Annual Drinking Water Quality Report – 2023Bryce Canyon National ParkWe are pleased to present to you theBryce Canyon National Park 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 the protection of our water resources. We are committed to ensuring the high quality
of your water. Our water sources have been determined to be from ground water under the influence of surface water.The Drinking Water Source Protection Plan for Bryce Canyon National
Park is available for your review. It contains information about source protection zones, potential contamination sources and management strategies to protect our drinking water. Through
our efforts our sources have been determined to have a lowlevel of susceptibility from 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 residences, recreational vehicles, places of work, or stay. 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 across connection. When the cross connectionis 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, contact the Division of Water Quality or call us for further information about ways you
can help.We are pleased to report that our drinking water meets or exceeds federal and state requirements. Our system has had no violations. If you have any questions about this report
or questions concerning our water utility, please contactthe Bryce Canyon Facilities Chief at 435-834-4720 or Buildings and Utilities Foreman at 435-834-4714.We want you our valued customers
to be informed about Bryce Canyon’s water utility.Bryce Canyon National Parkroutinely 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. It also shows the results of monitoring performed for constituents we are
not required to sample for on a yearly basis.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: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.Action Level (AL) - the concentration of a contaminant which, if exceeded,
triggers treatment or other requirements which a water system must follow.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.

Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. Bryce Canyon National Park 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 sampling 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 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.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. 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 strive each day to provide the safest high quality drinking water available. We work continuously to make improvements,
upgrades, and repairs to our systems and infrastructure. Systems are in place to monitor our water quality continuously, so you can rest assured we are meeting this standard. The water
we provide is the first step in making your time spent at Bryce Canyon National Park a safe, rewarding experience.Enjoy our water during your time here, it’s pristine nature and incredible
taste is symbiotic to the beauty of this area.Moyle JohnsonUtilities Systems OperatorBryce Canyon National [e-mail]
