Consumer Confidence
Report 2007
Our Drinking Water is Regulated
by the Texas Commission
on Environmental Quality (TCEQ) and
they have determined that certain
water quality issues exsist which
prevent our water from metting all
of the requirements as stated in
the Federal Drinking Water Standards.
Each issue is listed in this report
as a violation and we are working
closely with the TCEQ to achieve
solutions.

Where Do We Get Our Drinking
Water?
Our drinking water is obtained from
Ground water sources. It comes from
the following Lake/River/Reservoir/Aquifer:
TWIN MOUNTAIN - TRAVIS PEAK
and PALUXY. TCEQ completed an assessment
of our source water and results indicate
that some of our sources are susceptible
to certain contaminants. The sampling
requirements for our water system
are based on this susceptibility
and previous sample data. Any detections
of these contaminants will be found in this
report. If we receive or purchase water from
another system, their susceptibility is not included
in this assessment. 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 Environmental Protection
Agency's Safe Drinking Water Hotline
(1-800-426-4791).
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 particulary at risk
from infections. These people should
seek advice about drinking water
from their health care providers.
EPA/Centers for Disease Control
and Prevention (CDC) guidlines on
appropriate means to lessen the
risk of infections by Cryptosporidium
and other microbial contaminants
are available from the Safe Drinking
Water Hotline (800-426-4791).
About The Following Pages
The pages that follow list
all of the federally regulated or
monitored constituents which have
been found in your drinking water.
U.S. EPA requires water systems
to test for up to 97 constituents.
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, secondaries are not requiresd
to be reported in this document
but they may greatly affect the
appearance and taste of your water.
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 safty.
Maximum Residual Disinfectant Level (MRDL) -
The higgest level of disinfectant allowed in drinking
water. There is convincing evidence that addition of
a disinfectant is necessary for control of micfobial
contaminants.
Maximum Residual Disinfectant Leve 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.
Action Level - The
concentration of a contaminant which,
if exceeded, triggers treatment or
other requirements which a water system
must follow.
NTU - Nephelometric
Turbidity Units
MFL - million fibers
per liter (a measure of asbestos)
pCi/l - picocuries
per liter (a measure of radioactivity)
ppm - parts per million,
or milligrams per liter (mg/L)
ppb - parts per billion,
or micrograms per liter (µg/L)
ppt - parts per trillion,
or nanograms per liter
ppq - parts per quadrillion,
or picograms per liter
