The ZIP code it serves
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 itWhat 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.
Above the health goal1
Uranium
Comes from the source
3.4ppb
Highest yearly average, 2020 to 2021
Averaged by year, the highest was 3.4 ppb, in 2021: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That was also the latest year on file.
What handles it
- NSF/ANSI 58 look for “Uranium”
Below EPA’s limits2
Total trihalomethanes (TTHM)
Forms or is added in treatment
12ppb
Highest yearly average, 2020 to 2022
2022: not found
Averaged by year, the highest was 12 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2022, the latest year on file, it wasn’t found.
What handles it
- NSF/ANSI 53 look for “Trihalomethanes (TTHM) Reduction”
- NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”
Haloacetic acids (HAA5)
Forms or is added in treatment
3.1ppb
Highest yearly average, 2020 to 2022
2022: not found
Averaged by year, the highest was 3.1 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2022, the latest year on file, it wasn’t found.

- Arsenic
- 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.”

Claim: Uranium
For: Uranium
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. Chinquapin Development’s own annual report, which it must send you every year, has 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.
