Lead In Drinking Water In North Dakota
What residents of North Dakota need to know about lead in drinking water — including how it enters water, which utilities have documented violations, and what steps to take.

Quick Answer
Is lead in drinking water a real concern in North Dakota?
Yes — Fargo, Bismarck, Grand Forks, and Minot have older neighborhoods with pre-1986 housing where lead solder and service connections may be present.
Is this mostly a public-water issue, a private-well issue, or both?
Primarily household plumbing and service connections in older North Dakota city neighborhoods; the state's colder climate means water sits in pipes for longer periods in winter, increasing contact time with lead materials.
What is the main reason residents should care?
North Dakota's older city cores have concentrations of pre-1940 housing with lead solder and older service connections. The state's cold winters mean indoor plumbing may go unused for extended periods — increasing the duration of water-lead contact before the first morning draw.
Key Facts
| Federal Lead Action Level | 15 µg/L — no safe level per CDC |
| Cold climate factor | Long periods of non-use in cold weather increase contact time between water and lead plumbing |
| City risk areas | Older Fargo, Bismarck, Grand Forks neighborhoods — pre-1940 housing stock |
| Federal MCLG | Zero |
| State oversight | North Dakota Department of Environmental Quality (NDDEQ) |
Why This Matters in North Dakota
Fargo, Bismarck, Grand Forks, and Minot all have older city cores with pre-1940 housing built during the agricultural and railroad development era of the Northern Plains. Lead service lines and lead solder were standard construction practices during this period. North Dakota's extreme cold winters mean that household pipes can go without flow for extended periods (overnight, through weekends), increasing the contact time between standing water and any lead-bearing plumbing materials. This is particularly relevant for first-draw water in the morning or after a weekend away. NDDEQ enforces the Lead and Copper Rule and requires utilities to complete service line inventories.
North Dakota Utilities With Lead Violation Records
The utilities listed below have at least one lead violation on record in EPA's SDWIS database. Violations may be open or resolved — see individual utility pages for current status and risk level.
How Lead Gets Into Drinking Water
Lead service lines
The pipe connecting a home to the water main may be made of lead, especially in pre-1986 construction. Water sitting in these lines can accumulate lead before it reaches the tap.
Lead solder
Lead solder at pipe joints was banned for potable water systems in 1986. Homes built before that date — including significant portions of older North Dakota cities — may still have lead solder throughout their plumbing.
Older brass fixtures
Faucets, valves, and fixtures with high lead content were common before the 2014 revision of 'lead-free' standards. Replacing older fixtures at kitchen and drinking taps can meaningfully reduce exposure.
Corrosive water chemistry
Soft, acidic, or low-alkalinity water dissolves lead from plumbing more readily. Utilities use orthophosphate and other corrosion control treatments, but household plumbing after the meter is not within their control.
Who Should Pay Closest Attention
Families with young children in older Fargo, Bismarck, and Grand Forks neighborhoods should flush cold taps for 30 seconds to 2 minutes before using water after any period of non-use, and consider a certified NSF/ANSI 53 or 58 filter for drinking and cooking water.
Families with children under six
Pregnant residents
Households in homes built before 1986
Renters who cannot inspect building plumbing
Residents on a confirmed lead service line
Households that had plumbing work done recently (disturbances dislodge protective scale)
How to Check Your Situation in North Dakota
- 1
Identify your water utility. Use the ZIP lookup below or browse the North Dakota utility directory on this site.
- 2
Read your utility's page on this site to see its current risk level and any open lead violations.
- 3
Contact your utility and ask for your address-level service line material status. Under the federal Lead and Copper Rule Revisions (LCRR), utilities must maintain and provide this information.
- 4
Review your utility's most recent Consumer Confidence Report (CCR) — mailed annually or available on the utility's website.
- 5
Consider testing your tap water at a North Dakota Department of Environmental Quality (NDDEQ)-certified lab. Your state health department or North Dakota Department of Environmental Quality (NDDEQ) maintains a list of certified labs.
- 6
If you have young children or are pregnant, install a certified NSF/ANSI 53 or 58 filter at the kitchen tap as a precautionary measure.
Treatment Options
Boiling does not remove lead. Use a certified filter for drinking and cooking water.
NSF/ANSI Standard 53 — Activated Carbon Block
Under-sink or pitcher filters certified to Standard 53 are independently verified to reduce lead. Replace filters on the manufacturer's schedule — an overdue filter may not perform as certified.
NSF/ANSI Standard 58 — Reverse Osmosis
RO systems certified to Standard 58 remove 95–99% of lead and a broad range of contaminants. Requires under-sink installation. More comprehensive than Standard 53 for households with multiple contaminant concerns.
Flushing — temporary mitigation only
EPA recommends flushing the cold tap for 30 seconds to 2 minutes if water has sat in pipes for 6+ hours. Not a substitute for certified filtration or service line replacement.
