The ZIP code it serves
The short answer
2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Haloacetic acids (HAA5), above the legal limit. 5 health-based violations since 2016.
What handles itWhat was found
Lead and copper: EPA SDWIS monitoring periods ending 2007 to 2023.
Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride, chromium (total) and arsenic: Kansas’s own results, samples taken from Jan. 26, 2020 to July 19, 2026, with EPA’s 2012 to 2019 file for earlier years.
Above the legal limit2
Haloacetic acids (HAA5)
Forms or is added in treatment
93.5ppb
Highest yearly average, 2020 to 2026
2026 average: 34.3 ppb
Averaged by year, the highest was 93.5 ppb, in 2024, above EPA’s legal limit of 60 ppb. Its highest single sample was 200 ppb. In 2026, the latest year on file, its three samples averaged 34.3 ppb. EPA recorded a violation for haloacetic acids (HAA5) at this utility in 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 63 ppb, in 2013.
What handles it

Total trihalomethanes (TTHM)
Forms or is added in treatment
75ppb
Highest yearly average, 2020 to 2026
2026 average: 39.3 ppb
Averaged by year, the highest was 75 ppb, in 2024, below EPA’s legal limit of 80 ppb. Its highest single sample was 130 ppb. In 2026, the latest year on file, its three samples averaged 39.3 ppb. EPA judges this limit at each sampling point, and recorded a violation for total trihalomethanes (TTHM) at this utility in 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 99 ppb, in 2016.

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.

Hardness
Very hard, 320 mg/L (18.7 grains per gallon), at its one sampling point, 2015 to 2026.
Hardness is calcium and magnesium. EPA sets no limit for it: it shows up as scale on fixtures and in water heaters, and as soap that won’t lather. USGS calls water above 60 mg/L moderately hard, above 120 hard and above 180 very hard.

What this report can’t tell you
Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM), nitrate, fluoride, chromium (total) and arsenic results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Florence’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 Jan. 26, 2020 to July 19, 2026.
