Woodland, California
City of Woodland 2025 Annual Water Quality Report (PWS 5710006). Surface water from WDCWA is the primary supply. Hardness prints as 4.06 grains/gal (range 3.39–5.09) and total hardness as CaCO3 69.4 (range 58–87) on the unregulated table. Chlorine 0.73 ppm. No Measure S-style residential softener ban turned up — check the sewer agency on the bill.

Best match for Woodland
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 Woodland Utilities
- Hardness
- Unregulated table, 2025, one citywide row. Hardness 4.06 grains/gal (range 3.39–5.09). Hardness, Total [as CaCO3] printed unit “(ppb)” 69.4 (range 58–87). Companion grains row is 4.06 gpg. Those are the printed rows — we do not invent a blended ppm from the unit label. Not two source columns. — City of Woodland 2025 Annual Water Quality Report
- Disinfectant
- Chlorine 0.73 ppm (range 0.20–1.17), MRDL 4.0 as Cl2, 2025 distribution. Printed as chlorine. Treatment text says sodium hypochlorite (chlorine). — City of Woodland 2025 Annual Water Quality Report
- Sanitation district
- City of Woodland (WPCF / sewer)
- Brine / salt to the sewer
- Check the sanitation district before installing. Opened Woodland ecode360 Article 2 Discharge Requirements. No self-regenerating / brine-softener install prohibition like LACSD Measure S or IEUA § 2.6. City materials tell residents they may reduce or discontinue softeners after the WDCWA surface-water switch — that is education, not a ban. Ask Public Works or the agency on the sewer bill 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
- Hexavalent chromiumThe 2025 regulated table prints hexavalent chromium 12.26 ppb (range 0.75–31), MCL 10. Footnote 3 says wells with elevated Cr6 were not pumped to distribution in 2025 and a system this size is not in violation until after October 1, 2027. That is the report’s labeled row, not a tap average we invented.12.26 ppb (range 0.75–31), MCL 10 — footnote 3 on the 2025 table.2025 Annual Water Quality Report (PWS 5710006) — City of Woodland Utilities
- 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
Woodland drinking water in 2025 was more than 99 percent WDCWA Sacramento River surface water, with aquifer-storage and blending wells as backup. Opened sewer discharge rules do not print a Measure S-style residential self-regenerating install ban. Ask Public Works or the agency on the sewer bill before you cut a brine drain. This is not a legal opinion.
The 2025 unregulated table prints hardness 4.06 grains/gal (range 3.39–5.09) and total hardness as CaCO3 69.4 (range 58–87) with the printed unit “(ppb).” Those are the labeled rows. We do not invent a second column.
Chlorine 0.73 ppm (range 0.20–1.17). Hexavalent chromium 12.26 ppb (range 0.75–31) on the regulated table. Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
