The short answer

3 results are above the health goal. The worst: Lead, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2010 to 2025.

Uranium, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride and chromium (total): Florida’s own results, samples taken from June 1, 2020 to Oct. 23, 2024, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal3

Lead

Comes from pipes, often your own

Above the health goal

3.2ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 3.2 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Uranium

Comes from the source

Above the health goal

1.1ppb

Highest yearly average, 2021 to 2024

2024 average: 0.15 ppb

Averaged by year, the highest was 1.1 ppb, in 2021: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 1.5 ppb. In 2024, the latest year on file, its two samples averaged 0.15 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.65 ppb, in 2018.

What handles it

Arsenic

Comes from the source

Above the health goal

0.2ppb

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.2 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 0.4 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.2 ppb, in 2015.

What handles it

Below EPA’s limits4

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

67.3ppb

Highest yearly average, 2020 to 2024

2024 average: 39.4 ppb

Averaged by year, the highest was 67.3 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2024, the latest year on file, its two samples averaged 39.4 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 77.2 ppb, in 2014.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

16.5ppb

Highest yearly average, 2020 to 2024

Averaged by year, the highest was 16.5 ppb, in 2024, below EPA’s legal limit of 60 ppb. Its highest single sample was 25.1 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 19.7 ppb, in 2019.

Nitrate

Comes from the source

Below EPA’s limits

0.3ppm

Highest sample; found in 7 of 8

2024 average: 0.077 ppm

The highest sample, in 2021, was 0.3 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, its two samples averaged 0.077 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.39 ppm, in 2019.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.057ppm

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.057 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.068 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.17 ppm, in 2012.

What handles it

One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)

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: Lead Reduction, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Lead Reduction, Uranium, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Lead, Uranium, Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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. Uranium, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride and chromium (total) results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Windemere Utility’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 June 1, 2020 to Oct. 23, 2024.

Testing your own tap

Windemere Utility’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.
