Three North Dakota systems and 2025 reports
These existing public system profiles were reviewed August 3, 2026. Their 2025 report material retains the original review date and the sample periods printed in each source.
Fargo · ND0900336
The Red River and alternative sources
Fargo’s 2025 report identifies the Red River as its primary source, with alternatives that include the Sheyenne River and water stored in Lake Ashtabula. The report describes how those supplies support drought planning. It does not establish the intake or blend reaching a home today.
Bismarck · ND0800080
A collector well connected to the Missouri River
Bismarck’s 2025 report describes a horizontal collector well beside the Missouri River, drawing from an aquifer recharged by the river. A direct river intake is described as backup. The source arrangement is more specific than a general groundwater label.
Grand Forks · ND1800410
Two rivers, with independent or blended pumping
The reviewed Grand Forks report describes surface water from the Red River and Red Lake River, which the plant can pump independently or blend. This is dated report context. It does not establish current pumping or an address-level source.

Sources, methodology, and limitations
See how records are sourced, reviewed, dated, and limited before using a summary.
Review methodologyStatewide context
Separate source-water maps from customer records
System identity
A shared river does not make two systems interchangeable
Fargo is ND0900336, Bismarck is ND0800080, and Grand Forks is ND1800410. Fargo and Grand Forks both describe Red River water, but they have separate facilities, reports, and regulatory identities. Match the full PWSID before comparing results.
Source protection
Protection areas are not service boundaries
NDDEQ’s source-water resources explain assessments and protection planning; its Data and Maps directory links wellhead and source-point protection areas. Those mapped areas concern water sources. They do not identify which utility supplies an address or show a household test result.
Study periods
State studies and annual reports cover different periods
NDDEQ lists statewide PFAS studies for 2018, 2020, 2021, and 2023, plus a separate 2022 Red River summary. These are dated study documents with different coverage. They should not be treated as a single current statewide status table or substituted for a supplier’s report.
Official lookup
Start with the supplier name and full PWSID
Identity cross-check
Use Fargo as an exact-ID example
EPA’s public identity record matches FARGO CITY OF to ND0900336. Compare that exact identifier with the supplier named on your bill and report. NDDEQ’s Drinking Water Program is the state contact for regulatory records and questions.
The source-protection map serves a different purpose from a customer-service lookup. If the supplier or record is unclear, ask the provider or state program before choosing a report.
- Confirm the supplier on your bill, lease, or provider account.
- Keep the system name and full PWSID together when requesting records.
- Check the reporting period and any record-specific notes before comparing results.
Annual reports
Use the utility’s archive and the dates inside the report
Fargo and Bismarck provide official report collections. The existing Grand Forks overview retains its reviewed report link and source context. A 2025 report can include a table covering several years; check the date attached to each result.
If you cannot open the report or need another format or language, ask the utility for the correct system’s report and an accessible copy.

Official guidance
Find the right next step for your water source
Current instructions
Check the supplier’s current notice
NDDEQ’s public-notice-rule page provides notification guidance for water systems. The department’s general public-notice directory also covers environmental actions; it is not a comprehensive list of drinking-water advisories. Use the provider’s current message, affected area, dates, and instructions. Ask the provider how to receive future alerts.
Service-line materials
Ask for the inventory record for your connection
NDDEQ’s lead-and-copper resources include service-line inventory guidance and a consumer FAQ. Ask the utility what it has recorded for your connection, which ownership portions were identified, and how to resolve unknown information. Pipe-material records and tap-water samples answer different questions.
Private-well sampling
Plan the test before collecting the sample
NDDEQ’s private-well testing guide, updated April 2026, says analysis suites vary by laboratory. Ask about your testing question, available analyses, sample containers, preservation, and how soon the sample must reach the laboratory. The department can help locate a laboratory.
The guide distinguishes water collected before household treatment from water collected after treatment. Tell the laboratory which question you are trying to answer and follow its collection instructions.
PFAS studies
Read the study year and sample coverage
NDDEQ’s PFAS page separates statewide studies from its Red River summary and links further guidance. Check which water sources and sampling periods a study includes before comparing it with a utility report or private-well test. A study title alone does not establish a result for your home.
Laboratory reports
Keep qualifiers and detection limits with the result
NDDEQ’s February 2024 PFAS laboratory guide explains the result, units, qualifiers, reporting limit, and method detection limit as separate fields. “ND” means non-detect in that laboratory context; it does not mean a measured concentration of zero. The guide’s illustrated sample report is an example, not a result for a named North Dakota water system.
Common questions
Reading North Dakota water information
Source descriptions
Why does Bismarck’s report mention both a well and a river?
The cited report describes a collector well in an aquifer recharged by the Missouri River and a direct river intake used as backup. Those details describe the utility’s source arrangement. They do not describe an individually owned household well.
Regional sources
Can I use Fargo’s report for Grand Forks?
No. Sharing a river name does not make the systems or their monitoring interchangeable. Use Fargo ND0900336 or Grand Forks ND1800410 only after confirming the supplier that serves you.
Laboratory notation
Does “ND” always stand for North Dakota?
Not in a laboratory result column. The NDDEQ PFAS guide uses ND for non-detect. Read the table legend and retain its detection limit and qualifiers. In a full PWSID such as ND0900336, ND is part of the system identifier.
