2 results are above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 17 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: Texas’s own results, samples taken from Feb. 13, 2020 to July 16, 2026, with EPA’s 2012 to 2019 file for earlier years.

194ppb

Highest yearly average, 2020 to 2026

2026 average: 7.4 ppb

Averaged by year, the highest was 194 ppb, in 2021, about 2.4 times EPA’s legal limit of 80 ppb. Its highest single sample was 492 ppb. In 2026, the latest year on file, its six samples averaged 7.4 ppb. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2021, 2022, 2023 and 2024.

Nitrate

1.1ppm

Highest sample; found in 6 of 6

2026, one sample: 1.0 ppm

The highest sample, in 2020, was 1.1 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 1.0 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. Comanche County WSC Sipe Springs’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 Feb. 13, 2020 to July 16, 2026.

Testing your own tap

Comanche County WSC Sipe Springs’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.
