Annual Drinking Water Quality Report 2020
Garden City
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
sources have been determined to be from groundwater sources. Our water sources are Swan Creek
Spring, Payne Spring and Bear Lake Water Company UTAH17010.
The Drinking Water Source Protection Plan for Garden 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 within our water system. However, unapproved connections
and improper plumbing changes can adversely affect the quality of your water. A cross
connection can allow polluted water, fertilizer, or other chemicals to contaminate the water
supply system when not properly protected. Not only can this affect your health, but it can also
damage plumbing and appliances within your property. So, what can you do? Install backflow
preventers at all cross connections within the property.
What does a cross connection look like? The most common cross connection is a landscape
irrigation system. Mud, fertilizer, and waterborne pathogens can be siphoned backwards into the
drinking water if the irrigation system has no backflow preventer. An unprotected garden hose
connected to a fertilizer sprayer, or submerged in a pool or puddle, are also considered cross
connections. When a cross connection is unprotected at your home, it will affect your family or
employees first. If you would like to learn more about preventing backflow at your property, call
us for more information.
I'm pleased to report that our drinking water meets federal and state requirements.
If you have any questions about this report or concerning your water utility, please contact Kathy
Hislop at 435-964-2901. 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 2nd Thursday of every month.
Garden 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, 2020. 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.
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.
3
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. Garden 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.
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.
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
(800-426-4791).
We at Garden 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.
