2024 Consumer Confidence Report
2024 Annual Drinking Water Quality Report
High Valley Water Co.

High Valley Water Co. is pleased to present you, our customer, with the most current 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. If you have any questions about this report or concerning your water utility, please contact Justin
Rametta 435-645-8415. 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 fourth
Tuesday of each month at the Basin Recreation Fieldhouse at 7:00 PM.

High Valley Water Company Water Sources:High Valley Water Co. provides its consumers with
ground/surface water. Our water sources include High Valley Old Well, UTAH22059 Summit Water
Distribution, UTAH22137 Mountain Regional SSD.

Source Protection Plan
The Drinking Water Source Protection Plan for High Valley Water Co. 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 sources such as septic systems and roads. 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.

Check for Cross Connections
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.

High Valley Water Co. routinely monitors contaminants in our drinking water in accordance with the
Federal and Utah State laws. The following table shows the results of our monitoring for 2024. It is
important to remember that all water sources of drinking water contain some naturally occurring
contaminants. At low levels, these substances are generally not harmful in our drinking water. Removing
all contaminants would be extremely expensive, and in most cases, would not provide increased
protection of public health.

2024 Consumer Confidence Report
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.

N/A – information not available

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.
2024 Consumer Confidence Report

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.

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.

Why are there contaminants in my drinking water?
Drinking water, including bottled water, may reasonably be expected to contain at least a small amount
of some contaminants. To ensure that tap water is safe to drink, EPA prescribes regulations that limit the
amount of certain contaminants in water provided by public water systems. Food and Drug
Administration (FDA) regulations establish limits for contaminants in bottled water which must provide
the same protection for public health.

The presence of contaminants does not necessarily indicate that the water poses a health risk. More
information about contaminants and the potential health effects can be obtained by calling the
Environmental Protection Agency’s (EPA) Safe Drinking Water Hotline at (800-426-4791). The sources of
drinking water (both tap and bottled water) include rivers, lakes, streams, reservoirs, springs and wells.
As water travels over the surface of the land or through the ground, it dissolves naturally occurring
minerals and, in some cases, radioactive material, and can pick up substances resulting from the
presence of animals or from human activity.

Contaminants that may be present in source water include:
(A) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment
plants, septic systems, agricultural livestock operations and wildlife.
(B) Inorganic contaminants, such as salts and metals, which can be naturally occurring or result
from urban storm water runoff, industrial or domestic wastewater discharge, oil and gas
production, mining, or farming.
(C) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban
storm water runoff and residential uses.
(D) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are
by-products of industrial processes and petroleum production, and can also come from gas
stations, urban storm water runoff and septic systems.
(E) Radioactive contaminants, which can be naturally occurring or be the result of oil and gas
production and mining activities.

2024 Consumer Confidence Report
Information About LeadLead 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. High Valley 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 High Valley Water Company by calling 435-645-8415 or emailing
[e-mail]. 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.

High Valley 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. This inventory is
publicly available and can be accessed by contacting Justin Rametta at [e-mail]
High Valley Water Company has determined that all service lines are non-lead.

If present, elevated levels of lead can cause serious health problems, especially for pregnant women
and young children. Exposure to lead in drinking water can cause serious health eƯects in all age groups.
Infants and children can have decreases in IQ and attention span. Lead exposure can lead to new
learning and behavior problems or exacerbate existing learning and behavior problems. The children of
women who are exposed to lead before or during pregnancy can have increased risk of these adverse
health eƯects. Adults can have increased risks of heart disease, high blood pressure, kidney or nervous
system problems.
High Valley Water Co. has conducted 10 lead samples during a 3 year period. Sampling results can be
obtained by calling 435-645-8415 or emailing [e-mail]. You can also view the
results online at www.highvalleywater.com. We will be conducting this sampling again this summer
2025, please contact us if you’d like to participate.

Attention Immunocompromised Persons
Some people may be more vulnerable to contaminants in drinking water than the general population.
Immunocompromised people such as people with cancer undergoing chemotherapy, people 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 High Valley Water Co. 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.
