Common questions
What should I test my well for in North Dakota?
Start with arsenic, uranium, lead. 29% of 2,341 local samples were above the limit. Add total coliform bacteria and nitrate every year for any private well.
Where can I get my well water tested in North Dakota?

How much does well water testing cost in North Dakota?
A full mail-in panel from a certified lab costs $209 (Tap Score well water test kit). A bacteria-only test costs $99 (Tap Score coliform and E. coli test). The North Dakota state public health laboratory mails private well owners a collection kit for a bacterial (satisfactory or unsatisfactory) test, and the page lists a payment of $27.00 per sample.
How often should a private well be tested?
Bacteria and nitrate every year. A full panel once, then again after flooding, a change in taste, smell or color, work on the well, a new baby in the house, or a nearby result above the limit. Contaminants that come from the rock, like arsenic, radon and uranium, change slowly, so one good test and a check every few years is enough.
