The short answer

1 result is above EPA’s legal limit. The worst: Total trihalomethanes (TTHM), above the legal limit. 2 health-based violations since 2016.

What handles it

What was found

Total trihalomethanes (TTHM) and haloacetic acids (HAA5): Kansas’s own results, samples taken from Feb. 4, 2020 to Nov. 4, 2025, with EPA’s 2012 to 2019 file for earlier years.

Highest yearly average, 2020 to 2025

2025 average: 39.3 ppb

Averaged by year, the highest was 57 ppb, in 2020, below EPA’s legal limit of 80 ppb. Its highest single sample was 92 ppb. In 2025, the latest year on file, its four samples averaged 39.3 ppb.

  • 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

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) and haloacetic acids (HAA5) results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Franklin Co RWD 2’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 Feb. 4, 2020 to Nov. 4, 2025.

Testing your own tap

Franklin Co RWD 2’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.
