Hales Corners, Wisconsin

Milwaukee Water Works 2023 Annual Water Quality Report (opened via archive.org after the city CDN returned 403). Hales Corners is named as a wholesale or retail customer on page 1. The opened 2023 Milwaukee Water Works report does not print a usable hardness-as-CaCO3 number in the extracted text. This file does not invent one. Treatment narrative: chlorine is added after filtration, then ammonia converts it to chloramine. Total chlorine 1.55 ppm (1.46–1.64) on the 2023 table, MRDL 4. No Measure S-style residential softener ban turned up.

Under-sink reverse osmosis

Under-sink reverse osmosis system with a white storage tank, filter canisters, and colored tubing in a kitchen cabinet.
Under-sink reverse osmosis: filters, tank, and a second faucet.

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. Shop Amazon first for under-sink RO, or buy Cloud direct. 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.
