LOOK BEHIND THE HIGHLIGHTS
What was measured in Plant City’s water?
These tables make selected utility records easier to read. Sample dates and comparison types matter: an annual average, a 90th percentile, and a single sample are different measurements. The city’s original documents contain the complete records.
Figures below use the 2024 utility report and 2024–25 monitoring. The city’s newer 2025 report is not represented. These are utility records, not a test at your tap. See current city reports ↗

TTHM’s 74.025 ppb and HAA5’s 48.20 ppb are the highest locational running annual averages. The TTHM single-sample range reached 88.80 ppb; that peak is not the averaging measure used for this comparison.
Open the original 2024 water quality report (PDF) ↗PFAS and other monitoring
All 29 PFAS in the city’s listed 2024–25 monitoring samples were reported as not detected. That means below the method’s reporting level, not necessarily absent. The table below shows selected analytes whose reporting levels are clear in the source.
| Analyte | Listed sample result | Minimum reporting level |
|---|---|---|
| PFOS | Not detected | 0.0039 µg/L |
| PFHxS | Not detected | 0.0030 µg/L |
| PFBA | Not detected | 0.0050 µg/L |
| PFPeA | Not detected | 0.0030 µg/L |
| PFHxA | Not detected | 0.0030 µg/L |
| PFHpA | Not detected | 0.0030 µg/L |
| PFBS | Not detected | 0.0030 µg/L |
| Lithium (not a PFAS) | Not detected | 9.0 µg/L |
A minimum reporting level is a laboratory reporting threshold, not a drinking-water safety limit. See the full monitoring sheet for all 29 PFAS, sampling dates, and plant-level entries.

A few terms, in plain English
- ppm / ppb
- Parts per million / parts per billion. For these water results, 1 ppm = 1 mg/L; 1 ppb = 1 µg/L.
- MCL / MRDL
- A regulated maximum contaminant level / maximum residual disinfectant level. Apply the report’s specified averaging basis.
- Action level
- A utility treatment trigger for lead or copper. It is not a guarantee that every household tap is below that number.
- 90th percentile
- A statistic across sampled taps. It is not a measurement from your home.
- ND
- Not detected at or above the method’s reporting level. It does not mean zero.
- gpg
- Grains per gallon: a hardness unit. About 17.1 mg/L as CaCO₃ equals 1 gpg.

More about your local water
What this means for your home
A report is a useful starting point. Here’s what these results can mean for a Plant City home—and what they cannot tell you.
Hardness is the clearest reason to soften.
The city gives approximate hardness guidance of 180 mg/L as CaCO₃, or 10.5 grains per gallon. That falls in the USGS “hard” range and supports recommending a softener for scale control.
Confirm hardness at your home when programming the softener. A utility estimate is not a substitute for that measurement.
City hardness guidance ↗USGS hardness scale ↗A filter does a different job.
The city identifies chlorine treatment. The 2024 report’s highest running annual average was 1.58 ppm, below its 4.0 ppm report limit.
A suitable filter can reduce chlorine taste and odor. A softener addresses calcium and magnesium hardness; it does not take the filter’s place.
Filter vs. softener: understand the difference →One report doesn’t describe every tap.
Plumbing, service lines, sampling location, and time can affect results. A city report also does not apply to a private well or a different utility.
If lead, a specific contaminant, or a change in your water is your concern, use appropriate tap testing and check the exact treatment model’s verified reduction claim.

A useful local question
Plant City water questions
Does Plant City have hard water?
City guidance puts hardness at approximately 180 mg/L as CaCO₃ (10.5 gpg). USGS classifies 121–180 mg/L as hard. This supports a softener recommendation for scale, with hardness at your home checked for final setup.
Are the amounts in the report high?
Hardness is high enough to fall in the hard-water category. The selected regulated results shown here are below their 2024 report benchmarks, although TTHM’s highest locational annual average is about 93% of its limit. Lead and copper use action levels, and PFAS “not detected” uses reporting thresholds. These are different kinds of comparison—not a single safety score.
Does this show what is coming out of my tap today?
No. These historical utility records describe the city system and sampled locations. They are not a current test of your household water. Check the city’s current report and use appropriate tap testing for home-specific questions.
What about fluoride?
The 0.630 ppm value is a March 2023 sample listed in the 2024 report. The city says it approved ending supplemental fluoride on March 24, 2025, so this older value should not be treated as today’s level. Standard whole-house filtration should not be assumed to remove fluoride; that requires appropriate, verified treatment.
Read the city’s fluoride guidance ↗Does the recommended system remove everything listed?
No single generic claim covers every substance here. This recommendation addresses chlorine taste and odor plus hard-water scale. For lead, PFAS, fluoride, or another specific contaminant, check the exact model’s independently verified reduction claim and suitability for your measured water.
Who installs my water system?
You choose, hire, and pay your own licensed plumber. Your plumber checks the service connection, space, drainage, electrical needs, and local requirements against the selected model’s installation manual.
