Whole-house catalytic carbon for chloramine
No district prohibition on a brine drain turned up in the current file.
Catalytic carbon with a chloramine claim (NSF/ANSI 42 for chloramine). Regular chlorine carbon is the wrong box.

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.

- Hardness
- The opened 2024 City of Durham CCR does not print total hardness as CaCO3. This file does not invent a hardness number. This is not the Durham County system. — City of Durham 2024 Consumer Confidence Report
- Disinfectant
- Chlorine 2.0 ppm RAA, MRDL 4. Chloramines 2.1 ppm (range 2.0–2.1), MRDL 4, 2024. Chloramine is in play. — City of Durham 2024 Consumer Confidence Report
- Brine / salt to the sewer
- No district prohibition found in current research. Searched city water and sewer pages 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
- 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.

Durham drinking water on this file is City of Durham Department of Water Management — not Durham County. Searched city water and sewer pages 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. This is not a legal opinion.
The 2024 report does not print total hardness as CaCO3. Chloramines 2.1 ppm (2.0–2.1). TTHMs highest LRAA 55.3 ppb (32–80). HAA5 52.5 ppb (14–93). Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
