Know Your H2O From Source to Tap
More than 350 students entered
Arlington Water Utilities’ Value of Water
coloring contest in 2019. Some of the
winners are featured inside.

Arlington Water Utilities takes pride in meeting or exceeding all federal and state
requirements for water quality. The story of how that water gets to homes, schools and
businesses starts at the source. Arlington purchases its water for treatment from the Tarrant
Regional Water District, or TRWD. The water comes from four reservoirs – Cedar Creek, Richland
Chambers, Lake Arlington and Lake Benbrook.

The “raw water” is treated at Arlington’s state-of-the-art Pierce-Burch and John F. Kubala
Water Treatment Plants. Ozone is used as the primary disinfectant. Aluminum sulfate and a
cationic polymer are added to help dirt and other particles clump together and settle out during
treatment. The water is then filtered through granular activated carbon beds to remove smaller
particles and substances that are dissolved in the water. The water is treated with chloramine
(chlorine and ammonia) as it enters storage. Chloramine is a disinfectant that keeps the water
safe on its way to your faucet.

Health information for
special populations

You may be more vulnerable than the general
population to certain microbial contaminants, such
as Cryptosporidium, in drinking water. Infants, some
elderly or immuno-compromised persons such as
those undergoing chemotherapy for cancer; those
who have undergone organ transplants; those
who are undergoing treatment with steroids and
people with HIV/AIDS or other immune system
disorders can be particularly at risk from infections.
You should seek advice about drinking water from
your health care provider. Additional guidelines on
appropriate means to lessen the risk of infection
by Cryptosporidium are available from the Safe
Drinking Water Hotline [phone]).
Emerging Water Quality Issues

Arlington Water Utilities is committed
to protecting public health and meets
or surpasses all state and federal health
standards for tap water. Under the 1996
amendments to the federal Safe Drinking
Water Act, the Environmental Protection
Agency is required once every five years
to issue a new list of up to 30 unregulated
contaminants for which water systems must
monitor. To help advance the science of
drinking water, we have been collecting data
for the EPA regarding the occurrence of
these compounds in our water supply, which
is the first step in determining whether they
should be regulated.

In 2019, the City of Arlington monitored
for two metals, eight pesticides, one
pesticide manufacturing byproduct, three
brominated haloacetic acid (HAA) groups,
three alcohols and three semi-volatile
chemicals in the drinking water at our two
treatment plants as well as at 12 distribution
sites representing all areas of the city. We
also monitored bromide and total organic
carbon in the source waters. Table B on page
3 lists the compounds that were detected
in the study. All others were not detected.
The presence of a compound does not
necessarily equate to a health risk. The
concentration of a compound is a far more
important factor in determining whether
there are health implications. To learn

Monitoring Rule, visit: www.epa.gov/dwucmr
