What Makes Kendale Lakes's Water Unique?
Local geology and source profile
Kendale Lakes, Florida, an unincorporated community in southwest Miami-Dade County — a large planned residential community with a major Cuban-American population adjacent to Kendall and Fontainebleau, one of the largest communities in Miami-Dade County — draws its municipal water supply from the Biscayne Aquifer via the Miami-Dade Water and Sewer Department (WASD), applying reverse osmosis (RO) membrane treatment and conventional treatment to the naturally very hard Biscayne Aquifer. Water hardness in Kendale Lakes measures 259 mg/L — classified as very hard.
Kendale Lakes' very hard supply — similar to Fountainebleau (314.5 mg/L) and Margate (271.5 mg/L) in the raw-to-partially-treated range — reflects the southwest Miami-Dade distribution zone's RO blend characteristics. The raw Biscayne Aquifer in southwest Miami-Dade County (Miami Limestone — Pleistocene calcareous oolitic limestone of extraordinary reactivity) carries extremely hard groundwater (350–450+ mg/L). Miami-Dade WASD applies RO treatment to a significant portion of its supply system, but the Kendale Lakes southwest distribution zone appears to receive a partial RO blend, resulting in the 259 mg/L at the household tap.
At 259 mg/L, Kendale Lakes 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 treated with reverse osmosis (RO) blending via the Miami-Dade Water and Sewer Department (WASD) — the southwest Miami-Dade County Biscayne Aquifer Miami Limestone (Pleistocene); very hard supply at 259 mg/L — reflecting a moderate RO blend in the southwest Miami-Dade Kendale Lakes distribution zone.
