2018 CLEAN WATER CONSUMER CONFIDENCE REPORT
BACKGROUND:
In accordance with the California Code of Regulations (Title 22, Chapter 15, Article 20) and
California Health and Safety Code (HSC, section 116470), all community water systems must
prepare and distribute a Consumer Confidence Report (CCR) before July 1 of each year. The
2018 Azusa Light & Water (ALW) Clean Water CCR contains water quality data from
January 1, 2018 through December 31, 2018, and it shows that ALW's water is of superior
quality and much cleaner than that required by State and Federal regulations. The CCR includes
information on the source of water, levels of detected contaminates, if any, and compliance with
drinking water regulations. The 2018 Clean Water CCR has been distributed to all AL W
customers via a mailed bill insert and posting of the report on the City website. AL W has
satisfied its compliance obligations with the creation and distribution of the 2018 Clean Water
CCR.
RECOMMENDATION:
Staff recommends the Utility Board take the following action:
1)Receive and file this information report.
ANALYSIS:
In 1996, Congress amended the Safe Drinking Water Act (SDW A), adding a requirement that
water systems deliver to their customers a brief annual water quality report, similar to the Annual
Water Quality Report (AWQR) that California water systems began distributing in 1990.
However, the CCR regulatory requirements are more specific and detailed in terms of content
and format than those for the A WQR.

Regulatory requirements pertaining to the creation and distribution of the CCR fall under the
California Code of Regulations (Title 22, Chapter 15, Article 20) and California Health and
Safety Code (HSC, section 116470). These regulations stipulate the information that must be
included within the report, including information on source water, levels of any detected
contaminants, compliance with drinking water regulations, monitoring requirements, and
educational information. Data for the water quality table is gathered throughout the year by
ALW’s state certified operators. Over 2,400 samples are sent to a third party accredited
laboratory for analysis with the results sent to ALW and the State Water Resources Control
Board, Division of Drinking Water (SWRCB – DDW).
At the beginning of each year, water quality information is collected from the previous calendar
year and populated in the current CCR format. In addition to including mandated language,
ALW uses the CCR to communicate the value of water, promote wise use, build community trust
and customer satisfaction, and encourage investment in resource protection and infrastructure.
The 2018 CCR includes water quality information from January 1, 2018 through December 31,
2018. ALW has distributed the CCR via the SWRCB – DDW Electronic Delivery method,
mailing bill inserts with the Uniform Resource Locator (URL) and a notice explaining the nature
of the link. The URL takes the consumer directly to where the CCR is posted on ALW’s website,
and is available in English and Spanish. Printed copies of both languages are available at several
public facilities, including the Azusa City Library and ALW Administration Building, and may
be mailed directly to the consumer, if requested.
FISCAL IMPACT:
The cost associated with printing and translating the bill inserts and Consumer Confidence
Report is approximately $2,000 and is budgeted in Acct. No. 32-40-722-701-6539.

The Azusa Water System
The City of Azusa, a municipality incorporated December 29, 1898,
maintains ownership and operation of the municipal utility referred to
as Azusa Light & Water (ALW). ALW is entrusted with the responsibility
for providing water utility service within its municipal boundaries,
and, since acquiring the Azusa Valley Water Company in 1993,
providing water utility service to portions of the communities
surrounding the City of Azusa. Serving approximately 23,062 active
service connections with an estimated customer population of
106,400, the combined and integrated water systems of the City of
Azusa and the Azusa Valley Water Company comprise Azusa Light &
Water, the largest municipal water utility in the San Gabriel Valley.
Azusa Water Supply
San Gabriel River Watershed 11 Groundwater Wells SGVMWD
• Surface Water from the San Gabriel Canyon watershed treated
at Joseph F. Hsu Water Filtration Plant
• Groundwater pumped from 8 wells in the Canyon Basin
• Groundwater pumped from 2 wells in the Intermediate Basin
• Groundwater pumped from 1 well in the Main San Gabriel Basin
• San Gabriel Valley Municipal Water District Raw Water
Connection
In general, typical sources of drinking water (both tap water and
bottled water) include rivers, lakes, streams, ponds, reservoirs, springs
and wells.
All water provided to ALW customers continues to be
much cleaner than that required by State and Federal
regulations and of superior quality. Through proper
planning and reliable operations and maintenance,
ALW expects our precious water resources to be
clean, safe, and sustainable well into the future.

Immuno-
Compromised
People
Some people may be more vulnerable
to constituents in the water than the
general population.
Immuno-compromised people, such
as those with cancer undergoing
chemotherapy, persons with
HIV/AIDS or other immune system
disorders, some elderly persons, and
infants, can be particularly at risk from
infections.
These people should seek advice about
drinking water from their healthcare
providers. USEPA/Centers for Disease
Control (CDC) guidelines on appro pri -
ate means to lessen the risk of
infection from microbial contaminants
are available from the Safe Drinking
Water Hotline (1-800-426-4791).
Definitions
Notification Level & Action Level —
The concentration of a contaminant
which, if exceeded, triggers treatment
or other requirements which a water
system must follow.
Cryptosporidium — A microscopic
organism which, when ingested, can
cause diarrhea, fever and other
gastrointestinal symptoms. The
organism comes from animal waste
and may occur in surface watersheds.
If detected, cryptosporidium is
eliminated by an effective treatment
combination including sedimentation,
filtration and disinfection.
Contamination Limits
Drinking water may reasonably be expected to contain at least small
amounts of contaminants. 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 activities. The
presence of contaminants does not necessarily indicate that drinking
water poses a health risk.
More information about contaminants and potential health effects can
be obtained by calling the USEPA’s Safe Drinking Water Hotline (1-
800-426-4791).
Nitrates
Nitrate in drinking water at levels above 10 mg/L, measured in Nitrate
as Nitrogen, is considered a health risk for infants of less than six
months of age. High Nitrate levels in drinking water can interfere with
the capacity of the infant’s blood to carry oxygen, resulting in serious
illness; symptoms include shortness of breath and blueness of the skin.
High Nitrate levels may also affect the ability of the blood to carry
oxygen in other individuals, such as pregnant women and those with
specific enzyme deficiencies.
Well Nitrate levels may rise for short periods of time due to rainfall or
agricultural activity. Where higher Nitrate levels are present, you
should seek advice from your healthcare provider or choose to use
bottled water for mixing formula and juice for your baby; if you are
pregnant, you should drink bottled water. Water purveyors are
required by State Health regulations to issue warnings to customers
when drinking water nitrate levels exceed 10 mg/L. Average Nitrate
Azusa produces its water from the upper reaches of the San
Gabriel River, near the mouth of San Gabriel Canyon, far upstream
of the contaminated groundwater zones found elsewhere in the
San Gabriel Valley.
UB-36
Maximum Contaminant Level Goal
(MCLG)— The level of contaminant in
drinking water below which there is no
known or expected risk to health.
Maximum contaminant level goals are
set by the EPA.
Maximum Residual Disinfectant
Level (MRDL)— The level of a
disinfectant added for water
treatment that may not be exceeded at
the consumer’s tap.
Maximum Residual Disinfectant
Level Goal (MRDLG)— The level of a
disinfectant added for water
treatment below which there is no
known or expected risk to health.
MRDLGs are set by the U.S. EPA.
Maximum Contaminant Level (MCL)
— The highest level of a contaminant
that is allowed in drinking water. MCLs
are set as close to the public health
goals and maximum contaminant level
goals as is economically and
technologically practicable.
Primary Drinking Water Standard —
Primary maximum contaminant levels,
specific treatment techniques adopted
in lieu of primary MCLs, and
monitoring and reporting
requirements for MCLs that are
specified in regulation.
Public Health Goals (PHG)— The
level of a contaminant in drinking
water below which there is no known
or expected risk to health. Public
health goals are set by the California
Environmental Protection Agency.
Radon — A radioactive gas found
throughout the United States that
can’t be seen, tasted or smelled. It can
move up into a building through the
ground through cracks and holes in
the foundation and can build up to
high levels. Radon can get into indoor
air when released from tap water from
4
levels sampled in the Azusa distribution system range from, .40 to
1.22 mg/L Nitrate as Nitrogen for groundwater and ND (nondetectable)
for surface water.
Trihalomethanes
Trihalomethanes (THM’s) are a family of disinfection byproduct
chemicals formed when a disinfectant such as chlorine is added to the
water supply and mixes with naturally occurring organic material found
primarily in Surface Water. Disinfection is an important and necessary
step in the water treatment process that protects against harmful
bacteria and other potential contamination. Chlorine is the most widely
used and approved water system disinfectant in the United States.
The amount of Total THM’s allowed in drinking water is regulated by
the EPA, which has set a Total THM (TTHM) annual average safe limit
of 80 μg/L in drinking water. Results of a health study released in early
1998 suggest that women who drink five glasses of water daily and are
in the first three months of pregnancy may have an increased risk of
miscarriage from TTHM levels in drinking water above 80 μg/L. State
officials have cautioned that the study is not definitive and have stated
that more study on the issue is needed. Average TTHM levels sampled
in the Azusa distribution system for all four quarters in 2016 are 48
μg/L for groundwater and 43 μg/L for surface water.
The Joseph F. Hsu Filtration Plant uses latest filtration
technology to filter up to 12 million gallons per day.
Definitions (cont.)
This Consumer Confidence Report reflects changes in drinking water regulatory
requirements during 2016. All water systems are required to comply with the state Total
Coliform Rule. Beginning April 1, 2016, all water systems are also required to comply with
the federal Revised Total Coliform Rule. The new federal rule maintains the purpose to
protect public health by ensuring the integrity of the drinking water distribution system
and monitoring for the presence of microbials (i.e. total coliform and E. coli bacteria). The
USEPA anticipates greater public health protection as the new rule requires water systems
that are vulnerable to microbial contamination to identify and fix problems. Water systems
that exceed a specified frequency of total coliform occurrences are required to conduct an
assessment to determine if any sanitary defects exists. If found, these must be corrected by
the water system.UB-37

showering, washing dishes, and other
household activities. Radon entering
the home through tap water will, in
most cases, be a small source in indoor
air as compared to radon entering the
home through soil. Radon is a known
carcinogen and breathing air
containing radon can lead to lung
cancer. Drinking water containing
radon may cause increased risk of
stomach cancer. If you are concerned
about radon, testing the air in your
home is inexpensive and easy. For
information call EPA’s Radon Hotline
(1-800-SOS-RADON).
Treatment Technique — A required
process intended to reduce the level of
a contaminant in drinking water.
Turbidity — A measure of the
cloudiness of the water. Turbidity is
monitored because it is a good
indicator of water quality. High
turbidity can hinder the effectiveness
of disinfection.
Variance — State or EPA may give
permission not to meet an MCL or a
treatment technique under certain
conditions.ADON).
Unregulated
Contaminants
Boron — Some men who drink water
containing boron in excess of the
notification level over many years may
experience reproductive effects, based
on studies in laboratory animals.
Vanadium — The babies of some
pregnant women who drink water
containing vanadium in excess of the
notification level may have an
increased risk of developmental
effects, based on studies in laboratory
animals.
5
Drinking Water Contaminants
Inorganic contaminants — Salts and metals, which can be naturally
occurring or result from urban stormwater runoff, industrial or
domestic wastewater discharges, oil and gas production, mining, or
farming.
Microbial contaminants — Viruses and bacteria which may come
from sewage treatment plants, septic systems, agricultural livestock
operations, and wildlife.
Organic chemical contaminants — Synthetic and volatile organic
chemicals, which are byproducts of industrial processes and
petroleum production, and can also come from gas stations, urban
stormwater runoff, and septic systems.
Pesticides and herbicides — Can come from a variety of sources
such as agriculture, urban or stormwater runoff, and residential uses.
Radon — Can be naturally occurring or the result of oil and gas
production and mining activities.
Perchlorate — Some people who drink water containing perchlorate
in excess of the notification level may experience effects associated
with hypothyroidism. Perchlorate interferes with the production of
thyroid hormones, which are required for normal pre- and postnatal
development in humans, as well as normal body metabolism.
Arsenic — While your drinking water meets the federal and state
standard for arsenic, it does contain low levels of arsenic. The arsenic
standard balances the current understanding of arsenic’s possible
health effects against the costs of removing arsenic from drinking
water. The U.S. Environmental Protection Agency continues to
research the health effects of the 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.
To maintain high quality water, Water Treatment Plant Operators
certified by the State Water Resources Control Board (SWRCB)
Division of Drinking Water are operating Azusa’s Joseph F. Hsu
Water Filtration Plant on a regular basis, treating and monitoring
the quality of the drinking water we serve.

LEAD TESTING IN SCHOOLS
The State Water Resources Control Board, Division of Drinking Water (DDW), in collaboration with the California Department of Education, have taken the initiative to test for Lead in drinking water at all
public schools serving kindergarten or any of grades 1-12, inclusive, and preschools and child day care facilities located on public school property. In early 2017, DDW and Local Primacy Agencies issued
amendments to the domestic water supply permits of approximately 1,200 community water systems, including Azusa Light & Water (ALW), so that applicable facilities served by a community water
system could request water sampling for Lead and receive technical assistance if an elevated Lead sample is found. To further safeguard water quality in California’s K-12 public schools, California
Assembly Bill 746, approved on October 13, 2017, required community water systems to test lead levels by July 1, 2019, in drinking water at all California public, K-12 school sites constructed before
January 1, 2020. ALW has satisfied this requirement by completing Lead testing of drinking water in all 26 schools served by the utility. For more information, go to
https://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/leadsamplinginschools.html.
