How mail-in testing works

How to get your water tested in North Carolina

  1. Pick a certified lab. In North Carolina, drinking water labs are certified by the North Carolina State Laboratory of Public Health.
  2. Choose your tests. For a private well, the EPA recommends testing every year for total coliform bacteria, nitrates, total dissolved solids and pH. Add local concerns like arsenic, lead or PFAS.
  3. Get the lab's bottles. Use the lab's sterile bottles and follow its instructions exactly. Bacteria samples usually have to reach the lab within about a day.
  4. Check the results against EPA limits with our results checker, and retest after any repair or treatment.
