2008 ANNUAL DRINKING WATER QUALITY REPORT (Consumer Confidence Report)
*****OUR DRINKING WATER IS SAFE*****
Our Drinking Water Meets or Exceeds all Federal (E.P.A.)
Drinking Water Requirements
This report is a summary of the
quality of the water that we provide our customers.
The analysis was made by using 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 your
drinking water.
|
HEREFORD'S WATER SOURCES |
|
Where does the City of Hereford get
our drinking water? Our drinking water is obtained entirely from
groundwater sources. The City of Hereford operates 48 wells in and
around the city. Of these wells, 40 pump from the Ogallala aquifer
and 8 that pump from the Santa Rosa aquifer. These wells have a
maximum pumping capacity of 15 million gallons per day. These 48
wells pump into four pump stations in town that have 7 million
gallons of storage capacity. During 2008 the City supplied 1.296
billion gallons of water to the residents and businesses of
Hereford. This calculates to an average of 3.542 million gallons per
day. A Source Water Susceptibility Assessment for your drinking
water source(s) is currently being updated by the Texas Commission
on Environmental Quality (TCEQ) and will be provided to us later
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 call
us. |
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 includes: microbes,
inorganic contaminants, pesticides, herbicides, radioactive
contaminants, and organic chemical contaminants. |
|
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 required to be reported in this document but
they may greatly affect the taste and appearance of your water. |
|
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 these
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). |
|
SPECIAL NOTICE |
|
For the elderly, infants, cancer
patients and 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. 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). |

Additional Health Information for Nitrate
Because
the highest reported nitrate level on this report is above 5 ppm, but below the
MCL, this information is required by the EPA:
“Nitrate in
drinking water at levels above 10 ppm is a risk for infants of less than six
months of age. High nitrate levels in drinking water can cause blue baby
syndrome. If you are caring for an infant you should ask advice from your health
care provider.”

Contaminant Level Goal (MCLG)
-
The
level of a contaminant in drinking water below which there is not
known or suspected health risk. MCLGs allow for a margin of safety. |

Residual Disinfection Level (MRDL)
–
The
highest level of disinfection allowed in drinking water. There is
convincing evidence that addition of a disinfectant is necessary for
control of microbial contaminants. |

|
|
Maximum
Residual Disinfection Level Goal(MRDLG)
– The
level of a drinking water disinfectant below which there is no known
or expected risk to health. MRDLG’s 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

Action
Level (AL)
– The concentration of a contaminant, which if exceeded, triggers
treatment or other requirements, which a water system must follow |

Tips on Water Conservation:
* Stop all leaks - fix leaky faucets, commode tank valves and seals
* Take shorter showers, not baths and use efficient shower nozzles
* Run full loads in dishwashers & washing machines
* Water lawns in the evening or early morning when the wind is calm to reduce
evaporation
* Don't run water while shaving or brushing teeth
* Don't run water to get a cold drink - keep water in refrigerator
The City of Hereford has 6.150 million gallons of
ground storage and 1.0 million gallons of elevated storage.
The responsibilities of the Water Production Department include:
* Supplying a safe potable water supply to 5,250 metered customers
* Maintaining adequate chlorine residual and constant water pressure
* Checking and maintaining 4 Water Plants, 48 well sites, 3 water tower sites, 13
booster pumps, and flow meters.
* Taking bi-monthly bacteria samples by state certified lab
* Tracking water consumption by monthly reports
* Keeping daily pumping totals
* Well surveys of Ogallala & Santa Rosa static water levels, pumping levels,
drawdowns & G.P.M. and well survey reports
* Maintenance of all equipment
Basically, if you turn on the faucet and
good, cold, water comes out - we're doing our job!!
