What Makes Aventura's Water Unique?
Local geology and source profile
Aventura, Florida, in Miami-Dade County — a major northeast Miami-Dade County coastal community, home of Aventura Mall (one of the largest and highest-grossing shopping malls in the United States — Aventura Mall is a major luxury retail destination), a wealthy and diverse planned community with a large Jewish-American, Latin American, and Russian-American population, and a premier South Florida waterfront community on the Intracoastal Waterway adjacent to Hallandale Beach and North Miami Beach — draws its municipal water supply from the Biscayne Aquifer via the North Miami Beach Water System. Water hardness in Aventura measures 120.5 mg/L — classified as moderately hard.
Aventura's moderate hardness — much softer than neighboring Hallandale Beach (236.5 mg/L) — reflects effective lime softening of the Biscayne Aquifer in the Aventura distribution zone. The Biscayne Aquifer in northeast Miami-Dade County is the same highly calcareous Pleistocene Miami Limestone (raw hardness 200–350 mg/L). North Miami Beach Water System applies effective lime softening to substantially reduce hardness, producing the moderate 120.5 mg/L at Aventura — a good example of how Florida water utility treatment choices dramatically affect delivered hardness.
At 120.5 mg/L, Aventura residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. North Miami Beach Water System consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Biscayne Aquifer (surficial limestone aquifer) via the North Miami Beach Water System (serving Aventura) — the Miami-Dade County northeast Florida Atlantic coastal barrier (Pleistocene Miami Limestone and Fort Thompson Formation — the highly calcareous Biscayne Aquifer; effective lime softening in the Aventura distribution zone); moderately hard supply at 120.5 mg/L — reflecting effective lime softening of the Biscayne Aquifer in the Aventura zone.
