The short answer

2 results are above EPA’s legal limit. The worst: Haloacetic acids (HAA5), above the legal limit. 13 health-based violations since 2016.

What handles it

What was found

Haloacetic acids (HAA5) and total trihalomethanes (TTHM): 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.

Averaged by year, the highest was 53 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 51.8 ppb. EPA judges this limit at each sampling point, and recorded violations for total trihalomethanes (TTHM) at this utility in 2020 and 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 67 ppb, in 2013, and EPA recorded violations in 2013, 2017 and 2019.

  • Lead

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.”

  • NSF/ANSI 53

    Claim: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claim: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

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.

What this report can’t tell you

  • Everything else. Haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are North Carolina’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Rockingham Co - 220 Corridor’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.

Testing your own tap

Rockingham Co - 220 Corridor’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.
