What to test for in Richmond County

Private wells are not regulated like public water: EPA advises owners to test their well every year for total coliform bacteria, nitrates, total dissolved solids and pH. Your state's own schedule:

  • 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. source
  • DHHS also says well water should be tested after repairs or replacements of well parts and after flooding, and that you should test for nitrates if you are pregnant or have an infant at home. It suggests checking the wellhead once a year for cracks or openings. source

Arsenic. USGS estimates that about 164 people using private wells in Richmond County had arsenic above 10 µg/L, EPA's limit for public water (2010 base year; 95% range 124 to 218). USGS describes this kind of estimate as useful "for broad screening of the population at risk", so it says nothing certain about any one well. Arsenic has no taste or smell: test for it by name.

Radon. EPA puts Richmond County in Zone 3: low potential (average indoor radon may be less than 2 pCi/L). That map is about radon in indoor air, and EPA says it should not be used to decide whether an individual home needs testing. If radon is found in your air and you have a well, EPA suggests testing the water too: see radon in well water.

For anything specific to your home (farms nearby, old plumbing, a new baby, a smell or stain), use the which-tests checklist. When the results arrive, check your numbers against EPA's limits.

PFAS in public water near Richmond County (public supply, not your well)

This is public water data, not your well. A private well draws its own groundwater, which can have more or less PFAS than the public supply nearby. Only a test of your well tells you.

Under EPA’s fifth Unregulated Contaminant Monitoring Rule (UCMR 5), public water systems sampled their water for 29 PFAS between Jan 3, 2023 and Jun 17, 2026. 3 public systems that serve ZIP codes mainly in Richmond County reported results. 3 of them had at least one sample with PFOA or PFOS at or above 4.0 ng/L, and 3 had at least one of the 29 PFAS measured at or above its reporting level.

Public water systems with the highest single PFOA or PFOS result

Hamlet Water SystemNC03770105.76.9
Rockingham, City OfNC03770154.44.9
Richmond County Water SystemNC03771094.7

4.0 ng/L (parts per trillion) is both EPA’s UCMR 5 reporting level for PFOA and PFOS and the number in EPA’s 2024 limit for public water. That limit is judged on a running annual average, so one sample at that level is not a violation. EPA proposed changes to its PFAS rules in May 2026: see PFAS in well water for the current status and who should test a well. To test your own well, find a lab certified for PFAS.

Method: a system counts for this county when it reports serving a ZIP code whose largest land part is in this county, so a system serving several counties counts in each. Source: U.S. EPA, UCMR 5 occurrence data (by state), file dated Oct 15, 2026; downloaded Nov 1, 2026.

Sources and method Private-well population is the USGS 2015 estimate of people on domestic self-supplied water. The arsenic figure is a USGS model estimate on a 2010 population base, not a count of tested wells. Labs are placed in a county by the ZIP code on the state list. These figures come from different USGS products, years and methods, so they can disagree with each other (for example, the arsenic estimate and the well population use different base years). Read them as context for the county, not as facts about any one well. Checked 1 Nov 2026. General information, not medical advice.
