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.
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.
Overview
YOUR DRINKING WATER IS SAFE
Providing safe and reliable drinking water is the highest priority for the
City of Terrell water department. Our employees take pride in providing and
delivering water to your home or business.
The information in this report is based on test conducted from 1993 through
1998.
It is important to us that you have information about your Drinking Water
so you can have confidence in the product we deliver.
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.

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.
Some people may be more vulnerable to contaminants in drinking water than
is 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. EPA/CDC guidelines on appropriate means to lessen the
risk of infection by Cryptosporidium are available from the Safe Drinking
Water Hotline (800-426-4791).
