,4nnua/ Drinking Water Quality Report
Elk Ridge City
2023
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 sources. Our water sources are
Cloward Well (#4), Loafer Canyon Well (#7), and Skyhawk Well (#9).
The Drinking Water Source Protection Plan for Elk Ridge 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 are located 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.
Source Water Protection Tips
Protection of drinking water is everyone's responsibility. You can help protect your
community's drinking water source in several ways: * Eliminate excess use of lawn and
garden fertilizers and pesticides - they contain hazardous chemicals that can reach your
drinking water source. * Pick up after your pets. * If you have your own septic system,
properly maintain your system to reduce leaching to water sources or consider connecting
to a public water system. * Dispose of chemicals properly; take used motor oil to a recycling
center. * Volunteer in your community. Find a watershed or wellhead protection
organization in your community and volunteer to help. If there are no active groups,
consider starting one. Use EPA's Adopt Your Watershed to locate groups in your
community or visit the Watershed Information Network's How to Start a Watershed Team.
* Organize a storm drain stenciling project with your local government or water supplier.
Stencil a message next to the street drain reminding people "Dump No Waste - Drains to
River" or "Protect Your Water." Produce and distribute a flyer for households to remind
residents that storm drains dump directly into your local water body.
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 liose 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.
Cross Connection Control Survey
The purpose of this survey is to determine whether a cross-connection may exist at your
1
home or business. A cross connection is an unprotected or improper connection to a public
water distribution system that may cause contamination or pollution to enter the system.
We are responsible for enforcing cross-connection control regulations and ensuring that no
contaminants can, under any flow conditions, enter the distribution system. If you have any
of the devices listed below, please contact us so that we can discuss the issue, and if needed,
survey your connection and assist you in isolating it if that is necessary. * Boiler/ Radiant
heater (water heaters not included) * Underground lawn sprinkler system * Pool or hot tub
(whirlpool tubs not included) @ Additional source(s) of water on the property * Decorative
pond * Watering trough
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
Jerry Clark at 801-423-2300. 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 and 4'h Tuesday each month at 7:00 pm at 80 East Park Drive, Elk
Ridge, Utah 84651.
Elk Ridge 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 Ist to December 31s', 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:
Non-Detects (ND) - laboratoiy analysis indicates that the constituent is not present.
NDfl,ow - High - For water systems that have multiple sorirces 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.
Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.
Nephelometric TurbidUy 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 ContaminantLevel (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 Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in
2
drinking water. There is convincing evidence tliat addition of a disinfectant is necessary for
control of 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.

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 wastes. 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.
Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six
months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate
levels may rise quickly for shoit periods of time because of rainfall or agricultural activity. If you
are caring for an infant you should ask advice from your health care provider.
Infants and young children are typically more vulnerable to lead in drinking water than the
general population. It is possible that lead levels at your home may be higher than at other homes
in the community as a result of materials used in your home's plumbing. If you are concerned
about elevated lead levels in your home's water, you may wish to have your water tested and
flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is
available from the Safe Drinking Water Hotline [phone]).
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. Elk Ridge 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.

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
contarninants 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 tlie 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 rindergoing
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 Elk Ridge 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.
Water Conservation Tips Did you know that the average U.S. household uses
approximately 400 gallons of water per day or 100 gallons per person per day? Luckily,
there are many low-cost and no-cost ways to conserve water. Small changes can make a big
difference - try one today and soon it will become second nature. * Take short showers - a
5-minute shower uses 4 to 5 gallons of water compared to up to 50 gallons for a bath. *
5
Shut off water while brushing your teeth, washing your hair, and shaving and save up to
500 gallons a month. @ Use a water-efficient showerhead. They're inexpensive, easy to
install, and can save you up to 750 gallons a month. * Run your clothes washer and
dishwasher only when they are full. You can save up to 1,000 gallons a month. * Water
plants only when necessary. * Fix leaky toilets and faucets. Faucet washers are inexpensive
and take only a few minutes to replace. To check your toilet for a leak, place a few drops of
food coloring in the tank and wait. If it seeps into the toilet bowl without flushing, you have
a leak. Fixing it or replacing it with a new, more efficient model can save up to 1,000 gallons
a month. * Adjust sprinklers so only your lawn is watered. Apply water only as fast as the
soil can absorb it and during the cooler parts of the day to reduce evaporation. * Teach your
kids about water conservation to ensure a future generation that uses water wisely. Make it
a family effort to reduce next month's water bill! * Visit www.epa.gov/watersense for more
information.
