Water Quality Report Shows Your Water is Safe

We're pleased to present to you this year's Annual Water Quality Report. This report is

designed to inform you about the quality of the water and services we deliver to you every

day. Our constant goal is to provide you with a safe and dependable supply of drinking

water. We want 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.

Our water source is the Biscayne aquifer, a groundwater supply. In 2011 The Department of Environmental Protection 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. There are three potential sources of contamination identified for this system with moderate susceptibility levels. The

assessment results are available on the FDEP Source Water Assessment and Protection

Program website at www.dep.state.fl.us/swapp or they can be obtained from the City of

Dania Beach. We collect four quarterly well samples per year to test for contaminants

associated with these potential sources of contamination and are in compliance with State

and Federal Regulations. Once the water is pumped from the ground, we treat the water

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 remove microbiological contaminants and fluoride is added to

reduce dental caries. The City added and during November 2011 placed in service a new

Nanofiltration/reverse osmosis membrane process 2-mgd expansion to the City’s existing

3-mgd lime-softening plant. The flows from each process are mixed at approximately

50/50 prior to discharge into the distribution system. We provide water to approximately

17,000 citizens of the City of Dania Beach.

The City of Dania Beach 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, 2011. Data obtained before December 31, 2011, and presented in this

report are from the most recent testing done in accordance with the laws, rules, and

regulations. The state allows us to monitor for some contaminants less than once per year

because the concentrations of these contaminants do not change frequently.

Reading the Water Quality Table

Certain elements present in drinking water occur naturally in the environment, while other

elements appear as a result of the water treatment process. These elements, reported in the

chart below, do not exceed the maximum contaminant level established by EPA.

The Water Quality Table below shows test results that guarantee your water is safe. For

more information, call Dania Beach Water Plant, (Philip Skidmore) (954)924-3747.

Terms and Definitions

In the table below, you may find unfamiliar terms and abbreviations. To help you

better understand these terms we've provided the following definitions:

Action Level (AL): The concentration of a contaminant which, if exceeded, triggers

treatment or other requirements that a water system must follow.

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.

“ND” means not detected and indicates that the substance was not found by

laboratory analysis.

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.

Parts per billion (ppb) or Micrograms per liter (!g/l) – one part by weight of analyte

to 1 billion parts by weight of the water sample

Picocurie per liter (pCi/L) - measure of the radioactivity in water.
