The short answer

1 result is above EPA’s legal limit, and 2 more are above the health goal. The worst: Fluoride, above the legal limit. 8 health-based violations since 2016.

What handles it

What was found

Fluoride, arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), chromium (total) and nitrate: Texas’s own results, samples taken from Feb. 13, 2020 to July 7, 2026, with EPA’s 2012 to 2019 file for earlier years.

2026 average: 4.0 ppm

Averaged by year, the highest was 4.1 ppm, in 2022, above EPA’s legal limit of 4.0 ppm. Its highest single sample was 4.2 ppm. In 2026, the latest year on file, its three samples averaged 4.0 ppm. EPA recorded a violation for fluoride at this utility in 2022. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.1 ppm, in 2013, and EPA recorded violations in 2017 and 2018.

Below EPA’s limits

5.5ppb

Highest yearly average, 2022 to 2025

2025: not found

Averaged by year, the highest was 5.5 ppb, in 2022, below EPA’s legal limit of 100 ppb. In 2025, the latest year on file, it wasn’t found in its one sample. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.9 ppb, in 2016.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.35ppm

Highest sample; found in 7 of 7

2026, one sample: 0.28 ppm

The highest sample, in 2021, was 0.35 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 0.28 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.4 ppm, in 2017.

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

    Claims: Fluoride, Arsenic (Pentavalent)<=50 ppb Reduction

    For: Fluoride, Arsenic

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

  • NSF/ANSI 58

    Claims: Fluoride Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Fluoride, Arsenic, Uranium

    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. Fluoride, arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), chromium (total) and nitrate results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Umbarger Community Water Supply’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 7, 2026.

Testing your own tap

Umbarger Community Water Supply’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.
