If you're settling into a new corner of Kansas, or just got curious about what's actually under the prairie you've always called home, this page is where the public record meets plain language. The figures below come from federal drinking-water testing; the framing comes from knowing who's responsible for it. In Kansas that's the Kansas Department of Health and Environment (KDHE), the agency that runs the state's public water supply program. None of this is a verdict on any single address. It's a statewide picture worth reviewing when evaluating an address, so the numbers in the cards stop feeling like noise and start telling you something.
EPA's UCMR 5 program (2021–2024) tested 43 public water systems in Kansas for 29 PFAS compounds; 7 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 16% detection rate). Detections vary by water system — check the utility serving a specific Kansas address.
In Kansas, the office watching the tap is the Kansas Department of Health and Environment (KDHE), whose Bureau of Water oversees the state's public water supply program. Kansas is among the states that lean on the federal framework rather than writing its own number: KDHE largely administers the limits set under the April 2024 federal PFAS rule, which caps PFOA and PFOS at 4 parts per trillion and sets levels for several related compounds. So the posture here is less 'Kansas drew a stricter line' and more 'KDHE enforces the national one.' That still means there is a named state office, not a faceless acronym, responsible for the water records you're reading below.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in Kansasserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

Red triangles are military installations the Department of Defense has flagged for PFAS from firefighting foam. Orange dots are industrial facilities that reported PFAS to the EPA Toxics Release Inventory. If your future home sits near a cluster, that's a conversation worth having with the seller or landlord.
These are the Kansasutilities 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 |
|---|---|---|---|
| FRUSI WATER TREATMENT PLANT | 6 | 0.02 | Below MCL |
| GREAT BEND, CITY OF | 2 | 0.01 | Below MCL |
| HAYS, CITY OF | 3 | 0.01 | Below MCL |
| OTTAWA, CITY OF | 1 | 0.01 | Below MCL |
| UNIVERSITY OF KANSAS | 1 | 0.01 | Below MCL |
| WATER DISTRICT 1 OF JOHNSON CO | 1 | 0.01 | Below MCL |
| DOUGLAS CO RWD 3 | 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 Kansas water systems. PFOA and PFOS are the two with the strictest federal limits (4 parts per trillion).
For decades the military trained with AFFF firefighting foam loaded with PFAS. It soaked into soil and groundwater and, in many places, traveled miles. If you're house-hunting near any of these Kansas installations, the address report will tell you exactly how close.

Looking at a specific Kansascity? 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.
Here's how to read what the records show. The federal UCMR5 testing program looked for 29 PFAS compounds in public water systems serving more than 3,300 people, sampled roughly between 2021 and 2024. That scope matters in a state with as much rural ground as Kansas: private wells and the smallest country systems weren't required to test at all, so a quiet map isn't the same as a clean one. KDHE does offer guidance for private well owners, which is worth a look if your water comes from your own ground. And remember a detection logged a couple of years back is a snapshot, not necessarily today's tap. The acronym soup (UCMR, MCL, and friends) is its own small ordeal, but the underlying question is simple: what was found, and where.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 43 public water systems in Kansas; 7 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
Kansas is among the states covered by the federal limits its agency administers rather than ones it wrote itself. The Kansas Department of Health and Environment (KDHE) largely enforces the April 2024 federal PFAS rule, which sets PFOA and PFOS at 4 parts per trillion and adds levels for PFHxS, PFNA, and GenX. So the protections residents rely on come from the national standard, applied through KDHE's public water supply program.
The Kansas Department of Health and Environment (KDHE), through its Bureau of Water, runs the state's public water supply program and tends to administer the federal PFAS standards rather than separate state numbers. In practice that means KDHE oversees monitoring and compliance for community water systems under the 2024 federal rule. Private wells generally fall outside that oversight, which is why KDHE points well owners toward its own testing guidance.
KDHE stands for the Kansas Department of Health and Environment, the state agency that handles both public health and environmental protection in Kansas. On the water side, its Bureau of Water administers the public water supply program, including PFAS monitoring under the federal rule. If you landed here looking for the office that oversees Kansas drinking water, KDHE is the one.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any Kansas 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.
