Sources of Drinking Water
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, radioactive material, and can
pick up substances resulting from the presence of animals or from human activity.
Drinking water, including bottled water, may reasonably be expected to contain at least small
amounts of some contaminants. The presence of contaminants does not necessarily indicate that water
poses a health risk. More information about contaminants and potential health effects can be
obtained by calling the EPAs Safe Drinking Water Hotline at (800) 426-4791.
Contaminants that may be present in source water include:
• Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment
plants, septic systems, agricultural livestock operations, and wildlife.
• Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result
from urban storm water 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 storm water runoff, and residential uses.
• Organic chemical contaminants, including synthetic and volatile organic chemicals, which are
by-products of industrial processes and petroleum production, and can also come from gas stations,
urban storm water runoff, and septic systems.
• 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 fo contaminants in bottled water which must provide the same protection for public health.
Contaminants may be found in drinking water that may cause taste, color, or odor problems. These
types of problems are not necessarily causes for health concerns. For more information on taste,
odor, or color of drinking water, please contact the system's business office.
You may be more vulnerable than the general population to certain microbial contaminants, such as
Cryptosporidium, in drinking water. Infants, some elderly, or immunocompromised persons such as
those undergoing chemotherapy for cancer; persons who have undergone organ transplants; those who
are undergoing treatment with steroids; and people with HIV/AIDS or other immune system disorders,
can b particularly at risk from infections. You should seek advice about drinking water from your
physician or health care providers Additional guidelines on appropriate means to lessen the risk of
infection by Cryptosporidium are available from the Safe Drinking Water Hotline (800-426-4791).
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. We are responsible for providing high quality
drinking water, but we 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
Information about Source Water Assessments:
TCEQ completed an assessment of your source water, and results indicated that some of our sources
are susceptible to certain contaminants. The sampling requirements for you water system is based
on this susceptibility and previous sample data. Any detections of these contaminants will be
found in this Consumer Confidence Report. For more information on the source water assessments and
protection efforts at our system, please contact Danny Miller, City Secretary at (254) 672-5311.
Water Quality Test Results Explanation of Acronyms Used in this Report: The following tables
contain scientific terms and measures, some of which may require explanation.
Avg: Regulatory compliance with some MCLs are based on running annual average of monthly samples.
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. MCLGs allow for a margin of safety.
Maximum Residual Disinfectant Level or MRDL: The highest level of a disinfectant allowed in
drinking water. There is convincing evidence that addition of a disinfectant is necessary for
control of microbial contaminants.
Maximum Residual Disinfectant Level Goal or MRDLG: The level of a drinking water disinfectant below
which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use
of disinfectants to control microbial contaminants.
Level 1 Assessment: A level 1 assessment is a study of the water system to identify potential
problems and determine (if possible) why total coliform bacteria have been found in our water
system.
Level 2 Assessment: A level 2 assessment is a very detailed study of the water system to identify
potential problems and determine (if possible why an E. coli MCL violation has occurred and/or why
total coliform bacteria have been found in our water system on multiple occasions.
Treatment Technique or TT: A required process intended to reduce the level of a contaminant in
drinking water.
MFL: million fibers per liter (a measure of asbestos)
na: not applicable
mrem: millirems per year (a measure of radiation absorbed by the body)
NTU: nephelometric turbidity units (a measure of turbidity)
pCi/L: picocuries per liter (a measure of radioactivity)
ppb: micrograms per liter or parts per billion-or one ounce in 7,350,000
gallons of water.
ppm: milligrams per liter or parts per million-or one ounce in 7,350 gallons of water. ppt:
parts per trillion, or nanograms per liter (ng/L)
ppq: parts per quadrillion, or picograms per liter (pg/L)

Revised Total Coliform Rule (RTCR)
The Revised Total Coliform Rule (RTCR) seeks to prevent waterborne diseases caused by E. coli. E.
coli are bacteria whose presence indicates that the water may be contaminated with human or animal
wastes. Human pathogens in these wastes can cause short-term effects, such as diarrhea, cramps,
nausea, headaches, or other symptoms. They may pose a greater health risk for infants, young
children,
