What Makes Miami Springs's Water Unique?
Local geology and source profile
Miami Springs, Florida, in Miami-Dade County — a Miami-Dade County city adjacent to Hialeah and the Miami International Airport in the northwest Miami metro — receives its water from the Miami-Dade Water and Sewer Department (WASD), drawing from the Biscayne Aquifer (Miami-Dade County) through the Miami metro distribution.
The moderately hard 93.5 mg/L hardness and TDS of 216.1 mg/L reflect the south Florida Biscayne Aquifer's moderate Miami Limestone calcareous character — consistent with other Miami-Dade WASD communities (Hialeah: ~92 mg/L; Coral Gables: ~94 mg/L). The Biscayne Aquifer at Miami-Dade County is developed in Pleistocene Miami Limestone (calcareous, oolitic — primary hardness contributor), Pleistocene Fort Thompson Formation (calcareous, fossiliferous — secondary contributor), and Holocene coastal carbonate sediment. The Pleistocene oolitic Miami Limestone produces the moderately hard south Florida Biscayne supply.
At 93.5 mg/L, Miami Springs' water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.5 ppt warrants a certified drinking water filter — Miami International Airport (Miami-Dade County — AFFF, directly adjacent to Miami Springs) and Homestead Air Reserve Base (Miami-Dade County — AFFF) contribute to Miami Springs' readings.
