Official lab list for North Dakota
How to choose a lab
- Pick a lab on the official list above that is certified for each test you need (bacteria and chemistry are often separate certifications).
- Ask for the lab’s own sample bottles and instructions; bacteria samples usually must reach the lab within 24–30 hours.
- Compare prices for a basic package (bacteria, nitrate, pH/TDS) and add arsenic or other metals where local data shows a risk.
- Be wary of free in-home tests from treatment-system sellers — see our salesperson checklist.
