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
call 832-467-1599 or send your comments to:

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.
Maximum residual disinfectant level or
