Kansas City, Missouri
KC Water, Missouri River plus wells. The 2025 Annual Water Quality Report is on their site. Older printed tables had hardness in the 80–130 ppm band — open this year’s file.
This city’s report did not print a number we can put on the chart. Open the current water-quality report. We do not invent a value.
On the report
- Water utility
- KC Water
- Hardness
- 2022 KC Water CCR printed total hardness 85.8–130 ppm. The 2025 report posted June 2026 is the file to open for this year. We are not treating 2022 as 2025. — KC Water Consumer Confidence Reports
- Disinfectant
- Older KC Water tables list total chlorine as the residual. Open the 2025 report for this year’s line. — KC Water Consumer Confidence Reports
- Brine / salt to the sewer
- No district prohibition found in current research. No KC Water sewer ban like Measure S turned up. Ask the wastewater utility on the bill.

Extra context besides the utility report and the chart above — geology, an unregulated table, or a published study. Not a second set of printed tap numbers.
- MicroplasticsWHO’s 2019 review examined studies that found microplastic particles in treated tap and bottled water in many places. That is a published-occurrence finding, not a number from this city’s water-quality report, and we do not invent a particles-per-liter count for the tap.Microplastics in drinking-water — World Health Organization
- PFASEPA’s Fifth Unregulated Contaminant Monitoring Rule required community systems this size to test 29 PFAS and lithium in 2023–2025. Open the UCMR 5 Data Finder for this PWS.

If soap will not lather and the glassware looks chalky
A salt-based softener is the thing that actually removes hardness. Size it from your grains and how much water you use, not bathroom count. It needs a drain.
If you only want less scale and you hate salt bags
A salt-free conditioner changes how scale sticks. It does not soften. Soap and spots stay closer to untreated. No brine line.
If the water tastes like the plant’s disinfectant
Open the CCR for chlorine vs chloramine, then match that claim. A 42 chlorine listing is not chloramine.
If you are shopping a PFAS listing for the kitchen
The under-sink RO we actually run is Cloud RO — NSF/ANSI 58, kitchen tap, not a whole-house tank. Check the exact listing if PFAS is why you are shopping. Waterdrop is a tankless option if you want that path. A certifier-listed pitcher is the cheap first step. Nobody is paying for a medical claim.

If you have not tested the tap
A homeowner kit is a start. It is not a state-certified lab. Use a certified lab when the decision is expensive.
