Lake Washington provides a surface water supply for the Melbourne area.

Water pumped from Lake Washington is treated at the John A. Buckley Surface Water Treatment Plant.

The Joe Mullins Reverse Osmosis Water Treatment Plant was put into operation in 1995 and processes water drawn from deep wells. 

City of Melbourne's Annual Drinking Water Quality Report 
We are pleased to report that your water is safe and your utility is in compliance with all  state and federal regulations. Please review our annual drinking water quality report that includes the results of water quality testing during the previous calendar year. The report will inform you about the high-quality water and services we deliver.  Our constant goal is to provide you with a safe and dependable supply of drinking water. 

Melbourne's Water Sources 
Our water supply is derived from two independent sources, Lake Washington, and the Floridan Aquifer. 

Lake Washington Lake Washington is part of the St. Johns River, the largest river in Florida. Lake Washington is approximately four miles long, and mile wide, and 10 to 15 feet deep. Lake Washington is one of the few surface water supplies used for drinking water in Florida.  

Floridan Aquifer  The Floridan Aquifer is an extensive underground water source that covers some 82,000 square miles. Melbourne’s reverse osmosis water treatment plant is supplied by three Floridan Aquifer system wells. The wells are approximately 650 to 900 feet deep. Brackish water from the Floridan Aquifer is treated with a reverse osmosis filtering process to remove salts and impurities.  

Water Is Blended -- The water from Lake Washington, which is treated through the Actiflo process and then filtered, is blended with treated reverse osmosis water.  Chloramine booster stations in the water distribution system ensure that adequate levels of disinfectant are maintained throughout the system. Melbourne now has a peak capacity of 26.5 MGD. On a typical day, demand for water is about 15.5 MGD. 

The City of Melbourne has a diversified water-supply approach, using both groundwater and surface water to make sure high-quality water is always available when needed. 

Source Water Assessments
The Florida Department of Environmental Protection (FDEP) has performed a Source Water Assessment on our system.  This assessment was conducted to provide information about any potential sources of contamination in the vicinity of our wells and surface water intakes.  Potential sources of contamination identified include underground petroleum storage tanks, dry cleaning facilities, and domestic wastewater sites.  The assessment results are available on the FDEP Source Water Assessment and Protection website.

Water Quality Test Results
Our state-certified laboratory continuously analyzes water quality throughout the treatment process to ensure superior quality drinking water is delivered to our customers.. The table contained in the annual water quality report shows the results of our monitoring for the period of January 1 to December 31 of the previous year, as well as what the results mean. The state allows us to sample for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Because of this, some of the data, though representative, is more than one year old. 

Melbourne’s Water Quality is Continuously Monitored
In Melbourne’s state-certified water quality laboratory, professional technicians perform tens of thousands of chemical and bacteriological tests on water samples each year. The results of this rigorous testing continually confirm that Melbourne’s water is safe to drink.   We are pleased to report that our drinking water meets all federal and state requirements.

EPA Statements About Water Sources and Contaminants
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 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, 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.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of these 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. 

Individuals May Be More Susceptible to Contaminants
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 (1-800-426-4791). 

Treated Water Quality Terms to Know
In the table below, you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms, please refer to the following definitions: 

Maximum Contaminant Level (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 (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 which a water system must follow.

Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.

Maximum residual disinfectant level (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 (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 million (ppm): 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.

Nephelometric Turbidity Units (NTU): Measurement of the clarity, or turbidity, of water.  Turbidity in excess of 5 NTU is just noticeable to the average person.

Picocuries per liter (pCi/L):. A measure of the radioactivity in water.

N/A: Not applicable
