Annual Drinking Water Quality Report
Cornish Town Water System 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 source comes from Griffith
Spring, Pearson Spring, Pitcher Well, and Gancheff Well.
The Drinking Water Source Protection Plan for Cornish Town 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 from sources that are remote and protected. 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 Matt Leak at 435-757-6726. 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 the third Thursday of each month.
Cornish Town 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, 2022. 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.
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. Cornish
Town 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 Cornish Town 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.

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.
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 outdated.
