What Makes Miami Lakes's Water Unique?
Local geology and source profile
Miami Lakes, Florida, in Miami-Dade County — a major northwest Miami-Dade suburban community (Miami Lakes is one of the earliest and most successful planned communities in South Florida — developed beginning in the 1960s by the Graham family (the family that includes former Florida Governor and US Senator Bob Graham) as a carefully planned suburban town with lakes, parks, and mixed-use development; Miami Lakes was one of the pioneering examples of master-planned suburban community development in Florida), a diverse Miami-Dade community with a significant Cuban-American, Colombian-American, Nicaraguan-American, and Latin American professional population (Miami Lakes is in the northwest Miami-Dade Latin American-American suburban corridor), home of a significant corporate campus cluster (Miami Lakes has attracted numerous Fortune 500 regional offices and medical device companies), and one of Miami-Dade's most desirable suburban communities — draws its municipal water supply from the Biscayne Aquifer via the MDWASD. Water hardness in Miami Lakes measures 90 mg/L — classified as moderately soft.
Miami Lakes's moderate softness — much softer than typical Biscayne Aquifer values (~200+ mg/L) — reflects MDWASD's effective reverse osmosis treatment. The MDWASD applies advanced reverse osmosis treatment to Biscayne Aquifer water at the Northwest well field, producing the moderately soft 90 mg/L for the northwest Miami-Dade corridor.
With hardness at 90 mg/L, Miami Lakes residents enjoy moderately soft water. MDWASD consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Biscayne Aquifer (Miami Limestone) via the Miami-Dade Water and Sewer Department (MDWASD) — the Miami-Dade County northwest suburban Miami Lakes corridor (Pleistocene calcareous Miami Limestone — the extremely calcareous southeast Florida Biscayne Aquifer; MDWASD northwest Miami-Dade treatment to Miami Lakes zone with some softening); moderately soft supply at 90 mg/L in Miami-Dade County.
