Clermont's drinking water received a grade of F (36.2 out of 100), indicating failing water quality. The city's 14 water systems serve approximately 107,187 residents using groundwater.
Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 6 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 281 violations on record, including 58 health-based violations. 56 remain unresolved.
What to know about Clermont's water
Clermont ranks #378 out of 388 cities in Florida for water quality, placing it among the lowest-rated in the state.
Clermont 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.
Hexavalent chromium (chromium-6) was detected at 0.40 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 52 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Clermont's water quality earned a grade of F (36.2/100). Significant issues have been found. A water filter is strongly recommended. The city ranks #378 out of 388 cities tested in Florida.
What contaminants are in Clermont's water?
Lead was measured at 0.0 ppb (90th percentile). 6 PFAS compounds were detected. 281 violations are on record.
How is Clermont'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 Clermont?
PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.
Where does Clermont's water come from?
Clermont's water is sourced from Groundwater. The city has 14 water systems serving approximately 107,187 residents.
What health violations has Clermont's water system had?
Clermont has 58 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. 56 violations remain unresolved.
Is Clermont's groundwater at risk of contamination?
Clermont uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 281 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.
Why does Clermont have so many PFAS compounds in its water?
6 different PFAS "forever chemical" compounds were detected in Clermont's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.
How does Clermont's water compare to other cities?
Clermont ranks #378 out of 388 cities in Florida (better than 3% of state cities) and #15475 out of 15744 cities nationally (2th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
