The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the legal limit. 5 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2022 to 2025.

Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, nitrate, arsenic and chromium (total): Florida’s own results, samples taken from Aug. 10, 2020 to Nov. 19, 2024, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit2

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the legal limit

65.6ppb

Highest yearly average, 2022 to 2024

Averaged by year, the highest was 65.6 ppb, in 2024, above EPA’s legal limit of 60 ppb. Its highest single sample was 79 ppb. That was also the latest year on file. EPA recorded a violation for haloacetic acids (HAA5) at this utility in 2024.

Above the legal limit

85.5ppb

Highest yearly average, 2022 to 2024

Averaged by year, the highest was 85.5 ppb, in 2024, above EPA’s legal limit of 80 ppb. Its highest single sample was 130 ppb. That was also the latest year on file. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2023, 2024, 2025 and 2026.

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

2.0ppb

90th percentile, 2025

In the latest period, 9 in 10 homes sampled were at or below 2.0 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.

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.18ppm

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.18 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.2ppm

Highest sample; found in 1 of 5

2024, one sample: 0.2 ppm

The highest sample, in 2024, was 0.2 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 0.2 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.25 ppm, in 2015.

What handles it

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

  • Arsenic
  • 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: 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. Haloacetic acids (HAA5), total trihalomethanes (TTHM), fluoride, nitrate, arsenic and chromium (total) results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Lake Toho 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 Aug. 10, 2020 to Nov. 19, 2024.

Testing your own tap

Lake Toho 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.

No lab Florida certifies is within 75 miles of the area Lake Toho Resort serves on the state’s list. Some take samples by mail; the state’s page lists them all.

Florida Department of Health Bureau of Public Health Laboratories: Coliform and E. coli testing for private wells at the Jacksonville and Miami labs. Collection kits come from your county health department, and the sample has to reach the lab on ice the same day it is collected. $40 for private testing through the state lab.
