We are pleased to present to y'ou this year's Annual Drinking Water Qualrty Report. This report
is designed to inform you about the qualrty 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 sources are ground and surface water and come from Jordan Valley Water
Conservancy District, five wells and one spring.
The Drinking Water Source Protection Plan for Herriman City is available for your review. It
contains information about source protection zones, potential contamination sources and
management strategies to protect our drinking water. Potential contamination sources common
in our protection areas are residential areas. Our sources have a low susceptibility to potential
contamination. We have also developed management strategies to further protect our sources
from contamination. Please contact us if you have questions or concems 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 we 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.
We are pleased to announce that our water meets all federal and state requirements.
If you have any questions about this report or concerning your water utility, please contact Luke
Sieverts at80l-M6-5323. We want our valued customers to be informed about their water
utility. If you want to learn more, please affend any of our regularly scheduled meetings. They
are held on every second and fourth Wednesday of the month at7:00 p.m., However they are
subject to change.
Herriman City routinely 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 I't to December 3l't, 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:
ND/Low - High - For water systems that have multiple sources of water, the Utah Division of
Drinking Water has given wat:r 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 Milligtams per liter (mg/l) - one part per million corresponds to one
minute in two years or a singler penny in $10,000.
Parts per billion (ppb) or Mictrograms 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.
Picocaries 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 concerrtration of a contaminant which, if exceeded, triggers treatment or
other requirements which a warter system must follow.
Moximum Contaminant Leve,l (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 Disinfectwnt 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 contaminzrnts.
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 ofthe use of disinfectants to contol microbial contaminants.
Date- Because of required sanrrpling time frames i.e. yearly, 3 years, 4 years and 6 years,
sampling dates may seem outdated.

Unregulated Contarninant Monitoring Detections (UCMR)
The EPA uses a set of rules called the Unregulated Contaminant Monitoring Rule (UCMR) to
check for substances in drinking water that aren't controlled by existing rules. Unregulated
contaminates are those for which EPA has not established drinking water standards. The purpose
of unregulated contaminant monitoring is to assist EPA in determining the occurrence of
unregulated contaminants in drinking water and whether future regulation is warranted.

Lithium
Lithium is a natural metal that can be found more in certain places, especially in the groundwater
of dry areas in the Westem U.li. People have been using lithium in medicines for a long time to
4
help with certain health issues. Even though we know a lot about using lithium in medicine,
there's not much information about the health risks for people who get small amounts of lithium
from drinking water, which is way less than what's used in medicine. Right now, the
Environmental Protection Agency (EPA) is not sure about the risks for people who have low
levels of lithium in their drinking water. Scientists are still learning about how lithium affects our
health and at what levels it might be a concem.
All sources of drinking water are subject to potential contamination by constituents that are
naturally occurring or are 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 Drirrking Water Hotline at l-8004264791.
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.
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. Herriman 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
Some people may be more vulnerable to contaminants in drinking water than the general
population. Immuno-compromised 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 about drinking water from their health care providers.
EPA/CDC guidelines on apprc,priate means to lessen the risk of infection by cryptosporidium
and other microbiological conlaminants are available from the Safe Drinking Water Hotline
(800-426-4791).
We at Herriman City Municipal Water Deparfinent 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.
