Annual Drinking Water Quality Report
The Water We Drink
Thatcher-Penrose Service
2024
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 source(s) have
been determined to be from Groundwater sources. Our water source is 2 wells and the Bear River
Water Conversancy District.

The Drinking Water Source Protection Plan for Thatcher-Penrose 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 such as septic tanks, roads,
residential areas, industrial areas, etc. 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 Randy
Nelson at 435-466-0451. 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
second Tuesday each month at 6 pm.
Thatcher Penrose 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 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.
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 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.
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. Thatcher Penrose 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.
Immuno-compromised 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 Thatcher Penrose 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.
