Annual Drinking Water Quality Report
-2024-
Gunlock Special Service District
We're 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. One of our water sources is a
spring located one mile above town in the Santa Clara Drainage. Our second water source is a
well located within the Gunlock City Limits.
The Drinking Water Source Protection Plan for The Gunlock Special Service District 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 to potential contamination from
sources such as septic tanks and roads. 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
Judy Leavitt at 435-574-8500.
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 first
Wednesday of February, April, June, September, November and December at 7:00 p.m. in
The Gunlock Town Hall.
The Gunlock Special Service District 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, 2024. All drinking water, including
bottled drinking water, may be reasonably expected to contain at least small amounts of some
2
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.
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.
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 out-dated.
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.

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.
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.
While your drinking water meets EPA's standard for arsenic, it does contain low levels of
arsenic. EPA's standard balances the current understanding of arsenic's possible health effects
against the costs of removing arsenic from drinking water. EPA continues to research the health
effects of low levels of arsenic which is a mineral known to cause cancer in humans at high
concentrations and is linked to other health effects such as skin damage and circulatory
problems.
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. The Gunlock Special
Service District 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.
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, 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 The Gunlock Special Service 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.
