Annual Water Quality Report
PWS # 0940015
Special
Notice for the ELDERLY, INFANTS, CANCER PATIENTS, people with
HIV/AIDS or other immunce 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. EPA/Centers for
Disease Control (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
IS REGULATED
by the Texas Commission on Environmental Quality (TCEQ) and they
have determined that certain water quality issues exist which prevent
our water from meeting 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 TCEQ to achieve solutions.

Where
do we get our drinking water?
Our
drinking water is obtained from Ground and Surface water sources.
It comes from the following sources: Carrizo-Wilcox
Aquifer, Edwards Aquifer, Guadelupe River and San Marcos River.A Source Water Susceptibility Assessment for your drinking water source(s) is currently being conducted by TCEQ and will be provided to us this year. This report will describe the susecptibility 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 assess ment will allow us to focus our source water protection strategies.
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 resonably 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 (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 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 or 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 required to be reported in this document but they greatly
affect the appearance and taste of your water.
Definitions:
Maximum
Contaminant Level (MCL): The highest
level of a contaminant that is allowed in drinking water. MCL's
are set as close to the MCLG's 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 risk
to health. MCLG's allow for a margin of safety.
Treatment
Technique or TT: A required process intended to reduce the
level of contaminant in drinking water.
Action
Level or AL: The concentration of a contaminant, which if
exceeded, triggers treatment or other requirements, which a water
system must follow.

TURBIDITY
Turbidity
has no health effects. However, turbidity can interfere with disinfection
and provide a medium for microbial growth. Turbidity may indicate
the presence of disease-causing oprganisms. These iorganisms include
bacteria, viruses, and parasites that can cause symptoms such
as nausea, cramps, diarrhea and associated headaches.
