What Makes Fountainebleau's Water Unique?
Local geology and source profile
Fountainebleau, Florida, an unincorporated community in west Miami-Dade County — a major Hispanic-American (Cuban-American) community, one of the most densely populated western Miami-Dade neighborhoods adjacent to Doral — draws its municipal water supply from the Biscayne Aquifer via the Miami-Dade Water and Sewer Department (WASD), treating Biscayne Aquifer groundwater for the west Miami-Dade communities. Water hardness in Fountainebleau measures 314.5 mg/L — classified as extremely hard.
Fountainebleau's extreme hardness — one of the highest in the Miami-Dade system — reflects the raw Biscayne Aquifer supply at a zone of the Miami-Dade WASD distribution with minimal RO treatment blending. The raw Biscayne Aquifer in Miami-Dade County — formed in the Miami Limestone (Pleistocene calcareous oolitic limestone) and Fort Lauderdale Limestone (Pleistocene coquina and calcarenite) — is one of the most calcareous and reactive shallow carbonate aquifers in the United States. Miami-Dade WASD applies partial RO treatment to some zones, but the Fountainebleau west Miami-Dade distribution zone appears to receive limited RO softening, resulting in the near-raw Biscayne Aquifer hardness of 314.5 mg/L.
At 314.5 mg/L, Fountainebleau residents face severe hard water challenges. Scale forms rapidly on all fixtures — weekly to daily descaling is necessary. Miami-Dade WASD consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements, but home water softeners are strongly advisable.
Geology & Source: Groundwater from the Biscayne Aquifer treated with reverse osmosis (RO) blending via the Miami-Dade Water and Sewer Department (WASD) — the Miami-Dade County Biscayne Aquifer (Fort Lauderdale Limestone and Miami Limestone, Pleistocene); very hard supply at 314.5 mg/L — an unblended or minimally blended Biscayne Aquifer supply in the west Miami-Dade distribution zone.
