The short answer

2 results are above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 2 health-based violations since 2016.

What handles it

What was found

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.4 ppm, for the period ending Dec. 31, 2012. None since is on file, so it is not counted as a current finding.

Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: Texas’s own results, samples taken from Sept. 23, 2020 to Sept. 9, 2026, with EPA’s 2012 to 2019 file for earlier years.

Total trihalomethanes (TTHM)

Above the legal limit

168ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 168 ppb, in 2026, about twice EPA’s legal limit of 80 ppb. Its highest single sample was 238 ppb. That was also the latest year on file. EPA recorded a violation for total trihalomethanes (TTHM) at this utility in 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 32.2 ppb, in 2014.

  • NSF/ANSI 58 look for “Trihalomethanes (TTHM) Reduction”

Haloacetic acids (HAA5)

Forms or is added in treatment

Above the legal limit

52.1ppb

Highest yearly average, 2020 to 2026

Averaged by year, the highest was 52.1 ppb, in 2026, below EPA’s legal limit of 60 ppb. Its highest single sample was 65.5 ppb. That was also the latest year on file. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 32.7 ppb, in 2013.

2026, one sample: 3.6 ppm

The highest sample, in 2026, was 3.6 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and its one sample was 3.6 ppm.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
One compound tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • 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. Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Rra Northeast Quanah Water System’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; Texas’s results run from Sept. 23, 2020 to Sept. 9, 2026.

Testing your own tap

Rra Northeast Quanah Water System’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 Texas certifies.

No lab Texas certifies is within 75 miles of the area Rra Northeast Quanah Water System serves on the state’s list. Some take samples by mail; the state’s page lists them all.
