Best match for Tacoma
Whole-house carbon for chlorine
No district prohibition on a brine drain turned up in the current file.
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.

Other options that still fit
Confirm hardness on the current CCR before buying
Open the current CCR for grains. This file does not invent a number from a ranking site. A salt softener needs a drain if it is legal at the address.

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
- Tacoma Water
- Hardness
- Not printed on the official 2025 Water Quality Table we opened. Unknown — no hardness bar invented. — Tacoma Water 2025 Water Quality Table (hardness not printed)
- Disinfectant
- Chlorine residual range 0.27 to 1.66 ppm. Allowed 4 ppm. MRDLG 4 ppm. Running annual average printed as N/A on that row. Treatment additive. 2025 distribution-system table. — Tacoma Water 2025 Water Quality Table
- Brine / salt to the sewer
- No district prohibition found in current research. Searched Tacoma Water / TPU and City of Tacoma 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.
- 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
- PFASThe 2025 report narrative says UCMR5 found no PFAS or lithium in the Green River supply, and two PFAS compounds in groundwater below state action levels. Open the report for those labeled results. This file does not invent a citywide ppt average.2025 Water Quality Report — Tacoma Water
Tacoma drinking water is treated from the Green River supply plus groundwater and delivered by Tacoma Water. No Tacoma Water or City of Tacoma 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 official 2025 Water Quality Table we opened does not print hardness. We do not invent a ppm or grains bar.
Chlorine residual 0.27 to 1.66 ppm. TTHMs running annual average 12.8 ppb (range 3.58–35.4). HAA5 2.0 ppb (range less than 1 to 4.55). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
