Annual Drinking Water Quality Report 2024
Willow Creek Water Company UTAH02062

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 the Willow Creek Well and Willow Creek Well #2.

The Drinking Water Source Protection Plan for Willow Creek Water Company 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 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 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 the operator, Andrew Beecher, at 435-230-9658.
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 an as needed basis. Meeting notifications
can be found on our website, willowcreekwatercompany.com.

Willow Creek Water Company 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, 2024, to December 31st, 2024. 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.

I'm pleased to report that our drinking water meets federal and state requirements.

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:

2
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.

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
3
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.

4
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.

We periodically monitor for Disinfection By-Products in the distribution system to meet all regulatory
requirements. In 2024 we failed to take the required samples. Testing for a Chlorine Residual is used to ensure
that the public is provided with safe drinking water. This violation does not necessarily pose a health risk. We
have reviewed why we failed to take the required samples and will take steps to ensure that it will not happen
again.

Willow Creek Water Company has completed an initial lead service line inventory. This inventory includes
information on the service line material that connects water mains to buildings/houses. Willow Creek Water
Company determined that all service lines are non-lead. For more information on this service line inventory,
please contact the operator, Andrew Beecher, at 435-230-9658.

Five lead samples were collected during 2022. Sampling results can be obtained by calling or texting 435-230-
9658 or emailing [e-mail].

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. Willow
Creek Water Company is responsible for providing high quality drinking water and removing lead pipes, but
cannot control the variety of materials used in plumbing components in your home. 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. Before drinking tap water, flush your pipes for several minutes by running your tap,
taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National
Standards Institute accredited certifier to reduce lead in drinking water. If you are concerned about lead in
your water and wish to have your water tested, contact our operator, Andrew Beecher at 435-230-9658.
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.

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
5
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 Willow Creek Water Company 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.
