health information for

lead: If present, elevated

levels of lead can cause

serious health problems,

especially for pregnant

women and young chil-

dren. Lead in drinking wa-

ter is primarily from mate-

rials and components as-

sociated with service lines

and home plumbing. The

City of Melissa cannot

control the variety of ma-

terials used in plumbing

components. When your

water has been sitting for

several hours, you can

minimize the potential for

lead exposure by flushing

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

protection strategies

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.


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

More about the Aquifer that feeds the wells

for the Country Ridge Water System…

The WOODBINE AQUIFER is a minor aquifer located in northeast

Texas. The aquifer overlies the Trinity Aquifer and consists of sand-

stone interbedded with shale and clay that form three distinct wa-

ter-bearing zones. The Woodbine Aquifer reaches 600 feet in

thickness in subsurface areas, and freshwater saturated thickness

averages about 160 feet. Water quality and yield vary with the

depth of the aquifer.

The lower zones of the aquifer typically yield the most water,

whereas the upper zone yields limited water that tends to be very

high in iron. In general, water to a depth of 1,500 feet is fresh, containing less than 1,000 milligrams per

liter of total dissolved solids. Water at depths below 1,500 feet is slightly to moderately saline, containing

from 1,000 to 4,000 milligrams per liter of total dissolved solids.

The aquifer provides water for municipal, industrial, domestic, livestock, and small irrigation supplies.

Large water level declines, due to heavy municipal and industrial pumping in the Sherman-Denison

area of Grayson County, have moderated in the past decade as suppliers have switched to surface wa-

ter.


HUMAN SOURCES OF SOURCE WATER POLLUTION

The majority of source water pollution occurs during rain events, when storm water runoff picks up debris, dirt, and

other pollutants and carries the pollutants to area streams, creeks and lakes. Because all storm drains are directly

connected to natural drainage ways with no treatment, anything left on the ground becomes source water pollution.

YOU MAKE THE DIFFERENCE

Pollution Nitrogen and phosphorus and potassium are all nutrients we apply annually to improve our turf. Those

same nutrients grow algae when allowed to enter into our streams, creeks, and lakes.

Source Fertilizing your lawn Pet waste

Solution Strictly follow directions and never use

rain events to “water it in”.

Pick up your pet waste before it dissolves in the rain

and gets washed off into the storm drain.

Pollution Biodegradable means the soap or detergent breaks down into basic elements. But, to do so, the soaps take

oxygen out of the water. Removing oxygen in the water can suffocate fish and wildlife.

Source Washing the car Power-washing pavement

Solution

Take the car to a car wash facility or wash

the car in the yard, where the grass will

capture much of the runoff.

Divert or capture the flow. You can pump the power-

wash water into a container and let it soak into the

ground or put it in the sewer system.

ADDITIONAL HEALTH INFORMATION FOR LEAD : If present, elevated levels of lead can cause serious health problems, especially for pregnant women

and young children. Lead in drinking water is primarily from materials and components associated

with service lines and home plumbing. The City of Melissa is responsible for providing high quality

drinking water, but cannot control the variety of materials used in plumbing components. When you

water has been sitting for several hours, you can minimize the potential for lead exposure by flushing

your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your wate r, you may wish to

have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure i s available from

the ‘Safe Drinking Water’ hotline or at http://www.epa.gov//safewater//lead.

Violations: There were no violations during this CCR year and any previous violations have been corrected in

accordance with TCEQ.



The project involved a significant upgrade to the

city’s water infrastructure, including the

replacement of aging water meters with newer

ones utilizing AMI technology to help improve

water conservation and provide the data

required to better manage water usage and

minimize water loss, not being captured by older

meters.

AMI technology provides automatic, accurate

and consistent water meter reads without the

need for manual meter reads and manual data

entry. This data then feeds into a customer

information system that provides a platform

through which residents can accurately track their water usage,

which may help identify irregular water use such as a leak much

sooner.

The City is very excited about this move as the benefits include

advanced data recording of all water consumption on an hourly

basis, historical consumption data for residents, and leak

detection capabilities.

Learn more about this project and the benefits it offers both

the City and our customers at:

http://www.cityofmelissa.com/AMI_Program.html

Water Loss: Texas Legislature requires the City to file an annual water loss report with the Texas Water Development Board and

to notify customers of the results. This notice is intended to meet the notification requirement.

Water Loss is unaccounted for water produced by the water system. This is the difference between the wa-

ter produced and registered at the customer’s meter. Leaks, line breaks, unmetered fire protection, hydrant

flushing for health and safety, and other activities all contribute to water loss.

The City of Melissa - Country Ridge Water System has approximately 9.7 miles of distribution water lines

serving 212 connections. The City of Melissa - Country Ridge Water System had a total of 1,784,304 gallons

of water loss due to water leaks and unauthorized water usage.

One of the most important tools in accurately measuring water loss and insuring accurate utility billing is the wa-

ter meters throughout the city. The City of Melissa Water Department’s goal is to conform to the American Wa-

ter Works Association (AWWA) accuracy standard of 98.5% to 101.5%. To that end, the City made the in-

vestment into the new AMI system which was installed this past winter.

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.


The mission of the Water Department is to provide the

highest quality product as possible while maintaining a

superior infrastructure to provide continuous service

without interruptions, guaranteeing a clean and safe

environment as well as sustaining a high quality of life.

Opportunity for public comment is available on the second and fourth
