What Makes Kendall West's Water Unique?
Local geology and source profile
Kendall West, Florida, an unincorporated community in Miami-Dade County — a major west Miami-Dade County suburban community (Kendall West is in the far western edge of Miami-Dade County's suburban corridor, adjacent to the Everglades boundary), a diverse Miami-Dade County community with a significant Cuban-American, Colombian-American, Venezuelan-American, and Nicaraguan-American population, part of the broader Kendall–Sweetwater suburban corridor of southwest Miami-Dade County, and a rapidly growing western Miami-Dade community at the urban–rural interface — draws its municipal water supply from the Biscayne Aquifer via the Miami-Dade WASD. Water hardness in Kendall West measures 328.5 mg/L — classified as extremely hard.
Kendall West's extremely hard supply reflects the west Miami-Dade County Biscayne Aquifer's highly calcareous limestone geology. The Biscayne Aquifer in the Kendall West–far west Miami-Dade area draws from the Pleistocene Miami Limestone (highly calcareous oolitic limestone — approximately 90% CaCO₃) and the Fort Thompson Formation (calcareous freshwater marl — the Biscayne Aquifer source in the western Everglades fringe zone). Miami-Dade WASD applies very limited lime softening in the far west Kendall corridor, producing the extremely hard 328.5 mg/L.
At 328.5 mg/L, Kendall West residents face severe hard water challenges. Water softeners are essentially a necessity. Miami-Dade WASD 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 Miami-Dade Water and Sewer Department (WASD) — the Miami-Dade County southwest Florida suburban Kendall corridor (Pleistocene Miami Limestone and Fort Thompson Formation — the highly calcareous west Miami-Dade Biscayne Aquifer; limited lime softening in the Kendall West suburban zone); extremely hard supply at 328.5 mg/L — reflecting the Biscayne Aquifer with very limited treatment.
