What Makes West Perrine's Water Unique?
Local geology and source profile
West Perrine, Florida, in Miami-Dade County — a Miami-Dade County unincorporated community adjacent to Perrine and Cutler Bay in south Miami-Dade — receives its water from the Miami-Dade Water and Sewer Department (MDWASD), drawing from the Biscayne Aquifer through the south Florida distribution.
The hard 173.5 mg/L hardness and TDS of 464.9 mg/L reflect the Miami-Dade County south Biscayne supply's hard calcareous character — the Holocene Biscayne Aquifer limestone and Pleistocene Miami Limestone are calcareous formations in the south Florida karst; West Perrine's higher hardness relative to north Miami-Dade communities reflects the deeper aquifer penetration and higher mineral saturation in the south county supply zone (compare Perrine FL: 169/453 in Miami-Dade County comparable; Cutler Bay FL: 177/476 in Miami-Dade County comparable; West Perrine consistent hard from the same Miami-Dade County Biscayne Aquifer Holocene calcareous supply). The South Miami-Dade Biscayne Aquifer — Holocene Biscayne Aquifer limestone (calcareous — primary hardness contributor), Pleistocene Miami Limestone (calcareous — secondary contributor), and Quaternary South Florida Coastal plain (insoluble — minimal dilution).
At 173.5 mg/L with TDS 465, West Perrine's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 8.0 ppt warrants a certified drinking water filter. Review MDWASD's annual water quality report.
Geology & Source: West Perrine in Miami-Dade County draws from the MDWASD on the Biscayne Aquifer (Miami-Dade County, south Florida) — the Miami-Dade County aquifer draws from Holocene Biscayne Aquifer limestone (calcareous) and Pleistocene Miami Limestone (calcareous) — Florida Miami-Dade County Biscayne Aquifer Holocene calcareous supply produces hard water at 173.5 mg/L with TDS 464.9 mg/L.
