The short answer
1 result is above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 13 health-based violations since 2016.
What handles itWhat was found
Total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, nitrate, arsenic, chromium (total) and uranium: Texas’s own results, samples taken from March 12, 2020 to Sept. 1, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit1
Total trihalomethanes (TTHM)
Forms or is added in treatment
156ppb
Highest yearly average, 2020 to 2026
2026 average: 149 ppb
Averaged by year, the highest was 156 ppb, in 2025, about twice EPA’s legal limit of 80 ppb. Its highest single sample was 231 ppb. In 2026, the latest year on file, its six samples averaged 149 ppb, above the limit. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2022, 2023, 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 229 ppb, in 2013, and EPA recorded a violation in 2015.

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: Trihalomethanes (TTHM) Reduction

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), fluoride, nitrate, arsenic, chromium (total) and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Crystal Farms WSC’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 March 12, 2020 to Sept. 1, 2026.
