WHERE DOES
MY WATER
COME FROM?

Tucson Water serves
about 734,000
people in the
Tucson area. The
water supply comes
from approximately
200 groundwater
wells located in and
around the Tucson
metropolitan area
(see map). In urban
Tucson, most of the
wells (also known
as Entry Points to
the Distribution
System or EPDS)
serve the neighborhood in which they are located, with excess supply routed to
reservoirs for use elsewhere in the system. Wells located outside the urban core
often deliver water to a single “collector” main prior to delivery to customers. In
these cases, the collector main is termed a “Combined Entry Point to the Distribution
System”. The Tucson Water system has four combined EPDS:
• The Clearwater well field (which delivers a blend of recharged Colorado River
water and groundwater)
• The Northern Avra Valley well field
• The Santa Cruz well field
• The South Side well field, which contains treated water from the Tucson Airport
Area Remediation Project (TARP)

WERE THERE ANY CONTAMINANTS DETECTED IN MY DRINKING WATER?

Tucson Water regularly monitors the drinking water that is delivered to you to
comply with drinking water regulations set by the USEPA. In addition to this
required monitoring, Tucson Water performs a great deal of discretionary monitoring
in order to provide both Tucson Water staff and customers with additional water
quality information. We are pleased to report that the results from the monitoring
conducted in 2008 met all standards for safe drinking water.
Three inorganic contaminants of special interest are arsenic, fluoride, and nitrate.
Fluoride and arsenic are naturally occurring and tend to increase as water is drawn
from greater depths in our aquifer. Nitrate, on the other hand, is typically found
in higher concentrations near the surface of the aquifer because it is frequently
associated with fertilizer use, septic tanks and other human activities. For more
information, please see the Detected Contaminants Table on page 4 and the detailed
information, which follows the table.
In most cases, the minimum detection level of a contaminant is well below the USEPA
regulatory limit for that contaminant. The table on page 4 lists the contaminants that
were detected in the required drinking water monitoring. To compare the detected
amount with the maximum amount allowed by the USEPA, refer to the Maximum
Contaminant Level (MCL) column in the table. The vast majority of regulated
contaminants were not detected in the drinking water delivered by Tucson Water
and those non-detected results were not included in the table. For a complete list of
all USEPA regulated contaminants, contact the USEPA at 1-800-426-4791 or visit the
USEPA Webster at www.epa.gov/safewater/mcl.html#mcls

WHY ARE THERE CONTAMINANTS
IN MY DRINKING WATER?

DO I NEED
TO TAKE
SPECIAL
PRECAUTIONS?

All drinking water, including bottled water, may
reasonably be expected to contain at least small
amounts of some contaminants. Tucson’s groundwater
contains dissolved minerals and organic compounds,
which have been leached from the rock, sediments,
and plant materials through which the water travels.
One would expect to find beneficial minerals such as
calcium and magnesium, harmless minerals such as
chloride, bicarbonate, and sulfate, and metals such as
iron, copper, arsenic, and lead, which may be either
beneficial or harmless at low concentrations, but
harmful at high concentrations. In addition to these
naturally occurring contaminants, our groundwater
may contain contaminants resulting from industrial or
domestic activities. For this reason, water utilities must
currently monitor for approximately 90 regulated and
25 unregulated contaminants.

While the Safe
Drinking Water Act
regulations are
intended to protect
consumers throughout their lifetime,
some people may be more vulnerable to
infections from drinking water than the general
population. These “at-risk” populations include:
immuno-compromised persons such as persons
with cancer undergoing chemotherapy, people
who have undergone organ transplants, people
with HIV/AIDS or other immune system
disorders, and in some cases, elderly people and
infants. These people should seek advice about
drinking water from their health care providers.
USEPA/CDC guidelines on appropriate means
to lessen the risk of infection by cryptosporidium
and other microbial contaminants are available
from the USEPA’s Safe Drinking Water hotline.

The following language is required by the USEPA
to appear in this report, some of which may not be
applicable to deep groundwater wells, the primary
source of the Tucson Water supply: Contaminants that
may be present in source water can include:
• Microbial contaminants, such as viruses and
bacteria, which may come from sewage, septic
systems, agricultural livestock, and wildlife.
• Inorganic contaminants, such as 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.
• Pesticides and herbicides, which may come from
a variety of sources such as agriculture, urban
stormwater runoff, and residential uses.
• Organic chemical contaminants, including
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.
• Radioactive contaminants, which can be naturally
occurring or be the result of oil and gas production
and mining activities.

HOW
CAN
I HAVE
BETTER
TASTING
WATER?

It may be stating the obvious, but water drawn
from the tap may have a chlorine odor. It
may have also been in contact with your pipes
for several hours or longer. It may contain
dissolved air, and it may be warmer than you
desire. You can improve the taste of your
drinking water by simply drawing it after
other water uses, which brings fresh water to
the tap, then allowing it to stand several hours
or longer in a clean odor-free pitcher or bottle.
You can store your water either on the kitchen
counter or in the refrigerator, depending on
which temperature you prefer. If you store the
water in the refrigerator, you may want to be
sure it is capped to help prevent picking up
refrigerator odors.

In order to ensure that tap water is safe to drink,
USEPA regulations limit the amount of certain
contaminants in water provided by public water
systems. Food and Drug Administration regulations
establish limits for contaminants in bottled water that
must provide the same protection for public health.
Bottled water may come from either a surface water
source or groundwater source, and may be treated
minimally or extensively. For information on the
quality of your bottled water, contact the water bottling
company.

DRINKING
WATER
TERMS
AND DEFINITIONS:

Action Level. The concentration of a contaminant which, if exceeded, triggers a treatment or other requirement
which a water system must follow.
Entry Point to the Distribution System (EPDS). All water sources are monitored at the entry point to the
distribution system before the first customer but after any required treatment.
Maximum Contaminant Level (MCL). 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. If a contaminant is
believed to cause health concerns in humans, then the MCL is set as close as practical to zero and at an acceptable
level of risk. Generally, the maximum acceptable risk of cancer is 1 in 10,000 with 70 years of exposure.
Maximum Contaminant Level Goal (MCLG). 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 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.
Parts Per Billion (ppb). Some constituents in water are measured in very small units. One ppb equals one
microgram per liter. For example, one part per billion equals: 2 drops of water in a 15,000 gallon backyard
swimming pool, one second of time in 31.7 years, or the first 16 inches of a trip to the moon.
Parts Per Million (ppm). One ppm equals one milligram per liter or 1000 times more than a ppb. One part per
million equals: 1/4 cup of water in a typical 15,000 gallon backyard swimming pool or one second of time
in 11.6 days.
Picocurie Per Liter (pCi/l). The quantity of radioactive material in one liter which produces 2.22 nuclear
disintegrations per minute.

DETAILED INFORMATION ON DETECTED CONTAMINANTS
Haloacetic Acids (HAA5) are a group of chemicals
that are formed along with other disinfection
byproducts when chlorine or other disinfectants used
to control microbial contaminants in drinking water
react with naturally occurring organic and inorganic
matter in water. The regulated haloacetic acid
compounds, known as HAA5, are monochloroacetic
acid, dichloroacetic acid, trichloroacetic acid,
monobromoacetic acid, and dibromoacetic acid.
Under the Stage 2 Disinfectants/Disinfection
Byproducts Rule, USEPA has established an MCL of
60 parts per billion. The annual HAA5 average for
2008, calculated from 19 locations, was not detected
at 2 ppb. The minimum detection limit for the
laboratory method used in the analysis for HAAs
is 2 ppb (the MCL is 60ppb).
Total Trihalomethanes (TTHMs) are formed
when chlorine combines with naturally occurring
organic material in water. Since the level of organic
matter in our groundwater is extremely low, these
compounds are found at very low concentrations.
The compounds which make up the TTHMs
include bromodichloromethane, bromoform,
chlorodibromomethane, and chloroform. The highest
result for TTHM during 2008 was 19.5 ppb and the
highest concentration for any of the four compounds
was 10.1 ppb for bromoform. Compliance with the
TTHM standard is based on the running quarterly
average (or a single annual average if sampling once
a year) concentration from 19 distribution monitoring
points. The running annual average for TTHMs in
2008 was 7.6 ppb (the MCL is 80 ppb).
Arsenic is a naturally occurring substance commonly
found in groundwater in the southwestern United
States. EPA has finalized a reduction in the arsenic
drinking water standard from 50 ppb down to 10
ppb. All water utilities were required to have met
this reduced standard by January 2006. While your
drinking water meets USEPA’s reduced standard for
arsenic, it does contain low levels of arsenic. USEPA’s
new standard balances the current understanding
of arsenic’s possible health effects against the cost
of removing arsenic from drinking water. USEPA
continues to research the health effect 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. The highest arsenic concentration detected
during 2008 was 6.2 ppb (the MCL is 10 ppb).

Fluoride is an important naturally occurring mineral
that helps to form healthy teeth and bones. A
concentration of 1 ppm is considered optimum. At
concentrations above 2 ppm, fluoride can cause mild
discoloration of teeth, and exposure at above the MCL
of 4 ppm can cause both severe discoloration of teeth
and over many years of exposure, bone disease.
The highest level of fluoride detected during 2008 was
1.1 ppm in one well (the MCL is 4 ppm).
Nitrate is a form of nitrogen and an important plant
nutrient. Tucson Water performs more frequent
monitoring of wells high in nitrate for extra assurance
that action can be taken when approaching the MCL.
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 heath care provider.
The highest level for nitrate during 2008 was 7.4 ppm
(the MCL is 10 ppm).
Sodium is the sixth most abundant element on Earth
and is widely distributed in soils, plants, water, and
food. A goal of 2400 mg/day dietary sodium has
been proposed by several government and health
agencies. Drinking water containing between 30
and 60 ppm would contribute only 2.5 % to 5% of
the dietary goal if tap water consumption is 2 L/day.
Currently, there is no MCL for sodium in drinking
water. The recommended EPA guidance level for
individuals on a very low sodium diet (500 mg/day)
is 20 ppm in drinking water. The average sodium
level in Tucson water during 2008 was 52 ppm.
Drinking water does not play a significant role
in sodium exposure for most individuals. Those
who are under treatment for sodium-sensitive
hypertension should consult with their health care
provider regarding sodium levels in their drinking
water supply and the advisability of using an
alternative water source or point-of-use treatment to
reduce the sodium.

Barium occurs naturally at very low concentrations in
our groundwater. The highest barium value in 2008
was 0.09 ppm (the MCL is 2 ppm).

DETAILED INFORMATION ON DETECTED CONTAMINANTS (continued)
Coliform Bacteria are commonly found in the
environment and in the digestive tract of animals.
While rarely harmful, Coliform bacteria in drinking
water are indicators that the water may also contain
harmful microorganisms. In 2008, there was only
one positive total coliform sample for the entire year.
The recollect samples were negative. The highest
monthly percentage positive was 0.4 % which
occurred in April. (The MCL is 5% per month or not
more than 12 positives in the 247 samples collected
each month.)
Chlorine Residual Disinfection is maintained
throughout the distribution system.
Approximately 0.8 ppm of chlorine is added to
the drinking water supply at well sites, reservoirs
and other facilities to provide assurance that
water delivered to customers will remain free of
microbiological contamination. This also ensures
that the water meets microbiological drinking water
standards from the time it is pumped from the
ground until it reaches the customer’s tap. Chlorine
Residual Disinfectant is measured from 247 sample
stations where the bacteriological samples are
collected monthly. The annual chlorine residual
disinfectant is calculated using the monthly chlorine
averages for the past 12 months.
The annual average for twelve months of 2008 was
0.89 ppm. The maximum was 0.97 ppm
(The Maximum Residual Disinfectant Limit or
MRDL is 4 ppm).

Adjusted Gross Alpha is a measure of radioactivity
due to naturally occurring minerals in groundwater.
This excludes the radioactivity contributed by either
radon or uranium. In 2008, a representative
EPDS was sampled for adjusted gross alpha. The
highest level for adjusted gross alpha during 2008
was 1.3 picocuries per liter or pCi/L (the MCL for
gross alpha radioactivity is 15 pCi/L).
Uranium is a metallic element, which is highly toxic
and radioactive. The highest level for uranium
during 2008 was 6.3 ppb (the MCL is 30 ppb).
Lead and Copper are naturally occurring metals,
which are generally found at very low levels in
source waters. 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. Tucson Water is responsible for
providing high quality drinking water, but can not
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 at http://www.epa.gov/safewater/lead.
The required lead and copper monitoring was
performed during 2008. The 90th percentile value
was 2 ppb for lead (Action Level is 15 ppb) and 0.12
ppm for copper (Action Level is
1.3 ppm). One sample was above the action level for
lead. A second confirmation sample was collected
from this residence using the proper procedure. No
lead was detected in the second sample. There were
no samples above the action level for copper.

1,4-Dioxane was first detected in 2002. The
laboratory’s minimum reporting limit for this
chemical is 1 ppb, with the highest concentration in
2008 at 2.1 ppb. 1,4 dioxane is used primarily as a
stabilizer in chlorinated solvents, particularly
1,1,1-trichloroethane (TCA). At this time, USEPA has
not set a drinking water standard for this compound.
Therefore, it is not listed on the Detected Contaminant
Table in page 4. However, the EPA Office of Drinking
Water has a Health Advisory Level of 3 ppb.

UCMR Data Availability Unregulated Contaminant
Monitoring Regulation sampling was conducted
by Tucson Water during the fourth quarter of 2008,
results of which were non-detects. Unregulated
contaminants are those that don’t yet have a
drinking water standard set by USEPA. The
purpose of monitoring for these contaminants is to
help EPA decide whether the contaminants should
have a standard. As a Tucson Water customer, you
have the right to know that this data is available.
If you are interested in examining the results,
please contact the Water Quality Division by
calling 791-2544.

SOURCE WATER ASSESSMENT PROGRAM
(SWAP)

HOW IS OUR DRINKING WATER TREATED?

The groundwater delivered by Tucson Water meets
all drinking water standards without treatment, with
the exception of the water supplied from the Tucson
Airport Area Remediation Project or TARP (See
below). However, approximately 0.8 ppm of chlorine
is added to the drinking water supply at well sites,
reservoirs and other facilities to provide assurance
that water delivered to customers will remain free
of microbiological contamination. This also ensures
that the water meets microbiological drinking water
standards from the time it is pumped from the ground
until it reaches the customer’s tap. Additionally, to
elevate the pH in the Clearwater blend, approximately
1.8 ppm of sodium hydroxide, also known as “caustic
soda”, is added to the blend prior to delivery to
customers to achieve a target pH of 8.1. This ensures
that the delivered water is not corrosive. Corrosive
water can damage metallic plumbing and leach metals
such as copper and lead from certain plumbing fixtures
(see Lead and Copper information).

The Arizona Department of Environmental Quality
(ADEQ) has completed a source water assessment
for Tucson Water drinking water wells. This
assessment reviewed the adjacent land uses that
may pose a potential risk to the water sources.
These risks include, but are not limited to gas
stations, landfills, dry cleaning, agricultural fields,
wastewater treatment plants, and mining activities.
The assessment has classified approximately
1/3 of our wells as high risks.
Tucson Water ensures the safety of our drinking
water by conducting regular monitoring of all
sources. If any contamination approaches the
drinking water MCL, the source is removed
from service.
Residents can help protect our water sources
by practicing good septic system maintenance,
limiting pesticide and fertilizer use, and by taking
hazardous household chemicals to the Household
Hazardous Waste Program (visit http://www.deq.
pima.gov/waste/householdhaz.html
or call 791-4502).

MORE ABOUT TARP

The Tucson Airport Area Remediation Project (TARP)
was developed in order to clean and make beneficial
use of water contaminated with the industrial solvent
trichloroethylene (TCE). Tucson Water operates
TARP under an agreement with the USEPA and other
industrial and governmental agencies. All costs
associated with operating and maintaining the TARP
facility are fully reimbursed to Tucson Water.

The complete SWAP report is available for review
at ADEQ, 1110 W. Washington, Phoenix, Arizona
or by requesting an electronic copy by contacting
ADEQ at 800-234-5677.

WHAT ABOUT CAP WATER?

The City of Tucson has rights to approximately
144,000 acre-feet of Colorado River water per year,
delivered through the Central Arizona Project
(CAP). In 2008, the City of Tucson’s Colorado
River allocation was not used directly, but a
portion of this allocation was recharged into the
aquifer. At the end of 2008, Tucson Water was
using approximately 90% of its available allocation.
At the Clearwater Renewable Resource Facility
located in Avra Valley, Tucson Water is recharging
a portion of the City’s available CAP supply by
delivering the river water to shallow basins and
allowing the water to percolate (or recharge)
naturally through the earth to reach and blend
with the groundwater below. Tucson Water began
delivery of this blend of recharged Colorado River
water and groundwater in 2001. At the end of
2008, the blend was about 50% native groundwater
and 50% recharged Colorado River water. Over
time, it will contain an increasing percentage of
recharged Colorado River water. Information
on the quality of this blend is contained in the
detected contaminant table, and more information
is available on Tucson Water’s web site.

Nine wells extract the contaminated water and deliver
it through a pipeline to a treatment plant that removes
the TCE from the water. The TARP treatment plant
uses an “air stripping” process which forces volatile
contaminants such as TCE to evaporate from the water
into air. The air is then passed through activated
carbon filters, which removes the airborne TCE.
The TARP plant is designed to treat approximately
8.4 million gallons of water per day (or 5,800 gallon per
minute). During 2008, this plant treated a total
of approximately 2.394 billion gallons of water.
The treatment system removed 317 pounds
of combined VOCs from the groundwater.

MONITORING WAIVERS

7

The Arizona Department of Environmental Quality,
the regulatory agency for all public water suppliers
in Arizona, grants waivers for certain monitoring
requirements. Waivers are granted for specific
contaminants if previous monitoring results, and/or
the land uses within a half-mile radius of the well,
allow ADEQ to conclude that the risk of contamination
by a specific substance is very low. No monitoring
waivers were in use for 2008.
