Tap Into This…Our Water Quality Exceeds National Drinking Water Standards
Broward County Water and Wastewater Services (WWS) is providing this 2007 water quality report to our customers pursuant to requirements set forth by the United States Environmental Protection Agency (EPA). WWS is pleased to report that, in 2007, our water met or exceeded all standards of the federal Safe Drinking Water Act. All of us, have had to adjust our thinking about water being a limitless resource. Here in Florida, where we are almost completely surrounded by water, it is sometimes difficult to appreciate the fact that we are in the midst of a statewide drought which has been ongoing for nearly two years. These record drought conditions demand that we take water conservation seriously and work together to meet the water use restrictions that are currently in effect. These water restrictions are intended to help to stretch limited supplies for our public health and safety and for the region’s economy. In 2007, we marked the second consecutive year of below-average rainfall. Water levels in Lake Okeechobee are at record lows and this is having a significant impact on Broward County, and south Florida as a whole, because, among other things, the Lake is the backup water supply source for more than 5 million people. WWS continues to be actively involved in seeking out ways to not only conserve our existing water resources, but also to develop alternative sources to supplement water supplies for both the short- and long-term. To those ends, WWS is working cooperatively with local, regional and statewide stakeholders to research and further develop those ‘best management practices’ that will ensure the continued viability and sustainability of our area’s water resources. In addition to our vitally important work to develop alternative water resources, we are continuing to explore our options in the areas of water reclamation/reuse; encouraging our customers to use water more efficiently; and, working to revise and amend a water conservation plan that more accurately reflects and responds to both our present and future water supply. We appreciate the conscientious efforts that you, our customers, are making to conserve water. In 2007, we renewed this message of conservation to thousands of students through our annual poetry/poster coloring contest which is conducted in all 138 Broward County elementary schools. This program reinforces the message we seek to share—that it is never too soon to begin thinking about how to preserve and protect one of our most precious resources—water. In the past year, WWS has maintained our commitment to providing the highest quality water to our customers’ taps. We are also ever mindful of our responsibilities to the environmental health of the area. As we work toward finding feasible and cost-effective solutions to the challenges that we face, our primary mission remains unchanged: protection of the public health and safety of our customers through the provision of clean safe drinking water. Thank you for allowing us to be of service to you. Sincerely,

Alan W. Garcia, P.E., Director Water and Wastewater Services.


Before Water Ever Reaches Your Tap, It Goes Through A Multi-Step Treatment Process
How safe is my water?
A review of the 2007 water quality data shows that your drinking water quality meets or exceeds standards set by the United States Environmental Protection Agency (EPA).

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.

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. Dewatered solids are finally hauled away for land application.

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.

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

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 all federal requirements for safe drinking water under the Safe Drinking Water Act. The map on the following page shows the area included in each district’s service area. Tables located on the map page show results of the analyses conducted in 2007 on the finished water supplied by each district.

Biscayne Aquifer
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.

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

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.

Source Water Assessment
The State of Florida Department of Environmental Protection (DEP) has performed a Source Water Assessment on our systems, and a search of the data sources indicated no potential sources of contamination near our wells. The assessment results are available on the DEP Source Water Assessment and Protection Program web site at www.dep.state.fl.us/swapp


*National Environmental Laboratory Accreditation Program (NELAP)Institute/TNI)


Possible Contaminants
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, aquifers, 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) regulates bottled 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 EPA’s Safe Drinking Water Hotline at 800-426-4791.

Immuno-Compromised Persons
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. Environmental Protection Agency/Center for Disease Control guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from EPA’s Safe Drinking Water Hotline at 800-426-4791.


What Is In My Water?
These tables list the parameters set by the Safe Drinking Water Act and the levels detected in potable water for Districts 1A, 2A, 3A, 3B/C and Broadview Park (BV). This report includes data collected during the calendar year 2007. Primary standards related to health, including micro-biological and volatile organics, are listed.

Definitions for the tables

Action Level or AL: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. D/DBP: Disinfectant/Disinfectant By-product and AL - Action Level. Maximum Contaminant Level or MCL: This is the highest level of contaminant that is allowed in water. No MCLs have been exceeded in this year’s testing. 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. Maximum Residual Disinfectant Level or MRDL: The highest level of a disinfectant allowed in drinking water.

Tap Into This….The Water We Have Is the Water We’ve Always Had
Did you know that the same amount of water that exists today on earth existed 3 billion years ago? It is the same water that moves unendingly from sea to clouds to rain to earth and back again. This never-ending journey is referred to as the Water Cycle. During its journey, water is continuously reused and recycled. Because water covers ¾ of the earth’s surface, it might appear that there is plenty to go around. In reality, however, we have a limited amount of usable fresh water. Over 97 percent of earth’s water is found in the oceans as salt water. About two percent of the earth’s water is stored in glaciers, ice caps and snowy mountain ranges. That leaves only 1 percent of fresh water that is readily available to us for our daily water supply needs. The earth’s fresh water supplies are stored either beneath the ground, in soil or fractured bedrock, or in surface waters, such as lakes, rivers and streams. While the total amount of water on earth remains constant, the availability of that water changes with weather (for example drought or flooding), season and human use. In the past, our region has taken water for granted. Today, we realize our economic vitality and way of life are linked to water. We realize we must change our ways and protect our water resources for the future. The picture might look grim, but opportunities to be more efficient abound.

What about the Everglades What about the Everglades, Where wildlife roams free, The sawgrass and the panthers what will their destiny be? What about the Everglades, Where will you see alligators, Will they be hunted or confronted, now or later? What about the Everglades, The source of nature’s power, Will it be knocked down later on and turned into a tower? If we don’t act now, And save what’s left of here, There will be way way much more than just one soggy tear. So please don’t pollute or hunt any animals, Because there is much more in this world, Than just ourselves. By: Andres Rizo 5th Grade Orangebrook Elementary 9

Tap Into This – Reduce Your Water Use…No Excuse!
This section is designed to help you think about how you could make different choices to lessen your impact on the environment. Hopefully, it will help show you that being more environmentally-friendly is possible even in the midst of a busy lifestyle and tight finances. 1. Fix your drips A dripping faucet can waste 20 gallons of water a day. A leaking toilet can use 90,000 gallons of water in a month. Get out the wrench and change the washers on your sinks and showers, or get new washerless faucets. Keeping your existing equipment well maintained is probably the easiest and cheapest way to start saving water. 2. Install new fixtures New, low volume or dual flush toilets, low flow showerheads, water-efficient dishwashers and clothes washing machines can all save a great deal of water and money. Investing in a low-flow toilet could save another 50-80 gallons of water a day. Together, those changes nearly cut in half the household’s daily use, saving a considerable amount of water and money. 3. Cultivate good water habits Try to avoid wasting this precious resource by turning off the water while brushing your teeth or shaving and always wash laundry and dishes with full loads. When washing dishes by hand, fill up the sink and turn off the water. Take shorter showers. To put things in perspective, take a quick look at your next water bill when it arrives. The average household consumes multiple thousands of gallons each month. See if you can make this number go down. 4. Stay off the bottle Bottled water companies’ marketing campaigns that claim bottled water is safer or purer have been enormously successful. The truth is that tap water is actually held to more strict quality standards than bottled water, and some brands of bottled water are just tap water in disguise. What’s more, our increasing use of bottled water—more than 22 gallons per U.S. citizen in 2004 according to the Earth Policy Institute—fuels an unsustainable industry that takes a heavy toll on the environment, including fossil fuel consumption, water consumption and waste. So the next time you feel thirsty, give up the bottle and turn to the tap. You’ll not only lower your environmental impact but also save money—bottled water can cost up to 10,000 times more per gallon than tap water. And because EPA’s standards for tap water are more stringent than FDA’s standards for bottled water, you’ll be drinking water that is just as safe as, or safer than, bottled. If you will be away from home, fill a reusable bottle from your tap and refill it along the way; travel bottles with built-in filters are also available. Finally, limit your bottled water purchases for those times when you’re traveling in countries where water quality is questionable.


5. Rethink your lawn NatureScape it, using native plants that are hardy and don’t need a lot of water. If you have to water, do it during the coolest part of the day or at night to minimize evaporation. For more information on a Florida Friendly Landscape, visit www. broward.org/naturescape 6. Harvest your excess water Water from showers, sprinklers and rain can be used for other jobs. Placing a bucket to catch water in the shower provides water for indoor plants. 7. Use car wash Car washes are often more efficient than home washing because they treat and recycle their water. 8. Keep your eyes open Report broken pipes, open hydrants, and excessive waste. Don’t be shy about pointing out leaks to your friends and family members, either. They might have tuned out the dripping sound a long time ago. 9. Don’t spike the punch Water sources have to be protected. Reducing your fertilizer use will decrease nutrient inputs to our waters and save you money. Instead of blowing grass clippings down the street, you can reduce your need for chemical fertilizers by spreading clippings over your lawn to return nutrients to the soil. Nutrients trapped in organic matter, like grass clippings, leaves, and other organic material can be re-released as pollutants when organic debris enters canals, and lakes. Clippings and leaves can also clog storm drains and culverts and create flooding.
