Quality on Tap Report Water Quality ReportAnnual Drinking Water Quality ReportThe Water We DrinkSwiss Oaks Special Service DistrictWe're pleased to present to you this year's Annual
Drinking Water Quality Report. We purchase all of our water from Midway City. This report is designed to inform you about the quality of the water and services delivered to you every
day. The constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts made to continually improve the water treatment process
and protect our water resources. We are committed to ensuring the quality of your water. Our water sources have been determined to be from groundwatersources. Midway’s water sources
are Gerber Spring, Mahogany Spring, Alpenhof Well and Alpenhof -Weber WellThe Drinking Water Source Protection Plan for Midway Water system is available for your review from Midway
City It contains information about source protection zones, potential contamination sources and management strategies to protect our drinking water. Our sources have been determined
to have alowlevel of susceptibility from potential contamination from sources potential contamination sources. We have also developed management strategies to further protect our water
sources from contamination. Please contact us if you have questions or concerns about our source protection plan (435-352-0369).
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 across connection. When the cross connectionis 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.I'm pleased to report that our drinking water meets federal and state requirements.Midway City routinely
monitorsconstituents 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 addition to monitoring for constituents by Midway City,Swiss Oaksroutinely monitors for constituents
in our drinking water in accordance with the Federal and Utah State laws. The following table shows all monitoring results 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. If you have any questions about this report or concerning your water utility, please contact Shane Owens at 435-352-0369.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 the second and fourth Wednesday of each month
beginning at 7:00 PM at 160 West Main Street.In the following table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms
we've provided the following definitions:Non-Detects (ND) - laboratory analysis indicates that the constituent is not present.ND/Low - High - For water systems that have multiple sources
of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish
this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table. Parts per million (ppm) or Milligrams per liter (mg/l) - one
part per million corresponds to one minute in two years or a single penny in $10,000.Parts per billion (ppb) or Micrograms per liter (ug/l) - one part per billion corresponds to one
minute in 2,000 years, or a single penny in $10,000,000. Parts per trillion (ppt) or Nanograms per liter (nanograms/l) - one part per trillion corresponds to one minute in 2,000,000
years, or a single penny in $10,000,000,000.Parts per quadrillion (ppq) or Picograms per liter (picograms/l) - one part per quadrillion corresponds to one minute in 2,000,000,000 years
or one penny in $10,000,000,000,000.Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.Millirems per year (mrem/yr) - measure of radiation
absorbed by the body.Million Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers.Nephelometric Turbidity
Unit (NTU) - nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.Action Level (AL) - the concentration
of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.Treatment Technique (TT) - A treatment technique is a required process
intended to reduce the level of a contaminant in drinking water.Maximum Contaminant Level (MCL) - The “Maximum Allowed” (MCL) is the highest level of a contaminant that is allowed in
drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.Maximum Contaminant Level Goal (MCLG) - The “Goal”(MCLG) is the level of
a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.Maximum Residual Disinfectant Level (MRDL) - The highest
level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.Maximum Residual Disinfectant
Level Goal (MRDLG) - The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants
to control microbial contaminants. Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem outdated.Waivers (W)- Because some
chemicals are not used or stored in areas around drinking water sources, some water systems have been given waivers that exempt them from having to take certain chemical samples, these
waivers are also tied to Drinking Water Source Protection Plans.

InJune 2023 we failed to test for coliform bacteria. Water quality may change without any visible indication due to unanticipated environmental factors. For this reason, we are required
to sample coliform bacteria on a monthly basis. This violation does not necessarily pose a health risk.We have reviewed why we failed to take our routine coliform bacteria tests and
have taken steps to ensure that it will not happen again.Chlorine Residual Monitoring ViolationWe periodically monitor Chlorine Residual in the distribution system to meet all regulatory
requirements. In the third quarter of2023 we failed to take the required samples. Testing for a Chlorine Residual is used to ensure that the public is provided with safe drinking water.
This violation does not necessarily pose a health risk.We have reviewed why we failed to take the required samples and will take steps to ensure that it will not happen again.
Microbiological Contaminants:
Total Coliform. Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially harmful, bacteria may be present. Coliforms
were found in more samples than allowed and this was a warning of potential problems.
Fecal coliform/E.Coli. Fecal coliforms and E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can
cause short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, and people with severely compromised
immune systems.
Turbidity. Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may indicate the presence of disease-causing
organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
Inorganic Contaminants:
Antimony. Some people who drink water containing antimony well in excess of the MCL over many years could experience increases in blood cholesterol and decreases in blood sugar.
Arsenic. Some people who drink water containing arsenic in excess of the MCL over many years could experience skin damage or problems with their circulatory system and may have an increased
risk of getting cancer.

Barium. Some people who drink water containing barium in excess of the MCL over many years could experience an increase in their blood pressure.
Cadmium. Some people who drink water containing cadmium in excess of the MCL over many years could experience kidney damage.
Copper. Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal
distress. Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson's disease should consult
their personal doctor.
Fluoride. Some people who drink water containing fluoride in excess of the MCL over many years could get bone disease, including pain and tenderness of the bones. Children may get mottled
teeth.
Lead. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits
in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.
Nitrate. Infants below the age of six months who drink water containing nitrate in excess of the MCL could become seriously ill and, if untreated, may die. Symptoms include shortness
of breath and blue-baby syndrome.
Nitrite. Infants below the age of six months who drink water containing nitrite in excess of MCL could become seriously ill and, if untreated, may die. Symptoms include shortness of
breath and blue-baby syndrome.
Selenium. Selenium is an essential nutrient. However, some people who drink water containing selenium in excess of the MCL over many years could experience hair or fingernail losses,
numbness in fingers or toes, or problems with their circulation.
Sodium. Sodium is an essential nutrient. However, some people who drink water containing sodium in excess of MCL may experience health problems.
Sulfate. High levels of sulfates in drinking water may cause some people to have stomach problems.
TDS (Total Dissolved Solids). TDS is an aesthetic water quality problem; however high levels may cause some people to experience health problems.
Synthetic organic contaminants including pesticides and herbicides:
Toluene. Some people who drink water containing toluene well in excess of the MCL over many years could have problems with their nervous system, kidneys, or liver.
Xylenes. Some people who drink water containing xylenes in excess of the MCL over many years could experience damage to their nervous system.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.
Midway City 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 http://www.epa.gov/safewater/lead.As you can see from 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. 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. 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]).
