The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 18 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2015 to 2024.

Total trihalomethanes (TTHM), arsenic, fluoride, haloacetic acids (HAA5), chromium (total), nitrate and uranium: Texas’s own results, samples taken from March 12, 2020 to Aug. 10, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit1

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

90.9ppb

Highest yearly average, 2020 to 2026

2026 average: 43.8 ppb

Averaged by year, the highest was 90.9 ppb, in 2021, above EPA’s legal limit of 80 ppb. Its highest single sample was 101 ppb. In 2026, the latest year on file, its three samples averaged 43.8 ppb. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2020, 2021, 2023 and 2025. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 94.6 ppb, in 2015, and EPA recorded violations in 2015, 2016, 2017 and 2019.

Above the health goal

6.9ppb

Highest yearly average, 2021 to 2024

2024, one sample: 6.8 ppb

Averaged by year, the highest was 6.9 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2024, the latest year on file, its one sample was 6.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.1 ppb, in 2018.

What handles it

Above the health goal

1.0ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 1.0 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Below EPA’s limits2

What handles it

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

26.1ppb

Highest yearly average, 2020 to 2026

2026 average: 12.6 ppb

Averaged by year, the highest was 26.1 ppb, in 2020, below EPA’s legal limit of 60 ppb. Its highest single sample was 31.2 ppb. In 2026, the latest year on file, its three samples averaged 12.6 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 29.2 ppb, in 2015.

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

    Claims: Trihalomethanes (TTHM) Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Arsenic, Lead

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

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Arsenic, Lead

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

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), arsenic, fluoride, haloacetic acids (HAA5), chromium (total), nitrate and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Timber Ridge Section 2’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 March 12, 2020 to Aug. 10, 2026.

Testing your own tap

Timber Ridge Section 2’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.
