Annual Drinking Water Quality ReportMona CityWe are pleased to present to you this year's Annual Drinking Water Quality Report. This report is designed to inform you about the quality
of the water and services we deliver to you every day. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources.
Our water source isgroundwater from the Upper Clover Spring.The Drinking Water Source Protection Plan forMona Cityis available for your review.It contains information about source protection
zones, potential contamination sources and management strategies to protect our drinking water.Our source is located in a remote and protected area and has a low level of susceptibility
to potential contamination sources.We have also developed management strategies to further protect our source from contamination.Please contact usif 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.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 ChadPhillips 385-204-8334.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 onthe second and fourth Tuesday of the month at 7:00 pm. Mona City Office 20 West Center.Mona Cityroutinely monitors
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. Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.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.

:Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses, and parasites, which can cause symptoms such as nausea, cramps, diarrhea,
and associated headaches.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. Mona Cityis responsible for providing high quality drinking waterbut cannot control the variety of materials
used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before
using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and
steps you can take to minimize exposure is available from the safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.As you can see by the table, our system had no violations.
We’re proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some constituents have been detected.
The EPA has determined that your water IS SAFE at these levels. All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or manmade.Those
constituents can be microbes, organic or inorganic chemicals, or radioactive materials.All drinking water, including bottled water, may reasonably be expected to contain at least small
amounts of some contaminants.The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants and potential health effects
can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791.MCLs are set at very stringent levels. To understand the possible health
effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having
the described health effect.Total Coliform: The Total Coliform Rule requires water systems to meet a stricter limit for coliform bacteria. Coliform bacteria are usually harmless, but
their presence in water can be an indication of disease-causing bacteria. When coliform bacteria are found, special follow-up tests are done to determine if harmful bacteria are present
in the water supply. If this limit is exceeded, the water supplier must notify the public by newspaper, television or radio. To comply with the stricter regulation, we have increased
the average amount of chlorine in the distribution system.Nitrates: As a precaution we always notify physicians and health care providers in this area if there is ever a higher than
normal level of nitrates in the water supply. Lead: Lead in drinking water is rarely the sole cause of lead poisoning, but it can add to a person's total lead exposure. All potential
sources of lead in the household should be identified and removed, replaced or reduced.Some people may be more vulnerable to contaminants in drinking water than the general population.
Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some
elderly, and infants can be particularly at risk from infections. These people should seek advice from their health care providers about drinking water. EPA/CDC guidelines on appropriate
means to lessen the risk of infection by cryptosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline [phone]).We at Mona Citywork
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. Mona City
