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.

Emerging Water Quality Issues

The 1996 amendments to the
federal Safe Drinking Water Act (SDWA)
require that once every five years, the
U.S. Environmental Protection Agency
(EPA) issue a new list of no more than 30
unregulated contaminants to be monitored
by public water systems (PWSs). The
Unregulated Contaminant Monitoring Rule
(UCMR) provides EPA and other interested
parties with scientifically valid data on the
occurrence of contaminants in drinking
water.

To help advance the science of
drinking water, Arlington Water Utilities is
collecting data for the EPA regarding the
occurrence of the compounds from the
latest UCMR list in our water supply, which
is the first step in determining whether they
should be regulated. These compounds
include Anatoxin, Cylindrospermopsin and
Total Microcystins, none of which were
detected in tests of Arlington’s drinking
water during 2018.

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 more about the Unregulated
Contaminant Monitoring Rule, visit www.
epa.gov/dwucmr or www.DrinkTap.org.
Chloramine is a disinfectant that keeps the water
safe on its way to your faucet.

Arlington Water Utilities tests drinking water
at over 120 taps all over the city each month. In
2018, the laboratory collected 6,818 samples and
performed 16,073 tests monitoring 269 different
analytes. This report contains data collected from
Jan. 1, 2018 through Dec. 31, 2018, unless another
time frame is noted.

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 (800-
426-4791).
