Maybe you're researching your own long-term health, the kind of question that doesn't go away once you've thought it. Maybe you've just lived in Kentucky long enough to wonder what the testing actually says. Either way, the data below is federal; the orientation is local. Kentucky's drinking water falls to the Energy and Environment Cabinet (EEC) and its Division of Water, the office that runs the public water supply program statewide. Nothing here is a ruling on a specific home. It's the statewide record, laid out so the figures in the cards become something you can read calmly and review when evaluating an address.
EPA's UCMR 5 program (2021–2024) tested 49 public water systems in Kentucky for 29 PFAS compounds; 4 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 8% detection rate). Detections vary by water system — check the utility serving a specific Kentucky address.
In Kentucky, drinking water sits under the Kentucky Energy and Environment Cabinet (EEC), and more specifically its Division of Water, which administers the state's public water supply rules. Kentucky tends to be among the states that rely on the federal framework rather than legislating its own PFAS number: the Division of Water largely administers the limits set by the April 2024 federal rule, which fixes PFOA and PFOS at 4 parts per trillion. That makes the posture here federal-default, with the state agency as the office doing the enforcing. The reassuring part is simply that there is one, with a name and a phone number, standing behind the records below.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in Kentuckyserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

These are the Kentuckyutilities where EPA testing found PFAS the most often or at the highest levels. Being on this list doesn't automatically mean today's tap water is unsafe — some systems have added treatment since these samples were taken — but it means a conversation with the utility is worth having before you move in.
| Water system | Detections | Max value (ng/L) | vs 2024 MCL |
|---|---|---|---|
| CANNONSBURG WATER DISTRICT | 1 | 0.01 | Below MCL |
| S E DAVIESS CO WATER DISTRICT | 1 | 0.01 | Below MCL |
| LAWRENCEBURG WATER & SEWER DEPT | 1 | 0 | Below MCL |
| SO ANDERSON WATER DISTRICT | 1 | 0 | Below MCL |
PFAS isn't one chemical — it's a family of thousands. Here are the specific compounds EPA picked up most often across Kentucky water systems. PFOA and PFOS are the two with the strictest federal limits (4 parts per trillion).
Looking at a specific Kentuckycity? Each page below pulls the same federal data narrowed to that water system — useful whether you're relocating, buying, organizing your neighborhood around getting cleaner water, or just trying to find out what's in the tap and what's around you.
Start with the limits of the picture. The federal UCMR5 program tested for 29 PFAS compounds, but only in public water systems serving more than about 3,300 people, with sampling spread across 2021 to 2024. In a state with as many hollows and small communities as Kentucky, that leaves a lot uncovered: private wells and the tiniest rural systems weren't required to sample, so a blank spot on the map is genuinely unknown, not confirmed clean. The Division of Water offers guidance for well owners worth tracking down if you draw from your own ground. And a detection from a couple of years ago is a moment in time, not a live reading. The alphabet (UCMR, MCL) is dense; the question under it is plain.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 49 public water systems in Kentucky; 4 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
Kentucky is among the states whose residents are covered by the federal limits its agency administers, rather than separate state numbers. The Kentucky Energy and Environment Cabinet (EEC), through its Division of Water, largely enforces the April 2024 federal PFAS rule, which sets PFOA and PFOS at 4 parts per trillion plus levels for PFHxS, PFNA, and GenX. The protection comes from the national standard, applied locally.
PFAS in drinking water is handled by the Kentucky Division of Water, part of the Energy and Environment Cabinet (EEC). The agency tends to administer the federal PFAS standards rather than write its own, overseeing monitoring and compliance for community water systems under the 2024 rule. Private wells generally fall outside that program, so the Division of Water steers well owners toward separate testing guidance.
The Energy and Environment Cabinet (EEC) is Kentucky's umbrella state agency for environmental protection and energy policy. Its Division of Water administers the public water supply program, including PFAS monitoring under the federal rule. If you came looking for the office that oversees Kentucky's drinking water, the Division of Water within the EEC is the one to know.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any Kentucky address, alongside nearby military bases and industrial PFAS sources. The data comes from EPA UCMR 5, EPA TRI, and the DoD PFAS installation report.
In April 2024 the EPA set the first enforceable federal limits for PFAS in drinking water: 4 parts per trillion for PFOA and PFOS, and 10 ppt each for PFHxS, PFNA, and HFPO-DA (GenX), plus a Hazard Index for certain mixtures. Public water systems must complete initial monitoring by 2027 and come into compliance after that.
No. The federal limits apply to public water systems. Private well owners are responsible for their own testing and treatment, which is especially worth doing near a known PFAS source like a military base or industrial site.
State numbers tell you the pattern. An address report tells you what's actually in the water at yourkitchen sink — the matched utility, the PFAS detections on file, and every military or industrial source nearby. Whether it's for your family, your neighbors, or peace of mind.
