Our Drinking Water Meets or Exceeds All
Federal (EPA) Drinking Water Requirements
This report is a summary of the quality of the water we
provide our customers. The analysis was made by using the
data from the most recent U.S. Environmental Protection
Agency (EPA) required tests and is presented in the
following pages. We hope this information helps you
become more knowledgeable about what is in your drinking
water. Should you have questions or need additional copies
of this report, please call the District office at (682) 831-4600.
The report is also available on our website at
www.tcmud.ora.
Special Population Advisory
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; 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 at (800)
426-4791.
Water Sources:
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. Contaminants that may be present in source
water before treatment include:
• Microbial contaminants, such as viruses and
bacteria, which may come from sewage
treatment plants, septic systems, and
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 and
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.

Where Do We Get Our Drinking Water?
Our drinking water is obtained from both surface and
groundwater sources. Surface water is purchased from the
City of Fort Worth and its sources are Lake Worth, Eagle
Mountain Lake, Lake Bridgeport, Richland Chambers
Reservoir, Cedar Creek Reservoir, and the Clear Fork
Trinity River (from Lake Benbrook). Groundwater sources
are from four wells including three from the Paluxy Aquifer
and one from the Trinity Aquifer. The Texas Commission on
Environmental Quality (TCEQ) completed an assessment of
your drinking water sources and results indicate that some
of your sources are susceptible to certain contaminants. The
sampling requirements for your water system are based on
this susceptibility and previous sample data. Any detection
of these contaminants may be found in this report. For more
information about your sources of water please refer to the
Source Water Assessment Viewer available at
http://www.tcea.texas.aov/ais/swaview. Further details
about sources and source -water assessments are available
on Texas Drinking Water Watch at
http://dww2.tcea.texas.aov/DWW/. For more information on
source water assessments and protection efforts in our
system, contact John Carman at (682) 831-4600.
All Drinking Water May Contain Contaminants
When drinking water meets federal standards there may not be any health -based benefits to purchasing bottled water or
point -of -use devices. 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. In order to ensure tap water is safe to drink, the EPA and TCEQ prescribe regulations which limit the amount of
certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in
bottled water, which must provide the same protection for public health. More information about contaminants and
potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline at (800) 426-4791.
Water Quality Data
The table in this report lists all the drinking water contaminants we detected during tests conducted from the previous
calendar year, unless otherwise noted. The state requires us to monitor for certain contaminants less than once per year
because the concentrations of these contaminants are not expected to vary significantly from year to year. Therefore,
some of the data, though representative of the water quality, is more than one year old.
Secondary Constituents
Many constituents (such as calcium, sodium or iron) which are often found in drinking water, can cause taste, color and
odor problems. The taste and odor constituents are called secondary constituents and are regulated by the State of Texas,
not the EPA. These constituents are not causes for health concerns. Therefore, secondary constituents are not required
to be reported in this document, but they may greatly affect the appearance and taste of your water.
About the Following Pages
The pages that follow list all of the federally regulated or monitored contaminants which have been found in your drinking
water. The United States Environmental Protection Agency (EPA) requires water systems to test up to 97 constituents.
Please note that not all constituents are required to be sampled every year. Only the most recent year for sampling of a
constituent is included in the report.
Definitions
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water
system must follow.
Action Level Goal (ALG): The level of a contaminant in drinking water below which there is no known or expected risk to health. ALGs
allow for a margin of safety.
Average (Avg): Regulatory compliance with some MCLs are based on running annual average of monthly samples.
Maximum Contaminant Level (MCL): The highest permissible level of a contaminant in drinking water. MCLs are set as close to the
MCLGs as feasible using the best available treatment technology.
Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected
health risk. MCLGs allow for a margin of safety.
Maximum Residual Disinfectant Level (MRDL): The highest level of 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 (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 contamination.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.

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. Trophy Club Municipal Utility District No. 1 is responsible
for providing high quality drinking water but 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 the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

Total Coliform Bacteria are used as indicators of microbial contamination of drinking water because testing for them is easy. While not disease -causing
organisms themselves, they are often found in association with other microbes that are capable of causing disease. Coliform are more hardy than
many disease -causing organisms; therefore, their absence from water is a good indication that the water is microbiologically safe for human
consumption.
