Chase Groves Water System water quality
Winter Park, FL · serves 4,052 people (1,279 connections) · Purchased groundwater · Private · EPA ID FL3594214
Data: U.S. EPA · How we read the data · How we check it
Buys water from City of Sanford. Treated water bought from another system can carry that system's contaminants.
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 4.4 ppt vs a limit of 4 ppt, PFOS 6.2 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
- Lead
- Below action level0 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 2023. Your home's pipes can make yours higher.
- Violations
- Resolved1 health-based violation since 2016, most recently Jul 2020.
- 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 Chase Groves Water 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) 665-2795. EPA: how to find it.
PFAS (“forever chemicals”)
EPA UCMR 5: 1 entry point tested Feb 2025 to Aug 2025. "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 | 4.4 ppt 1.1× the limit |
| PFOS Above limit Limit 4 ppt | 6.2 ppt 1.55× the limit |
| PFHxS Detected, below limit Limit 10 ppt | 3.5 ppt 35% of the limit |
| 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) Detected, below limit Limit 1 | 0.35 |
| PFBS Detected, below limit Guideline 2,000 ppt | 4.6 ppt |
| PFBA Not detected Guideline 6,000 ppt | – |
| PFHxA Not detected Guideline 3,000 ppt | – |
For context: the PFOA average is higher than at 83% of the Florida systems EPA tested and the PFOS average is higher than at 73% of the Florida systems EPA tested.
29 PFAS tested, 4 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: 0 ppb lead (Jan 2023 – Dec 2023). Below action level
Highest since 2016: 1.5 ppb (Dec 2020).
| Monitoring period | Lead (90th pct.) |
|---|---|
| Jan 2023 – Dec 2023 | 0 ppb |
| Jan 2020 – Dec 2020 | 1.5 ppb |
| Jan 2017 – Dec 2017 | 1.5 ppb |
Earlier results (9)
| Jan 2014 – Dec 2014 | 1.3 ppb |
| Jan 2011 – Dec 2011 | 2.1 ppb |
| Jan 2010 – Dec 2010 | 1 ppb |
| Jan 2007 – Dec 2007 | 2.1 ppb |
| Jan 2001 – Dec 2001 | 1.2 ppb |
| Jan 1998 – Dec 1998 | 1 ppb |
| Jan 1997 – Dec 1997 | 0 ppb |
| Jan 1996 – Dec 1996 | 0 ppb |
| Jul 1995 – Dec 1995 | 1.2 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
| When | What happened |
|---|---|
| Jul 2020 | The running annual average for TTHM was above the legal limit. EPA record: TTHM · Maximum Contaminant Level Violation, Average · measured 87.4 ug/l (limit 0.080 mg/L) Resolved |
1 unresolved monitoring or reporting violation: Consumer Confidence Rule.
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 Chase Groves Water System water safe to drink?
Chase Groves Water System had 1 health-based violation since 2016, all since resolved. 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 Chase Groves Water System water have PFAS?
Yes. EPA's 2023–2025 testing of Chase Groves Water System found 4 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 4.4 ppt, PFOS 6.2 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).
What is the lead level in Chase Groves Water System water?
The most recent 90th-percentile lead result for Chase Groves Water System is 0 ppb, for the period ending Dec 2023. 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.
