The short answer

1 result is above the limit’s level with no violation recorded, and 3 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2006 to 2024.

Total trihalomethanes (TTHM), arsenic, uranium, haloacetic acids (HAA5), nitrate, fluoride and chromium (total): Florida’s own results, samples taken from March 24, 2020 to Oct. 30, 2024, with EPA’s 2012 to 2019 file for earlier years.

Above the limit’s level, no violation recorded1

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the limit’s level, no violation

95.7ppb

Highest yearly average, 2020 to 2024

2024 average: 8.0 ppb

Averaged by year, the highest was 95.7 ppb, in 2021, above EPA’s legal limit of 80 ppb. In 2024, the latest year on file, its four samples averaged 8.0 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 43.1 ppb, in 2019.

Above the health goal3

Arsenic

Comes from the source

Above the health goal

1.1ppb

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 1.1 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 1.2 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.5 ppb, in 2015.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Lead

Comes from pipes, often your own

Above the health goal

0.6ppb

90th percentile, 2024

In the latest period, 9 in 10 homes sampled were at or below 0.6 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

0.99ppb

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.99 ppb, in 2024: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 1.0 ppb. That was also the latest year on file.

What handles it

Below EPA’s limits

29.1ppb

Highest yearly average, 2020 to 2022

2022 average: 7.0 ppb

Averaged by year, the highest was 29.1 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, its 12 samples averaged 7.0 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 33.4 ppb, in 2019.

Nitrate

Comes from the source

Below EPA’s limits

4.8ppm

Highest sample; found in 5 of 7

2024 average: 2.1 ppm

The highest sample, in 2020, was 4.8 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, its two samples averaged 2.1 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 4.8 ppm, in 2018.

What handles it

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

Fluoride

Below EPA’s limits

0.082ppm

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.082 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.09 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, Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Total trihalomethanes (TTHM), Arsenic, Lead, Uranium

    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. Total trihalomethanes (TTHM), arsenic, uranium, 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. Grenelefe Resort’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 March 24, 2020 to Oct. 30, 2024.

Testing your own tap

Grenelefe Resort’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.
