Involved: Please get involved with discussions regarding drinking
water quality. The Manatee County Board of County Commissioners welcomes
written comments or public input at regularly scheduled Board Meetings
concerning issues related to drinking water. Agenda information can be obtained
on the Manatee County website or by calling 941-745-3724.
Attention
Property Managers: If
you are a property owner or manager, please provide this water quality report
to your tenants. This report may be photocopied or posted in a prominent
location at your facility. Printed copies are available by calling (941) 723-4580.
The
Bottom Line: Last year, as in years past, Manatee County met all EPA and
State drinking water health standards. The Manatee County Water Purification
Plant uses what is known as the multiple barrier approach to ensure the safety
of the water. This approach includes source protection, optimized particle
removal at the purification plant and appropriate disinfection.
2019 Drinking
Water Quality Summary
Manatee County
Utilities Department makes a commitment daily to provide the highest quality
drinking water to the residents of Manatee County, Sarasota County and cities
served. This report reflects on that
commitment and represents a summary of the drinking water quality during 2019.
PROTECTING MANATEE
COUNTY’S WATER SOURCES…
Drinking water
for the customers of Manatee County Utilities Department is a blend of purified
groundwater and purified surface water.
In 2019, an average of 16.32 million gallons per day of deep ground
water and 25.87 million gallons per day of surface water was used.
The
groundwater is pumped from the Floridan Aquifer from seven, 1200-foot deep
wells located in eastern Manatee County.
This water is pumped through a 36-inch pipe approximately 13 miles to
the Purification Plant. Surface water is
taken from the Lake Manatee Reservoir located in central Manatee County.
In 2018, 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 or surface water intakes. There are twelve potential sources of
contamination identified for the Manatee County Water Purification Plant with
susceptibility levels of low and high.
The assessment results are available on the FDEP Source Water Assessment
and Protection Program website www.dep.state.fl.us/swapp or they can be
obtained from the Manatee County Water Purification Plant at (941) 746-3020.
The County has
taken stringent measures to protect these water sources. In the late 1980s, Manatee County voters
approved the purchase of 20,500 acres of the 82,000-acre watershed area, which
drains into and includes the Reservoir and Wellfield. County and State agencies have continued to
purchase additional watershed acreage, and today approximately 35,000 acres are
in public ownership. This ownership
ensures that activities detrimental to water quality or quantity will not occur
on these public lands.
HEALTH
AND SAFETY STANDARDS…
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, EPA prescribes regulations, which limit the amounts
of certain contaminants in water provided by public water systems. The 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.
HOW
YOUR WATER IS PURIFIED…
The Manatee
County Water Purification Plant, located on the shore of Lake Manatee, purifies
both groundwater and surface water. The
groundwater is purified by aeration, lime-softening, and filtration. These processes remove odor, a portion of the
hardness, and undesirable elements such as suspended matter and microbiological
organisms.
The surface
water is purified by carbon adsorption, coagulation, sedimentation, and
filtration. These processes remove odor,
color, and undesirable elements such as suspended matter and microbiological
organisms. The filtered water from the
two sources is then combined. The
combined water is further enhanced before leaving the plant.
The water is
disinfected to destroy microbes and provide protection against microbial
regrowth in the distribution system and your plumbing. The water is also made less corrosive, thus
prolonging your home plumbing and fixtures.
Natural fluoride levels are slightly increased to optimal levels as a
public health measure to help develop decay resistant teeth and strong bones.
The
purification plant is staffed with dedicated, professionally trained, State
certified operational, laboratory and maintenance personnel. This staff operates and maintains the
advanced water purification facility as well as monitors and researches water
quality issues.

Action
Level or AL: The concentration of a contaminant which, if
exceeded, triggers treatment or other requirements which a water system must
follow.
Filter
Turbidity (NTU): Turbidity is a measure of the cloudiness
of the water. We monitor it because it is a good indicator of the effectiveness
of our filtration system. High turbidity can hinder the effectiveness of
disinfectants.
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 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.
Total
trihalomethanes: Disinfection by-products expressed as
the sum of chloroform, dibromochloromethane, bromodichloromethane and
tribromomethane.
Not
Detected or ND: Indicates
the substance was not found by laboratory analysis.
Treatment
Technique or TT: A required process
intended to reduce the level of a contaminant in drinking water.
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. The Manatee
County Water Purification Plant 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
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
at http://www.epa.gov/safewater/lead.
IMMUNO-COMPROMISED
INDIVIDUALS
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. EPA/CDC guidelines on
appropriate means to lessen the risk of infection by Cryptosporidium and other
microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791). These precautions apply to publicly supplied
water, bottled water, private well water, or water from home treatment devices.
FIND
OUT THE FACTS
Concerns about
drinking water quality have caused many residents to use bottled water or to
install home treatment devices. Be sure
to learn about the quality of the alternate water or the expected water quality
from home treatment devices.
Additional
information can be found on the Manatee County website (http://www.mymanatee.org/water).

ADDITIONAL WATER QUALITY INFORMATION (2019)
The
accompanying table lists additional regulated (secondary) and non-regulated
parameters that were detected in the finished water during 2019.
No adverse health effects are generally associated with the
secondary drinking water contaminants. At considerably higher concentrations
than the Maximum Contaminant Levels (MCLs), health implications may exist as
well as aesthetic degradation. Note that
all maximum values are below the MCLs.
