The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Uranium, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and nitrate: North Carolina’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from Oct. 23, 2012 to Oct. 16, 2018. Newer results are in the utility’s annual water quality report.

2.4ppb

Highest yearly average, 2022

Averaged by year, the highest was 2.4 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.0 ppb, in 2019.

2018, one sample: 1.6 ppm

Averaged by year, the highest was 1.7 ppm, in 2015, below EPA’s legal limit of 4.0 ppm. In 2018, the latest year on file, its one sample was 1.6 ppm.

11.9ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 11.9 ppb, in 2023, below EPA’s legal limit of 60 ppb. That was also the latest year on file.

  • Arsenic
  • Chromium (total)
  • Lead
  • Nitrate

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

At the tap, or for the whole house?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. How whole-house systems compare.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

What this report can’t tell you

  • Everything else. Uranium, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and nitrate results here are North Carolina’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Nantucket Village’s own annual report, which it must send you every year, has newer results for those and the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; CDC’s yearly averages for North Carolina cover 2020 to 2023; EPA’s compliance samples are from Oct. 23, 2012 to Oct. 16, 2018.

Testing your own tap

Nantucket Village’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab North Carolina certifies.
