2 results are above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 5 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, nitrate, arsenic, chromium (total) and uranium: Texas’s own results, samples taken from Sept. 22, 2020 to Sept. 17, 2026, with EPA’s 2012 to 2019 file for earlier years.

81.4ppb

Highest yearly average, 2020 to 2026

2026 average: 7.2 ppb

Averaged by year, the highest was 81.4 ppb, in 2022, above EPA’s legal limit of 80 ppb. Its highest single sample was 120 ppb. In 2026, the latest year on file, its six samples averaged 7.2 ppb. EPA recorded a violation for total trihalomethanes (TTHM) at this utility in 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 64.3 ppb, in 2014.

34.9ppb

Highest yearly average, 2020 to 2026

2026: not found

Averaged by year, the highest was 34.9 ppb, in 2022, below EPA’s legal limit of 60 ppb. Its highest single sample was 92 ppb. In 2026, the latest year on file, it wasn’t found in any of its six samples. EPA judges this limit at each sampling point, and recorded a violation for haloacetic acids (HAA5) at this utility in 2023. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 22.1 ppb, in 2012.

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), fluoride, nitrate, arsenic, chromium (total) and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Hollands Quarter WSC’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. 22, 2020 to Sept. 17, 2026.

Testing your own tap

Hollands Quarter WSC’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.
