The ZIP code it serves
The short answer
1 result is above EPA’s legal limit, and 1 more is above the health goal. The worst: Arsenic, above the legal limit. 18 health-based violations since 2016.
What handles itWhat was found
Arsenic, uranium, nitrate, fluoride, chromium (total), total trihalomethanes (TTHM) and haloacetic acids (HAA5): Texas’s own results, samples taken from Feb. 18, 2020 to July 7, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Arsenic
Comes from the source
35ppb
Highest yearly average, 2020 to 2026
2026 average: 7.8 ppb
Averaged by year, the highest was 35 ppb, in 2024, about 3.5 times EPA’s legal limit of 10 ppb. Its highest single sample was 41.6 ppb. In 2026, the latest year on file, its three samples averaged 7.8 ppb. EPA recorded violations for arsenic at this utility in 2022, 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 38.8 ppb, in 2012, and EPA recorded violations in 2012, 2013, 2015, 2016 and 2017.

What handles it
No certification claim covers this compound yet.
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
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, nitrate, fluoride, chromium (total), total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Freer WCID’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. 18, 2020 to July 7, 2026.
