01The verdict: is Washburn water safe?
Washburn's tap water meets most EPA standards but has areas that warrant attention. With a grade of A (90/100), some contaminant levels or compliance issues suggest that residents may benefit from additional filtration. The city's 1 water system serves approximately 1,246 residents using surface water (rivers, lakes, or reservoirs).
1 unresolved violation on record
EPA records show an open compliance item for this system. Most are administrative, but unresolved items are worth watching.

See the risk factors ↓Washburn's drinking water received a grade of A (90 out of 100), indicating excellent water quality. The city's 1 water system serves approximately 1,246 residents using surface water.
Lead levels were measured at 5.1 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 30 violations on record, including 23 health-based violations. 1 remains unresolved.
Washburn ranks #34 out of 101 cities in North Dakota for water quality, placing it mid-range in the state. The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Washburn may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

05Pressure on Washburn's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Industrial discharge
2 facilities within 10 miles reported 0 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.

Filter drinking & cooking water
Basic carbon filter for extra protection. Lead detected at 5.1 ppb
Compare tested filters →Flush taps & check your service line
Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.
