This report is available at www.daniabeachfl.gov/ccr. If requested this document
will be mailed to customers.
We’re 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. Our water
source is: wells drawn from the Biscayne Aquifer at a depth of 65 feet.
Source Water Assessment Result
In 2014 the Department of Environmental Protection 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 FDEP Source Water Assessment and Protection
Program website at www.dep.state.fl.us/swapp.
Every year we collect monthly bacteriological samples and four quarterly chemical samples at our
wells to test for contaminants associated with potential sources of ground water. Once the water is
pumped from the ground, we treat it with a process called lime softening. This process precipitates the
calcium and carbonates in the water, making it soft. We then filter the water to remove the remaining
particulates. The water is disinfected to inactivate microbiological contaminants and fluoride is added
to promote dental health. In November 2011, the City added and placed in service a new 2-mgd
Nanofiltration membrane plant to the City’s existing 3-mgd lime-softening plant. The flows from each
process are mixed at approximately 50/50 ratio prior to discharge into the distribution system. We
provide water to over 18,000 citizens of the City of Dania Beach.
This Report Shows Our Water Quality Results and What They Mean
If you have any questions about this report or concerning your water utility, please contact Philip W.
Skidmore at (954) 924-3747. We encourage our valued customers to be informed about their water

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.
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.
Nephelometric Turbidity Unit (NTU): measure of the clarity of water. Turbidity in excess of 5 NTU is
just noticeable to the average person.
“ND”: means not detected and indicates that the substance was not found by laboratory analysis.
“N/A”: means not available or not applicable
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.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking
water.

* On September 9, 2014 we collected a sample from the I well and this sample tested positive for E. coli. In response, the City
of Dania Beach sent notifications to our customers within 24 hours of learning of the positive sample. Both of our production
wells were disinfected according to F.A.C guidelines. Follow-up samples collected on September16 and 17, 2014 in both of the
source water locations (10 samples) and additional distribution samples (22 samples) were satisfactory (no E. Coli or Total
Coliform bacteria were detected).
Health Effects: Fecal coliforms and E. coli are bacteria whose presence indicates that the water may be contaminated with
human or animal wastes. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, or
other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely
compromised immune systems.

Unregulated Contaminants Monitoring Round 3 (UCMR3)
The City of Dania Beach has been monitoring for unregulated contaminants (UCs) as part of a study to
help the U.S. Environmental Protection Agency (EPA) determine the occurrence in drinking water of
UCs and whether or not these contaminants need to be regulated. At present, no health standards (for
example, maximum contaminant levels) have been established for UCs. However, we are required to
publish the analytical results of our UC monitoring in our annual water quality report. If you would
like more information on the EPA’s Unregulated Contaminants Monitoring Rule, please call the Safe
Drinking Water Hotline at (800) 426-4791.

Date

Level Detected Range Draft Reference
Concentration
(ug/L)
Likely Source of Contamination
Chromium, Total (ppb)
03/14 0.067U 0-0.33 100
Naturally-occurring element.
Chromium is used in making steel
and other alloys. Chromium-3 or -6
forms are used for chrome plating,
dyes and pigments, leather tanning,
and wood preservation. Chromium-
3 is an essential nutrient.
Molybdenum (ppb)
03/14
0.33U ND-1.0 40
Molybdenum is a naturally-occurring
element found in ores and present in
plants, animals, and bacteria. Its
commonly used form, molybdenum
trioxide, is used as a chemical reagent.

Strontium (ppb)

0.1U ND - 199
4000

Strontium is a naturally-occurring
element. Historically, the commercial
use of strontium has been in the
faceplate glass of cathode-ray tube
televisions, to block x-ray emissions.
“The reference concentrations are based on publically-available health information found in the following EPA resources:
2012 Drinking Water Standards and Health Advisories, the CCL 3 (Contaminant Candidate List) Information Sheets or the
Human Health Benchmark for Pesticides (HHBPs). The draft reference concentration does not represent an “action level”
nor should the draft reference concentration be interpreted as any indication of an agency intent to establish a future
drinking water regulation for the contaminant at this or any other level. Decisions as to whether or not to regulate the
contaminant in drinking water will continue to be made following the EPA’s Regulatory Determination process.”

**Lead: Lead in drinking water is rarely the sole cause of lead poisoning, but it can add to a person's
total lead exposure. All potential sources of lead in the household should be identified and removed,
replaced or reduced.
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 City of Dania Beach 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 up 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 or at http://www.epa.gov/safewater/lead.
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.
In order 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 Food and Drug
Administration (FDA) regulations establish limits for contaminants in bottled water, which must
provide the same protection for public health.
The Environmental Protection Agency (EPA) requires monitoring of over 80 drinking water
contaminants. Those contaminants listed in the table above are the only contaminants detected in your
drinking water.

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.
The Total Coliform Rule requires water systems to meet a stricter limit for coliform bacteria. Coliform
bacteria are usually harmless, but their presence in water can be an indication of disease-causing
bacteria. When coliform bacteria are found, special follow-up tests are done to determine if harmful
bacteria are present in the water supply. If this limit is exceeded, the water supplier must notify the
public by newspaper, television or radio.
In our continuing efforts to maintain a safe and dependable water supply, it may be necessary to make
improvements in your water system. The costs of these improvements may be reflected in the rate
structure. Rate adjustments may be necessary in order to address these improvements.
Thank you for allowing us to continue providing your family with clean, quality water this year. In
order to maintain a safe and dependable water supply, we sometimes need to make improvements that
will benefit all of our customers. These improvements are sometimes reflected as rate structure
adjustments. Thank you for understanding.
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 microbiological contaminants are available from the
Safe Drinking Water Hotline (800-426-4791).
“We at The City of Dania Beach work around the clock to provide top quality water to every tap that
is both bacteriologically sound as well as aesthetically pleasing,” said Philip W Skidmore. We ask that
all our customers help us protect our water sources, which are the heart of our community, our way of
life and our children’s future.
The City of Dania Beach 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 insuring 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.
