Summary
PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.
Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.
- PFAS
- Above limitPFOA, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 11.3 ppt vs a limit of 4 ppt, PFOS 33.3 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level1 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Dec 2025. Your home's pipes can make yours higher.
- Violations
- None health-basedNo health-based violations since 2016.
- Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
- To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
- Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
- Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
- Read Lantana Water Treatment Plant's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (561) 540-5764. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Apr 2023 to Apr 2024. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.
| Contaminant | Highest average |
|---|---|
| PFOA Above limit Limit 4 ppt | 11.3 ppt 2.82× the limit |
| PFOS Above limit Limit 4 ppt | 33.3 ppt 8.34× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 7.3 ppt 73% of the limit |
| PFNA Detected, below limit Limit 10 ppt | 6.5 ppt 65% of the limit |
| HFPO-DA (GenX) Not detected Limit 10 ppt | – |
| Hazard Index (a combined score for PFHxS, PFNA, GenX and PFBS, where above 1 is over the limit) Rounds to the limit Limit 1 | 1.38 |
| PFBS Detected, below limit Guideline 2,000 ppt | 9.9 ppt |
| PFBA Detected, below limit Guideline 6,000 ppt | 10.1 ppt |
| PFHxA Detected, below limit Guideline 3,000 ppt | 10.1 ppt |
| PFPeA Detected, no limit | 12.3 ppt |
| PFHpA Detected, no limit | 5.45 ppt |
Why "rounds to the limit"? the Hazard Index (1.38) is slightly above the number on paper, but EPA compares results after rounding to the limit's precision (4.4 ppt rounds to 4), so it meets the limit as EPA applies it. Close enough to the limit to be worth watching.
For context: the PFOA average is higher than at 96% of the Florida systems EPA tested and the PFOS average is higher than at 97% of the Florida systems EPA tested.
29 PFAS tested, 9 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.
Lithium
Not detected in 2 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 1 ppb lead (Jul 2025 – Dec 2025). Below action level
Highest since 2016: 11.3 ppb (Dec 2021).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jul 2025 – Dec 2025 | 1 ppb |
| Jan 2025 – Jun 2025 | 1.2 ppb |
| Jul 2024 – Dec 2024 | 1 ppb |

Copper 90th percentile: 1.91 ppm (Dec 2021), action level 1,300 ppb.
Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.
Violations
Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

Questions
Is Lantana Water Treatment Plant water safe to drink?
Lantana Water Treatment Plant has no health-based violations since 2016. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.
Does Lantana Water Treatment Plant water have PFAS?
Yes. EPA's 2023–2025 testing of Lantana Water Treatment Plant found 9 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 11.3 ppt, PFOS 33.3 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Lantana Water Treatment Plant water?
The most recent 90th-percentile lead result for Lantana Water Treatment Plant is 1 ppb, for the period ending Dec 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
