Mayde Creek MUD

2023 Annual Water

Quality Report Protecting the Water You Drink

In order to ensure that tap water is safe to drink, EPA

prescribes regulations which limit the amount of certain

contaminants in water provided by public water systems. FDA

regulations establish limits for contaminants in bottled water

which must provide the same protection for public health.

Public Participation Opportunities

The Mayde Creek MUD Board of Directors meets regularly

each month typically at 6:00 PM on the 4th Monday of the

month at 19600 Misty Cove, Katy, TX 77449. For more

information regarding the date, time and location of the meeting

Secondary Constituents

Contaminants, such as calcium, sodium or iron, may be found

in drinking water and may cause taste, color, or odor problems.

These types of problems are not necessarily causes for health

concerns.

This report is a summary of the quality of the water we provide

our customers. The analysis was made using data from 2023

EPA required tests (unless noted). The State of Texas allows

us to monitor some substances less than annually because the

concentration does not change frequently. Although the District

samples your water for up to 97 substances we are listing only

those substances detected in your water. The District is

required by the Federal Safe Drinking Water Act to send this

report annually.

For more information on taste, odor, or color of drinking water

please call the District’s Operator, Inframark, at 832-467-1599,

or toll free at 1-866-467-1599 if you have any questions

regarding this report.

Water Sources

The sources of drinking water (both tap 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 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 farming.

• Pesticides and herbicides, which may come from a variety

of sources such as agriculture, urban storm water runoff, and

residential uses.

• 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 water runoff, and septic systems.

• Radioactive contaminants, which can be naturally- occurring or be the result of oil and gas production and mining

activities.

Mayde Creek MUD receives surface water from West

Harris County Regional Water Authority as the primary

source of water. In addition, Mayde Creek MUD has 2

groundwater wells located within Harris County which draw

water from Gulf Coast Aquifers. Mayde Creek MUD also

received water from Ricewood MUD, PWS 1012227,

through an emergency interconnect for approximately 30

days in 2023. The TCEQ completed an assessment of your

source water and results indicate that our sources have a

low susceptibility to contaminants. The sampling

requirements for your water system are based on this

susceptibility and previous sample data. Any detections of

these contaminants may be found in this Consumer

Confidence Report. For more information on source water

assesments and protection efforts at our system, contact

the District Operator at 832-467-1599, or toll free at 1-866-

467-1599. Further details about sources and source-water

assessments are available in the Drinking Water Watch at

the following URL: https://dww2.tceq.texas.gov/DWW/ .

Important Information about 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.

We are responsible for providing high quality drinking water,

but we cannot control the variety of materials used in plumbing

components. When your 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.

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 1-800-426-4791 or at

http://www.epa.gov/safewater/lead.

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 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 at 1-800-426-4791.

Special Notice:

Required language for ALL community public water supplies:

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 1-800-426-4791.

The Board of Directors of Mayde Creek MUD is

pleased to give you this report about your drinking

water based upon 2023 test results.

Our Drinking Water Meets or Exceeds All

Federal (EPA) Drinking Water Requirements.

Definitions - The included tables contain scientific terms and measures, some of which may require explanation.

Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which

a water system must follow.

Avg: Regulatory compliance with some MCLs are based on running annual average of monthly samples.

Level 1 Assessment: A Level 1 assessment is a study of the water system to identify potential problems and determine (if

possible) why total coliform bacteria have been found in our water system.

Level 2 Assessment: A Level 2 assessment is a very detailed study of the water system to identify potential problems and

determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform bacteria

have been found in our water system on multiple occasions.

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.
