The short answer

1 result is above EPA’s legal limit. The worst: Arsenic, above the legal limit. 4 health-based violations since 2016.

What handles it

What was found

Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, chromium (total), nitrate and uranium: Texas’s own results, samples taken from Dec. 18, 2020 to Sept. 8, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Arsenic

Comes from the source

Above the legal limit

11.6ppb

Highest yearly average, 2020 to 2026

2026 average: 4.9 ppb

Averaged by year, the highest was 11.6 ppb, in 2024, above EPA’s legal limit of 10 ppb. Its highest single sample was 12.2 ppb. In 2026, the latest year on file, its three samples averaged 4.9 ppb. EPA recorded violations for arsenic at this utility in 2023, 2024 and 2025. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 11.1 ppb, in 2012, and EPA recorded violations in 2012 and 2013.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Below EPA’s limits3

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

2024, one sample: 46 ppb

Averaged by year, the highest was 48.1 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2024, the latest year on file, its one sample was 46 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 48.1 ppb, in 2017.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

10ppb

Highest yearly average, 2021 to 2024

2024, one sample: 7.9 ppb

Averaged by year, the highest was 10 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2024, the latest year on file, its one sample was 7.9 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 6.5 ppb, in 2018.

What handles it

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.64ppm

Highest yearly average, 2022 to 2025

Averaged by year, the highest was 0.64 ppm, in 2025, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 0.68 ppm, in 2019.

What handles it

4 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Chromium (total)
  • Lead
  • Nitrate
  • Uranium

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: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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. Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, chromium (total), nitrate and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Timer 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 Dec. 18, 2020 to Sept. 8, 2026.

Testing your own tap

Timer 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 Timer Water System serves on the state’s list. Some take samples by mail; the state’s page lists them all.
