PFAS in Drinking Water in North Dakota
What residents of North Dakota need to know about PFAS ("forever chemicals") in drinking water — including contamination sources, which utilities have documented violations, and how to filter PFAS from tap water.

Quick Answer
Is PFAS in drinking water a real concern in North Dakota?
PFAS contamination in North Dakota is primarily linked to Minot AFB in Ward County and Grand Forks AFB in Grand Forks County — two major Air Force bases with extensive AFFF use histories. Both bases have documented PFAS contamination in surrounding groundwater. North Dakota's largely agricultural population means many residents rely on private wells that are unregulated for PFAS.
Where does PFAS come from in North Dakota?
Minot AFB (B-52 bomber base) and Grand Forks AFB are North Dakota's primary military PFAS sources. AFFF from flight operations and fire training has contaminated groundwater in Ward County (Minot area) and Grand Forks County. North Dakota's flat terrain and shallow water tables can allow rapid PFAS migration from contamination sources into nearby wells.
What should North Dakota residents know?
Ward County residents near Minot AFB and Grand Forks County residents near Grand Forks AFB face the most direct risk. North Dakota NDDEQ has conducted PFAS testing under UCMR5. Rural North Dakota private well users near these bases have no regulatory protection and should test independently.
Key Facts
| EPA MCL (PFOA/PFOS) | 4 ppt — effective April 2024 |
| MCLG | Zero |
| Primary contamination sources | Minot AFB (Ward County), Grand Forks AFB (Grand Forks County) — AFFF-related |
| State regulator | North Dakota Department of Environmental Quality (NDDEQ) |
| Private well concern | North Dakota's agricultural private well users near military/industrial sources — no regulatory PFAS protection |
| Health effects | Cancer (kidney, testicular), thyroid disruption, immune effects, developmental toxicity |
| Effective treatment | Reverse osmosis (NSF/ANSI 58) or granular activated carbon |
Why PFAS Matters in North Dakota
North Dakota's two major Air Force bases represent significant AFFF contamination sources in a largely rural state. Minot AFB — home of B-52 bombers and Minuteman III intercontinental ballistic missiles — has had extensive AFFF use for aircraft fire suppression. Grand Forks AFB, with its own history of AFFF use, has generated documented PFAS plumes in the Red River Valley area. The relatively small populations near these bases and the state's rural character mean fewer residents are directly affected, but those who are — particularly private well users — have limited access to alternative water sources.
North Dakota PFAS Regulation
North Dakota DEQ participates in UCMR5 monitoring. Minot AFB and Grand Forks AFB are the primary military PFAS assessment sites, with AFFF contamination documented at both bases. North Dakota's largely rural character and reliance on Missouri River and groundwater sources means most residents receive water from small systems with limited PFAS monitoring history. North Dakota follows the federal MCL with no additional state standard.

What Are PFAS (“Forever Chemicals”)?
PFAS are a family of over 12,000 synthetic chemicals used in non-stick cookware, stain-resistant fabrics, food packaging, and AFFF firefighting foam. Their carbon-fluorine bonds do not break down in the environment or the body — hence the name “forever chemicals.” AFFF used at military bases is the single largest source of PFAS in U.S. drinking water.

Minot and rural Ward County residents near Minot AFB, and Grand Forks area residents near Grand Forks AFB, face the highest documented risk. North Dakota's extensive private well population across agricultural regions should consider testing, especially if near any industrial or fire training facility.

Pregnant residents and families with young children
Residents in communities with documented PFAS detections
Anyone who has consumed water above 4 ppt for an extended period
Residents near airports, fire training areas, or industrial manufacturers
How to Check Your Situation in North Dakota
- 1
Identify your water utility using the ZIP lookup below or by browsing the North Dakota utility directory on this site.
- 2
Review your utility's Consumer Confidence Report (CCR) — it must report PFAS monitoring results under UCMR5 and the new MCL.
- 3
Check the EPA's ECHO database for your utility's monitoring history. Look for PFAS, PFOA, PFOS, and related compound results.
- 4
Contact your utility directly and ask for their most recent PFAS test results and whether they are implementing treatment under the 2024 MCL.
- 5
If you use a private well near a military base, airport, or industrial facility, order a PFAS panel test from a state-certified laboratory. Tests typically cost $150–$400.
- 6
If PFAS is detected above 4 ppt in your source water, install a certified NSF/ANSI 58 reverse osmosis system or an NSF/ANSI 53-certified activated carbon filter rated for PFAS removal.
How to Remove PFAS from Tap Water
Reverse Osmosis (Best)
90–99% removal — NSF/ANSI 58 certified systems only
Certified Activated Carbon
Effective with NSF/ANSI 53 or 58 certification — verify before buying
Boiling concentrates PFAS. Standard pitcher filters and water softeners do not remove PFAS. Always verify NSF certification before purchasing.
Take Action Now
Look up your North Dakota utility's PFAS monitoring history on the PFAS Watchlist below.
If your utility has detected PFAS above 4 ppt, install an NSF/ANSI 58-certified reverse osmosis system at your drinking tap.
Private well owners near military or industrial sites should order a PFAS panel test ($150–$400 at a state-certified lab).
Request your utility's most recent Consumer Confidence Report — PFAS results must be disclosed under the new 2024 MCL.
