Anaheim Public Utilities 2025 Water Quality Report. Groundwater, Lenain plant, and MWD columns. Hardness 318 / 288 / 271 ppm. No Measure S-style residential softener ban turned up. That is not a statewide ban finding — ask the sewer agency on the bill.

Best match for Anaheim
Salt-based water softener
No district prohibition on a brine drain turned up in the current file.

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.

Other options that still fit
Salt-free conditioner
A salt-free conditioner changes how scale sticks. It does not soften. Soap and spots stay closer to untreated. No brine line.
Whole-house carbon for chlorine
That is chlorine. A whole-house carbon filter with an NSF/ANSI 42 chlorine claim is the usual match. A softener will not take chlorine out.
Under-sink reverse osmosis
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.

Test the tap first
A homeowner kit is a start. It is not a state-certified lab. Use a certified lab when the decision is expensive.

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

Anaheim drinking water is a blend of Orange County groundwater and imported water, with untreated imported water also treated at the Lenain plant. No Anaheim or Orange County Sanitation District residential softener ban like LACSD Measure S turned up. Ask the sewer agency on the bill before you cut a brine drain. This is not a legal opinion and not a statewide ban.
The 2025 Water Quality Report prints hardness as three labeled columns — groundwater 318 ppm as CaCO3 (19 grains), Lenain 288 ppm (17 grains), and MWD 271 ppm (16 grains). Range of detections 135–431 ppm. We do not invent a citywide blend.
Chlorine residual 1.0 ppm (range ND–2.6). TTHMs highest LRAA 55 ppb (range 20–82). HAA5 highest LRAA 10 ppb (range 2.1–14). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
