What Makes Miami Shores's Water Unique?
Local geology and source profile
Miami Shores, Florida, in Miami-Dade County — a Miami-Dade County village adjacent to North Miami and Miami on the Atlantic coastal ridge in southeast Florida — receives its water from the Miami-Dade Water and Sewer Department (MDWASD), drawing from the Biscayne Aquifer through the southeast Florida distribution.
The moderately hard 92.5 mg/L hardness and TDS of 213.2 mg/L reflect the Miami-Dade County Biscayne supply's moderate calcareous character — the Holocene Biscayne Aquifer limestone and Pleistocene Miami Limestone are slightly-to-moderately calcareous formations in the southeast Florida coastal karst, and the Miami Shores area taps slightly more mineralized aquifer zones than the westernmost Miami-Dade communities (compare North Miami FL: 90/208 in Miami-Dade County comparable; Miami FL: 94/218 in Miami-Dade County comparable; Miami Shores consistent moderate from the same Miami-Dade County Biscayne Aquifer calcareous supply). The Biscayne Aquifer at Miami-Dade County — Holocene Biscayne Aquifer limestone (slightly calcareous — primary hardness contributor), Pleistocene Miami Limestone (calcareous — secondary contributor), and Holocene Atlantic Coastal plain sediment (insoluble — minimal dilution).
At 92.5 mg/L with TDS 213, Miami Shores' water is moderately hard — mild scale buildup. Semi-annual descaling is appropriate. The PFAS level of 5.5 ppt warrants a certified drinking water filter. Review MDWASD's annual water quality report.
Geology & Source: Miami Shores in Miami-Dade County draws from the MDWASD on the Biscayne Aquifer (Miami-Dade County, southeast Florida) — the Miami-Dade County aquifer draws from Holocene Biscayne Aquifer limestone (slightly calcareous) and Pleistocene Miami Limestone (calcareous) — Florida Miami-Dade County Biscayne Aquifer calcareous supply produces moderately hard water at 92.5 mg/L with TDS 213.2 mg/L.
