Trinidad, California

City of Trinidad 2023 Consumer Confidence Report. Hardness 3 / 12 / 13 / 17 on a labeled hardness row in the 2023 tables. The row is not labeled as CaCO3 in the extracted text, so this file does not assign a hardness class from it. The 2023 booklet lists chlorine as the residual disinfectant. A single residual average did not extract cleanly from the text layer. Open the current report. No Measure S-style ban turned up — check the sewer agency on the bill.

Best match for Trinidad

Whole-house carbon for chlorine

A single black whole-house carbon tank with a control head, installed in a garage and connected to copper pipe.
Whole-house carbon tank. No brine tank.

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.

Brine / salt to the sewer
Check the sanitation district before installing. No city or sanitation-district residential self-regenerating softener ban like LACSD Measure S or IEUA Ordinance § 2.6 turned up on the pages we opened. That is not a statewide ban finding. Ask the agency on the sewer bill before you cut a brine drain.
