Our Drinking Water

Meets or Exceeds All

Federal (EPA) Drinking

Water Requirements

This report is a summary of

the quality of the water the

City of Melissa provides to

our customers. The analysis

was made by using the data

from the most recent U.S.

Environmental Protection

Agency (EPA) required tests

and is presented in the at-

tached pages. The City of

Melissa hopes this infor-

mation helps you become

more knowledgeable about

what is in your drinking

water.

Source Water Assessment 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 conditions. The

information in this assessment will allow us to focus our source water protection

strategies

onds to 2 minutes before

using water for drinking

or cooking. If you are

concerned about lead in

your water, you may

wish to have your water

tested. Information on

lead in drinking water,

testing methods, and

steps you can take to

minimize exposure is

available from the safe

drinking water hotline at

(800) 426-4791 or

http://www.epa.gov/

safewater/lead.

You may be more vulner-

able than the general

population to certain mi-

crobial contaminants,

such as Cryptosporidium,

in drinking water. Infants,

some elderly or immuno-

compromised such as

those undergoing chemo-

therapy for cancer, those

who have undergone

organ transplants, those

who are undergoing

treatment with steroids,

and people with other

immune system disorders

can be particularly at

risk of infections. You

should seek advice about

drinking water from your

physician or health care

provider. Additional

guidelines and appropri-

ate means to lessen the

risk of infection by Cryp-

tosporidium are availa-

ble from the safe drink-

ing water hotline at

(800) 426-4791.

Required additional

health information for

lead: If present, elevat-

ed levels of lead can

cause serious health

problems, especially for

pregnant women and

young children. Lead in

drinking water is primar-

ily from materials and

components associated

with service lines and

home plumbing. The City

of Melissa cannot control

the variety of materials

used in plumbing compo-

nents. When your water

has been sitting for sev-

eral hours, you can mini-

mize the potential for

lead exposure by flush-

ing your tap for 30 sec-

Where Does Our Drinking Water Come From?

The source of drinking water used by COUNTRY RIDGE WATER is

Groundwater from the Woodbine aquifer located in Collin County. The

WOODBINE AQUIFER is a minor aquifer located in northeast Texas. The

aquifer overlies the Trinity Aquifer and consists of sandstone interbedded

with shale and clay that form three distinct water-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 aq-

uifer 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, industri-

al, 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 water.

The population of the NTMWD service area is expected to more than

double between the years 2010 and 2070 from 1.6 million to an esti-

mated 3.7 million served. To meet future water demands, NTMWD is in

the final stages of the permitting process for the proposed Lower Bois

d’Arc Creek Reservoir in Fannin County, which will eventually provide

120,000 acre-feet of water per year to residents in North Texas. The

projected completion date is 2020.

Conservation and reuse are key strategies in the NTMWD long-range

water supply plan. NTMWD and its Member Cities and customers are

recognized as leaders in water conservation and reuse and have robust

programs and innovative projects to help maximize available supplies.

However, conservation and reuse alone cannot reliably meet our com-

munities’ needs beyond 2021. One-quarter of future supplies must come

from new sources. That new source is the proposed Lower Bois d’Arc

Creek Reservoir. Learn more about this project at:

https://www.ntmwd.com/projects/lower-bois-darc-creek-reservoir/ Lower Bois d’Arc Creek Reservoir

In the higher demand Summer months, Country Ridge water supply may be supplemented with CITY OF MELISSA

surface water which is purchased from North Texas Municipal Water District (NTMWD). NTMWD gets raw water from

Lavon Lake and treats it at the Wylie Water Treatment Plant. Please visit www.ntmwd.com or call NTMWD at

(972) 442.5405 for detailed information on this water source, treatment processes and more.

Possible Contaminants in Sources of Drinking Water The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reser-

voirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves natu-

rally-occurring minerals and, in some cases, radioactive material, and can pickup substances resulting from the

presence of animals or from human activity. Contaminants that may be present in source water include:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, sep-

tic 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 farming.

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, col-

or, and odor problems. The taste and odor constituents are often called secondary constituents and are regulat-

ed by the State of Texas, not the EPA. These constituents are not causes for health concern. Therefore, sec-

ondary contaminants are not required to be reported in this document but they may greatly affect the ap-

pearance and taste of your water.

YOU MAKE THE DIFFERENCE - PROTECT OUR WATERSHED

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.

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.

Lead and Copper

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 wa-

ter is primarily from materials and components associated with service

lines and home plumbing. The City of Melissa is responsible for provid-

ing high quality drinking water, but cannot control the variety of materi-

als 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 water, you may wish to have your water tested. Infor-

mation on lead in drinking water, testing methods, and steps you can take to minimize exposure is available

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

Significant upgrades to the city’s water

infrastructure have been taken over the last two

years including the replacement of all 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. Benefits of this system include advanced data recording of all water

consumption on an hourly basis, historical consumption data for residents, and leak

detection capabilities.

Customers can sign-up for this access and setup customized usage alerts to receive

notification by email and/or text message based on established usage thresholds,

allowing more direct control over their own water usage and subsequent bill.

Put the Power of Data in Your Hands and Sign-up Today!

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 3,111,838 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

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

Water Works Association (AWWA) accuracy standard of 98.5% to 101.5%.

ing evidence that addition of disinfectant is necessary for control of microbial contaminants.

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 disinfectants 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 requirement 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 water 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 ex-

cess 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

TASTE AND ODOR ISSUES/ALGAE BLOOMS:

Taste and odor problems can occur in any lake for a number of reasons, such as al-

gae growth, change in temperature, excessive rainfall, flooding, and drought or dry

weather conditions. The grassy, earthy taste and smell usually occur during the hot

summer months and do not represent any type of health hazard. The NTMWD has

ozonation treatment facilities in operation that should reduce or eliminate taste and

odor issues in the water. Algae blooms are common to surface water supplies in warm climate states like Texas. The algae

blooms, although aesthetically undesirable to the consumer, do not alter the high quality of treated water supplies deliv-

ered to the City of Melissa by North Texas Municipal Water District.

Defend Your Drains! Many products don't belong in your drains (meaning your kitchen drain, toilet drain, bathtub

drain, or any other household drain). These products range from wipes to dental floss and medi-

cines to cleaning products. Do your part to help prevent plumbing problems and to protect the

quality of our lakes, rivers, and streams. Defend your drains, defend your pipes, and defend

your environment by using proper disposal methods.

TRASH IT: Wipes, paper towels, and other items that don't break down in water can clog your

pipes, resulting in sewer backups and expensive repairs. Even items labeled "flushable" can clog

sewer pipes. Defend your drains by disposing of these products in the trash (where they belong)

before they cause unpleasant and expensive problems.

DISPOSE RESPONSIBLY: Medicines. Large amounts of

cleaning products. Paint and pesticides. Fats, oils, and

grease. While all these things shouldn't go down the drain,

they also shouldn't be put in the trash. Why? Some of these

products can pose a hazard to water quality, and others

can be turned into something beneficial.

City of Melissa Weather Station Part of the WaterMyYard Network

The City of Melissa purchased a Campbell Scientific Weather Station in compliance with the

TexasET Network 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

provides 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.
