The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Total trihalomethanes (TTHM), above the legal limit. 27 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2023.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium: Texas’s own results, samples taken from Feb. 19, 2020 to Sept. 15, 2026, with EPA’s 2012 to 2019 file for earlier years.

Above the legal limit

87.8ppb

Highest yearly average, 2020 to 2026

2026 average: 77 ppb

Averaged by year, the highest was 87.8 ppb, in 2024, above EPA’s legal limit of 80 ppb. Its highest single sample was 172 ppb. In 2026, the latest year on file, its six samples averaged 77 ppb. EPA recorded violations for total trihalomethanes (TTHM) at this utility in 2024, 2025 and 2026. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 71.5 ppb, in 2017, and EPA recorded violations in 2015, 2016, 2018 and 2019.

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, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claims: Trihalomethanes (TTHM) Reduction, Lead Reduction

    For: Total trihalomethanes (TTHM), Lead

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate, fluoride, arsenic, chromium (total) and uranium results here are Texas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Junction’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. 19, 2020 to Sept. 15, 2026.

Testing your own tap

City of Junction’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.
