2021 Annual Drinking Water Quality Report of Geneva Lake Estates Water Treatment Plant
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.
Geneva Lake Estates Water Treatment Plant PWS # 2041320 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 Jan. 1 to Dec. 31, 2021. 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 Jan. 1, 2021 and presented in this report is from the most recent testing done in accordance with the laws,
rules, and regulations.
Our water source is ground water from wells that draw from the Floridan Aquifer. Our water is chlorinated for
disinfection purposes then treated with Aqua-Mag to reduce iron levels. This report shows our water quality
results and what they mean.
In the table below, you may find 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.
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.
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.

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.
In 2021, the Florida Department of Environmental Protection (DEP) performed a Source Water Assessment on
our system and a search of the data sources indicated no potential sources of contamination near our wells. The
assessment results are available on the DEP Source Water Assessment and Protection Program (SWAPP)
website at https://fldep.dep.state.fl.us/swapp/.
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).
