2022 Consumer Confidence Report
We are pleased to present the City of Oldsmar’s 2022 Annual Drinking Water Quality Report. This report is designed to inform all City of Oldsmar water customers about the quality of water and the services we deliver to you every day. Our goal is to provide you with a safe and dependable supply of drinking water. This report will help you to understand the efforts made to continually improve the water treatment process and protect our limited water resources.
The City of Oldsmar relies on you, our valued customers, to help in the efforts to conserve our precious water resources. There are many ways to conserve water. Check for leaks, install low flow faucets and shower heads, irrigate only when needed, and use reclaimed water for irrigation if service is available in your neighborhood.
Water is drawn from two brackish aquifers: the Tampa Limestone and the Upper Suwannee. The brackish water is supplied to the Reverse Osmosis Water Treatment Plant by 11 wells located in the city. The drinking water is produced by pumping the brackish water through special filtering membranes primarily removing salts. The water is then processed through a degasification system to remove hydrogen sulfide, pH stabilized, and disinfected before delivery to the Oldsmar residents and businesses. The city also maintains an emergency connection with Pinellas County.
In 2022, the FDEP 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. According to the assessment, there are two potential sources of contamination identified for our system, with a susceptibility level classified as low to moderate.
The potential source of contamination, located in local industries, including petroleum storage and small quantity generator waste. The assessment results are available on the FDEP Source Water Assessment and Protection Program website at www.dep.state.fl.us/swapp or can be obtained from the City of Oldsmar Public Works Department, located at 100 State St. West, Oldsmar, Fl. 34677, or by calling (813) 749-1233.
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. 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.
Contaminants that may be present in source water 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, 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 such as agriculture, 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.
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.
The City of Oldsmar has performed other compliance monitoring tests on its water as required by FDEP and EPA in addition to those reported in the Inorganic, Disinfection by-products, and Lead & Copper in this report. Results of these tests performed were all found to be non-detectable.
Water is critical for sustainable development, including environmental integrity and the alleviation of poverty and hunger, and is indispensable for human health and well-being.

WATER QUALITY ANALYSIS RESULTS
The City of Oldsmar Public Water System 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, 2022, to December 31, 2022. Data obtained before January 1, 2022, and presented in this report are from the most recent testing done in accordance with the laws, rules, and regulations. The following tables refer to the analysis performed on the water in the City of Oldsmar’s Distribution System.

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. The City of Oldsmar Public Water System 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 of 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.
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/Center for Disease Control (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 (800-426-4791).
Additional information can be obtained on the specific tests and their results by contacting the City of Oldsmar at (813) 749-1226.
Action Level (AL) The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.
Initial Distribution System Evaluation (IDSE) – An important part of the Stage 2 Disinfection By-Products Rule (DBPR). The IDSE is a one-time study conducted by water systems to identify distribution system locations with high concentrations of trihalomethanes (THMs) and haloacetic acids (HAAs). Water systems will use results from the IDSE, in conjunction with their Stage 1 DBPR compliance monitoring data, to select compliance monitoring locations for the Stage 2 DBPR.
Maximum Contaminant Level (MCL) – The highest level of a contaminant that is allowed in drinking water. MCL’s are set as close to the MCLG’s 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. MCLG’s allow for a margin of safety.
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. MRDLG’s do not reflect the benefits of the use of disinfectants to control microbial contaminants.
Millirem per year (mrem/yr) – measure of radiation absorbed by the body.
N- No
NA – means not applicable to this contaminant
Parts per billion (ppb) or Micrograms per liter (ug/l) – one part by weight of an analyte to 1 billion parts by weight of the water sample.
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.
Picocurie per liter (pCi/L) – measure of the radioactivity in water.
RDL – Reportable detection level
Treatment Technique (TT) – A required process intended to reduce the level of a contaminant in drinking water.
U – Undetectable
Y - Yes
