Each year, Hill Air Force Base, operated by American Water Operations
and Maintenance LLC, produces a Water Quality Report. For more
information about this report, please contact American Water at 801-
695-9786 or [e-mail].
Once again, we proudly present our Annual Water Quality Report, also referred to as a
Consumer Confidence Report (CCR). CCRs let consumers know what contaminants, if any,
were detected in their drinking water as well as related potential health effects. CCRs also
include details about where your water comes from and how it is treated. Additionally, they
educate customers on what it takes to deliver safe drinking water and highlight the need to
protect drinking water sources.

WHERE YOUR WATER COMES FROM
Drinking water for Hill Air Force Base comes
from groundwater wells located throughout the
installation that pump water from the Delta Aquifer
located several hundred feet below the
installation. We also receive water from Weber
Basin Water Conservancy District (WBWCD) to help
supplement the capacity of the wells.
The Delta Aquifer is considered a “confined” or
“protected” aquifer because of layers of clay that
protect the aquifer from contamination
sources. Surface and shallow aquifer
contamination cannot penetrate the clay layers and
therefore pose less of a threat to the quality of
water used for drinking at Hill AFB.
WBWCD has multiple sources of water including
groundwater wells and Pineview
Reservoir. WBWCD treats the water to drinking
water standards and distributes the water to
multiple communities, including Hill AFB.
Disinfection treatment:
All HAFB water sources are treated with chlorine for
disinfection, phosphate for corrosion control, and
fluoride to reduce dental decay.

WHAT ARE WE DOING?
Our priority is to provide reliable, quality
drinking water service for customers. The
source of supply is an important part of that
mission. We work to understand and reduce
potential risks to your drinking water supply.
We have developed a Drinking Water
Source Protection Plan under the guidance
of the Utah Drinking Water Source
Protection Program. The intent of the
program is to identify and address potential
threats to drinking water supplies.
Stakeholder involvement is an important
part of the program. We partner with the
Hill AFB Environmental office and
participate in the monthly Water Working
Group meetings to review and discuss
activities at Hill AFB that can affect water
quality.

CHECK YOUR PLUMBING AND SERVICE LINE
If you live in an older home, consider having a licensed plumber check your plumbing for
lead. If your service line is made of lead, and you’re planning to replace it, be sure to
contact us at 1-XXX-XXX-XXXX.
7
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.
American Water 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.

PFAS
Per- and polyfluoroalkyl substances (PFAS) are manufactured chemicals used in many household products including
nonstick cookware (e.g., Teflon ), stain repellants (e.g., Scotchgard ), and waterproofing (e.g., GORE-TEX ). They are also
used in industrial applications such as in firefighting foams and electronics production. There are thousands of PFAS
chemicals, and they persist in the environment. Two well-known PFAS chemicals are perfluorooctanoic acid (PFOA) and
perfluorooctane sulfonic acid (PFOS). These were phased out of production in the United States and replaced by
hexafluoropropylene oxide-dimer acid (commonly known as GenX ), perfluorobutane sulfonic acid (PFBS) and others.
American Water and Bio Environmental performed voluntary sampling to better understand occurrence of certain PFAS in
drinking water sources in 2016 and 2020. This sampling allows us to be better prepared as U.S. EPA is currently
developing drinking water standards for six PFAS chemicals – PFOA (4 ppt), PFOS (4 ppt) and GenX , PFBS, PFNA, and
PFHxS as a group using a Hazard Index of 1. For more information on the proposed PFAS drinking water standards, please
visit https://www.epa.gov/pfas.
The science and regulation of PFAS and other contaminants is always evolving, and American Water strives to be a leader
in research and development. PFAS contamination is one of the most rapidly changing areas in the drinking water field. We
have invested in our own independent research, as well as engaging with other experts in the field to understand PFAS
occurrence in the environment. We are also actively assessing treatment technologies that can effectively remove PFAS
from drinking water, because we believe that investment in research is critically important to addressing this issue.
To date, there have been no PFAS chemical found in any of HAFB’s groundwater sources.
UNREGULATED CONTAMINANT MONITORING RULE (UCMR)
EPA created the unregulated contaminant monitoring rule (UCMR) to assist them in determining the occurrence of
unregulated contaminants in drinking water and whether new regulations are warranted (unregulated contaminants are
those for which EPA has not established drinking water standards). The first UCMR testing (UCMR1) was completed in
2003, UCMR2 testing was conducted in 2008 and 2009, UCMR3 in 2013 and 2016, and UCMR4 was completed from
2018 to 2020.
In 2023, our water system sampled for a series of unregulated contaminants as required by EPA’s UCMR5 sampling
rule. The purpose of monitoring for these contaminants is to help EPA decide whether the contaminants should have a
standard. As our customers, you have a right to know that we have performed this sampling and that this data will is
available. If you are interested in examining the results, please contact American Water at 801-695-9786, or by email at
[e-mail], or by mail at P.O. Box 56250, Hill Air Force Base UT, 84056.More information on the UCMR
process, which at this time includes monitoring for 29 PFAS analytes and lithium, is available
at https://www.epa.gov/dwucmr.
The results from the UCMR monitoring are reported directly to EPA and are incorporated in the data tables in this report
as appropriate. For more information, contact us at [phone] or [e-mail] .

CRYPTOSPORIDIUM
Cryptosporidium is a microbial pathogen found in surface
water throughout the U.S. Although filtration removes
Cryptosporidium, the most commonly-used filtration
methods cannot guarantee 100 percent removal. Our
monitoring indicates the presence of these organisms in our
source water and/or finished water. Current test methods
do not allow us to determine if the organisms are dead or if
they are capable of causing disease. Ingestion of
Cryptosporidium may cause cryptosporidiosis, an abdominal
infection. Symptoms of infection include nausea, diarrhea,
and abdominal cramps. Most healthy individuals can
overcome the disease within a few weeks. However,
immuno-compromised people, infants and small children,
and the elderly are at greater risk of developing life-
threatening illness. We encourage immuno-compromised
individuals to consult their doctor regarding appropriate
precautions to take to avoid infection. Cryptosporidium must
be ingested to cause disease, and it may be spread through
means other than drinking water.

NITRATES
Nitrate in drinking water at levels above 10 ppm is a health
risk for infants of less than six months of age. High nitrate
levels in drinking water can cause blue baby syndrome.
Nitrate levels may rise quickly for short periods of time
because of rainfall or agricultural activity. If you are caring
for an infant you should ask advice from your health care
provider.
FLUORIDE
Fluoride is a naturally occurring substance that can be
present in drinking water from two sources:
1.By nature when groundwater contacts fluoride-
containing minerals naturally present in the earth; or
2.By a water purveyor adding fluoride to the water
system.
The HAFB Water System has naturally-occurring fluoride in
the groundwater, but American Water also adds fluoride as
mandated by DoD, and Davis County. American Water
strives to achieve an optimal fluoride level of 0.7 ppm and
within a control range of 0.6 ppm to 0.8 ppm. If you have
any questions on fluoride, please contact us at (801) 695-
9785 or [e-mail] .

WATER QUALITY STATEMENT
We are pleased to report that during calendar
year 2023, the results of testing of your
drinking water complied with all state and
federal drinking water requirements.
For your information, we have compiled a list in
the table below showing the testing of your
drinking water during 2023. The Utah Division
of Drinking Water allows us to monitor for some
contaminants less than once per year because
the concentration of the contaminants does not
change frequently. Some of our data, though
representative, are more than one year old.
1111
American Water conducts extensive monitoring to determine if your water meets all water quality standards. The results of our mo nitoring are reported in the following tables. While most monitoring was conducted in 2023, certain substances are monitored less than once per year because the levels do not change frequently. For help with interpreting the tables below, see the “Definition of Terms” on the previous page. Some unregulated substances are measured, but maximum contaminant levels have not been established by the government. These contaminants are shown for your information.
NOTE: Regulated contaminants not listed in this table were not found in the treated water supply.

1 The Treatment Technique for Total Coliforms requires that if the maximum percentage OR number of total coliform positive samples are exceeded a system assessment must be
conducted, any sanitary defects identified, and corrective actions completed. Additional Level 1 Assessments or Level 2 Assessments are required depending on the circumstances.
2 The Treatment Technique for E. Coli requires that for any total coliform positive routine sample with one or more total colif orm positive check samples and an E. coli positive result for any
of the samples a Level 2 Assessment must be conducted, any sanitary defects identified, and corrective actions completed. The E. Coli MCL is exceeded if routine and repeat samples are
total coliform-positive and either is E. coli-positive, or the system fails to take repeat samples following an E. coli-positive routine sample, or the system fails to analyze total coliform-positive
repeat samples for E. coli.

PFAS chemicals are unique, so two PFAS chemicals at the same level typically do not present the same risk. Therefore, you should not compare the results for
one PFAS chemical against the results of another.
UNREGULATED CONTAMINANT MONITORING RULE
Unregulated contaminants are those for which the EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to
assist the EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is necessary. Every five years, the EPA
issues a new list of no more than 30 unregulated contaminants to be monitored. If you are interested in examining the results, please contact American Water at 801-
695-9786 or [e-mail]. The table below provides information on the unregulated contaminants that were detected in the water system under the current
round of monitoring.
