Ventura, California

Ventura Water 2025 Consumer Confidence Report (2024 data). Hardness prints as three labeled columns — Ventura River 418 ppm / 24 gpg, groundwater 637 ppm / 37 gpg, Casitas 297 ppm / 17 gpg. Chloramine 2.5 ppm highest RAA. No Measure S-style residential softener ban ordinance opened — check the sewer agency on the bill.

Salt-based water softener — confirm the district first

Two tall mineral tanks and a black brine tank of a salt-based water softener, plumbed with copper pipe in a garage.
Salt-based softener: two mineral tanks and a brine tank.

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.

    Shop salt-free conditioners

  • Whole-house catalytic carbon for chloramine

    Catalytic carbon with a chloramine claim (NSF/ANSI 42 for chloramine). Regular chlorine carbon is the wrong box.

  • 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.

Brine / salt to the sewer
Check the sanitation district before installing. No Ventura Water or City of Ventura residential self-regenerating softener ban like LACSD Measure S turned up. That is not a statewide ban finding. Ask the sewer agency on the bill before you cut 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

Ventura drinking water is Ventura River water, local groundwater, and Casitas Municipal Water District water delivered by Ventura Water. No City of Ventura 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 Consumer Confidence Report (2024 data) prints hardness as three labeled columns — Ventura River 418 ppm (range 402–448), also 24 gpg; groundwater 637 ppm (range 489–911), also 37 gpg; and Casitas 297 ppm / 17 gpg. We do not invent a citywide blend.

Chloramine residual 2.5 ppm highest RAA (range 0.1–4.0). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
