The City of Terrell is proud of the fine drinking water it provides. This
annual water quality report shows the source of our water, lists the results
of our tests, and contains much important information about water and health.
City of Terrell will notify you immediately if there is any reason for concern
about our water.
SPECIAL INFORMATION FOR THE WEAKENED IMMUNE SYSTEM
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 physician or 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).
The bottom line: Is the water safe to drink? Absolutely.
Call us for information about the next opportunity for public participation
in decisions about our drinking water.

Water Source
The City of Terrell is supplied by surface water from the New City Lake
at Elmo. During drought conditions water is pumped from Lake Tawakoni into
the New City Lake at Elmo.
What Do The Tables Mean?
The tables show the results of our water-quality analyses. Every regulated
contaminant that we detected in the water, even in the most minute traces,
is listed here. The table contains the name of each substance, the highest
level allowed by regulation (MCL), the ideal goals for public health, the
amount detected, the usual sources of such contamination, footnotes explaining
our findings, and a key to units of measurement. Definitions of MCL and
MCLG are important.
Maximum Contaminant Level or 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.
Maximum Contaminant Level Goal or MCLG: The level of a contaminant in
drinking water below which there is no known or expected risk to Health.

Turbidity has no health effects. However , turbidity can interfere with disinfection
and provide a medium for microbial growth. Turbidity may indicate the presence
of disease – causing organisms. These organisms include bacteria, viruses,
and parasites that can cause symptoms such as nausea, cramps, diarrhea and
associated headaches

Unregulated Contaminants
City of Terrell did not test for Cryptosporidium or for Radon.
Required Additional Health Information
To ensure that tap water is safe to drink, EPA prescribes limits on the
amount of certain contaminants in water provided by public water systems.
FDA regulations establish limits for contaminants in bottled water.
Drinking water, including bottled water, may reasonably be expected to
contain at least small amounts of some contaminants. The presence of Contaminant
does not necessarily indicate that water poses a health risk. More information
about contaminants and potential health effects can be obtained by calling
the Environmental Protection Agency's 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 radioactive material, and can pick up
substances resulting from the presence of animals or from human activity.
Contaminants that may be present in source water include:
(A) Microbial contaminants, such as viruses and bacteria, which
may come from sewage treatment plants, septic systems, agricultural
livestock operations, and wildlife.
(B) Inorganic contaminants, such as salts and metals, which can
be naturally-occurring or result from urban storm runoff, industrial
or domestic wastewater discharges, oil and gas production, mining,
or farming.
(C) Pesticides and herbicides, which may come from a variety
of sources such as agriculture, storm water runoff, and residential
uses.
(D) Organic chemical contaminants, including synthetic and volatile
organics, which are by-products of industrial processes and petroleum
production, and can also come from gas stations, urban storm water
runoff and septic systems.
(E) Radioactive contaminants, which can be naturally occurring
or be the result of oil and gas production and mining activities.
In order to ensure that tap water is safe to drink, EPA prescribes
regulations which limit the amount of certain contaminants in water
provided by public water systems. FDA regulations establish limits
for contaminants in bottled water that must provide the same protection
for public health.
