Accept the report on Water Quality Relative to Public Health Goals.
DISCUSSION
The United States Environmental Protection Agency (USEPA) sets national regulatory standards,
known as Primary Maximum Contaminant Levels (MCLs). The California Department of Public
Health (CDPH) is then responsible for enforcing compliance with these MCLs, and sometimes
makes them more stringent.
In addition, the California Environmental Protection Agency Office of Environmental Health
Hazard Assessment establishes Public Health Goals (PHGs) for drinking water contaminants to
serve as guidance for regulatory agencies and the public. A PHG represents a health-protective
level for a contaminant that public water systems should strive to achieve, if it is feasible to do so.
A PHG does not establish a "safe" level of a contaminant; it is merely a goal. As long as drinking
water complies with all MCLs enforced by CDPH, it is considered safe for public consumption,
even if it contains contaminants at levels exceeding the PHG.
Under the provisions of the California Health and Safety Code, the City is required to prepare a
special report identifying water quality measurements that have exceeded PHGs. The City
prepared this special report in accordance with the Association of California Water Agencies
(ACWA) guidelines. (See Exhibit 1.) For 2010, 2011, and 2012, the report shows that Santa
Ana's drinking water continues to meet all State of California, Department of Public Health, and
USEPA drinking water standards set to protect public health. However, the City's drinking water
content of naturally occurring uranium, arsenic, and copper exceeded the recommended PHG
levels. Based on the USEPA studies for naturally occurring uranium and arsenic, additional
treatment would be very expensive, marginally effective, and will not result in significant reduction
of the contaminants. Therefore, no action is proposed. The best available technology to reduce
copper levels is optimized corrosion control. The California Department of Public Health has
determined that the City has optimized corrosion control with our treatment and monitoring
procedures. Therefore, implementation of new treatment technologies is also not recommended.

EXHIBIT 1
CITY OF SANTA ANA
REPORT ON WATER QUALITY RELATIVE TO PUBLIC HEALTH GOALS
Background:
Provisions of the California Health and Safety Code (Reference No. 1) specify that larger
(>10,000 service connections) water utilities prepare a special report by July 1, 2013, if their
water quality measurements have exceeded any Public Health Goals (PHGs). PHGs are non-
enforceable goals established by the Cal-EPA's Office of Environmental Health Hazard
Assessment (OEHHA). The law also requires that where OEHHA has not adopted a PHG for a
constituent, the water supplier is to use Maximum Contaminant Level Goals (MCLGs) adopted
by the United States Environmental Protection Agency (USEPA). Only constituents which have
a California primary drinking water standard and for which either a PHG or MCLG has been set
are to be addressed. (Reference No. 2 is a list of all regulated constituents with the MCLs and
PHGs or MCLGs).
There are a few constituents that are routinely detected in water systems at levels usually
well below the drinking water standards for which no PHG nor has MCLG yet been adopted by
OEHHA of USEPA including Total Trihalomethanes. These will be addressed in a future
required report after a PHG has been adopted.
The law specifies what information is to be provided in the report. (See Reference No. 1)
If a constituent was detected in the City's water supply between 2010 and 2012 at a level
exceeding an applicable PHG or MCLG, this report provides the information required by law.
Included is the numerical public health risk associated with the MCL and the PHG or MCLG, the
category or type of risk to health that could be associated with each constituent, the best
treatment technology available that could be used to reduce the constituent level, and an estimate
of the cost to install treatment if appropriate and feasible.
What Are PHGs?
PHGs are set by the California Office of Environmental Hazard Assessment (OEHHA),
which is part of Cal-EPA and are based solely on public health risk considerations. None of the
practical risk-management factors that are considered by the USEPA or the California
Department of Public Health (CDPH) in setting drinking water standards (MCLs) are considered
in setting the PHGs. These factors include analytical detection capability, treatment technology
available, benefits and costs. The PHGs are not enforceable and are not required to be met by
any public water system. MCLGs are the federal equivalent to PHGs.
Water Quality Data Considered:
All of the water quality data collected by our water system between 2010 and 2012 for
the purpose of determining compliance with drinking water standards was considered. This data
1
75A-3
was all summarized in our 2010, 2011, and 2012 Annual Water Quality Reports, which were
mailed to all of our customers. (Reference No. 3)
Guidelines Followed:
The Association of California Water Agencies (ACWA) formed a work group, which
prepared guidelines for water utilities to use in preparing these required reports. The ACWA
guidelines were used in the preparation of this report.
Best Available Technology and Cost Estimates:
Both the USEPA and CDPH adopt what are known as BATs or Best Available
Technology, which are the best known methods of reducing contaminant levels to the MCL.
Costs can be estimated for such technologies. However, since many PHGs and all MCLGs are
set lower than the MCL, it is not always possible nor feasible to determine what treatment is
needed to further reduce a constituent downward to or near the PHG or MCLG, many of which
are set at zero. Estimating the costs to reduce a constituent to zero is difficult, if not impossible
because it is not possible to verify by analytical means that the level has been lowered to zero. In
some cases, installing treatment to try and further reduce very low levels of one constituent may
have adverse effects on other aspects of water quality.
Constituents Detected That Exceed a PHG or a MCLG:
The following is a discussion of constituents that were detected in one or more of our
drinking water sources at levels above PHG.
Naturally Occurring Uranium
The PHG for Natural Uranium is 0.43 pCi/L. The MCL or drinking water standard for
Natural Uranium is 20 pCi/L. We have detected Natural Uranium in 3 of our 20 wells at levels
1.39 to 10.20 pCi/L. The levels detected were below the MCL. The category of health risk
associated with Natural Uranium, and the reason that a drinking water standard was adopted for
it, is that people who drink water containing Natural Uranium above the MCL throughout their
lifetime could experience an increased risk of cancer. The 20 pCi/L MCL established by the
CDPH if complied with should have no adverse health effect. The numerical risk for cancer for
water containing Uranium at the PHG level of 0.43 pCi/L is one case in 1,000,000. The large
water system BAT for Natural Uranium to lower the levels below the PHG is Ion Exchange.
Total water production for all affected wells is 6,060 gallons per minute. Based on the USEPA
studies, the initial cost to treat one thousand gallons of water at 80 percent removal efficiency for
large water systems ranges from $0.67 to $1.84. The on going cost for the treatment ranges from
$0.57 to $0.74 per thousand gallons of water treated. For the City of Santa Ana, the estimated
cost to install such treatment systems (Ion Exchange) ranges between $5.56 and $15.28 Million.
The cost to operate the treatment facilities will range from $4.73 to $6.14 million per year. The
cost to build the treatment facilities would result in an assumed increased cost for each customer
of $16.46 to $45.21 in the first year and from $14.01 to $18.18 per customer annually.
75A2 4
Copper
The PHG for copper is 0.3 mg/L. There is no MCL for Copper. Instead the 90th
percentile value of all samples from household taps in the distribution system cannot exceed an
Action Level of 1.3 mg/L for copper.
The category of health risk for copper is gastrointestinal irritation. Numerical health risk
data on copper have not yet been provided by OEHHA, the State agency responsible for
providing that information.
All of our source water samples for copper in 2012 were less than the PHG. Based on
extensive sampling of our distribution system in 2012, our 90th percentile value for copper was
0.14 mg/L.
Our water system is in full compliance with the Federal and State Lead and Copper Rule.
Based on our extensive sampling, it was determined according to State Regulatory requirements
that we meet the Action Levels for copper. Therefore, we are deemed by CDPH to have
"Optimized Corrosion Control" for our system.
In general, optimizating corrosion control is considered to be the best available
technology to deal with corrosion issues and with any lead or copper findings. We continue to
monitor our water quality parameters that relate to corrosively, such as pH, hardness, alkalinity,
and total dissolved solids. Action will be taken if necessary to maintain our system in an
"Optimized Corrosion Control" condition.
Since we are meeting the "Optimized Corrosion Control" requirements, it is not prudent
to initiate additional corrosion control treatment as it involves the addition of other chemicals,
and there could be additional water quality issues raised. Therefore, no estimate of cost has been
included.
Arsenic
The PHG for arsenic is 0.000004 mg/L. The MCL for arsenic is 0.10 mg/L. We have
detected Arsenic in 6 of our 20 wells at levels 0.002 mg/L - 0.0032 mg/L. The levels detected
were below the MCL. The category of health risk associated with Arsenic, and the reason that a
drinking water standard was adopted for it, is that people who drink water containing Arsenic
above the MCL throughout their lifetime could experience an increased risk of cancer. The 0.10
mg/L MCL established by the USEPA if complied with should have no health effect. The
numerical risk for cancer for water containing Arsenic at the PHG level of 0.000004 mg/L is one
case in 1,000,000. The large system BAT for Arsenic to lower the levels below the PHG is Ion
Exchange. Total water production for all affected wells is 7,980 gallons per minute. Based on
the USEPA studies, the initial cost to treat one thousand gallons of water at 80 percent removal
efficiency for large water systems ranges from $0.67 to $1.84. The on going cost for the
treatment ranges from $0.57 to $0.74 per thousand gallons of water treated. For the City of
Santa Ana, the estimated cost to install such treatment systems (Ion Exchange) ranges between
$5.56 and $15.28 Million. The cost to operate the treatment facilities will range from $4.73 to
$6.14 million per year. The cost to build the treatment facilities would result in an assumed
increased to each customer or $16.46 to $45.21 in the first year and from $14.01 to $18.18 per
customer annually.
75A-5
Recommendations for Further Action:
The drinking water quality of the City of Santa Ana meets all State of California,
Department of Health Services and USEPA drinking water standards set to protect the public
health. To further reduce the levels of the constituents identified in this report that are already
significantly below the health-based Maximum Contaminant Levels established to provide "safe
drinking water", an additional costly treatment process would be required. The effectiveness of
the treatment process to provide any significant reductions in the constituents' levels at these
already low values is uncertain. The health protection benefits of these further hypothetical
reductions are not at all clear and may not be quantifiable. Therefore, no action is proposed.

(2) A brief and plainly worded definition of the terms "maximum
contaminant level," "primary drinking water standard," and "public
health goal."
(3) If any regulated contaminant is detected in public drinking
water supplied by the system during the past year, the report shall
include all of the following information:
(A) The level of the contaminant found in the drinking water, and
the corresponding public health goal and primary drinking water
standard for that contaminant.
(B) Any violations of the primary drinking water standard that
have occurred as a result of the presence of the contaminant in the
drinking water and a brief and plainly worded statement of health
concerns that resulted in the regulation of that contaminant.
(C) The public water system's address and phone number to enable

public water systems serving more than 10,000 service connections
that detect one or more contaminants in drinking water that exceed
the applicable public health goal, shall prepare a brief written
report in plain language that does all of the following:
(1) Identifies each contaminant detected in drinking water that
exceeds the applicable public health goal.
(2) Discloses the numerical public health risk, determined by the
office, associated with the maximum contaminant level for each
contaminant identified in paragraph (1) and the numerical public
health risk determined by the office associated with the public
health goal for that contaminant.
(3) Identifies the category of risk to public health, including,
but not limited to, carcinogenic, mutagenic, teratogenic, and acute
toxicity, associated with exposure to the contaminant in drinking
water, and includes a brief plainly worded description of these
terms.
(4) Describes the best available technology, if any is then
available on a commercial basis, to remove the contaminant or reduce

About Your Drinking Water
1. What are the sources of the water
Santa Ana delivers?
The City of Santa Ana depends on two
sources for the 16.3 billion gallons of
water we supply each year-62% is
groundwater and 38% is imported water,
purchased from the Metropolitan Water
District of Southern California (MWD).
The groundwater accumulates and is
stored beneath the surface of the earth
and then pumped to the surface by 20
city-owned wells. MWD brings Colorado
River water from Lake Havasu and runoff
from the snow pack in the Sierra Nevada
Range in Northern California. The water
is then treated at either the Diemer Fil-
tration Plant in Yorba Linda or the Wey-
mouth Filtration Plant in Laverne before
it is delivered to Santa Ana.
There are seven MWD connections lo-
cated in the City Most of our customers
receive a blending of the two sources,
groundwater and imported water. For
more details, seethe Water Quality Stan-
dards for each of these sources in the
data that follows. Groundwater and im-
ported waterare listed in separate columns.
s. What's in my drinking water?
Your tap water may contain different
types of chemicals (organic and inor-
ganic), microscopic organisms (e.g., bac-
teria, algae, viruses) and radioactive ma-
terials (radionuclides), many of which are
naturally occurring. Health agencies re-
quire monitoring for these constituents,
because at certain levels they could make
a person sick. The column marked
"Parameter" lists the constituents found
in the water used by Santa Ana.
3. What are the maximum allowed lev-
els for constituents in drinking water?
Health agencies have maximum contami-
nant levels for constituents so that drinking
water is safe and looks, tastes and smells
good. A few constituents have the letters
'TT" in the MCL column because they do
not have numeri-
cal MCL. Instead,
they have certain

chemotherapy,
persons who
have undergone organ transplants, people
with HIViAIDS or other immune system
disorders, some elderly, and infants can
be particularly at risk from infections. These
people should seek advice about drinking
water from their health care providers.
USEPAiCDC (U.S. Centers for Disease
Control and Prevention) guidelines on
appropriate means to lessen the risk of
infection by Cryptosporidium and other
microbial contaminants are available
from the Safe Drinking Water Hotline
800-426-4791. Cryptosporidium is a mi-
crobial pathogen found in surface water
throughout the U.S. To date, Crypto-
sporidium has not been detected in our
water supply.
Beginning in October 1oo7, water that is
received by the City of Santa Ana from
MWD will have fluoride added to it. Our
well water currently has a naturally occur-
ring fluoride range level of o.18 to 0.56
ppm. Water provided by MWD will have
a fluoride level of o.7 to o.8 ppm. This
plan was approved by the CDC and the
California Department of Public Health.
Additional information may be found by
calling MWD's Water Quality Information
Hotline at 800-354-4420, or by visiting
the following websites: mwdh20.COM/

constituents, total chlorine residual, has an affect the appearance, taste and smell of wa-
MRDL (maximum residual disinfection level) ter, but do not affect the safety of the water
instead of an MCL. unless they also have a primary standard.
The MRDL is the maximum level of a disin-
fectant added for water treatment that is
allowed in water. While disinfectants are
necessary to kill harmful microbes, drinking
water regulations protect against too much
disinfectant being added. Another constitu-
ent, turbidity, has a requirement that 95
percent of the measurements taken must
be below a certain number. Turbidity is a
measure of the cloudiness of the water. We
monitor it because it is a good indicator of
the efficiency of the filtration system.
4. Why are some of the constituents listed
in the section labeled "Primary Stan-
dards" and others in the "Secondary
Standards"?
Constituents that are grouped in the primary
standards section may be unhealthy at cer-
tain levels. Constituents that are grouped
5. How do I know how much of a constituent is
in my water and if it is at a safe level?
With a few exceptions, if the AVERAGE
amount of a constituent found in tap water
over the course of a year is no greater than
the MCL, then the regulatory requirements
are considered to be satisfied. The highest
and lowest levels measured over a year are
shown in the RANGE. Requirements for
safety, appearance, taste and smell are
based on the AVERAGE levels recorded
and not the RANGE.
6. How do constituents get into our water?
Drinking water (both tap water and bottled
water) comes from rivers, lakes, streams,
ponds, 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 ma-
terial, and can pick up substances resulting
from the presence of animals or from human
activity. The most likely source for each con-
stituent is listed in the last column of the table.
7. Are there any potential sources of
contamination in our system?
An assessment of the drinking water wells
for the City of Santa Ana was completed in
December 2oo6. The City wells are consid-
ered most vulnerable to the following activi-
ties associated with contaminants detected
in the water supply: historic agricultural ac-
tivities, golf courses, and application of fertil-
izers. The Citys wells are considered most
vulnerable to the following activities not asso-
ciated with detected contaminates: chemical/
petroleum pipelines, chemical/petroleum
processing/stores, dry cleaners, gas stations,
junk/scrap/salvage yards, metal plating/
finishing/fabrication, plastics/synthetics pro-
ducers, and sewer collection systems.

IMPORTANT INFORMATION ABOUT DRINKING WATER
Monitoring Requirements Not Met For The City of Santa Ana
There are many monitoring requirements
imposed on every pub] is water system. Our
water system staff failed to adequately meet
these requirements on one occasion this past
year, and therefore the City's water system
was in violation of these regulations. It is im-
portant to note that this was not a violation
caused by having contaminants exceed allow-
able levels, rather it was a violation caused
by failing to take the required number of
samples within a specific time frame. Even
though this failure was not an emergency, as
our customers, you have the right to know
what you should do, what happened, and
what we did to correct this situation. This
notice is intended to provide you with this
information.
We are required to monitor your drinking
water for specific contaminants on a regular
basis. Results of regular monitoring are an
indicator of whether or not our drinking water
meets health standards. During a period of
April 22 to 26, 2o2o, we did not take the re-
quired number of repeat bacteriological sam-
ples required under Title 22 California Code of
Regulations, Section 64424 (c), and therefore
cannot be sure of the quality of our drinking
water during that time.
What should I do?
i. There is nothing you need to do at this time.
2. The table below lists the contaminant we
did not property test for during the last
year, how many samples we are required to
"Academy Awards of Water," the competition
is the largest and longest running water tast-
ing in the world dedicated to preserving and
protecting drinking water.
Similar to a wine tasting, a dozen judges were
asked to taste water from nearly ioo different
sources, rating the water for
each attribute including ap-
pearance (should be clear),
aroma (should be none), taste
(should taste clean), mouth
feel (should feel light), and
aftertaste (should leave you
take and how often, how many samples we
took, when samples should have been
taken, and the date on which follow-up
samples were taken.
What happened? What is being done?
We have provided additional training to our
staff so that there is no misunderstanding in
the proper time frame and amount of repeat
samples required when a positive bacteriologi-
cal sample has been reported by the laboratory.
We have performed and continue to perform
all of the required water system monitoring
required under Title 22 to ensure the water
provided to our customers is in full compliance
with all regulations. For more information,

How To Read Your
Water Meter
Como Leer Su
Contador De Aqua
Your water meter is usually located between the
sidewalk and curb under a cement cover. Remove
the cover by inserting a screwdriver in the hole in the
Ild and then carefully lift the cover. The meter reads
straight across, like the odometer on your car. Read
only the white numbers. If you are trying to deter.
mine if you have a leak. turn off all the water in your
home. both indoor and outdoor faucets, and then
check the dal for any movement of the numbers. If
there is movement, chat indicates a leak between the
niter and your plumbing system.

El aqua potable, incluyendo el aqua embotel-
lada, puede razonablemente contener por to
menos, pequenas cantidades de agunos con-
taminantes. La presencia de contaminantes
no indica necesariamente que el aqua presente
un riesgo para la satud. Puede aprender mss
acerca de los contaminantes y de sus efectos
potenciales sobre la salud, Ilamando a la linea
directa de "Aqua Potable Segura" (Safe Drinking
Water Hotline) de la Agencia de Proteccion
Ambiental de Estados Unidos (U.S. Environ-
mental Protection Agency (USEPA)) al
800.426.4791, o visitando su sitio Web
www.epa.gov/safewater/.
Para asegurar que el aqua de la Ilave sea
segura para beber, la USEPA ordena
regulaciones clue limitan la cantidad
de ciertos contaminantes en el aqua
clue suministran los sistemas publicos.
Las regulaciones de la FDA (Food and
Drug Administration) establecen
Iimites para los contaminantes en
el aqua embotellada. Amboscon-
juntos de requisitos protegen la
saludpublica. Aigunas personas
pueden ser mss vulnerables a
los contaminantes en el agua

Las normas de USEPA/USCDC (Centro Para
el Control y la Prevenc16n de la Enfermedad
de los E.E.U.U.) sobre medics apropiados para
reducir infecci6n a causa de Criptosporidio y
otros contaminantes microbianos estan dis-
ponibles en la Linea Gratis de Agua Potable
Segura al 800-426-4791 o en su sitio en el inter-
net (www.epa.gov/safewa ter). Hasta la fecha,

Comenzando en octubre de 2007, se agregara
fluoruro al aqua que recibe la Ciudad de Santa
Ana a travis del Metropolitan Water District of
Southern California (MWD). El agua de pozo
de la Ciudad contiene un nivel de fluoruro de .28 a
o.S6 ppm en forma natural. EI aqua proporcio-
nada por MWD tendra un nivel de fluoruro de
0.7 a o.8 ppm. Este plan fue aprobado por el
USCDC y el Departamento de la Salud Publica
de California. Para mayor informacicn Ilame

del aqua. Mientras clue los desinfectantes son
necesarios para matar a los microbios daninos,
las regulaciones del aqua potable protegen
contra el use excesivo de desinfectantes.
Otro elemento, la turbidez, tiene el requisito
de clue el 95% de las medidas tomadas deben
estar por debajo de cierta cantidad. La tur-
bidez es una medida de la "nubosidad" del agua.
La controlamos ya clue es un buen indicador de
la eficacia de nuestro sistema de filtrado.
4. iPorqud algunos de los elementos estin
detallados en la secci6n denominada
"Parimetros Primarios" y otros en la
denominada " Parimetros Secundarios"?
Los elementos que estin agrupados en la sec-
cion de parimetros primxios pueden, en ciertos
niveles, resultar insalubres. Los elementos clue
estan agrupados en los parimetros secundarios
pueden afectar el aspecto, gusto y olor del agua,
pero no afectan la seguridad del agua, salvo
clue tambien tengan un parametro primario.
s. i0mo se que cantidad de un elemento se
encuentra en mi agua y si este se presenta
en un nivel considerado seguro?
Con pocas excepciones, si la cantidad PROME-
DIO de un elemento encontrado en el agua de
la Have durante el transcurso de un ano no es
mayor clue el MCL, se considera que el aqua
cumple con los requisitos reguladores. Los
niveles mis altos y mas bajos medidos durance
un aft, se muestran en la columna RANGO.
Los requisitos para la segundad, el aspecto, el
gusto y el olor se basan en los niveles PROME-
DIO y no en los de RANGO.
6. iDe que forma ingresan los elementos a
nuestro suministro de agua?
Agua para beber (tanto de la Have como embo-
tellada) proviene de rios, lagos, arroyos, la-
gunas, presas, manantiales y pozos. Mientras
el aqua corre sobre la superficie de la tierra o
subterraneamente, este disuelve minerales
naturales y en algunos casos, material radioac-
tive, y puede recoger sustancias clue resultan
de la presencia de anlmales o actividad hu-
mana. En la ultima columna de la tabla, se de-
talla el origen mas probable de cada elemento.
7. iHay alguna fuente de contaminacion
potencial en nuestro sistema?
Se hizo una evaluaci6n de los pozos de agua
potable para la Ciudad de Santa Ana en
Diciembre zoo6. Los pozos son considerados
mas vulnerables seg6n las siguientes activi-
dadesasociadascon contaminantesdetecta-
dos en la fuente de aqua: actividades de agri-
cultura historicas, aplicad6n de fertilizantesy
Campos de golf. Se considera que los pozos de
la Ciudad son mas vulnerables a las siguientes
actividades no asociadas con los contami-
nantes detectados: oleoductos o tuberias
quimicas; almacen o procesamiento de quimi-
cas o de petr6leos, tintorerias, gasolineras,
corral de metal chatarra, chapado, tiraderos
de basura, desecho y chatarra, produccion de

INFORMACION IMPORTANTE ACERCA DEL AGLIA POTABLE
Requisitos de Sequimiento No Cumplidos por la Ciudad de Santa Ana
Existen numerosos requisitos de seguimiento
impuestos sobre cada sistema de aqua p6blico.
En una ocasi6n, el ano pasado, nuestro personal
en el sistema de aqua no logro cumplir en forma
apropiada con estos requisitos, por la canto el
sistema de agua de la Ciudad estuvo en incum-
plimiento de estos reglamentos. Es importante
tomar nota clue este incumplimiento no fue
causado por un exceso en los niveles de con-
taminantes permitidos; mas bien el incum-
plimiento fue causado por no haber tornado
el numero de muestras requeridas en un
marco de tiempo determinado. Aunque este
incumplimiento no fue una emergencia, ust-
edes, por ser nuestros consumidores, tienen el
derecho de saber to clue tienen clue hacer, clue
fue to clue paso, y clue hicimos para corregir
esta situaci6n. Este aviso tiene como intencion
proveerles esta information.
Tenemos el requisito de monltorear con regu-
laridad su agua potable para verificar ciertos
contaminantes especificos. Los resultados de
este seguimiento regular son un indicador para
saber si nuestra agua potable cumple o no, con
los estandares de salud. Durance un periodo del
22 and 26 de abril, 2oto, no tomamos el numero
requerido de pruebas repetidas de muestras
bacteriol6gicas bajo el Articulo 22 del C6digo de

no podemos asegurar la calidad del nuestra
agua potable durante eso periodo.

the cover by inserting a screwdriver in the hole in the
lid and then carefully lift the cover. The meter reads
straight across, like the odometer on your car. Read
only the white numbers. If you are trying to deter-
mine if you have a leak. turn off all the water in your
home, both indoor and outdoor faucets, and then
check the dial for any movement of the numbers. If
there is movement, that indicates a leak between the
meter and your plumbing system.

CONSUMER CONFIDENCE REPORT
Santa Ana's Water Makes A Big Splash As
One Of The World's Best Tasting On Tap!
/ anta Ana's Water Resources Division
was recently recognized for produc-
ing one of the best tasting and high-
est quality tap water in the world. The City
received the silver award in the "Best Mu
nicipal Water' category at the Berkeley
Springs International Water Tasting
Festival, a serious and accred-
ited competition that at-
tracts water submissions
from all over the world
each year.
"This is the second
consecutive year our
water has rated
among the top in the
world, an award we
are proud to receive,'
says Ray Burk, former Water Resources
Manager, City of Santa Ana. "It demon-
strates the stringent standards we set for
our tap water, which are above and beyond
the drinking water health standards required
by both state and federal agencies."
These health standards are outlined
in this Water Quality Report,
which demonstrates how
Santa Ana's water is
meeting all of the drink-
ing water health stan-
dards required by both
the State of California
Department of Public
Health and the United
States Environmental
Protection Agency.
(Read this important health information about drinking water contaminants.)
Your Water, Your Health
Drinking water,
including bottled
g water, mayrea-
t1 sonably be
t expected to
5
contain at least
t small amounts
?
of some con-
taminants. The
presence ofcon-
taminants does
not necessarily
indicate that
the water poses
a health risk. You
can learn more about contaminants and
potential health effects by calling the U.S.
Environmental Protection Agency's (USEPA)
Safe Drinking Water Hotline at 8oo-426-4791
or visiting theirwebsite at epa.govfsafewater/.
To ensure that tap water is safe to drink, the
USEPA prescribes regulations, which 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. Both sets of requirements protect
public health. Some people may be more
vulnerable to contaminants in drinking water
than the general population. Immunocom-
promised persons such as persons with can-
cer 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 about drinking
water from their healthcare providers.
USEPA/CDC (U.S. Centers for Disease Con-
trol and Prevention) guidelines on appropri-
ate means to lessen the risk of infection by
Cryptosporidium and other microbial con-
taminants are available from the Safe Drink-
ing Water Hotline 800-426-4791. Crypto-
sporidium is a microbial pathogen found in
surface water throughout the U. S. To date,
Cryptosporidium has not been detected in
our water supply.
Beginning in October 2007, water that is
received by the City of Santa Ana from MWD
will have fluoride added to it. Our well water
currently has a naturally occurring fluoride
range level of o.18 to o.S6 ppm. Water pro-
,nded by MWD will have a fluoride level of
0.7 to 0.8 ppm. This plan was approved by
the CDC and the California Department of
Public Health. Additional information may
be found by calling MWD's Water Quality
Information Hotline at: 800-354-4420.

About This Report
The focal point of the water quality report
is a table that lists the actual results of year-
round monitoring for more than 22o con-
stituents. Only the constituents that are
found are listed in the table. Bottled water
is not covered in this report.
By reading the table from left to right, you
will learn the quantity of a constituent
found in Santa Ana's water supply and
how that compares with the allowable
state and federal limits.
You'll also learn the range and average of
the constituent measured as well as its
origin. The questions and answers on the
back, numbers i through 7, will explain the
important elements of the to ble found on
the charts.
A copy of the complete assessment is
available at the Water Resources Agency
office. You may request a summary of the
assessment be sent to you by contacting
us at 724-647-3320. If you have questions
about your water quality, contact:

Water Sources
& Components
1. What are the sources of the water Santa
Ana delivers?
The City of Santa Ana depends on two
sources for the 16.3 billion gallons of water
we supply each year-6z% is groundwater
and 38% is imported water, purchased from
the Metropolitan Water District of Southern
California (MWD).
The groundwater accumulates and is stored
beneath the surface of the earth and then
pumped to the surface by zo city-owned
wells. MWD brings Colorado River water
from Lake Havasu and runoff from the snow
pack in the Sierra Nevada Range in Northern
California. The water is then treated at either
the Diener Filtration Plant in Yorba Linda or
the Weymouth Filtration Plant in LaVerne
before it is delivered to Santa Ana.
There are seven MWD connections located in
the City. Most of our customers receive a
blending of the two sources, groundwater
and imported water. For more details, see
the Water Quality Standards for each of
these sources in the data that follows.
Groundwater and imported waterare listed in
separate columns.
z. What's in my drinking water?
Your tap water may contain different types
of chemicals (organic and inorganic), micro-
scopic organisms (e.g., bacteria, algae, viruses)
and radioactive materials (radionuclides),
many of which are naturally occurring.
Health agencies require monitoring for these
constituents, because at certain levels they
could make a person sick. The column
marked "Parameter" lists the constituents
found in the water used by Santa Ana.
3. What are the maximum allowed levels for
constituents in drinking water?
Health agencies have maximum contaminant
levels for constituents so that drinking water is
safe and looks, tastes and smells good. A few
constituents have the letters "TT" in the MCL
column because they do not have a numerical
MCL. Instead, they have certain treatment
requirements that have to be met. One of
the constituents, total chlorine residual, has
an MRDL (maximum residual disinfection
level) instead of an MCL
The MRDL is the maximum level of a disco
fectant added for water treatment that is
allowed in water. While disinfectants are
necessary to kill harmful microbes, drinking
water regulations protect against too much
disinfectant being added. Another Constitu-
ent, turbidity, has a requirement that 9S per
cent of the measurements taken must be
below a certain number. Turbidity is a meas-
ure of the cloudiness of the water We moni-
tor it because it is a good indicator of the
efficiency of the filtration system.
y. Why are some of the constituents listed
in the section labeled "Primary Stan-
dards" and others in the "Secondary
Standards"?
Constituents that are grouped in the primary
standards section may be unhealthy at cer-
tain levels. Constituents that are grouped
under the secondary standards section can
affect the appearance, taste and smell of
water, but do not affect the safety of the
water unless they also have a primary standard,
S. How do I know how much of a constituent is
in my water and if it is at a safe level?
With a few exceptions, if the AVERAGE
amount of a constituent found in tap water
over the course of a year is no greater than
the MCL, then the regulatory requirements
are considered to be satisfied. The highest
and lowest levels measured over a year are
shown in the RANGE. Requirements for
safety, appearance, taste and smell are
based on the AVERAGE levels recorded
and not the RANGE.
6. How do constituents get into our water?
Drinking water (both tap water and bottled
water) comes from rivers, lakes, streams,
ponds, 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, radio-
active material, and can pick up substances
resulting from the presence of animals or
from human activity. The most likely source
for each constituent is listed in the last column
of the table.
7. Are there any potential sources ofcon-
tamination in our system?
An assessment ofthe drinking water wells
for the City of Santa Ana was completed in
December 2oo6. The City wells are consid-
ered most vulnerable to the following activi-
ties associated with contaminants detected
in the water supply: historic agricultural ac-
tivities, golf courses, and application of fertil-
izers. The Citys wells are considered most
vulnerable to the following activities not as-
sociated with detected contaminates chemi-
cal/petroleum pipelines, chemical/petroleum
processing/stores, dry cleaners, gas stations,
junktstrap/salvage yards, metal plating/
finishing/fabrication, plasticsisynthetics
producers, and sewer collection systems.
(Convnued; rom page i)
vahon. It is an important role considering how
essential water is to our public health, safety,
and welfare.
'Our city council and staff work diligently to
provide, protect and preserve one of our most
precious resources," adds Claudia Alvarez,
Santa Ana's mayor pro tem, who is also presi-
dent of the Orange County Water District. "As
a community, we can all be good stewards of
our natural resources Rather than buying
bottled water, we can reduce our eco footprint
by simply turning on our faucets and, at the
same time, enjoy the healthiest and best tast-
ng tap water possible."
The Academy Awards of Water
More than iSo people and an array of water
officials from the U.S. and abroad attended the
water tasting festival last month in Berkeley
Springs, West Virginia. Touted as the "Academy
Awards of Water," the competition is the larg-
est and longest running water tasting in the
world dedicated to preserving and protecting
drinking water.
Eleven judges, including representatives from
three major television networks, public radio
and print media outlets, were asked to taste
water from among 77 different sources. These
sources included 32 municipal waters from a
dozen states, Canada and South Korea. Simi-
lar to a wine tasting,judges rated the water for
each attribute including appearance (should be
clear), aroma (should be none), taste (should
taste clean), mouth feel (should feel light), and
aftertaste (should leave people thirsty for more).
Santa Ana looks forward to competing and
making another big splash at the Berkeley
Springs festival next year!

i. ZCuiles son las fuentes del agua clue
entrega la Ciudad de Santa Ana?
La Ciudad de Santa Ana depende de dos Fuen-
tes para los 16.3 billones de galones de aqua
que proveemos anualmente - 69% es aqua
subterranea y 31% se le compra al Distrito
Metropolitano de Agua del Sur de California
(MWD). El agua subterrinea se acumula por
debajo de la superficie y despuis es bombeada
hacia la superficie por 20 pozos que son propie-
dad de la Ciudad. MWD trae agua del Rio Colo-
rado desde Lake Havasu y de la corriente de
aqua de nieve de la Cordillera de la Sierra Neva-
da en el Norte de California. Despuis el agua es
filtrada en la Planta de Filtraci6n Diemer en
Yorba Linda o la Planta de Filtraci6n Weymouth
en La Verne, antes de que nos sea entregada.
Hay siete conexiones de MWD en la Ciudad. La
mayorfa de nuestros clientes pueden esperar
una mezcla de las dos fuentes de agua Sri sub-
terrinea a importada. Para mas detalles, vea el
Estindar de Calidad del Agua (Water Quality
Standard) para cada uno de estos recursos, en
los datos a continuaci6n. Fuentes de agua sub-
terrinea y aqua importada estdn listadas en
columnas separadas.
2. ZQui contiene mi agua potable?
Su agua puede contener diferentes tipos de
sustancias quimicas (orginicas a inorginicas),
organismos microsc6picos (p. ej. bacterias,
algas, virus) y materiales radioactivos (radio-
n6clidos), muchos de los cuales estdn en el
ambiente de modo natural. Lasagenciassan-
tarias requieren la monitorizad6n de estos ele-
mentos ya clue pasando ciertos niveles podrian
causar enfermedades. La columna denominada
"Parametros" detalla los elementos encontra-
dos en el agua de la Ciudad de Santa Ana.
3. ZCuales son los niveles miximos permitkios
de los elementos que se encuentran en el
aqua potable?
Las agencias sanitarian tienen MCLs (niveles
miximos de contaminantes) para los elemen-
tos, para que el agua potable sea segura y luzca,
sepa y huela bien. Algunos elementostienen
las tetras "TT" (Ticnica de Tratamiento) en la
columna MCL, debido a clue no tienen un MCL
numirico. En lugar de elio, tienen ciertos requi-
sitos de tratamiento que deben ser cumplidos.
Uno de los elemento; el total del cloro residual,
tiene un MDRL (nivel miximo de desinfecci6n
residual) en lugar de un MCL EI MDRL es el
nivel miximo permitido para un desinfectante,
que se agrega para el tratamiento del aqua.
Los elementos que estdn agrupados en la
section de parametros primar os pueden, en
ciertos niveles, resultar rnsalubres. Los elemen-
tos que estdn agrupados en los parametros
secundanos pueden afectar el aspecto, gusto y
olor del agua, pero no afectan la seguridad del
aqua, salvo que tambien tengan un parametro
primario. Algunos componentes (por ej., el
aluminio) tiene dos MCL diferentes, uno para
los mpactos relacionados con la salud y otro
para los impactos no relacionados con la salud.
5. ZC6mo se qui cantidad de un elemento se
encuentra en m) aqua y si iste se presenta
en un nivel considerado seguro?
Con pocas exceptions, si la cantidad PROME-
DID de un elemento encontrado en el agua de
la Have durance el transcurso de un aAo no es
mayor clue el MCL, se considera clue el aqua
cumple con los requisitos reguladores. Los
niveles mis altos y mis bajos medidos durance
un aft, se muestran en la columna RANGO.
Los requisitos para la seguridad, el aspecto,
el gusto y el olor se basan en los niveles PRO-
MEDIO y no en los de RANGO,
6.1De qui forma ingresan los elementos a
nuestro suministro do agua?
Agua para beber (tanto de la Have como
embotellada) proviene de rios, lagos, arroyos,
lagunas,presas, manantiales y pozos. Mientras
el agua corre sobre la superficie de la tiers o
subterrineamente, esta disuelve minerales
naturales y en algunos casos, material radioacti-
vo, y puede recoger sustancias que resultan de
la presencia de animales o actividad humana.
En la ultima columna de la tabla, se detalla el
origen mis probable de cada elemento.
7. iHay alguna fuente de contaminaci6n
potential en nuestro sistema?
Se hizo una evaluaci6n de los pozos de agua
potable para la Ciudad de Santa Ana en diciem-
bre zoo6. Los pours son considerados mas
vulnerables seg6n las siguientes actividades
asociadas con contaminantes detectadosen la
fuente de agua: actividades hist6ricas de agn-
cultural, apiicaci6n de fertilizantes y Campos de
golf. Se considera que los pozos de la Ciudad
son mas vulnerables a las siguientes actividades
no asociadas con los contaminantes detecta-
dos: oleoductos o tuberias quimicas; aimacin
o procesamiento de quimicos o de petr6leos,
tintorerfas, gasolineras, corral de metal chata-
rra, chapado, tiraderos de basura, desecho y
chatarra, producci6n de sintiticos y plisticos
y sistemas de recolecci6n de drenaje.

How To Read Your Como Leer Su
Water Meter
Your water meter is usually located between the
sidewalk and curb under a cement cover. Remove
the cover by inserting a screwdriver in the hole in the
rid and then carefully rift the cover. The meter reads
straight across, like the odometer on your car. Read
only the white numbers- If you are crying to deter-
mine I you have a leak turn off all the water in your
home, both indoor and outdoor faucets, and than
check the dial for any movement of the numbers. If
there is movement, that indicates a leak between the
meter and your plumbing system
