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: Total trihalomethanes (TTHM), above the legal limit. 47 health-based violations since 2016.
What handles itWhat was found
Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, uranium, nitrate, fluoride and chromium (total): Texas’s own results, samples taken from Feb. 24, 2020 to Aug. 3, 2026, with EPA’s 2012 to 2019 file for earlier years.

- 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: Trihalomethanes (TTHM) Reduction, Arsenic (Pentavalent)<=50 ppb Reduction
For: Total trihalomethanes (TTHM), Arsenic
Other certifiers’ wording: VOC Reduction; Arsenic (III) (50 ppb influent level)
- NSF/ANSI 58
Claims: Trihalomethanes (TTHM) Reduction, Arsenic (Pentavalent)<=50 ppb Reduction, Uranium
For: Total trihalomethanes (TTHM), 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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic, uranium, nitrate, fluoride and chromium (total) results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Strawn’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 Aug. 3, 2026.
