Aventura, Florida
Aventura city water on the opened Miami-Dade Water and Sewer Department 2025 Water Quality Report. The report names the Aventura distribution system on the main-system Stage 2 table. Chloramine residual printed for the main system. Hardness as CaCO3 or labeled grains did not print. This file does not invent one.

Best match for Aventura
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.
Also for the kitchen
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.

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.

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.
Softener vs carbon vs under-sink RO
A sketch for Aventura, tied to this file’s best match. Not a quote.
| Box | What it does | Ballpark (estimate) |
|---|---|---|
| Salt-based softener | Removes hardness. Needs a drain. Illegal in some sewer districts. | About $800–$2,500 for a common residential unit (equipment). Installed jobs run higher. |
| Whole-house carbonThis file’s match | Chlorine or chloramine taste — match the listing. Does not soften. | About $400–$1,800 for a typical tank-and-head kit (equipment). |
| Under-sink reverse osmosisThis file’s match | Kitchen tap. Check NSF/ANSI 58 if PFAS or nitrate is why you are shopping. | About $200–$600 on Amazon search; named under-sink units vary. |
These are ballpark equipment ranges, not installed quotes and not what a dealer will write on a kitchen-table sheet. Prices move. Confirm the sewer rule before you price a brine tank.

Aventura drinking water on this file is MIAMI-DADE WATER AND SEWER DEPARTMENT. The opened 2025 report names the Aventura distribution system as six of the main-system Stage 2 TTHM and HAA5 sample sites. This is leftover Florida Aventura, not leftover South Dade Water Supply, Coral Gables, Doral, or Cutler Bay, which that booklet does not name. 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 opened 2025 report prints a main-system chloramine running annual average of 2.5 ppm (ND–4.0). It does not print hardness as mg/L CaCO3 or labeled grains. This file does not invent one. Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
