01The verdict: is Beulah water safe?

Beulah's tap water meets most EPA standards but has areas that warrant attention. With a grade of A (95/100), some contaminant levels or compliance issues suggest that residents may benefit from additional filtration. The city's 1 water system serves approximately 3,058 residents using groundwater (wells).

The concern

1 unresolved violation on record

EPA records show an open compliance item for this system. Most are administrative, but unresolved items are worth watching.

The good news

Lead is well under the limit

90th-percentile lead is 0.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

Keep watching

lithium is approaching its limit

Measured at 27.9000 µg/L — 120% of the 0.004 µg/L limit. Within the rules, but with less headroom than you'd want.

See the ledger ↓

Beulah's drinking water received a grade of A (95 out of 100), indicating excellent water quality. The city's 1 water system serves approximately 3,058 residents using groundwater.

Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 1 PFAS compound in the water supply. The system has 5 violations on record, including 3 health-based violations. 1 remains unresolved.

Beulah ranks #4 out of 101 cities in North Dakota for water quality, placing it one of the best in the state. Beulah relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter. Hexavalent chromium (chromium-6) was detected at 0.43 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration. As a small community water system, Beulah may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

04Where Beulah's water comes from

Beulah's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

1 system

1 water system, operated under local government ownership.

Delivery

3,058 people

Residents served across Beulah's service area.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by local government ownership and serves approximately 3,058 people through 1 water system.
