2023

1 Huntsville Town Water System 2023 Annual Consumer Confidence Report
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 sour ces have been determined to
be from groundwater sources. Our water sources are Bennett Springs, Virgil Peterson Springs, and Lower Bennett
Springs. These sources are considered groundwater under the influence of surface water. Our other water source
is the Wishing Well. This source is a ground water source. This is the source that we are currently using.
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 Angie Jones at 801-745-3420. 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 and third Thursday of each month at 6:00 p.m.

SOURCE PROTECTION
The Drinking Water Source Protection Plan for Huntsville Town Water System 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 are in remote and protected areas and have a low level of
susceptibility to 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.

PROTECTING THE QUALITY OF YOUR WATER
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 in your homes. 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.

WATER QUALITY DATA AND INFORMATION
Huntsville Town Water System 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, along with the most recent monitoring from previous years. All drinking water,
including bottled drinking water, may be reasonably expected to contain at least small amounts of some
constituents. It is important to remember that the presence of these constituents does not necessarily pose a
health risk.

IMPROTANT DRINKING WATER DEFINITIONS
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 have 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

2 Huntsville Town Water System 2023 Annual Consumer Confidence Report
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.
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.

CONTAMINANTS
Microbiological Contaminants:
Total Coliform. Coliforms are bacteria that are naturally present in the environment and are used as an indicator
that other, potentially harmful, bacteria may be present. Coliforms were found in more samples than allowed and
this was a warning of potential problems.
Fecal coliform/E.coli. Fecal coliforms and E. coli are bacteria whose presence indicates that the water may be
contaminated with human or animal waste. Microbes in these wastes can cause short-term effects, such as
diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young
children, and people with severely compromised immune systems.

5 Huntsville Town Water System 2023 Annual Consumer Confidence Report
Turbidity. Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium
for microbial growth. Turbidity may indicate the presence of disease-causing organisms. These organisms include
bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated
headaches.
Radioactive Contaminants:
Combined Radium 226/228. Some people who drink water containing radium 226 or 228 in excess of the MCL over

Inorganic Contaminants:
Cadmium. Some people who drink water containing cadmium in excess of the MCL over many years could
experience kidney damage.
Carbon, Total Organic (TOC). Carbon, Total Organic (TOC) has no health effects. However, total organic carbon
provides a medium for the formation of disinfection by products. These byproducts include trihalomethanes
(THMs) and haloacetic acids (HAAs). Drinking water containing these byproducts in excess of the MCL may lead to
adverse health effects, liver or kidney problems, or nervous system effects, and may lead to an increased risk of
getting cancer.
Chromium. Some people who use water containing chromium well in excess of the MCL over many years could
experience allergic dermatitis.
Copper. Copper is an essential nutrient, but some people who drink water containing copper in excess of the

IMPORTANT HEALTH INFORMATION
Inadequately treated water may contain disease-causing organisms. These organisms include bacteria,
viruses, and parasites, which can cause symptoms such as nausea, cramps, diarrhea, and associated headaches.
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. Huntsville Town Water System 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: [phone].
We at Huntsville Town Water System 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.

VIOLATIONS
Important Information About Your Drinking Water
Reporting Requirements Not Met for Huntsville Town Water System
Or water system was recently cited for a violation. Even though this was not an emergency and there was no safety
issue involved, as our customers, you have a right to know what happened and what we did to correct the
problem.
We are required to monitor your drinking water for specific contaminants and disinfectant (chlorine) residual on a
regular basis. Results of regular monitoring are an indicator of whether or not our drinking water meets health
standards. During a two-day period in August 2023, August 5th and 13th, our chlorine monitoring system failed to
report the disinfectant residual at the entry point to the distribution system at our water treatment plant.

What should I do?
There is nothing you need to do. We are required to monitor chlorine and report the daily minimum residual. We
were unable to do so for these two days in August 2023 due to the chlorine monitoring equipment malfunction
from power loss.

What happened? What is being done?
The malfunction with the chlorine monitoring system was repaired and tested. Testing indicated that at no time
during the non-monitored period was the disinfectant level below State standards. We resumed regular reporting
on August 14, 2023. For more information, please contact Shannon Smith, Huntsville Town Water Department,
801 745-3420 or via email at [e-mail]
Please share this information with all other people who drink this water, especially those who may not receive this
notice directly. We will do our best to inform all water customers.
This notice is being sent to you by the Huntsville Town Water Department, Water System ID# UTAH29007.
