What Makes Westwood Lake's Water Unique?
Local geology and source profile
Westwood Lake, Florida, in Miami-Dade County — a Miami-Dade County unincorporated community adjacent to Miami and Doral in southeast Florida — receives its water from Miami-Dade Water and Sewer, drawing from the Biscayne Aquifer through the southeast Florida distribution.
The hard 187.5 mg/L hardness and elevated TDS of 514.2 mg/L reflect the Miami-Dade County Biscayne Aquifer supply's hard calcareous character — the Pleistocene Miami Limestone and Fort Thompson Formation are both highly calcareous Quaternary carbonate formations, and the shallow unconfined aquifer picks up marine chloride and sulfate minerals near the coast (compare Miami FL: 185/508 in Miami-Dade County comparable; Doral FL: 190/520 in Miami-Dade County comparable; Westwood Lake consistent hard from the same Miami-Dade County Biscayne Aquifer Pleistocene calcareous supply). The Biscayne Aquifer at Miami-Dade County — Pleistocene Miami Limestone (highly calcareous — primary hardness contributor), Pleistocene Fort Thompson Formation (calcareous — secondary contributor), and Holocene Biscayne Bay alluvium (calcareous — TDS contributor).
At 187.5 mg/L with TDS 514, Westwood Lake's water is hard with elevated dissolved solids — scale builds in appliances over months. Quarterly descaling is appropriate. The PFAS level of 8.5 ppt is elevated — a certified drinking water filter with PFAS removal is strongly recommended — the Miami-Dade County southeast Florida military and industrial sources contribute to Westwood Lake's elevated PFAS readings.
Geology & Source: Westwood Lake in Miami-Dade County draws from Miami-Dade Water and Sewer on the Biscayne Aquifer (Miami-Dade County, southeast Florida) — the Biscayne Aquifer is developed in Pleistocene Miami Limestone (highly calcareous) and Pleistocene Fort Thompson Formation (calcareous) — Florida Miami-Dade County Biscayne Aquifer Pleistocene calcareous supply produces hard water at 187.5 mg/L with TDS 514.2 mg/L.
