A Source Water Assessment for your drinking water source(s) is currently being
conducted by the TCEQ and should 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 condi-
tions. The information in this assessment will allow us to focus our source water
Country Ridge Water – WS 0430070 2 2015 Consumer Confidence Report (CCR)
Source of Drinking Water The source of drinking water used by COUNTRY
RIDGE WATER is Groundwater from the Woodbine
aquifer located in Collin County. 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 natural-
ly-occurring minerals and, in some cases, radioactive
material, and can pickup substances resulting from the
presence of animals or from human activity. Contami-
nants that may be present in source water include:
Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants,
septic systems, agricultural livestock operations, and wildlife.
Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban
storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farm-
ing.
Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm run-
off, and residential use.
Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products
of industrial processes and petroleum production, and can also come from gas stations, urban storm runoff,
and septic systems.
Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and
mining activities.
Information about Secondary Contaminants 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 often called secondary constituents and are reg-
ulated 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.
TASTE AND ODOR ISSUES: Each summer, throughout the months of July and August, lakes and other surface water supplies experience a natural event - “algae
bloom.” Algae blooms are common to surface water supplies in warm climate states like Texas. The algae blooms are responsible for
the grassy, earthy taste and smell that may occur during the hot and dry season. The blue-green algae species Nostoc and Anabaena
as it reproduces, or “blooms,” releases an oily organic substance responsible for the taste and odor changes to the water during the
summer months. The algae blooms, although aesthetically undesirable to the consumer, do not alter the high quality of treated water
supplies delivered to the City of Melissa by North Texas Municipal Water District. The treated water supply remains safe with no
health hazards created by algae blooms. Through daily monitoring by North Texas Municipal Water District, laboratory personnel can
determine the onset of an algae bloom. When an increase in number of algae develops, additional procedures are taken to reduce the
organic residue during the treatment process.
Country Ridge Water – WS 0430070 3 2015 Consumer Confidence Report (CCR)
Terms to Know TCEQ – Texas Commission on Environmental Quality, the State Agency.
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 wa-
ter. There is convincing evidence that addition of disinfectant is necessary for control of microbial contami-
nants.
Maximum Residual Disinfectant Level 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 disin-
fectants to control 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 re-
quirement which a water system must follow.
NTU – Nephelometric Turbidity Units. This is the unit to measure water turbidity.
Turbidity – A measure of water’s clarity. Turbidity has no health effects; however, turbidity can interfere
with disinfection and provide a medium for microbial growth. Water with lower turbidity is clearer than wa-
ter with higher turbidity.
pCi/L – picocuries per liter ( a measure of radioactivity).
ppm – parts per million, or milligrams per liter (mg/L). One part per million is equal to one drop of red dye
in 26 gallons of water.
ppb – parts per billion, or micrograms per liter. One part per billion is equal to one drop of red dye in
26,000 gallons of water.
ppt – parts per trillion.
THM – Trihalomethanes – a by-product of disinfection of water. Some people who drink water containing
Trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys,
or central nervous system, and may have an increased risk of getting cancer.
HAA – Haloacetic Acid – a by-product of disinfection.
TOC – Total Organic Carbon.
ND – None Detected.
Cysts/L – Cysts per liter

Campbell Scientific Weather Station
The City of Melissa purchased a Campbell Scientific Weather Station in compliance with the TexasET Net-work requirements and the Weather Station was setup by Texas A&M Agrilife Staff in March 2016.
Located at the former Country Ridge Well #2 site near the corner of Fannin Road and Palo Pinto Drive, the weather station is now a part of the TexasET Network sponsored by the North Texas Municipal Water District.
The Benefit to the City is that the Weather station pro-
vides LOCAL weather data for MELISSA to aid our
water customers in determining HOW MUCH and
WHEN they NEED to water their landscape based on
local temperatures, effective rainfall, solar radiation,
relative humidity, and wind.
