The short answer

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

What handles it

What was found

Uranium, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, nitrate and chromium (total): Florida’s own results, samples taken from Jan. 7, 2020 to July 9, 2024, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Uranium

2024 average: 0.67 ppb

Averaged by year, the highest was 0.99 ppb, in 2022: 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 three samples averaged 0.67 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.4 ppb, in 2012.

Arsenic

Comes from the source

Above the health goal

0.13ppb

Highest yearly average, 2020 to 2024

2024: not found

Averaged by year, the highest was 0.13 ppb, in 2020: below EPA’s legal limit of 10 ppb, but above its health goal of zero. Its highest single sample was 0.2 ppb. In 2024, the latest year on file, it wasn’t found in any of its three samples. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.65 ppb, in 2016.

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

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

    For: Uranium, Arsenic

    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. Uranium, arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, nitrate and chromium (total) results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Tampa Bay Water Reg. Surface Water Plant’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. 7, 2020 to July 9, 2024.

Testing your own tap

Tampa Bay Water Reg. Surface Water Plant’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 Tampa Bay Water Reg. Surface Water Plant 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.
