The short answer

2 results are above the limit’s level with no violation recorded. The worst: Haloacetic acids (HAA5), above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Haloacetic acids (HAA5) and total trihalomethanes (TTHM): Kansas’s own results, samples taken from July 13, 2020 to July 14, 2026, with EPA’s 2012 to 2019 file for earlier years.

86.7ppb

Highest yearly average, 2020 to 2026

2026, one sample: 50 ppb

Averaged by year, the highest was 86.7 ppb, in 2021, above EPA’s legal limit of 60 ppb. Its highest single sample was 180 ppb. In 2026, the latest year on file, its one sample was 50 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for haloacetic acids (HAA5) at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 52 ppb, in 2015.

  • 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: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

    Other certifiers’ wording: VOC Reduction

  • NSF/ANSI 58

    Claim: Trihalomethanes (TTHM) Reduction

    For: Total trihalomethanes (TTHM)

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. Haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Bronson’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; Kansas’s results run from July 13, 2020 to July 14, 2026.

Testing your own tap

City of Bronson’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 Kansas certifies.
