About Your Water Utility
Orange County Utilities’ water system continues to provide reliable service to a growing number of customers in Orange County. In 2016, the Orange County Utilities Water Division provided quality water service to over 145,000
accounts, serving a population of more than 493,500. We produced 21.9 billion gallons of water in our 3 regional water facilities and 8 smaller facilities. The water was distributed through 1,846 miles of water mains throughout the 451 square mile service area.
Well pumps at Orange County’s water supply facilities draw water from a natural underground reservoir called the Floridan Aquifer. After the sulfide is removed, it is treated with chlorine, fluoride is added, and the water is pumped to a finished water tank, awaiting distribution to residential, commercial, and industrial customers.
Your Water Supply Source
Beneath Orange County lies a freshwater reservoir known as the Floridan Aquifer. The groundwater
from this aquifer is of consistently high quality and is used as a source of potable water for our systems and other systems in this area. It is primarily fed by rainwater that is filtered through hundreds of feet of sand and rock in a natural filtering process. Because of its high quality, the groundwater we use needs little or no treatment other than disinfection and aeration to remove naturally present hydrogen sulfide.

Understanding Your Water Quality ReportThe water distributed to the homes of our customers is regularly monitored by state-certified operators and analyzed by our laboratory to ensure compliance with state and federal drinking water standards, thus providing the highest quality water. Our commitment to water quality is reflected by more than 350,000 analyses performed during 2016, which is far above the required testing. The Orange County Utilities Water Division monitors for more than 150 substances in the drinking water supply. Orange County water systems are monitored on different cycles ranging from monthly to every three years according to state and federal laws, rules, and regulations. Except where indicated otherwise, this report is based on results of our monitoring for the period of January 1 - December 31, 2016.
Two samples during 2016 had Total Trihalomethane results of 85.2 and 82.7 ppb, which exceeds the MCL of 80 ppb. However, the system did not incur an MCL violation because all locational annual average results at all sites were at or below the MCL. Some people who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.
The Table Contains:• The name of each contaminant• The unit of measurement• The highest level allowed by regulation (MCL)• The ideal goal for public health (MCLG or MRDLG)• The amount of contaminant detected and the likely source of the contaminant
Key to Abbreviations:AL - Action Level is the concentration of a contaminant that, if exceeded, triggers treatment or other requirements which a water system must follow.MCL - Maximum Contaminant Level is 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.MCLG - Maximum Contaminant Level Goal is 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.MRDLG - Maximum Residual Disinfectant Level Goal is 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.MRDL - Maximum Residual Disinfectant Level is 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.
NA - Not Applicable.pCi/L - Picocuries Per Liter - Measure of the radioactivity in water.ppb - Parts Per Billion or micrograms per liter - one part by weight of analyte to 1 billion parts by weight of water sample.ppm - Parts Per Million or milligrams per liter - one part by weight of analyte to 1 million parts by weight of water sample.
Footnotes to Water Quality Test Results
1. The Florida Department of Environmental Protection (FDEP) standard for Sodium is 160 ppm. The FDEP has set the MCL for Sodium at a more stringent level than federal regulations require.
2. For the parameters monitored under the Stage 2 D/DBP regulations, the level detected is the highest locational running annual average for the samples collected: Haloacetic Acids (60 ppb) and/or TTHM (MCL 80 ppb). Range of Results is the range of results (lowest to highest) at the individual sampling sites.

Assurance of Healthy Drinking Water
The Environmental Protection Agency (EPA) requires all public water suppliers to routinely
monitor for contaminants in the drinking water according to federal and state laws. The state allows us to monitor less than once per year because the concentrations of these contaminants do not change frequently. 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 EPA Safe Drinking Water Hotline at 800-426-4791.
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 that must provide the same protection for public health.
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.
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 for infections. These people should seek advice about drinking water from their health care providers. EPA and the Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the EPA Safe Drinking Water Hotline at 800-426-4791.
Contaminants That May Be Present in the SourceWater Include:• Microbial contaminants, such as viruses and bacteria,
which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
• 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.
• Pesticides and herbicides, which may come from a variety of sources, urban stormwater runoff, and residential uses.
• 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.
• Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.

Some More Specific Information About Lead
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. Orange County Utilities 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 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 your exposure is available from the EPA Safe Drinking Water Hotline at 800-426-4791 or at www.epa.gov/safewater/lead.
Source Water Assessment andProtection Program (SWAPP)
SWAPP stands for Source Water Assessment and Protection Program. This program is meant to ensure that your drinking water is safe, not just at the tap, but at its source. The Florida Department of Environmental Protection
(FDEP) initiated SWAPP as part of the federal Safe Drinking Water Act (SDWA). Lakes, rivers, streams, and aquifers make up the drinking water sources in Florida. These source waters can be threatened by potential contaminants such as hazardous chemicals, stormwater runoff, waste disposal sites, and underground storage tanks. It is a national priority to protect these sources and ensure safe drinking water for citizens. SWAPP was created to protect these vital resources.
FDEP completed the initial baseline study for our water systems in 2004 and updated the study in 2016. The results are posted on the SWAPP website (www.dep.state.fl.us/swapp). Since initial evaluation is based on existing databases, FDEP can only make preliminary and tentative evaluations. Changes that are reported can help update the databases and provide timely information. Community members can help by reviewing the information and reporting any discrepancies that are identified.

Assurance of Healthy Drinking Water
The Environmental Protection Agency (EPA) requires all public water suppliers to routinely
monitor for contaminants in the drinking water according to federal and state laws. The state allows us to monitor less than once per year because the concentrations of these contaminants do not change frequently. 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 EPA Safe Drinking Water Hotline at 800-426-4791.
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 that must provide the same protection for public health.
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.
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 for infections. These people should seek advice about drinking water from their health care providers. EPA and the Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the EPA Safe Drinking Water Hotline at 800-426-4791.
Contaminants That May Be Present in the SourceWater Include:• Microbial contaminants, such as viruses and bacteria,
which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
• 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.
• Pesticides and herbicides, which may come from a variety of sources, urban stormwater runoff, and residential uses.
• 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.
• Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.

Some More Specific Information About Lead
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. Orange County Utilities 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 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 your exposure is available from the EPA Safe Drinking Water Hotline at 800-426-4791 or at www.epa.gov/safewater/lead.
Source Water Assessment andProtection Program (SWAPP)
SWAPP stands for Source Water Assessment and Protection Program. This program is meant to ensure that your drinking water is safe, not just at the tap, but at its source. The Florida Department of Environmental Protection
(FDEP) initiated SWAPP as part of the federal Safe Drinking Water Act (SDWA). Lakes, rivers, streams, and aquifers make up the drinking water sources in Florida. These source waters can be threatened by potential contaminants such as hazardous chemicals, stormwater runoff, waste disposal sites, and underground storage tanks. It is a national priority to protect these sources and ensure safe drinking water for citizens. SWAPP was created to protect these vital resources.
FDEP completed the initial baseline study for our water systems in 2004 and updated the study in 2016. The results are posted on the SWAPP website (www.dep.state.fl.us/swapp). Since initial evaluation is based on existing databases, FDEP can only make preliminary and tentative evaluations. Changes that are reported can help update the databases and provide timely information. Community members can help by reviewing the information and reporting any discrepancies that are identified.

About Your Water Utility
Orange County Utilities’ water system continues to provide reliable service to a growing number of customers in Orange County. In 2016, the Orange County Utilities Water Division provided quality water service to over 145,000
accounts, serving a population of more than 493,500. We produced 21.9 billion gallons of water in our 3 regional water facilities and 8 smaller facilities. The water was distributed through 1,846 miles of water mains throughout the 451 square mile service area.
Well pumps at Orange County’s water supply facilities draw water from a natural underground reservoir called the Floridan Aquifer. After the sulfide is removed, it is treated with chlorine, fluoride is added, and the water is pumped to a finished water tank, awaiting distribution to residential, commercial, and industrial customers.
Your Water Supply Source
Beneath Orange County lies a freshwater reservoir known as the Floridan Aquifer. The groundwater
from this aquifer is of consistently high quality and is used as a source of potable water for our systems and other systems in this area. It is primarily fed by rainwater that is filtered through hundreds of feet of sand and rock in a natural filtering process. Because of its high quality, the groundwater we use needs little or no treatment other than disinfection and aeration to remove naturally present hydrogen sulfide.

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. Orange County Utilities 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 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 your exposure is available from the EPA Safe Drinking Water Hotline at 800-426-4791 or at www.epa.gov/safewater/lead.
Source Water Assessment andProtection Program (SWAPP)
SWAPP stands for Source Water Assessment and Protection Program. This program is meant to ensure that your drinking water is safe, not just at the tap, but at its source. The Florida Department of Environmental Protection
(FDEP) initiated SWAPP as part of the federal Safe Drinking Water Act (SDWA). Lakes, rivers, streams, and aquifers make up the drinking water sources in Florida. These source waters can be threatened by potential contaminants such as hazardous chemicals, stormwater runoff, waste disposal sites, and underground storage tanks. It is a national priority to protect these sources and ensure safe drinking water for citizens. SWAPP was created to protect these vital resources.
FDEP completed the initial baseline study for our water systems in 2004 and updated the study in 2016. The results are posted on the SWAPP website (www.dep.state.fl.us/swapp). Since initial evaluation is based on existing databases, FDEP can only make preliminary and tentative evaluations. Changes that are reported can help update the databases and provide timely information. Community members can help by reviewing the information and reporting any discrepancies that are identified.

About Your Water Utility
Orange County Utilities’ water system continues to provide reliable service to a growing number of customers inOrange County. In 2016, the Orange County Utilities Water Division provided quality water service to over 145,000
accounts, serving a population of more than 493,500. We produced 21.9 billion gallons of water in our 3 regional water facilities and 8 smaller facilities. The water was distributed through 1,846 miles of water mains throughout the 451 square mile service area.
Well pumps at Orange County’s water supply facilities draw water from a natural underground reservoir called the Floridan Aquifer. After the sulfide is removed, it is treated with chlorine, fluoride is added, and the water is pumped to a finished water tank, awaiting distribution to residential, commercial, and industrial customers.
Your Water Supply Source
Beneath Orange County lies a freshwater reservoirknown as the Floridan Aquifer. The groundwater
from this aquifer is of consistently high quality and is used as a source of potable water for our systems and other systems in this area. It is primarily fed by rainwater that is filtered through hundreds of feet of sand and rock in a natural filtering process. Because of its high quality, the groundwater we use needs little or no treatment other than disinfection and aeration to remove naturally present hydrogen sulfide.

Understanding Your Water Quality ReportThe water distributed to the homes of our customers is regularly monitored by state-certified operators and analyzed by our laboratory to ensure compliance with state and federal drinking water standards, thus providing the highest quality water. Our commitment to water quality is reflected by more than 350,000 analyses performed during 2016, which is far above the required testing. The Orange County Utilities Water Division monitors for more than 150 substances in the drinking water supply.
Orange County water systems are monitored on different cycles ranging from monthly to every three years according to state and federal laws, rules, and regulations. Except where indicated otherwise, this report is based on results of our monitoring for the period of January 1 - December 31, 2016.

Assurance of Healthy Drinking Water
The Environmental Protection Agency (EPA)requires all public water suppliers to routinely
monitor for contaminants in the drinking water according to federal and state laws. The state allows us to monitor less than once per year because the concentrations of these contaminants do not change frequently. 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 EPA Safe Drinking Water Hotline at 800-426-4791.
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 that must provide the same protection for public health.
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.
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 for infections. These people should seek advice about drinking water from their health care providers. EPA and the Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the EPA Safe Drinking Water Hotline at 800-426-4791.
Contaminants That May Be Present in the SourceWater Include:• Microbial contaminants, such as viruses and bacteria,
which may come from sewage treatment plants, septicsystems, agricultural livestock operations, and wildlife.
• Inorganic contaminants, such as salts and metals, whichcan be naturally occurring or result from urban stormwaterrunoff, industrial or domestic wastewater discharges, oiland gas production, mining, or farming.
• Pesticides and herbicides, which may come from a varietyof sources, urban stormwater runoff, and residential uses.
• Organic chemical contaminants, including synthetic andvolatile organic chemicals, which are by-products ofindustrial processes and petroleum production, and canalso come from gas stations, urban stormwater runoff,and septic systems.
• Radioactive contaminants, which can be naturallyoccurring or be the result of oil and gas production andmining activities.

Since initial evaluation is based on existing databases, FDEP can only make preliminary and tentative evaluations. Changes that are reported can help update the databases and provide timely information. Community members can help by reviewing the information and reporting any discrepancies that are identified.
