Best match for Baton Rouge

Whole-house catalytic carbon for chloramine

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.

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

Other options that still fit

  • Do not buy a softener on this supply

    This supply is soft on the published numbers. A salt tank is usually the wrong box unless you are on a well or a different utility. Test the tap before you buy hardness equipment.

    Shop water test kits

  • 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.

Hardness
Hardness, total (as CaCO3) highest detect 52 mg/L, range 0–52, sampled 10/29/2025 on the source secondary-contaminants table. The report says source secondary contaminants are tested immediately at the raw water well. Narrative says the aquifer water has a natural low hardness concentration. — Baton Rouge Water Company 2025 Water Quality Report
Disinfectant
Chloramines 2 ppm highest RAA (range 0.43–3.2), MRDL 4, MRDLG 4. 2025 disinfectant table. Water additive used to control microbes. — Baton Rouge Water Company 2025 Water Quality Report
Brine / salt to the sewer
No district prohibition found in current research. Searched Baton Rouge Water Company and City of Baton Rouge / Parish sewer pages and codes for a residential self-regenerating softener or brine-drain ban like LACSD Measure S. None turned up. 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.

Baton Rouge drinking water is pumped from 101 groundwater wells in the Southern Hills aquifer system and delivered by Baton Rouge Water Company. No Baton Rouge Water or City-Parish 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.

The 2025 report source secondary-contaminants table prints hardness, total (as CaCO3) highest 52 mg/L (range 0–52), sampled at the raw water well. The narrative says that aquifer water has a natural low hardness concentration. We do not invent a finished-water hardness number that table did not print.

Chloramines 2 ppm highest RAA (range 0.43–3.2). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
