The Manatee County Utilities Department makes a commitment daily to provide the highest quality drinking water to the residents of Manatee County, Sarasota County, and cities served.
- The 2024 Water Usage Report Card presents information on drinking water, water conservation rebate programs, water consumption, water rates, the Cross Connection Control Program, and water conservation.
- The 2024 Water Quality Report represents a summary of the drinking water quality during 2024.
- ADDITIONAL WATER QUALITY INFORMATION: This section provides a summary of additional regulated (secondary) and non-regulated water quality parameters. Although all values fall below the established Maximum Contaminant Levels (MCLs) and are therefore not included in the 2024 Water Quality Summary Report, we’re sharing this information to keep our customers fully informed.
- The Monitoring Data for Unregulated Contaminants information provides information on a series of EPA mandated drinking water tests that occurred in 2018. The results provide the EPA with data to determine if these contaminants need to be regulated in the future to protect public health.
- Manatee County provides drinking water that meets all safety standards and strives to provide drinking water to each tap in our system that is free from unfavorable odor or tastes. Sometimes customers report a mild taste or odor. The Manatee County Water System Odor Fact Sheet_062017 describes some of these concerns, details possible causes, and for some, provides diagnostic procedures that can be performed by homeowners.
IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Monitoring Data for Unregulated Contaminants
The Manatee County Utilities Department sampled the drinking water for a series of thirty unregulated contaminants (U.C.) in 2018 as required by the US Environmental Protection Agency (EPA). U.C. are those that do not have a drinking water standard set by the EPA. The purpose of monitoring for these U.C. is to help the EPA decide whether the contaminants should be regulated in the future to protect public health. As a consumer of drinking water you have the right to know that this data is available.
Samples for the analysis of ten Cyanotoxins (nine Cyanotoxins and one Cyanotoxin group) were collected from the Lake Manatee influent location twice a month for a four month period beginning March 2018 through June 2018. Additionally, samples for the analysis for total organic carbon and bromide, were collected during quarterly sampling from the Lake Manatee influent location to supplement the Haloacetic Acid (HAA) data analysis. All other samples for the analysis of U.C. were collected from the drinking water during quarterly sampling.
Below is a table with the U.C. found during the sampling events in 2018. The results are reported in parts per billion (ppb or micrograms per liter) with the exception of total organic carbon, which is reported in parts per million (ppm or milligrams per liter). Listed below the table is a list of other U.C. that were tested for but not detected. Results in the ‘Level Detected’ column are the computed average of the U.C.
Contaminant and Unit of Measurement | Level Detected | Range of Results |
---|---|---|
manganese (ppb) | 6.0 | 3.8 – 11.3 |
HAA5 (ppb) | 47.5 | 31.4 – 87.9 |
HAABr (ppb) | 14.6 | 10.6 – 65.3 |
HAA9 (ppb) | 55.2 | 11.4 – 101.2 |
total organic carbon (ppm) | 12.9 | 8.7 – 18.4 |
bromide (ppb) | 74.3 | 73.4 – 75.9 |
Other unregulated contaminants that were tested for but not detected include:
total microcystin; microcystin-LA; microcystin-LF; microcystin-LR; microcystin-LY; microcystin-RR; microcystin-YR; nodularin; anatoxin-a; cylindrospermopsin; germanium; alpha-hexachlorocyclohexane; chlorpyrifos; dimethipin; ethoprop; oxyfluorfen; profenofos; tebuconazole; tribufos, 1-butanol; total permethrin (cis- & trans-); 2-methoxyethanol; 2-propen-1-ol; butylated hydroxyanisole; o-toluidine; quinolone

Additional Water Quality Information
The accompanying table lists additional regulated (secondary) and non-regulated parameters that were detected in the finished water during 2021.
No adverse health effects are generally associated with the secondary drinking water contaminants. At considerably higher concentrations than the Maximum Contaminant Levels (MCLs), health implications may exist as well as aesthetic degradation. Note that all maximum values are below the MCLs.
