The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 13 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), arsenic, haloacetic acids (HAA5), chromium (total), fluoride and nitrate: Florida’s own results, samples taken from Feb. 3, 2020 to Aug. 20, 2024, with EPA’s 2012 to 2019 file for earlier years.

Uranium: EPA’s compliance monitoring file, samples taken from July 9, 2012 to July 9, 2012. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

97.3ppb

Highest yearly average, 2020 to 2024

2024 average: 37 ppb

Averaged by year, the highest was 97.3 ppb, in 2020, above EPA’s legal limit of 80 ppb. Its highest single sample was 161 ppb. In 2024, the latest year on file, its two samples averaged 37 ppb. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2020 and 2021. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 146 ppb, in 2017, and EPA recorded violations in 2017, 2018 and 2019.

Above the health goal

1.5ppb

Highest yearly average, 2012

Averaged by year, the highest was 1.5 ppb, in 2012: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file.

What handles it

Below EPA’s limits

35.2ppb

Highest yearly average, 2020 to 2024

2024 average: 11.1 ppb

Averaged by year, the highest was 35.2 ppb, in 2022, below EPA’s legal limit of 60 ppb. Its highest single sample was 41 ppb. In 2024, the latest year on file, its two samples averaged 11.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 108 ppb, in 2017, and EPA recorded a violation in 2017.

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

    For: Total trihalomethanes (TTHM), Arsenic

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

  • NSF/ANSI 58

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

    For: Total trihalomethanes (TTHM), Arsenic, Uranium

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

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), arsenic, haloacetic acids (HAA5), chromium (total), fluoride and nitrate results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Uranium comes from EPA’s file alone, which ends in 2019. Cedar Key WTP’s own annual report, which it must send you every year, has newer results for those and 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 Feb. 3, 2020 to Aug. 20, 2024; EPA’s compliance samples are from July 9, 2012 to July 9, 2012.

Testing your own tap

Cedar Key WTP’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.
