The short answer

1 result is above the limit’s level with no violation recorded, and 2 more are above the health goal. The worst: Total trihalomethanes (TTHM), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 2014 to 2026.

Total trihalomethanes (TTHM), uranium, haloacetic acids (HAA5), fluoride, nitrate, arsenic and chromium (total): Texas’s own results, samples taken from July 15, 2020 to Sept. 15, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the limit’s level, no violation recorded1

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the limit’s level, no violation

109ppb

Highest yearly average, 2022 to 2026

2026 average: 59 ppb

Averaged by year, the highest was 109 ppb, in 2025, above EPA’s legal limit of 80 ppb. Its highest single sample was 137 ppb. In 2026, the latest year on file, its two samples averaged 59 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 22.6 ppb, in 2016.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

3.1ppb

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 3.1 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.

Above the health goal

1.7ppb

Highest yearly average, 2020 to 2022

Averaged by year, the highest was 1.7 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 3.0 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.6 ppb, in 2016.

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, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction, Uranium

    For: Total trihalomethanes (TTHM), Lead, Uranium

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), uranium, haloacetic acids (HAA5), fluoride, nitrate, arsenic and chromium (total) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Camp Stanley’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 July 15, 2020 to Sept. 15, 2026.

Testing your own tap

Camp Stanley’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.
