Lodi, California
City of Lodi Annual Water Quality Report for 2025 (published May 2026). Total hardness 133 ppm / 7.8 gpg (range 14–340). Chlorine 0.74 ppm. City materials discourage self-regenerating units for WPCF salinity — that is not a Measure S-style ban. Check the sewer agency on the bill.

Salt-based water softener — confirm the district first
Check the sanitation district before installing a salt system.

Ask the agency on the sewer side of the bill before you cut a brine drain. California lets districts restrict self-regenerating units. A “banned in California” blog is not your district.

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.
On the report
- Water utility
- City of Lodi Water Utility
- Hardness
- Other non-regulated constituents, 2023–2025 data, one hardness pair. Total Hardness 133 ppm as CaCO3 (range 14–340). Total Hardness 7.8 grains/gal (range 0.8–19.9). Not two source columns. — City of Lodi Annual Water Quality Report for 2025
- Disinfectant
- Chlorine 0.74 ppm average (range 0.4–1.2), MCL/MRDL 4, 2025. Printed as chlorine. Narrative calls it low level chlorination. — City of Lodi Annual Water Quality Report for 2025
- Sanitation district
- City of Lodi (WPCF / sewer)
- Brine / salt to the sewer
- Check the sanitation district before installing. Opened Lodi Municode Title 13 water service. No residential self-regenerating install prohibition. City salinity materials discourage self-regenerating units because brine raises WPCF salinity — that is not a Measure S-style ban. Ask Public Works before a brine drain.

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
- ArsenicThe 2025 report prints arsenic 3.8 ppb (range ND–8.1). That is the labeled row, not a blended tap average we invented.3.8 ppb (range ND–8.1), MCL 10.Annual Water Quality Report for 2025 — City of Lodi Water Utility

Lodi drinking water is delivered by the City of Lodi Water Utility. Opened Title 13 water-service rules do not print a Measure S-style residential self-regenerating install ban. City salinity materials discourage those units because brine loads the WPCF. Ask Public Works before you cut a brine drain. This is not a legal opinion.
The 2025 report prints total hardness 133 ppm / 7.8 gpg (range 14–340 ppm). Chlorine 0.74 ppm (range 0.4–1.2). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
