2023 Annual
Little Mountain Testing Facility
PWS ID: UT29118
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.

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 801-695-9786
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 facility 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.

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.
Drinking water delivered to Little Mountain by Weber Basin Water Conservancy District may contain naturally-
occurring fluoride from groundwater sources. American Water does not add fluoride to the water system. If you
have any questions on fluoride, please contact us at (801) 695 -9785 or [e-mail].
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.

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.

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.

NOTE: Coliforms are bacteria that are naturally present in the environment and are used as an indicator of the general bacteriol ogical quality of the water. We are reporting the highest
percentage of positive samples / highest number of positive samples in any month.
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.12
American Water Military Service Group – Hill AFB conducts extensive monitoring to determine if your water meets all water quality standards. The detections of our monitoring 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 Used in This Report” on the previous page.
HOW TO READ THIS TABLE (FROM LEFT TO RIGHT)
•Starting with Substance (with units), read across.
•Year Sampled is usually in 2023, but may be a prior year.
•A Yes under Compliance Achieved means the amount of the substance met government requirements.
•MCLG/MRDLG is the goal level for that substance (this may be lower than what is allowed).
•MCL/MRDL/TT/Action Level shows the highest level of substance (contaminant) allowed.
•Highest, Lowest or Average Compliance Result represents the measured amount detected.
•Range tells the highest and lowest amounts measured.
•Typical Source tells where the substance usually originates.
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.

PFAS
American Water performed voluntary sampling in 2020 to better understand the occurrence of certain PFAS in drinking water source s. This sampling allows us to
understand how our water compares against the non-enforceable Health Advisory Level set by U.S. EPA. Sampling also allows American Water to be better prepared
as U.S. EPA is currently developing drinking water standards for PFOA and PFOS.
UNREGULATED PERFLUORINATED COMPOUNDS
Parameter Units Average Result Range Detected Typical Source
Perfluorooctanoic Acid (PFOA)ppt ND ND Manufactured chemical(s); used in household goods for stain,
grease, heat and water resistance
Perfluorooctanesulfonic Acid (PFOS)ppt ND ND
PFAS are not regulated in Utah. In 2022, U.S. EPA set health advisory levels for four PFAS chemicals – PFOA (0.004 part per trillion (ppt)), PFOS (0.02 ppt),GenX (10
ppt), and PFBS (2,000 ppt). Based on current analytical methods, however, the health advisory levels for PFOA and PFOS are below the level of both detection
(determining whether or not a substance is present) and quantitation (the ability to reliably determine how much of a substance is present). This means that it is possible
for PFOA or PFOS to be present in drinking water at levels that exceed health advisories even if testing indicates no level of these chemicals. U.S. EPA is currently
developing drinking water regulations for PFOA and PFOS that take these challenges into consideration and American Water will take appropriate actions to meet any
new regulations. Finally, 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. For more information on PFAS, please visit https://www.epa.gov/pfas.
