What Makes Flagami's Water Unique?
Local geology and source profile
Flagami, Florida, a neighborhood in west Miami-Dade County — a predominantly Cuban-American and Latino community west of the Tamiami Trail corridor, one of Miami's major west side neighborhoods, known for its working-class character and proximity to the Florida International University campus — draws its municipal water supply from the Biscayne Aquifer via the Miami-Dade Water and Sewer Department (WASD), applying reverse osmosis (RO) membrane treatment blended with conventionally treated supply. Water hardness in Flagami measures 257.5 mg/L — classified as very hard.
Flagami's very hard supply — harder than Coral Gables (149 mg/L) but softer than Little Haiti (319 mg/L) in the same WASD Biscayne system — reflects the west Miami distribution zone's lower RO treatment blend fraction. The raw Biscayne Aquifer (Miami Limestone — Pleistocene calcareous oolitic limestone, among the most permeable and calcareous aquifers in the United States) carries 350–450+ mg/L raw hardness. Miami-Dade WASD applies a moderate RO blend in the west Miami Flagami zone — lower than the southwestern zones (Coral Gables, Hammocks) — producing the very hard 257.5 mg/L at Flagami household taps.
At 257.5 mg/L, Flagami residents face significant hard water challenges. Scale deposits form rapidly on all fixtures and tile — monthly descaling with citric acid solution is essential maintenance. Miami-Dade WASD consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Biscayne Aquifer with reverse osmosis (RO) blending via the Miami-Dade Water and Sewer Department (WASD) — the west Miami Flagami–Westchester Biscayne Aquifer Miami Limestone (Pleistocene); very hard supply at 257.5 mg/L — reflecting a lower RO blend fraction in the west Miami Flagami distribution zone.
