Well water testing in North Carolina

Where to get it tested
Three routes, and all of them work. A mail-in kit from a certified lab is the simplest: the lab ships bottles, you fill them at the kitchen tap, and results come back by email. The full panel above is $209.
A local certified lab is the second route. NCSLPH - Lab Certification from NCDHHS lists every lab certified for drinking water in North Carolina. Call ahead: some take walk-in samples, some ship bottles.

Common questions
What should I test my well for in North Carolina?
Start with nitrate, uranium, arsenic. 11% of 6,130 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 Carolina?
Use a lab certified for drinking water. NCDHHS keeps the list of certified labs. A mail-in kit from a certified lab works anywhere in the state.
How much does well water testing cost in North Carolina?
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).
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.
