Forever Chemicals
If your family is relocating to North Dakota, getting your bearings on the water is a sensible early step. The state's Department of Environmental Quality, through its Division of Municipal Facilities, oversees public drinking water across a state where many people live well outside the bigger systems. PFAS, the forever chemicals, are the kind of topic that makes a new arrival pause. The figures below come from monitoring of North Dakota's public water systems, and what the records show is worth reviewing when evaluating an address. Read it as orientation rather than a conclusion, because no statewide dataset speaks to one specific tap.
EPA's UCMR 5 program (2021–2024) tested 38 public water systems in North Dakota for 29 PFAS compounds; 5 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 13% detection rate). Detections vary by water system — check the utility serving a specific North Dakota address.
In North Dakota, drinking-water oversight runs through the Department of Environmental Quality (DEQ) and its Division of Municipal Facilities, which administers public-water-system standards across a largely rural state. North Dakota is among the states that rely on the federal limits the agency administers rather than setting its own enforceable PFAS drinking-water number ahead of the April 2024 rule. The DEQ tends to follow that federal framework while monitoring public systems, so the figures below largely reflect testing carried out under the national program rather than a stricter state standard.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in North Dakotaserving 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 North Dakotautilities 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 |
|---|---|---|---|
| GRAND FORKS REGIONAL WTP | 1 | 0.01 | Below MCL |
| CENTRAL PLAINS WATER DISTRICT | 1 | 0.01 | Below MCL |
| NORTHWEST RURAL WATER DISTRICT, ND | 1 | 0.01 | Below MCL |
| SOUTH CENTRAL REGIONAL WATER DISTRICT | 1 | 0.01 | Below MCL |
| NORTH PRAIRIE RWD-SYSTEM 1&2 | 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 North Dakota 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 North Dakota installations, the address report will tell you exactly how close.

Looking at a specific North Dakotacity? 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.
North Dakota's military presence makes the water question concrete for many families. For decades, the firefighting foam known as AFFF was used in training, and it carries PFAS compounds that stay in soil and groundwater long after the training ends. For veterans and the families who lived alongside them, that can mean the water around a base you served at or called home. The installations listed above are flagged because of that documented link between foam use and groundwater PFAS. The link is why these sites get attention; it does not by itself describe what is in a particular home's water now, so a closer, address-level look is the reasonable next move.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 38 public water systems in North Dakota; 5 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
North Dakota is among the states that rely on the federal limits the Department of Environmental Quality administers rather than its own enforceable PFAS drinking-water number. Those federal limits, set in April 2024, are 4 ppt for PFOA and PFOS and 10 ppt for PFHxS, PFNA, and GenX.
The Department of Environmental Quality, through its Division of Municipal Facilities, oversees public water systems and tends to follow the federal PFAS framework. The posture is largely federal-default, meaning residents are covered by the national limits the DEQ administers rather than a stricter state-specific standard.
The Department of Environmental Quality is North Dakota's environmental agency, with public drinking-water oversight handled through its Division of Municipal Facilities. If you searched for the state's DEQ to understand local water quality, this is the office responsible.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any North Dakota 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.
