City of Port St. Lucie Utility Systems Department — 2025 Report
| Parameter | What the Report Shows |
|---|---|
| Water Source | Two independent sources blended in distribution: the East Coast Surficial Aquifer (~100 ft, treated at the James E. Anderson lime-softening plant) and the brackish Floridan Aquifer (~1,350 ft, treated by reverse osmosis at the Prineville RO/Lime Softening complex, 11.15 + 22.5 MGD). |
| Treatment Process | Surficial water: lime softening, polymer coagulation, multi-media filtration, chloramine disinfection. Floridan water: reverse osmosis desalination, then pH adjustment and disinfection. A new 10 MGD RO plant (Discovery Water Treatment Facility) is under development, targeted for late-2029 operation. |
| Disinfectant | Chloramines (2025 system-wide level 3.14 ppm; MRDL 4.0 ppm). |
| Hardness | The 2025 Water Quality Report does not publish a numeric hardness figure. Because the James E. Anderson plant specifically operates as a lime-softening facility, hardness reduction is clearly part of the treatment process — but no mg/L or GPG result appears in the CCR. |
| PFAS / Unregulated Contaminants | March 2025 UCMR5 testing at the Prineville plant detected PFOS at 3.3 ppt and PFOA at 1.8 ppt (both below the EPA's 4 ppt MCL), plus trace PFHxS and PFBS. The James E. Anderson plant's testing came back non-detect for all PFAS compounds. No MCL violations were reported. |

Port St. Lucie Homes & Hardness
Port St. Lucie is one of the largest master-planned residential footprints on the Treasure Coast, spanning older sections built out in the 1970s–80s alongside newer developments further west toward I-95. Homes served by the James E. Anderson (lime-softening) side of the system and homes served by the Prineville RO plant can see meaningfully different water character depending on which part of the distribution system reaches that block.
What Homeowners Ask Us Most in Port St. Lucie
Because Port St. Lucie blends two very different treatment processes — lime softening on the surficial side and reverse osmosis on the Floridan side — the two most common questions we hear are which side of the system a given address is on, and whether the small PFOS/PFOA levels detected at the Prineville plant (both below the EPA's 4 ppt limit) warrant additional filtration at home.
Ion-exchange softening
The standard fix for calcium/magnesium hardness — resin swaps hardness minerals for sodium or potassium ions.
Salt-free conditioning
Crystallizes hardness minerals so they don't stick to pipes and fixtures, without adding sodium to your water.
Appliance & plumbing protection
Softening extends the working life of water heaters, dishwashers, and fixtures by preventing scale buildup.
Sized to your test, not a guess
Softener capacity is set from your actual hardness reading and household water usage.
