, the average was calculated by considering ND results as half the reporting limit. MCL Maximum Contaminant Level: 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. MCLG Maximum Contaminant Level Goal: 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.

Data collected through this monitoring provides information for future decisions on drinking water standards. UCMR-5 Water agencies are required to sample for 30 additional chemicals between 2023 and 2025. This includes the metal Lithium and 29 chemicals collectively known as PFAS (per- and polyfluoroalkyl compounds). For a detailed explanation on the toxicity of these chemicals please visit: www.epa.gov/pfas. The District sampled each of its water sources at least two times between 2023 and 2024. Some sources were sampled more often to confirm results. NATIONAL PFAS STANDARDS In April 2024, the EPA established drinking water standards for five specific PFAS chemicals, including Maximum Contaminant Levels (MCL). The MCLs and monitoring results are expressed in Parts per Trillion (ppt). One part per trillion is equivalent to one second in 32,000 years. Of the drinking water wells tested, only one of the regulated chemicals (PFOA) was detected at one well. This well was tested four times in 2023/2024 and this chemical was below the EPA MCL limit three out of the four times. This well supplied less than 5% of the District’s drinking water in 2023.

Tradúzcalo o hable con alguien que lo entienda bien.PWS ID#: CA0910002 Presented By South Tahoe Public Utility District Our Commitment The South Tahoe Public Utility District (District) is pleased to present to you this year’s annual water quality report. This report is a snapshot of last year’s water quality covering all testing performed between January 1 and December 31, 2024. Included are details about your sources of water, what it contains, and how it compares to standards set by regulatory agencies. Our constant goal is to provide you with a safe and dependable supply of drink- ing water. We want you to understand the efforts we make to continually improve and protect our water resources. Where Does My Water Come From? The District’s network of 11 active wells supplies water to over 14,000 homes and businesses. All your drink- ing water is pumped from the aquifer beneath our feet – the Tahoe Valley South Subbasin. More information about our aquifer and groundwater management can be found at stpud. us/drinking-water. Important Health Information Some people may be more vulnerable to contami- nants 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 about drink- ing water from their health-care providers. U.S. Environmental Protection Agency (U.S. EPA)/Centers for Disease Control and Prevention (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at (800) 426-4791 or epa.gov/safewater. Substances That Could Be in Water 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, in some cases, radioactive material and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: Microbial Contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic Contaminants, such as salts and metals, that can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. Pesticides and Herbicides that may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. Organic Chemical Contaminants, including synthetic and volatile organic chemicals, that are by-products of industrial processes and petroleum production and can also come from gas stations, urban stormwater runoff, agricultural application, and septic systems. Radioactive Contaminants that can be naturally occurring or the result of oil and gas production and mining activities. To ensure that tap water is safe to drink, the U.S. EPA and the State Water Resources Control Board (SWRCB) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. U.S. Food and Drug Administration regulations and California law also establish limits for contaminants in bottled water that provide the same protection for public health. 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 U.S. EPA’s Safe Drinking Water Hotline at (800) 426-4791. Questions?For more information about this report, or for any questions relating to your drinking water, please call Dan Arce, Laboratory Director, at (530) 544-6474, ext. 6231. Source Water Assessment and Protection The District continues to work diligently to protect and maintain our groundwater quality and an adequate water sup- ply. The District’s Groundwater Management Plan (California Water Code, section 10750) is on file with the California Department of Public Health (CDPH). You may view the document by visiting the District’s website at stpud.us or request a copy by calling customer service at (530) 544-6474. The District has an ongoing drinking water source development program that seeks potential drinking water well locations. Due to the volume of the average annual Sierra snowpack and Lake Tahoe itself, our aquifer has a significant recharge capability. Groundwater in South Lake Tahoe is generally of excellent quality, though it has faced threats from both natural and human- made contaminants. Methyl tert butyl ether (MTBE) and tetrachloroethylene (PCE) plumes in the South Y area led the District to remove affected wells from service and develop new, uncontaminated sources. Naturally occurring arsenic, uranium, and gross alpha particle activity have been found in parts of the aquifer, with one District well requiring arsenic treatment to meet water quality standards. Infiltration basins used for stormwater recharge also pose potential risks, but these are effectively managed through careful well siting, design, and wellhead treatment. Testing for Radon Our wells were last monitored for radon in 2023 and test results were below the maximum contaminant level (MCL). Radon is a naturally occurring radioactive gas that you cannot see, taste, or smell. It is found throughout the U.S. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activi- ties. Compared to radon entering the home through soil, radon entering the home through tap water will, in most cases, be a small source in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon, test the air in your home. Testing is inexpensive and easy. You should pursue radon removal if the level of radon in your air is 4 picocuries per liter (pCi/L) of air or higher. There are simple ways to fix a radon problem. For additional information, call California’s Radon Program at (800) 745-7236, the U.S. EPA’s Safe Drinking Water Hotline at (800) 426-4791, or the National Safety Council Radon Hotline at (800) 767-7236. Community Participation The District is governed by an elected five-member board of directors. Board meetings are held on the first and third Thursday of each month at 2:00 p.m. in the District boardroom at 1275 Meadow Crest Drive. All meetings are open to the public, and the District encourages our customers to attend, ask questions, and provide feedback. What Are PFAS? Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals used worldwide since the 1950s to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. During production and use, PFAS can migrate into the soil, water, and air. Most PFAS do not break down; they remain in the environment, ultimately finding their way into drinking water. Because of their wide- spread use and their persistence in the environment, PFAS are found all over the world at low levels. Some PFAS can build up in people and animals with repeated exposure over time. The most commonly studied PFAS are perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). PFOA and PFOS have been phased out of production and use in the United States, but other countries may still manufacture and use them. Some products that may contain PFAS include: • Some grease-resistant paper, fast food containers/wrappers, microwave popcorn bags, pizza boxes • Nonstick cookware • Stain-resistant coatings used on carpets, upholstery, and other fabrics • Water-resistant clothing • Personal care products (shampoo, dental floss) and cosmetics (nail polish, eye makeup) • Cleaning products • Paints, varnishes, and sealants Even though recent efforts to remove PFAS have reduced the likelihood of exposure, some products may still contain them. If you have questions or concerns about products you use in your home, contact the Consumer Product Safety Commission at (800) 638-2772. For a more detailed discussion on PFAS, please visit atsdr.cdc.gov/pfas/index.html. Arsenic Regulation Arsenic contamination of drinking water sources may result from either natural or human activities. Volcanic activity, erosion of rocks and minerals, and forest fires are natural sources that can release arsenic into the environment. Although about 90 percent of the arsenic used by industry is for wood preservative purposes, it is also used in paints, drugs, dyes, soaps, metals, and semiconductors. Agricultural applica- tions, mining, and smelting also contribute to arsenic releases. Arsenic is usually found in the environment combined with other elements such as oxygen, chlorine, and sulfur (inorganic arsenic) or carbon and hydrogen (organic arsenic). Organic forms are usually less harmful than inorganic forms. Low levels of arsenic are naturally present in water--about 2 parts arsenic per billion parts water (ppb), so you normally take in small amounts of arsenic in the water you drink. Some areas of the country have unusually high natural levels of arsenic in rock, which can lead to unusually high levels of arsenic in water. In January 2001, the U.S. EPA lowered the arsenic MCL from 50 to 10 ppb in response to new and compelling research linking high arsenic levels in drinking water with certain forms of cancer. All water utilities were required to implement this new MCL in January 2006. Removing arsenic from drinking water is a costly procedure but well worth the expenditure considering the health benefits. For a more complete discussion, visit the U.S. EPA’s arsenic web page, epa.gov/dwreginfo/drinking-water-arsenic-rule-history. Test Results The following tables list the drinking water contaminants monitored for the calendar year of this report, unless otherwise noted. The presence of contaminants in the water does not necessarily indicate that the water poses a health risk. The U.S. EPA and SWRCB require us to monitor for certain contaminants less often than once per year based on results of previous testing. The District monitors for more contaminants than are listed in these tables. Contaminants not detected during testing are not shown in the tables. The state recommends monitoring for certain substances less than once per year because the concentrations of these substances do not change frequently. In these cases, the most recent sample data is included, along with the year in which the sample was taken. The District participated in the fifth stage of the U.S. EPA’s Unregulated Contaminant Monitoring Rule (UCMR5) program by performing additional tests on our drinking water. UCMR5 sampling benefits the environment and public health by providing the U.S. EPA with data on the occurrence of contaminants suspected to be in drinking water to determine if it needs to introduce new regulatory standards to improve drinking water quality.

Lead in Home Plumbing Lead can cause serious health effects in people of all ages, especially pregnant people, infants (both formula-fed and breastfed), and young children. Lead in drinking water is primarily from materials and parts used in service lines and in home plumbing. The District is responsible for providing high-quality drinking water and remov- ing lead pipes but cannot control the variety of materials used in the plumbing in your home. Because lead levels may vary over time, lead exposure is possible even when your tap sampling results do not detect lead at one point in time. You can help protect yourself and your family by identifying and removing lead materials within your home plumbing and taking steps to reduce your family’s risk. Using a filter certified by an American National Standards Institute-accredited certifier to reduce lead is effective in reducing lead exposures. Follow the instructions provided with the filter to ensure it is used properly. Use only cold water for drinking, cooking, and making baby formula. Boiling does not remove lead from water. Before using tap water for drinking, cooking, or making baby formula, flush your pipes for several minutes. You can do this by running your tap, taking a shower, or doing laundry or a load of dishes. If you have a lead or galvanized service line requiring replacement, you may need to flush your pipes for a longer period. If you are concerned about lead and wish to have your water tested, contact the District’s laboratory at (530) 544-6474, ext. 6231. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at epa.gov/safewater/lead. To address lead in drinking water, public water systems were required to develop and maintain an inventory of service line materials by October 16, 2024. Developing an inventory and identifying the location of lead service lines is the first step for beginning to replace lead service lines and protecting public health. While no lead water service lines have been identified in the District’s system to date, service lines with unknown materials are still being assessed. More information about the District’s lead service inventory may be found at stpud.us/water-service-line-inventory. Please contact us at (530) 544- 6474 if you would like more information about the inventory or lead sampling that has been done. Public Health Goals Report - 2025 Adrian Combes Director of Operations Public Health Goals Overview •The California Health and Safety Code requires that water districts with more than 10,000 service connections prepare a special report if their water quality measurements exceed any Public Health Goals. •Public Health Goals are non-enforceable goals established by California EPA’s Office of Environmental Health Hazard Assessment. •Public health goals are based solely on public health risk considerations and do not consider practical risk management factors like detection capability, treatment technology available, benefits and costs. •As a water district, we are required to meet maximum contaminant levels (MCLs), but not public health goals. Public Health Goals vs. MCLs •Maximum Contaminant Levels (MCL) are set by the U.S. Environmental Protection and by the California State Water Resources Control Board. •An MCL is the highest level of a contaminant that is legally permitted in public drinking water. •MCLs are set based on the best available technology for treatment, detection capability, benefits, and costs. •As a water district, we are required to meet maximum contaminant levels (MCLs), but not public health goals.

DISCUSSION: The South Tahoe Public Utility District (District) owns and operates 40 wastewater pump stations connected through approximately 48 miles of force main piping. Much of this infrastructure was constructed between 1955 and 1971 and includes numerous air release, vacuum, and combination air/vacuum valves (ARVs) that are essential to maintaining reliable force main operation and preventing air entrainment, surging, and other hydraulic instabilities. Many of these assets are at or beyond their expected service life and require varying levels of rehabilitation or replacement in the near future. To address these challenges, the District advertised a Request for Proposals (RFP) and received one Proposal from Schaaf & Wheeler, Consulting Civil Engineers (Shaaf & Wheeler) to perform a comprehensive Force main Hydraulic Analysis and ARV Assessment. District staff worked with Shaaf & Wheeler to refine the scope of this effort and the proposed work will evaluate the hydraulic performance and operational risks associated with 25 selected force mains and pump stations, identify deficiencies in ARV functionality or placement, and develop a prioritized Rehabilitation and Replacement (R&R) Plan for implementation in the District’s Capital Improvement Program (CIP). General Manager Paul Hughes Directors Nick Haven Shane Romsos Joel Henderson Kelly Sheehan Nick Exline Taylor Jaime Page 2 December 4, 2025 The proposed scope of work includes four primary tasks: (1) Data collection and review; (2) Force main and ARV hydraulic and transient analysis; (3) Development of a prioritized rehabilitation and replacement plan including standard details, technical specifications, and operation and maintenance procedures; and (4) Project management and coordination. The resulting deliverables will provide the District with a data-driven understanding of system risks, detailed improvement recommendations, and standardized design and maintenance resources for future ARV projects. The total fee for this work is $254,133 on a time-and-materials, not-to-exceed basis. Execution of the Master Services Agreement with Schaaf & Wheeler will be completed prior to execution of this Task Order. Work is anticipated to begin in December 2025 and be completed by December 2026. This assessment represents a critical first step toward modernizing the District’s pressurized wastewater conveyance system, improving operational reliability, and extending the service life of key infrastructure assets.

Tharp (Gilmore) PE Vice President RCE 76810 EXHIBIT A Page 1 of 5 Project Summary The South Tahoe Public Utilities District (District) currently owns, maintains, and operates 40 wastewater pump stations, covering approximately 48 miles of force main in the District. Construction materials for the existing force mains include asbestos cement, steel, and PVC pipe with ~139 air release valves that have been cataloged to date. Most of the existing force mains were constructed between 1955 and 1971. Exceptions to this include the Fallen Leaf Lake force mains (constructed between 1979 and 1983) and the Flanders, Gardner Mountain, Ponderosa, and Ski Run force mains, which were constructed after 1997. The District needs evaluation, assessment, and planning for near term capital improvements for force mains and associated air release valves, vacuum valves, and combination air/vacuum valves (collectively referred to as ARVs) that need to be added or are at or beyond their design life. The District specific goals for this project includes the following: ▪ Force Main Operation Reliability o Confirm the quantity and location of ARVs o Confirm the functionality of existing ARVs o Identify hydraulic inefficiencies and operational risks for selected force mains ▪ Prioritization of Capital Improvements o Provide short-term and long-term improvement and maintenance projects based on observed condition and modeled performance assessment of force mains and ARVs ▪ System Optimization o Identify locations where new ARVs are needed including sizing recommendations o Identify locations where existing ARVs can be removed or relocated ▪ Constructability and Practical Long-Term Maintenance Strategies o Develop strategies to minimize cost and system disruption o Assess the constructability and associated costs for selected sites and improvement strategies o Review station specific bypassing or flow storage methods required for selected sites o Provide detailed template technical specifications and standard details to be used for future improvement projects The District provided Schaaf & Wheeler with additional data for review including ARV records, as- built drawings, GIS data, and the sanitary sewer master plan. We will provide a preliminary prioritization of the higher risk force mains based on the criteria listed below: ▪ Number of ARVs>1 ▪ Forcemain Material is ACP or VCP ▪ Forcemain Length > 1,000 feet ▪ Forcemain Diameter > 8 inches ▪ Pump Station Capacity > 1,000 gpm ▪ Pump Station TDH > 50 feet EXHIBIT A Page 2 of 5 A preliminary scoping meeting with the District resulted in the removal of the following pump stations from the scope. ▪ Vacuum valve stations (abandoned) ▪ 1 private pump station ▪ Fairway #1 PS (small station) ▪ Fallen Leaf PS #3 ▪ Fallen Leaf PS #4 Exhibit B shows the resulting 25 total pump stations and force mains for review and analysis under this scope of services. Project Scope Based on the Request For Proposal and the District identified needs, Schaaf & Wheeler proposes the following scope of services. Task 1: Data Collection and Review The consultant will gather and review the available provided by the District. This task will rely on the existing knowledge of the District for system as a prelude to any authorized field work by Schaaf & Wheeler. The District will perform the initial field work based on the results of Task 1.2 and at the consultant’s request. Task 1.1: Data Collection and Review Schaaf & Wheeler will review available data, including existing sewer force main as-built drawings, profiles, and operational SCADA data. This includes our review of the District sewer model(s) to additionally identify transient modeling data needs.

DISCUSSION: With the acquisition of the Meyers Water Company and Tahoe Paradise Water Company in the 1960s, the South Tahoe Public Utility Water District was granted six water rights to the Upper Truckee River and a tributary of Saxon Creek. These rights have never been used, and the licensed points of diversion lack infrastructure to divert, treat, and distribute water. Thus, the District seeks to file formal requests to revoke these water rights with the State Water Resources Control Board. The District is currently pursuing a 10,808 acre-foot water right to Lake Tahoe under Water Rights Application No. A023393.

(2) Requests full revocation of these water rights on the grounds that the reservoirs or diversion facilities no longer exist or are incapable of storing or diverting water and no water is used under these rights. (3) Waives Districts hearing and notice rights otherwise required for the processing of the requests for resolution stated herein. (4) Directs Staff to take any and all actions necessary to effectuate the revocation of these water rights.

DISCUSSION: The Bijou 1 Waterline Replacement Project includes two additional bid schedules for As-Needed Services, which allow the District to efficiently address unexpected or high-priority infrastructure needs that arise during construction. The District has successfully used As-Needed bid items in the past to complete critical work with contractors who are already mobilized in the area, even when the work falls outside the specific scope of their primary project. This approach minimizes mobilization costs, shortens response time, and leverages existing contractor resources to address issues before they escalate. The work described in this item is being completed under the As-Needed Services bid schedule and was identified by District field staff based on recent conditions in the system. This project is being brought forward as an unplanned waterline improvement project due to the recent failure history and condition of the existing main. The proposed work includes installing approximately 545 feet of 12-inch C900 waterline along Sacramento Avenue from El Dorado Avenue to Placer Avenue. The work includes replacing two fire hydrants and six domestic water services, as well as two system tie-ins and the abandonment of the existing steel water main. Over the past month, the existing steel water main has experienced five leaks, two of which occurred in an extremely shallow section of pipe. Because of the shallow depth, these connections are exposed to live loading from vehicle traffic and will be further stressed by snow removal equipment this winter. A failure at this location could result in a major leak and flooding of nearby homes on El Dorado Avenue. General Manager Paul Hughes Directors Nick Haven Shane Romsos Joel Henderson Kelly Sheehan Nick Exline Laura Hendrickson Page 2 December 4, 2025 Historical records identify three earlier leaks on this segment; however, staff observed two additional repair bands during recent work, indicating at least ten leaks have occurred on this main. Replacement of the waterline is necessary to address the immediate operational and liability risks and to remove aging steel infrastructure that is not currently included in the 10-year CIP. The anticipated contractor cost for this work is $300,100.

DISCUSSION: After publicly advertising on October 31, 2025, at 10:00 a.m. two bids were received for Sewer Line Spot Repair and Lateral Abandonment Services. Bids were opened on November 24, 2025 at 10:00 a.m. The apparent low bid has been deemed non-responsive for failure to submit the bid documents electronically as required by the Instruction to Bidders. The next lowest responsive bid substantially exceeds the available budget and is not in the best interest of the District to award. No contract award is recommended as rejection of both bids and re-advertising are in the best interest of the District at this time. Re-advertising costs are minimal and within the approved operating budget. The District’s Purchasing Agent has reviewed this item.

As read, bids ranged from $288,875.00 to $814,505. See attachment for the bid tabulation. Bid Review and Determination Robotic Sewer Solutions, Inc. (RSS)- as-read low • Determination: Non-Responsive • Basis: RSS submitted its signed bid documents by mail rather than electronically through PlanetBids, contrary to the solicitation requirement of “electronic submission only” as outlined in the Invitation to Bid and the Instructions to Bidders. This is a material deviation affecting the integrity of the competitive process. The mailed hard-copy has been retained as part of the record.
