Minneapolis, Minnesota
Mississippi River water treated by Minneapolis Public Works. Open the city’s plant-effluent analysis and CCR for the year’s hardness and residual. This file does not copy a dealer blog.
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
- Hardness
- Printed on the city’s yearly plant-effluent water analysis, not invented here. Open that PDF for the year you care about. — Minneapolis plant effluent water analysis
- Disinfectant
- The city publishes chloramine / disinfectant residuals on the same plant-effluent tables and the annual CCR. Open the current file. — Minneapolis water quality reports
- Brine / salt to the sewer
- No district prohibition found in current research. No Minneapolis or Met Council sewer ban like Measure S turned up. Ask the wastewater utility on the bill.
Also around here
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. This file does not invent a detection.Fifth Unregulated Contaminant Monitoring Rule — U.S. Environmental Protection Agency

If a dealer is selling hardness equipment


Open the current CCR for grains. This file does not invent a number from a ranking site. A salt softener needs a drain if it is legal at the address.

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.
