The short answer
1 result is above EPA’s legal limit. The worst: Arsenic, above the legal limit. 58 health-based violations since 2016.
What handles itWhat was found
Arsenic, fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, chromium (total) and uranium: Texas’s own results, samples taken from Feb. 24, 2020 to Aug. 3, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Arsenic
Comes from the source
16.1ppb
Highest yearly average, 2020 to 2026
2026 average: 12.7 ppb
Averaged by year, the highest was 16.1 ppb, in 2021, above EPA’s legal limit of 10 ppb. Its highest single sample was 27.2 ppb. In 2026, the latest year on file, its six samples averaged 12.7 ppb, above the limit. EPA recorded violations for arsenic at this utility in 2020, 2021, 2022, 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 14.2 ppb, in 2017, and EPA recorded violations in 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019.

1.7ppm
Highest yearly average, 2021 to 2024
Averaged by year, the highest was 1.7 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 1.8 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.8 ppm, in 2012.

No certification claim covers this compound yet.
Nitrate
Comes from the source
0.13ppm
Highest sample; found in 12 of 14
2026: not found
The highest sample, in 2020, was 0.13 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, it wasn’t found in any of its two samples. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.12 ppm, in 2019.
What handles it
- NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
- NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”
3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- Chromium (total)
- Lead
- 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, fluoride, total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, chromium (total) and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Eol 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 Feb. 24, 2020 to Aug. 3, 2026.
