The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 11 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2012 to 2025.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium: Florida’s own results, samples taken from Jan. 6, 2020 to Nov. 26, 2024, with EPA’s 2012 to 2019 file for earlier years.

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

75.1ppb

Highest yearly average, 2020 to 2024

2024 average: 51.3 ppb

Averaged by year, the highest was 75.1 ppb, in 2021, below EPA’s legal limit of 80 ppb. Its highest single sample was 150 ppb. In 2024, the latest year on file, its eight samples averaged 51.3 ppb. EPA judges this limit at each sampling point, and recorded violations for total trihalomethanes (TTHM) at this utility in 2022 and 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 83.1 ppb, in 2015.

50.8ppb

Highest yearly average, 2020 to 2024

Averaged by year, the highest was 50.8 ppb, in 2024, below EPA’s legal limit of 60 ppb. Its highest single sample was 109 ppb. That was also the latest year on file. EPA judges this limit at each sampling point, and recorded violations for haloacetic acids (HAA5) at this utility in 2022, 2023 and 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 58.5 ppb, in 2019, and EPA recorded a violation in 2019.

2024: not found

The highest sample, in 2020, was 0.18 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.2 ppm, in 2015.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Lake Harney Water Association’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Florida’s results run from Jan. 6, 2020 to Nov. 26, 2024.

Testing your own tap

Lake Harney Water Association’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Florida certifies.
