Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 4 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 537 violations on record, including 28 health-based violations. 81 remain unresolved.
What to know about Winter Haven's water
Winter Haven ranks #363 out of 388 cities in Florida for water quality, placing it among the lowest-rated in the state.
Winter Haven relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Haloacetic acid (HAA5) levels were elevated at 33.4 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.
Hexavalent chromium (chromium-6) was detected at 0.06 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
The system has seen 213 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Is Winter Haven, FL tap water safe to drink?
Winter Haven's water quality earned a grade of F (38.7/100). Significant issues have been found. A water filter is strongly recommended. The city ranks #363 out of 388 cities tested in Florida.
What contaminants are in Winter Haven's water?
Lead was measured at 0.0 ppb (90th percentile). 4 PFAS compounds were detected. 537 violations are on record.
How is Winter Haven's water quality grade calculated?
The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.
Do I need a water filter in Winter Haven?
PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.
Where does Winter Haven's water come from?
Winter Haven's water is sourced from Groundwater. The city has 19 water systems serving approximately 114,743 residents.
What health violations has Winter Haven's water system had?
Winter Haven has 28 health-based violations on record. The most recent violation was recorded in December 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 81 violations remain unresolved.
Is Winter Haven's groundwater at risk of contamination?
Winter Haven uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity.
