North Dakota's drinking water sources split between:
- The Missouri River system: Delivered via the Garrison Diversion Unit and the Northwest Area Water Supply project, which brings treated Missouri River water to Bakken-region communities that would otherwise rely on strained local supplies.
- Groundwater: Widespread across the state, much of it mineral-heavy — hardness, sulfate, and iron/manganese are common, requiring softening and treatment beyond simple disinfection.
