Quality on Tap Report Water Quality ReportAnnual Drinking Water Quality ReportThe Water We DrinkCity of North Salt Lake WaterThis report is provided for City of North Salt Lake Water
customers covering the period of January 1 – December 31, 2024. South Davis Water District customers will have access to a similar report from that agency.We are pleased to present this
year’s Annual Drinking Water Quality Report. This report is intended to provide you with important information about the quality of the water and the services we deliver to you each
day. Our ongoing objective is to provide a safe and reliable supply of drinking water. We want you to be informed about the steps we take to continually enhance our water treatment processes
and to protect our valuable water resources. We remain fully committed to ensuring the highest quality of your drinking water.Our water supply comes from surface water sources, including
deep-water wells and water purchased from the Weber Basin Water Conservancy District. For more detailed information, you may request a copy of the Weber Basin Water Conservancy District’s
Annual Water Quality Report by contacting their office at:Weber Basin Water Conservancy District2837 E Highway 193Layton, UT 84041Phone: [phone]Additionally, the Drinking Water
Source Protection Plan for The City of North Salt Lake is available for your review. This document outlines our source protection zones, identifies potential sources of contamination,
and details the management strategies in place to safeguard our drinking water. Our water sources have been assessed as having a low susceptibility to potential contamination. Nonetheless,
we have implemented proactive strategies to further enhance the protection of our water sources.If you have any questions or concerns regarding the Source Protection Plan, please do
not hesitate to contact us.Preventing Cross Connections in Our Water SystemThere are many connections throughout our water distribution system. When these connections are properly installed
and maintained, the risk of contamination is minimal. However, unapproved or improper piping changes and connections can negatively impact both the availability and quality of our water
supply. One significant concern is cross connections—points where non-potable water or other substances can enter the drinking water system due to backflow.Backflow occurs when water
flows in the opposite direction than intended, potentially drawing contaminated water into the clean water supply. This can happen during events such as a sudden drop in water pressure—for
example, when firefighters use a hydrant or a water main breaks.Cross connections can pose a serious health risk. For example, an unprotected garden hose left in a puddle, or a lawn
sprinkler system used after applying fertilizer or pesticides, can allow pollutants or chemicals to enter the drinking water supply. These seemingly minor oversights can compromise water
quality and pose a threat to your health and the health of your family.To help protect our water system, avoid making or allowing improper connections at your home. If you have any questions
or would like more information on how to prevent cross connections and support the safety of our water supply, please contact us. We are here to help and appreciate your cooperation
in keeping our water safe.I'm pleased to report that our drinking water meets federal and state requirements.If you have any questions about this report or concerning your water utility,
please contact Jon Rueckert at 801-335-8727.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 held on first and third Tuesday of the month at City Hall (10 East Center Street).
Water Quality Monitoring and Reporting
The City of North Salt Lake routinely monitors the constituents in our drinking water as required by federal and Utah State regulations. The following table presents the results of our
water quality monitoring conducted from January 1 through December 31, 2024.
It is important to note that all drinking water, including bottled water, may reasonably be expected to contain at least trace amounts of some substances. The presence of these constituents
does not necessarily indicate a health risk. Our goal is to provide you with accurate and transparent information so you can be confident in the safety and quality of your drinking water.
To help you better understand the data in the following table, we have included definitions and explanations of commonly used terms and abbreviations.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.

cause damage to the brain and kidneys and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants,
young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected
by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother’s bones,
which may affect brain development.Sources of Lead Drinking water is one possible source of lead exposure due to the widespread use of lead in plumbing materials. Lead can also be found
in certain types of pottery, pewter, food, and cosmetics. Lead and copper in drinking water most often comes from water distribution lines or household plumbing rather than from the
water system source. Lead can enter drinking water when pipes, solder, home/building interior plumbing, fittings and fixtures that contain lead corrode. Homes built before the 1960s
are more likely to have lead connections on service lines, lead pipes, fixtures, and/or solder that contain lead. Galvanized plumbing can be a potential source of lead. Galvanized plumbing
can absorb lead from upstream sources and can continue to release lead into drinking water over time. Some plumbing products such as service lines, pipes and fixtures may contain lead.
The infographic below demonstrates where sources of lead in drinking water could be in your home. Older homes may have more lead unless the service line and/or plumbing has been replaced.
Homes built… Before the 1960s are more likely to have lead connections on service lines, lead pipes, fixtures, and/or solder that contain lead. Before 1988 are likely to have fixtures
and/or solder that contains lead. Between 1996 and 2014 are likely to have fixtures that contain up to eight percent lead but were labelled “lead-free.” In 2014 or later still have potential
lead exposure. “Lead free” was redefined to reduce lead content to a maximum of 0.25 percent lead in fixtures and fittings. Fixtures that are certified to meet NSF Standard 61 meet this
more restrictive definition of “lead free.” Steps You Can Take to Reduce Your Exposure to Lead in Your WaterRun your water to flush out lead. The more time water has been sitting in
your home’s pipes, the more lead it may contain. Therefore, if your water has not been used for several hours, run the water before using it for drinking or cooking. This flushes lead-containing
water from the pipes. Additional flushing may be required for homes that have been vacant or have a longer service line. Everyone can consider using a filter to reduce lead in drinking
water. Look for filters that are tested and certified to NSF/ANSI Standard 53 for lead reduction and NSF/ANSI Standard 42 for particulate reduction. Some filter options include a pour-through
pitcher or faucet-mount systems. If the label does not specifically mention lead reduction, check the Performance Date Sheet included with the device. Be sure to maintain and replace
the filter device in accordance with the manufacturer’s instructions.Use cold water for drinking and cooking. Do not cook with or drink water from the hot water tap, lead dissolves more
easily into hot water. Do not boil water to remove lead. Boiling water will not reduce lead levels. Identify older plumbing fixtures that likely contain lead. Older faucets, fittings,
and valves sold before 2014 may contain higher levels of lead, even if marked “lead free.” When purchasing new plumbing materials, it is important to look for materials that are certified
to meet NSF standard 61. The EPA prepared a brochure that explains the various markings that can indicate that materials meet the new “lead free” definition: https://nepis.epa.gov/Exe/ZyPDF.cgi?Dockey=P100LVYK.txt.
Clean your aerator. The aerator on the end of your faucet is a screen that will catch debris. This debris could include particulate lead. Test your water for lead. Call us at 801-335-8726
to find out additional information on how to get your water tested for lead. Testing can be completed by a certified laboratory for a cost. All sources of drinking water are subject
to potential contamination by constituents that are naturally occurring or man-made. Those constituents can be microbes, organic or inorganic chemicals, or radioactive materials. All
drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate
that the water poses a health risk. 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. Immunocompromisedpeople 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 atthe City of North Salt Lake 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 future. You may also contact City Staff member below for more informationCarmen Wilson, Public Works Admin(801) [e-mail]
