The short answer

2 results are above EPA’s legal limit, and 2 more are above the health goal. The worst: Arsenic, above the legal limit. 22 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2024.

Arsenic, total trihalomethanes (TTHM), uranium, nitrate, fluoride, haloacetic acids (HAA5) and chromium (total): Texas’s own results, samples taken from Jan. 15, 2020 to July 7, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit2

Arsenic

Comes from the source

Above the legal limit

10.9ppb

Highest yearly average, 2020 to 2026

2026 average: 7.5 ppb

Averaged by year, the highest was 10.9 ppb, in 2021, above EPA’s legal limit of 10 ppb. Its highest single sample was 13.8 ppb. In 2026, the latest year on file, its four samples averaged 7.5 ppb. EPA recorded violations for arsenic at this utility in 2020 and 2021.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the legal limit

61.8ppb

Highest yearly average, 2020 to 2026

2026 average: 13.7 ppb

Averaged by year, the highest was 61.8 ppb, in 2022, below EPA’s legal limit of 80 ppb. Its highest single sample was 169 ppb. In 2026, the latest year on file, its six samples averaged 13.7 ppb. EPA judges this limit at each sampling point, and recorded a violation for total trihalomethanes (TTHM) at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 79.4 ppb, in 2016, and EPA recorded violations in 2016, 2017 and 2019.

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

4.1ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 4.1 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.

What handles it

Uranium

Comes from the source

Above the health goal

6.2ppb

Highest yearly average, 2022 to 2025

2025, one sample: 2.9 ppb

Averaged by year, the highest was 6.2 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 6.6 ppb. In 2025, the latest year on file, its one sample was 2.9 ppb.

What handles it

Below EPA’s limits4

Nitrate

Comes from the source

Below EPA’s limits

10.3ppm

Highest sample; found in 34 of 34

2026 average: 7.8 ppm

The highest sample, in 2026, was 10.3 ppm, which EPA rounds to 10 ppm to compare: at its legal limit of 10 ppm, not above it. That was also the latest year on file, and its four samples averaged 7.8 ppm. EPA recorded no violation for nitrate at this utility since 2020.

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

    For: Arsenic, Total trihalomethanes (TTHM), Lead

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

  • NSF/ANSI 58

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

    For: Arsenic, Total trihalomethanes (TTHM), Lead, Uranium

    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. Arsenic, total trihalomethanes (TTHM), uranium, nitrate, fluoride, haloacetic acids (HAA5) and chromium (total) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Stanton’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 Jan. 15, 2020 to July 7, 2026.

Testing your own tap

City of Stanton’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.

No lab Texas certifies is within 75 miles of the area City of Stanton serves on the state’s list. Some take samples by mail; the state’s page lists them all.

Texas Well Owner Network, Texas A&M AgriLife Extension: Well Informed screening events, where well owners bring in water samples to be screened for common contaminants, followed by an hour-long session explaining the results. Upcoming events are on the network's calendar. Trainings, Texas Well Owner Network.
