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. 14 health-based violations since 2016.
What was found
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 1.4 ppm, for the period ending Dec. 31, 2010. None since is on file, so it is not counted as a current finding.
Nitrate, fluoride, haloacetic acids (HAA5), total trihalomethanes (TTHM), arsenic and chromium (total): Kansas’s own results, samples taken from Feb. 26, 2020 to Aug. 5, 2026, with EPA’s 2012 to 2019 file for earlier years.

Nitrate
Comes from the source
10ppm
Highest sample; found in 14 of 14
2026, one sample: 9.5 ppm
The highest sample, in 2024, was 10 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 9.5 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 15 ppm, in 2014, and EPA recorded violations in 2012, 2013, 2014, 2015, 2016, 2017 and 2018.

- Arsenic
- Chromium (total)
- Lead
Hardness
Moderately hard, typically 113 mg/L (6.6 grains per gallon), across 2 sampling points, 2015 to 2024.
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. Nitrate, fluoride, haloacetic acids (HAA5), total trihalomethanes (TTHM), arsenic and chromium (total) results here are Kansas’s own from 2020 on, with EPA’s national file for 2012 to 2019. City of Norwich’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. 26, 2020 to Aug. 5, 2026.
