Comprehensive analysis of Kentucky water quality across 3 cities • Based on real EWG testing data • Updated 2026
If you live in Kentucky, you may be showering in water that contains contaminants exceeding health guidelines — and you might not even know it. Our analysis of water quality data across 3 Kentucky cities reveals 8 contaminants that may exceed EWG health guidelines.
Kentucky faces unique water quality challenges including coal mining runoff and aging infrastructure. Whether you're in Frankfort or elsewhere in the state, understanding what's in your shower water is the first step toward protecting your skin and hair.
📊 Kentucky Water Quality at a Glance
Across Kentucky, we analyzed water quality data from the Environmental Working Group (EWG) database. The results show that Kentucky residents may be exposed to a range of contaminants through their shower water — many at levels that exceed health guidelines set by the EWG, which are often stricter than federal legal limits.
⚠️ Top Contaminants Found in Kentucky Water
Based on EWG data analysis, here are the most significant contaminants detected in Kentucky water supplies:
| Contaminant | Avg. Level | EWG Guideline | Status |
|---|---|---|---|
| Perfluorohexane sulfonate (PFHXS) | 0.0000 ppt | 0.0000 ppt | ⚠️ 948.0x above |
| Haloacetic acids (HAA9) | 33.84 ppb | 0.0600 ppb | ⚠️ 564.0x above |
| Haloacetic acids (HAA5) | 27.29 ppb | 0.1000 ppb | ⚠️ 272.9x above |
| Total trihalomethanes (TTHMs) | 38.83 ppb | 0.1500 ppb | ⚠️ 258.9x above |
| Arsenic | 0.4778 ppb | 0.0040 ppb | ⚠️ 119.4x above |
| Radium, combined (-226 and -228) | 1.3750 pCi/L | 0.0500 pCi/L | ⚠️ 27.5x above |
| Perfluorooctanoic acid (PFOA) | 0.0000 ppt | 0.0000 ppt | ⚠️ 14.9x above |
| Chromium (hexavalent) | 0.2017 ppb | 0.0200 ppb | ⚠️ 10.1x above |
Perfluorohexane sulfonate (PFHXS)
The health guideline of 0.001 ppt for perfluorohexane sulfonate was defined by EWG based on studies by Phillipe Grandjean of Harvard University and many other independent researchers who found reduced effectiveness of vaccines and adverse impacts on mammary gland development from exposure to PFOA and PFOS, the two PFAS most widely detected in drinking water. This health guideline harm to the developing immune system.
National Average: 0.0000 ppt | Kentucky Average: 0.0000 ppt
Haloacetic acids (HAA9)
The health guideline of 0.06 ppb for haloacetic acids (HAA9) was defined by EWG . This health guideline protects against cancer.
National Average: 23.70 ppb | Kentucky Average: 33.84 ppb
Haloacetic acids (HAA5)
The health guideline of 0.1 ppb for haloacetic acids (HAA5) was established. This health guideline protects against cancer.
National Average: 19.82 ppb | Kentucky Average: 27.29 ppb
Total trihalomethanes (TTHMs)
The health guideline of 0.15 ppb for trihalomethanes was defined by in a peer-reviewed scientific study by EWG and represents a one-in-one-million lifetime cancer risk level. as a draft public health goal, the level of drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.
National Average: 29.06 ppb | Kentucky Average: 38.83 ppb

🩺 Health Effects of Kentucky Water Contaminants
The contaminants found in Kentucky water may be associated with various health concerns. When you shower, your skin — your body's largest organ — can absorb these substances, and you may inhale steam containing volatile compounds.
🧴 Skin & Hair
🫁 Respiratory
- Steam inhalation of chlorine/VOCs
- May aggravate asthma symptoms
- Potential respiratory irritation
⚕️ Long-Term Concerns
- Disinfection byproduct exposure
- Eczema flare-ups
- Cumulative contaminant absorption
🛡️ How to Protect Yourself from Kentucky Water Contaminants
The good news: you don't have to accept whatever comes out of your Kentucky showerhead. A quality shower filter can significantly reduce many of the contaminants found in your water.
Key contaminants a shower filter can help address:
- Haloacetic acids (HAA9) — learn about health effects and removal
- Total trihalomethanes (TTHMs) — learn about health effects and removal
- Arsenic — learn about health effects and removal
- Chromium (hexavalent) — learn about health effects and removal
Additionally, understanding common symptoms can help you identify water quality issues:
