Summary
No federal limits exceeded in EPA data.
- PFAS
- Not detectedNone of 29 PFAS found above EPA's reporting limits in 6 samples (2023–2025).
- Lead
- Below action level0.4 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.
- 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.

- Read Toho Water Authority – Poinciana System'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 (407) 944-5131. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 3 entry points tested Jun 2024 to Dec 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 Not detected Limit 4 ppt | – |
| PFOS Not detected Limit 4 ppt | – |
| PFHxS Not detected Limit 10 ppt | – |
| PFNA Not detected Limit 10 ppt | – |
| 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) Not detected Limit 1 | – |
| PFBS Not detected Guideline 2,000 ppt | – |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
29 PFAS tested, 0 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 6 samples (reporting limit 9 ppb). About lithium.
Lead and copper
Latest 90th percentile: 0.4 ppb lead (Jul 2025 – Dec 2025). Below action level
Highest since 2016: 0.9 ppb (Dec 2019).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jul 2025 – Dec 2025 | 0.4 ppb |
| Jan 2025 – Jun 2025 | 0.6 ppb |
| Jan 2023 – Dec 2023 | 0.4 ppb |
Earlier results (9)
| Jan 2020 – Dec 2020 | 0.4 ppb |
| Jul 2019 – Dec 2019 | 0.9 ppb |
| Jan 2019 – Jun 2019 | 0 ppb |
| Jan 2017 – Dec 2017 | 0.5 ppb |
| Jan 2014 – Dec 2014 | 0 ppb |
| Jan 2013 – Dec 2013 | 1.3 ppb |
| Jul 2010 – Dec 2010 | 0.8 ppb |
| Jan 2010 – Jun 2010 | 1 ppb |
| Jan 2009 – Dec 2009 | 1.3 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.
Earlier EPA testing (2013–2020)
| Contaminant | Highest | Guideline |
|---|---|---|
| Manganese | 1.7 ppb | 300 ppb |
| Chlorate | 1,120 ppb | 210 ppb |
| Molybdenum | 27.9 ppb | 40 ppb |
| Vanadium | 6.8 ppb | 21 ppb |
| Chromium-6 | 0.035 ppb | – |
| Strontium | 0.34 ppm | 1.5 ppm |
