Annual Drinking Water Quality Report
Midway City 2023
We 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.
Our constant goal is to provide you with a safe and dependable supply of drinking water. We want
you to understand the efforts we make to continually improve the water treatment process and
protect our water resources. We are committed to ensuring the quality of your water. Our water
source(s) have been determined to be from groundwater sources. Our water source is Gerber
Spring, Mahogony Spring, Alpenhof Well, Alpenhof – Weber Well.
The Drinking Water Source Protection Plan for Midway City is available for your review. 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 a
low level of susceptibility from potential contamination. We have also developed management
strategies to further protect our sources from contamination. Please contact us if 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 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 Tuesday of each month beginning at 7:00 p.m. at 160 West Main Street
in Midway, Utah.
Midway City routinely monitors for 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.
2
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
3
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.

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 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.
Acute (Code 21)
Water samples taken in June 2023 confirmed the presence of fecal coliforms or Escherichia coli.
5
The presence of fecal coliforms and E. coli in drinking water is serious because it is associated
with sewage or animal wastes and can cause disease. The presence of this bacteria in our system
was a result of an unknown source. Disease symptoms include diarrhea, cramps, nausea, and
possible jaundice, and associated headaches and fatigue. When the June 2023 samples confirmed
the presence of fecal coliforms and E. coli we took steps to identify and correct the problem.
Subsequent monthly sampling has confirmed the absence of fecal coliforms and E. coli in the water
system.
Non-Acute (Code 22)
Water samples taken in June 2023 confirmed the presence of total coliform bacteria. Total
coliforms are common in the environment and are generally not harmful themselves. The presence
of these bacteria is usually a result of a problem with water treatment or the pipes which distribute
the water and indicates that the water may have been contaminated with organisms that can cause
disease. Symptoms may include diarrhea, cramps, nausea, and possible jaundice, and any
associated headaches and fatigue. When the monthly samples confirmed the presence of total
coliform bacteria, we took steps to identify and correct the problem. Subsequent monthly sampling
has confirmed the absence of total coliforms in the water system.
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,
6
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 at Midway City 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 children’s future.
