2024 Annual Drinking Water Quality Report
Mount Pleasant

Mount Pleasant is pleased to present you, our customer, with the most current 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. If you
have any questions about this report or concerning your water utility, please contact Colter T. Allen 435-
462-2456. 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 city council meetings. They are held on 2nd and 4th
Tuesdays of the month at 6:30 pm.

Mount Pleasant provides its consumers with ground water. Our water sources include 3 wells & 2
springs.
Corrosion of pipes, plumbing fittings and fixtures may cause lead and copper to enter drinking water. To
assess corrosion of lead and copper, Mount Pleasant conducts tap sampling for lead and copper at 20
selected sites every 3 years. Mount Pleasant treats water using ti 2906 Phosphate, perisatltic pumped
into the main spring line to control corrosion, which was designated as the optimal corrosion control
treatment by Utah. To ensure the treatment is operating effectively, Mount Pleasant monitors water
quality parameters set by Utah.
Mount Pleasant has completed an initial lead service line inventory. This inventory includes information
on the service line material that connects water mains to buildings/houses. These inventory reports are
publicly available and can be accessed at

The Drinking Water Source Protection Plan for Mount Pleasant 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 sources. 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
2024 Consumer Confidence Report
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.

Mount Pleasant routinely monitors contaminants in our drinking water in accordance with the Federal
and Utah State laws. The following table shows the results of our monitoring for 2024. It is important to
remember that all water sources of drinking water contain some naturally occurring contaminants. At
low levels, these substances are generally not harmful in our drinking water. Removing all contaminants
would be extremely expensive, and in most cases, would not provide increased protection of public
health.

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.
2024 Consumer Confidence Report

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.

2024 Consumer Confidence Report
Why are there contaminants in my drinking water?

Drinking water, including bottled water, may reasonably be expected to contain at least a small amount
of some contaminants. The presence of contaminants does not necessarily indicate that the water
poses a health risk. More information about contaminants and the potential health effects can be
obtained by calling the Environmental Protection Agency’s (EPA) Safe Drinking Water Hotline at (800-
426-4791). The sources of drinking water (both tap and bottled water) include rivers, lakes, streams,
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 contaminates,
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, which 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, which may come from
a variety of sources such as agricultural, urban stormwater runoff, and residential uses; organic
chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of
industrial processes and petroleum production, and can also come from gas stations, urban stormwater
runoff, and septic systems; and radioactive contaminants, which can be naturally occurring or be the
result of oil and gas production and mining activities. To ensure that tap water is safe to drink, EPA
prescribes 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.

If present, lead can cause serious health problems, especially for pregnant women and young children.
Mount Pleasant has conducted 20 lead samples during a 3 year period. Sampling results can be
obtained by calling Colter T. Allen 435-462-2456 or emailing [e-mail] or visiting
www.mpcityut.gov

Mount Pleasant is responsible for providing high quality drinking water but cannot control the variety of
materials used in plumbing components. Lead in drinking water is primarily from material and
components associated with service lines and home plumbing. You share the responsibility for
protecting yourself and your family from the lead in your home plumbing. You can take responsibility by
identifying and removing lead materials within your home plumbing and taking steps to reduce your
family's risk. If 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. You
can also use a filter certified by an American National Standards Institute accredited certifier to reduce
lead in drinking water. 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. If you are concerned about lead in your water, you may wish to have your
water tested. Please contact Colter T. Allen 435-462-2456. Information on lead in drinking water, testing
methods, and steps you can take to minimize exposure is available at
http://www.epa.gov/safewater/lead.

Some people may be more vulnerable to contaminants in drinking water than the general population.
Immunocompromised people such as people with cancer undergoing chemotherapy, people 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
2024 Consumer Confidence Report
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 Mount Pleasant 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.
