A small city with its own water plant
Most of Miami-Dade buys water from the county. Florida City is one of the exceptions: it operates its own public water system (PWS 4130255), with a Water & Sewer Department at 461 NW 6 Avenue and a Water Plant Supervisor on staff. The city's annual report describes the whole process in one line: the source is groundwater from the Biscayne Aquifer, and the water is disinfected by chlorination.
That short treatment description matters for anyone shopping for a filter. It means the disinfectant reaching your tap is chlorine, and the report does not describe a softening step. Hardness and mineral content are therefore questions to answer with a test at your own tap rather than assumptions borrowed from a neighboring utility.
What the 2025 report shows
| Item | Florida City 2025 report |
|---|---|
| Source | Biscayne Aquifer groundwater |
| Disinfection | Chlorination; chlorine running annual average 1.43 ppm (range 1 to 1.61), limit 4.0 |
| Fluoride | 0.16 ppm |
| Sodium | 24 ppm |
| Nitrate (as nitrogen) | 1.2 ppm, limit 10 |
| TTHM / HAA5 | 38.53 ppb / 16.53 ppb, limits 80 / 60 |
| Copper at the tap | 90th percentile 1.1 ppm, action level 1.3; 2 sites above it |
| Lead at the tap | 90th percentile 1 ppb; no sites above the action level |
The Florida Department of Environmental Protection's 2025 source water assessment found four potential sources of contamination near the city's wells, all rated low susceptibility. Results are on the FDEP Source Water Assessment and Protection Program site.
Chlorine, not chloramine: why it changes the shopping list
Free chlorine is the easier of the two disinfectants for a home carbon filter to handle. Chloramine, used by the county's main system, generally needs catalytic carbon and more contact time. For a Florida City home on city water, that often means a well-sized whole-home city water system is mainly a comfort upgrade for showers and laundry, while an under-sink alkaline RO handles drinking and cooking water.
If you moved here from elsewhere in the county and the water tastes or smells different, you are not imagining it. Different utilities, different chemistry.
Who serves your address
- Inside city limits: City of Florida City Water & Sewer.
- Unincorporated areas south of SW 264 Street: Miami-Dade WASD says its South Dade Water Supply System, five smaller Biscayne Aquifer plants on their own distribution network, serves residents there.
- Rural and farm lots: some properties rely on private wells. Miami-Dade publishes an open-data list of properties potentially served by septic or wells. See well water in Florida City.
Check the name on your water bill if you are unsure.
What fits a Florida City home
- Chlorine taste and smell at every tap: whole-home city water system.
- Better drinking water only: compact alkaline RO under the kitchen sink.
- Spots and scale: confirm hardness first; see hard water spots and water softeners.
- Private well: a well water system built from the well's test.
- Restaurants, motels and shops: commercial softening or drinking-water systems sized after testing.

Reading the report like a homeowner
A Consumer Confidence Report can look like a wall of abbreviations. Three columns do most of the work. Level Detected is the number that counts for compliance. MCL or MRDL is the legal limit. Likely Source tells you whether something comes from nature, from plumbing, or from treatment itself.
In Florida City's 2025 table, the radioactive results (radium, uranium, alpha emitters) are listed as erosion of natural deposits, typical of groundwater. The disinfection byproducts TTHM and HAA5 come from chlorination. Lead and copper come from household plumbing, which is why they are sampled at homes rather than at the plant. Reading it this way tells you which questions a home system can answer and which are about your pipes.
Restaurants, motels, laundromats, car washes and offices along the US 1 corridor have different priorities from homes: protecting ice machines, coffee equipment, boilers and dishwashers from scale, and keeping water taste consistent for customers. Living Water installs ion-exchange softening plants and drinking-water systems for businesses, sized after the same free test. Jorge can test at the equipment that matters most to you, such as the ice machine supply line.
Call, text or WhatsApp Jorge at (305) 793-5974. He tests at your tap, explains each number in plain words, and recommends a system only if it fits. Living Water offers financing through its financing partners; you apply with a credit application, and a co-applicant can apply with you.
For questions about the city's water itself, the 2025 report lists the Utilities office at 305-248-6855, and that number also handles requests for the report in Spanish.
