Water Quality

Drinking Water

 

What does the utility do to assure my drinking water complies with federal and state standards?

Before water ever reaches your tap, it goes th​rough a multi-step treatment process.

 ​

Where does my water come from?

Your tap water originates from the Biscayne Aquifer, which lies 50-200 feet underground. The Aquifer is comprised primarily of limestone and sand. Recharge is received from rainwater and surface canals.
 

Biscayne Aquifier

As a groundwater source, the Aquifer is naturally protected from undesirable microbial pathogens that are common in surface water supplies. This is due to the natural filtration that occurs in the Aquifer and the amount of time the water resides in the ground prior to being withdrawn.
 

Source Water Assessment

The State of Florida Department of Environmental Protection (FDEP) performed a Source Water Assessment on our systems in 2014. The report(s) indicated no unique potential contaminant sources in District 1A and no unique potential contaminant sources in District 2A. In 2014, FDEP performed a Source Water Assessment for the City of Hollywood which provides water for our 3A and 3B/C systems. The assessment results are available on the FDEP Source Water Assessment Protection Program website at dep.state.fl.us/swapp.
 

Softening

At the water treatment plant, the ground water is initially treated with lime and ferric chloride to reduce hardness and color. During this step of the treatment process, chemicals are added so that most of the hardness and particles in the water can be easily removed.
 

Fluoridation

Following softening, fluoride is added for enhanced protection against tooth decay.
 

Filtration

Filtration is used following softening to further purify the softened water by removing the remaining particulate matter from the treated water.
 

Disinfection

Disinfection, which is the final treatment step, is accomplished by the addition of chlorine and ammonia, otherwise known as chloramines. A small amount (residual levels) of chloramines disinfectant is maintained throughout the distribution system in order to control microbial
regrowth.
 

Dewatering

Solids that settle out during the treatment process are collected and pumped to a settling basin, where they are thickened. The thickened solids are pumped to a vacuum filter, which removes excess water.
 

Monitoring

Water and Wastewater (WWS) has been monitoring for unregulated contaminants (UCs) as part of a study to help the 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.
 
More than 23,000 tests are performed each year to comply with national standards in WWS’ NELAP* certified drinking water laboratory.
 
WWS also employs certified water treatment operators who conduct more than 317,000 process control tests annually. These tests ensure that the water treated and delivered to
Broward County customers meets or exceeds all federal requirements for safe drinking water under the Safe Drinking Water Act.
 
The following provided table lists the parameters set by the Safe Drinking Water Act and the levels detected in potable water for Districts 1A, 2A, 3A and 3B/C. This report includes the results of our monitoring for the period of January 1 to December 31, 2014.  Data obtained before January 1, 2014, and presented in this report, are from the most recent testing done in accordance with drinking water laws, rules and regulations.
