Annual Drinking Water Quality Report 2023
Dugway-English Village

The Dugway Directorate of Public Works and the Environmental Programs Division is pleased
to present to you the 2023 Annual Drinking Water Quality Report for English Village water
system. This report is designed to inform you about the quality of the water and services we
deliver to you every day. Our 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 for English Village are groundwater sources which we get from
three wells (26, 27 & 30) in English Village.

The Drinking Water Source Protection Plan for the Dugway English Village water system is
available for your review from the Environmental Programs (EP) Office. Please contact Steve
Sheffey at [e-mail] if you have questions about our source protection plan.
It contains information about source protection zones, potential contamination sources and
management strategies to protect our drinking water. Our water sources are in remote, isolated
areas and have very low potential for contamination. We have also developed management
strategies to further protect our sources from contamination and have several trained personnel
on source protection.

There are many connections that can contaminate our water distribution system. When
connections are properly installed and maintained, the concerns are very minimal. However,
unapproved, and improper 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. For example, 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, contact Steve Sheffey at [e-mail] for
further information about ways you can help.

We 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 Steve
Sheffey at [e-mail]. There are no regularly scheduled water quality
meetings at Dugway; however, you are welcome to attend the Dugway town hall meetings when
scheduled for possible updates. If no Environmental Programs Division personnel are in
attendance, submit your questions to Steve Sheffey at [e-mail].

Chenega Facilities Management routinely monitors for constituents in our drinking water in
accordance with the Federal and State of Utah rules and regulations. The following table shows
the results of our monitoring for the period of January 1st to December 31st, 2023.

NOTE: 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 more than 5 NTUs 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.

3
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 the 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.

While your drinking water meets EPA's standard for arsenic, it does contain low levels of
arsenic. EPA's standard balances the current understanding of arsenic's possible health effects
against the costs of removing arsenic from drinking water. EPA continues to research the health
effects of low levels of arsenic which is a mineral known to cause cancer in humans at high
concentrations and is linked to other health effects such as skin damage and circulatory
problems.
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. US Army Dugway
Proving Ground 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 [phone]) 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 and the Utah Division of
Drinking Water 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 man-made. Those constituents can be microbes, organic or inorganic
chemicals, or radioactive materials. As stated earlier, 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 EPA’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 EPA’s Safe Drinking Water Hotline (800-
426-4791). The responsible personnel at Dugway work tirelessly to provide quality drinking
water to every tap. We ask that all customers help us protect our water sources, which are the
heart of our community, our way of life and our children’s future.
