01The verdict: is Elizabethtown water safe?
Elizabethtown's drinking water has significant quality concerns based on EPA testing data. With a grade of B+ (81.2/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 1 water system serves approximately 76,326 residents using surface water (rivers, lakes, or reservoirs).
PFOA is over its legal limit
Measured at 0.0062 µg/L against the EPA MCL of 0.004 µg/L. The ledger below shows how far over — and which filter removes it.

See the ledger ↓Elizabethtown's drinking water received a grade of B+ (81.2 out of 100), indicating good water quality. The city's 1 water system serves approximately 76,326 residents using surface water.
Lead levels were measured at 6.0 ppb (90th percentile), which is within EPA limits but above recommended levels. UCMR 5 testing detected 7 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply. The system has 8 violations on record, including 3 health-based violations. 4 remain unresolved.
Elizabethtown ranks #142 out of 246 cities in Kentucky for water quality, placing it below average 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. Hexavalent chromium (chromium-6) was detected at 0.39 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.
02What's in Elizabethtown's water
Every contaminant flagged in Elizabethtown, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Over MCL — EPA MCL: 0.004 µg/L
PFAS "forever chemicals" exceed the 2024 EPA maximum contaminant levels, which utilities must meet by 2029. These compounds don't break down in the body or the environment. Reverse osmosis (NSF/ANSI 58) or certified granular activated carbon (NSF/ANSI 53) removes them at the tap.Full contaminants report

As a surface-water system, these water bodies may directly influence Elizabethtown's drinking water supply.
05Pressure on Elizabethtown's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
5 facilities within 10 miles reported 750 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
5 federal disaster declarations on record for Hardin County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.

What contaminants are in Elizabethtown's water?
Lead was measured at 6.0 ppb (90th percentile). 7 PFAS compounds were detected. 8 violations are on record.
How is Elizabethtown'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 Elizabethtown?
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 Elizabethtown's water come from?
Elizabethtown's water is sourced from Surface water. The city has 1 water system serving approximately 76,326 residents.
What health violations has Elizabethtown's water system had?
Elizabethtown has 3 health-based violations on record. The most recent violation was recorded in July 2021. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 4 violations remain unresolved.
Why does Elizabethtown have so many PFAS compounds in its water?
7 different PFAS "forever chemical" compounds were detected in Elizabethtown'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.
