“Arizona Water Company has released its 2018 Water Quality Report (Consumer Confidence Report) for its
White Tank water system, PWSID 07-128. The Company will not be mailing a copy of the report to its customers, because Arizona Administrative Code R18-4-117, granted a mailing waiver to small water systems with a
population less than 10,000 people. Copies are available: at the Casa Grande office located at 318 N. Marshall
Street, Casa Grande; via mail by sending a request to Arizona Water Company, P. O. Box 11030, Casa Grande,
AZ 85230; via our website at; or by calling the Casa Grande office at 520-836-8785. The entire
report is also printed in the newspaper today. Arizona Water Company recommends that customers serving
more than one housing unit post a copy of the 2018 Water Quality Report in a conspicuous place.”

Arizona Water Company provides groundwater to its White Tank customers from wells located
throughout the White Tank area.
All water samples are collected by state-certified employees of Arizona Water Company or by the
Arizona Department of Environmental Quality (“ADEQ”). Samples are analyzed by state-certified independent
laboratories and the results are forwarded to ADEQ. The following report provides detailed information about
the quality of the water delivered to customers. The water supplied by Arizona Water Company complies with all
state and federal safe drinking water standards and regulations.

In 2004, ADEQ completed a Source Water Assessment of the water sources used by Arizona Water
Company’s White Tank water system. ADEQ reviewed the adjacent land uses that may pose a potential risk to
the water sources. The result of the Assessment was a low risk to the water sources.

The USEPA and ADEQ require Arizona Water Company to provide the following information:
Drinking water, including bottled water, may reasonably be expected to contain at least small
amounts of some constituents. The presence of constituents does not necessarily indicate that water poses a
health risk. More information about constituents and potential health effects can be obtained by calling the
USEPA’s Safe Drinking Water Hotline (800-426-4791).
Some people may be more vulnerable to constituents in drinking water than the general population.
Immuno-compromised persons such as persons with cancer 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
health care providers. USEPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial constituents are available from the Safe Drinking Water Hotline (800-426-4791).
The sources of drinking water (both tap water and bottled water) include 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, radiological material, and can pick up substances resulting from
the presence of animals or from human activity.
Constituents that may be present in source water include:
Microbials, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
Inorganics, 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.
Organics, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and
petroleum production. They can also come from gas stations, urban stormwater runoff, and septic systems.
Radiological material, which can be naturally-occurring or be the result of oil and gas production and mining
In order to ensure that tap water is safe to drink, USEPA prescribes regulations which limit the
amount of certain constituents in water provided by public water systems. FDA regulations establish limits for
constituents in bottled water which must provide the same protection for public health.
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. Arizona Water Company 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 USEPA’s Safe Drinking Water Hotline or at

Your drinking water complies with the United States Environmental Protection Agency’s (“USEPA”)
safe drinking water standard for arsenic, though it contains low levels of arsenic. USEPA’s safe drinking water
standard balances the current understanding of arsenic’s possible health effects against the costs of removing
arsenic from drinking water. USEPA continues to research the health effects 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.
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.
Note: In addition to the constituents listed in this report, Arizona Water Company conducted monitoring for
over 90 additional constituents and the results show none of those constituents were detected in the water. Data
presented are from the most recent testing done in accordance with applicable regulations. Some constituents
are monitored less frequently than once a year because either their concentrations do not change frequently or
