2022 Water Quality Report
CONSUMER CONFIDENCE REPORT
Clay County Utility Authority is very
pleased to provide you with this
year's Annual Water Quality Report.
We want to keep you informed about
the excellent water and services we
have delivered to you over the past
year. Our goal is and always has
been, to provide to you a safe and
dependable supply of drinking water.
CCUA routinely monitors for contaminants in your drinking water
according to federal and state laws, rules, and regulations.
Except where indicated otherwise, this report is based on the
results of our monitoring for the period of January 1 to
December 31, 2022.
The state allows us to monitor for some contaminants less than
once per year because the concentrations of these
contaminants do not change frequently. Some of our data,
though representative, are more than one-year old. Data
obtained before January 1, 2022, and presented in this report
are from the most recent testing done in accordance with the
laws, rules, and regulations.
This report is also available at CCUA’s Administrative Building located at 3176 Old Jennings Road,
Middleburg, FL 32068 upon request. We at CCUA would like you to understand the efforts we make to
continually improve the water treatment process and protect our water resources. We are committed to
ensuring the quality of your water. If you have any questions or concerns about the information provided,
please feel free to call any of the numbers listed.
If you have any questions about this report or concerning your water utility, please contact Heather Webber
at 904-213-2435 or hwebber@clayutility.org. We encourage our valued customers to be informed about
their water utility. If you want to learn more, please attend any of our regularly scheduled meetings. They
are held on the first and third Tuesdays of every month at 2:00pm in the Board Room of the CCUA
Administrative Building at 3176 Old Jennings Road, Middleburg, Florida, 32068. You can also obtain
additional information from EPA at their Safe Drinking Water Hotline (800-426-4791).
System, Source, and Treatment Information
All water treatment plants (WTPs) water sources are ground water wells that draw from the Florida
Aquifer.
All WTPs are chlorinated for disinfection purposes. The following WTPs are aerated for odor
removal: Orange Park Grid, Pace Fleming Grid, Lake Asbury Grid, Keystone Postmaster Grid, and
Ravines. Geneva Lakes Estate is also treated with Aqua-Mag to reduce iron levels.
Grid systems are WTPs that are connected by piping and are considered one system.

Source Water Assessment and Protection
Program
In 2022, the Florida Department of Environmental
Protection (FDEP) performed a Source Water
Assessment on our system. The assessment was
conducted to provide information about any potential
sources of contamination in the vicinity of our wells. The
assessment results are available on the FDEP Source
Water Assessment and Protection Program (SWAPP)
website at https://prodapps.dep.state.fl.us/swapp/ or
they can be obtained from Heather Webber at 904-213-
2435 or hwebber@clayutility.org.
Water Treatment Process
Groundwater from the Floridan Aquifer (1) is drawn by the well pumps (2) and is directed to the
aerators (3) for odor removal. Water is then leaves the aerator and is chlorinated (4) before
entering the storage tanks (5). From the storage tanks, when needed, water will be pumped out by
the high service pumps (6) for distribution to homes, businesses, and restaurants (7).
Unfamiliar Terms and Abbreviations
TO HELP YOU BETTER UNDERSTAND THESE TERMS WE'VE PROVIDED THE FOLLOWING DEFINITIONS
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.
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must
follow.
Locational Running Annual Average (LRAA): The average of sample analytical results for samples taken at a particular monitoring location
during the previous four calendar quarters.
Maximum Residual Disinfectant Level or MRDL: The highest level of a disinfectant allowed in drinking water. There is convincing evidence that
addition of a disinfectant is necessary for control of microbial contaminants.
Maximum Residual Disinfectant Level Goal or 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.
‘ND’ means not detected and indicates that the substance was not found by laboratory analysis.
Parts per billion (ppb) or micrograms per liter (µg/l): one part by weight of analyte to 1 billion parts by weight of the water sample.
Parts per million (ppm) or milligrams per liter (mg/l): one part by weight of analyte to 1 million parts by weight of the water sample.

Likely Source of Contamination
Lead and Copper
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. Clay County Utility Authority is responsible for providing high quality drinking water but
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 two 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 or at http://www.epa.gov/safewater/lead.

Likely Source of Contamination
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 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
include:
(A) Microbial contaminants, such as viruses and
bacteria, which may come from sewage
treatment plants, septic systems, agricultural
livestock operations, and wildlife.
(B) Inorganic contaminants, such as salts and
metals, which can be naturally occurring or
result from urban stormwater runoff,
industrial or domestic wastewater
discharges, oil and gas production, mining,
or farming.
(C) Pesticides and herbicides, which may come
from a variety of sources such as agriculture,
urban stormwater runoff and residential uses.
(D) 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 stormwater
runoff, and septic systems.
(E) Radioactive contaminants, which can be
naturally occurring or be the result of oil and
gas production and mining activities.
To ensure that tap water is safe to drink, the
EPA prescribes regulations, which limit the
amount of certain contaminants in water
provided by public water systems. The U.S.
Food and Drug Administration (FDA) regulations
establish limits for contaminants in bottled water,
which must provide the same protection for
public health.
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
the water poses a health risk. More information
about contaminants and potential health effects
can be obtained by calling the Environmental
Protection Agency’s Safe Drinking Water Hotline
at 1-800-426-4791.
Some people may be more vulnerable to
contaminants in drinking water than the general
population. Immuno-compromised persons such
as persons with cancer undergoing
chemotherapy, persons who have undergone
organ transplants, people with HIV/AIDS or other
immune system disorders, some elderly, and
infants can be particularly at risk from infections.
These people should seek advice about drinking
water from their health care providers. U.S.
Environmental Protection Agency/Center for
Disease Control guidelines on appropriate
means to lessen the risk of infection by
Cryptosporidium and other microbiological
contaminants are available from the Safe
Drinking Water Hotline (800-426-4791).
