The
City of Terrell is proud of the fine drinking water it provides. This annual
water quality report shows the source of our water, lists the results of our
tests, and contains much important information about water and health. City
of Terrell will notify you immediately if there is any reason for concern
about our water.
New in 2007
The City of Terrell began purchasing treated water from North Texas Municipal
Water District (NTMWD). NTMWD utilizes three reservoirs; Lavon Lake,
Lake Jim Chapman, and Lake Texoma for their raw water supplies. The City
of Terrell’s Water Treatment Plant was closed on June 19, 2007.
Special Information for People with Weakened Immune Systems
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.
The bottom line: Is the water safe to drink? Absolutely.
Call us for information about the next opportunity for public participation
in decisions about our drinking water.

YOUR DRINKING WATER IS SAFE
Providing safe and reliable drinking water is the highest priority for the City of Terrell water department. Our employees take pride in providing and delivering water to your home or business.
The information in this report is based on tests conducted through 2007.
It is important to us that you have information about your Drinking Water so you can have confidence in the product we deliver.
Cryptosporidium and Giardia
The City of Terrell tested the raw water for the presence of Cryptosporidium
and Giardia and neither were detected. NTMWD also tested their raw water and
treated water for the presence of Cryptosporidium and none were detected.
Cryptosporidium and Giardia are a protozoan that is so small it can be seen only with a microscope and is common in surface water. The source is human and animal fecal waste, which affects the digestive tract of humans and animals which could cause diarrhea, cramps, and fever. At this time, there is no specific drug therapy proven to be effective for cryptosporidium, but people with healthy immune systems will usually recover within two weeks.
Water Source
TCEQ completed an assessment of your source water and results indicate that
some of our sources are susceptible to certain contaminants. The sampling
requirements for your water is based on this susceptibility and previous
sample data. Any detections of these contaminants will be found in this
Consumers Confidence report. For more information on source water assessments
and protection efforts at our system contact the Water Treatment Plant,
(972) 551-6635.
The report showed a HIGH susceptibility for the following contaminants: Inorganics, regulated and unregulated; Volatile Organic Contaminant, regulated and unregulated; Synthetic Organic Contaminant, regulated and unregulated; Disinfection By-Product, regulated; and Microbial Organism, unregulated.
What Do The Tables Mean?
The tables show the results of our water-quality analyses. Every regulated
contaminant that we detected in the water, even in the most minute traces,
is listed here. The table contains the name of each substance, the highest
level allowed by regulation (MCL), the ideal goals for public health, the
amount detected, the usual sources of such contamination, footnotes explaining
our findings, and a key to units of measurement. Definitions of MCL and
MCLG are important.
Maximum Contaminant Level or MCL: The highest level of a
contaminant that is allowed in drinking water. MCLs are set as close to the
MCLGs as feasible, using the best available treatment technology.
Maximum Contaminant Level Goal or MCLG: The level of a contaminant
in drinking water below which there is no known or expected risk to health.
MCLGs allow for a margin of safety.
Maximum Residual Disinfectant Level Goal or 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 contaminants.
Maximum Residual Disinfectant Level or MRDL: The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
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 that a water system must follow.
Key To Table
AL = Action Level
MCL = Maximum Contaminant Level
MCLG = Maximum Contaminant Level Goal
NTU = Nephelometric Turbidity Units
pCi/l = picocuries per liter (a measure of radioactivity)
ppm = parts per million, or milligrams per liter (mg/l)
ppt = parts per trillion, or nanograms per liter
ppb = parts per billion, or micrograms per liter (µg/l)
ppq = parts per quadrillion, or picograms per liter
TT = Treatment Technique
ND = Not Detected at the Reporting Limit
Regulated at the Customer's Tap
Contaminant 90th Percentile Values # of Sites Exceeding Action Level Maximum Contaminant Level Maximum Contaminant Level Goal Major Sources in Drinking Water Lead (ppb) 8.22 0 Action Level=15 0 Corrosion of household plumbing systems; Erosion of natural deposits Copper (ppm) 0..52 0 Action Level =1.3 1.3
Regulated at the Treatment Plant
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 organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea and associated headaches
