The ZIP code it serves
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. 98 health-based violations since 2016.
What handles itWhat was found
Arsenic, fluoride, nitrate, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM) and chromium (total): Texas’s own results, samples taken from Jan. 21, 2020 to July 8, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit2
Arsenic
Comes from the source
36.1ppb
Highest yearly average, 2020 to 2026
2026 average: 26.1 ppb
Averaged by year, the highest was 36.1 ppb, in 2022, about 3.6 times EPA’s legal limit of 10 ppb. Its highest single sample was 40.5 ppb. In 2026, the latest year on file, its three samples averaged 26.1 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 39.9 ppb, in 2012, and EPA recorded violations in 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019.

Fluoride
Forms or is added in treatment
4.8ppm
Highest yearly average, 2020 to 2026
2026 average: 4.5 ppm
Averaged by year, the highest was 4.8 ppm, in 2022, above EPA’s legal limit of 4.0 ppm. Its highest single sample was 5.2 ppm. In 2026, the latest year on file, its three samples averaged 4.5 ppm, above the limit. EPA recorded violations for fluoride 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 4.9 ppm, in 2012, and EPA recorded violations in 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019.

Above the health goal2
Nitrate
Comes from the source
11.1ppm
Highest sample; found in 28 of 28
2026 average: 8.2 ppm
One sample, in 2020, was above EPA’s legal limit of 10 ppm, at 11.1 ppm. The next sample at the same point, within 30 days, brought the average back under the limit. 10 ppm is also EPA’s health goal. In 2026, the latest year on file, its three samples averaged 8.2 ppm. EPA recorded no violation for nitrate at this utility since 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 13 ppm, in 2013, and EPA recorded violations in 2013 and 2014.

Uranium
Comes from the source
10.7ppb
Highest yearly average, 2024
Averaged by year, the highest was 10.7 ppb, in 2024: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10.9 ppb, in 2018.

- 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: Arsenic (Pentavalent)<=50 ppb Reduction, Fluoride, Nitrate/Nitrite (30 ppm challenge)
For: Arsenic, Fluoride, Nitrate
Other certifiers’ wording: Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Fluoride Reduction, Nitrate/Nitrite Reduction, Uranium
For: Arsenic, Fluoride, Nitrate, Uranium
Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level); Nitrate
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, nitrate, uranium, haloacetic acids (HAA5), total trihalomethanes (TTHM) and chromium (total) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Seagraves’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. 21, 2020 to July 8, 2026.
