waterverge.com Lebanon, TN — Water Quality Report
Lebanon's drinking water received a grade of C- (60 out of 100), indicating fair water quality. The city's 6 water systems serve approximately 120,697 residents using surface water.
Lead levels were measured at 7.5 ppb (90th percentile), which is within EPA limits but above recommended levels. UCMR 5 testing detected 5 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 62 violations on record, including 21 health-based violations. 12 remain unresolved.
What to know about Lebanon's water
Lebanon ranks #276 out of 299 cities in Tennessee for water quality, placing it among the lowest-rated in the state.
The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.
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 30.4 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 0.14 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.
While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.
The system has seen 10 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

What Lebanon residents can do
Recommended: Reverse osmosis system. This addresses the specific contaminants found in Lebanon's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.

Do I need a water filter in Lebanon?
While lead levels are within EPA limits, a filter adds extra protection. PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.
Where does Lebanon's water come from?
Lebanon's water is sourced from Surface water. The city has 6 water systems serving approximately 120,697 residents.
What health violations has Lebanon's water system had?
Lebanon has 21 health-based violations on record. The most recent violation was recorded in July 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 12 violations remain unresolved.
Why does Lebanon have so many PFAS compounds in its water?
5 different PFAS "forever chemical" compounds were detected in Lebanon'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 Lebanon's water compare to other cities?
Lebanon ranks #276 out of 299 cities in Tennessee (better than 8% of state cities) and #12117 out of 15744 cities nationally (23th percentile). The grade of C- reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
