How the North Carolina list marks public samples (whole list). County and district health departments: marked from NC DHHS's private-well testing FAQ, which tells well owners to contact their local health department to request well water testing. Other labs: not stated per lab.
Before you send a sample, call the lab to confirm it is currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Status can change between list updates.
Why test for coliform bacteria in North Carolina
About a third of the 397 domestic wells tested for bacteria in a national USGS study had total coliform. Read our coliform bacteria explainer.
EPA advises private-well owners to test every year for total coliform bacteria, nitrates, total dissolved solids and pH. [1]
North Carolina guidance that mentions coliform bacteria:
- NC DHHS recommends testing a private well every year for total and fecal coliform bacteria, every two years for heavy metals, nitrates, nitrites, lead and copper, and every five years for pesticides and volatile organic compounds (VOCs). If you know of a particular pesticide applied in your area, it says to test for it yearly. [2]
- All newly constructed private wells in North Carolina must be tested by the State Laboratory of Public Health (scheduled through your local health department) or a state-certified commercial lab before the well is used as a drinking water source. DHHS says the tests for bacterial and chemical contaminants should be done within 30 days of well completion. [2]
- The State Laboratory of Public Health tests samples from new or existing private wells for coliform bacteria only if the sample is submitted through a local health department. Results show the presence or absence of total coliform and E. coli and are sent within two working days after the lab receives the sample. [3]
About 2,407,661 people in North Carolina used private wells in 2015, by the USGS estimate of people on domestic self-supplied water. [4] Federal limits are written for public water systems, not private wells, so testing is up to the owner.
For tests that depend on your home (farms nearby, old plumbing, a new baby), use the which-tests checklist. When results arrive, check your numbers against EPA's limits. State guidance, county data and every lab: North Carolina.
