What Makes Port Salerno's Water Unique?
Local geology and source profile
Port Salerno, Florida, in Martin County — a Martin County unincorporated community adjacent to Stuart and Hobe Sound on the St. Lucie River in southeast Florida — receives its water from the Martin County Utilities, drawing from the Surficial and Floridan Aquifer through the southeast Florida distribution.
The soft 73 mg/L hardness and TDS of 161.6 mg/L reflect the Martin County supply's soft southeast Florida coastal character — the Eocene Avon Park Formation and Oligocene Suwannee Limestone are calcareous formations in the southeast Florida karst; the Martin County coastal aquifer produces softer water than the deeper Floridan zones at the south-central Florida interior (compare Stuart FL: 70/155 in Martin County comparable; Hobe Sound FL: 75/168 in Martin County comparable; Port Salerno consistent soft from the same Martin County Floridan Aquifer Eocene calcareous supply). The Surficial/Floridan Aquifer at Martin County — Eocene Avon Park Formation (calcareous — primary hardness contributor), Oligocene Suwannee Limestone (calcareous — secondary contributor), and Quaternary southeast Florida coastal sand (insoluble — dilution).
At 73 mg/L with TDS 162, Port Salerno's water is soft — minimal scale buildup. Annual descaling as preventative maintenance is sufficient. The PFAS level of 4.9 ppt is moderate — a certified drinking water filter provides added protection. Review the Martin County Utilities' annual water quality report.
