The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. 10 health-based violations since 2016.

What handles it

What was found

Arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride and chromium (total): Texas’s own results, samples taken from Feb. 24, 2020 to July 28, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the health goal2

Above the health goal

5.8ppb

Highest yearly average, 2021 to 2026

2026: not found

Averaged by year, the highest was 5.8 ppb, in 2021: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2026, 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 7.2 ppb, in 2018.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

1.0ppm

Highest sample; found in 16 of 24

2026 average: 0.28 ppm

The highest sample, in 2024, was 1.0 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its five samples averaged 0.28 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.38 ppm, in 2018.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.24ppm

Highest yearly average, 2020 to 2026

2026: not found

Averaged by year, the highest was 0.24 ppm, in 2024, below EPA’s legal limit of 4.0 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 yearly average of 0.25 ppm, in 2012.

What handles it

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

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

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

    For: 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. Arsenic, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride and chromium (total) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Morton Road MUD’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 July 28, 2026.

Testing your own tap

Morton Road MUD’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.
