Special
Notice for the ELDERLY, INFANTS, CANCER PATIENTS, people
With HIV/AIDS or other immune problems:
Some
people may be more vulnerable to contaminants in drinking
water than 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.
The EPA/Centers for Disease Control and Prevention (CDC) guidelines
on appropriate means to lessen the risk of infection by Cryptosporidium
and other microbial contaminants are available from the Safe
Drinking Water Hotline (1-800-426-4791).

Our
Drinking Water Meet 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 attached pages.
We hope this information helps you become more knowledgeable
about what’s in your drinking water.

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: microbes, inorganic contaminants, pesticides, herbicides,
radioactive contaminants, and organic chemical contaminants.

| Where
do we get our drinking water?
Our drinking water is obtained
from Surface and Ground water sources.
It comes from the following Lake/River/Reservoir/Aquifer:
ALLUVIAL, PRE-CAMBRIAN AGE AQUIFER, LAKE
LYDON B JOHNSON.
A Source Water Susceptibility Assessment for your drinking
water sources(s) is currently being updated by the Texas Commission
on Environmental Quality and will be provided to us this year.
The report will describe the susceptibility and types of constituents
that may come into contact with your drinking water source
based on human activities and natural conditions.
The information contained in the Assessment will allow us
to focus our source water protection strategies. For more
information on source water assessments and protection efforts
at our system, please contact us.
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. More information about contaminants
and potential health effects can be obtained by calling the
EPA’s Safe Drinking Water Hotline
(1-800-426-4791).
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 concern.
Therefore, secondaries 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 U.S. EPA requires
water systems to test for up to 97 contaminants.
DEFINITIONS
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 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.
Action
Level (AL)
The concentration of a contaminant which, if exceeded, triggers
treatment or other requirements which a water system must
follow.
