The short answer
Nothing in EPA’s and Kansas’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. No health-based violations on file since 2016.
What was found
Total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, chromium (total), arsenic and nitrate: Kansas’s own results, samples taken from March 16, 2020 to Sept. 2, 2026, with EPA’s 2012 to 2019 file for earlier years.

3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
- Arsenic
- Lead
- Nitrate
Hardness
Very hard, typically 218 mg/L (12.7 grains per gallon), across 2 sampling points, 2017 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.
Violations since 2016
No health-based violations on file with EPA since 2016. There are 2 monitoring or reporting violations: a sample missed, late or not reported.
What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, chromium (total), arsenic and nitrate results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. Franklin Co RWD 5’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 March 16, 2020 to Sept. 2, 2026.
