Country Club Water Hardness & Quality Report (2026)

Country Club, Florida, an unincorporated community in Miami-Dade County in the northwest Miami–Hialeah area — a predominantly Cuban-American west Miami-Dade residential community in the Country Club area, part of the dense northwest Miami-Dade suburban-urban zone adjacent to Hialeah, Medley, and Miami Lakes — draws its municipal water supply from the Biscayne Aquifer via the Miami-Dade Water and Sewer Department (WASD). Water hardness in Country Club measures 171.5 mg/L — classified as hard.

Country Club's hard supply reflects the northwest Miami-Dade Biscayne Aquifer's highly calcareous geology. The Biscayne Aquifer at the Country Club–Hialeah northwest corridor is hosted in: the Holocene Miami Limestone (highly calcareous oolitic limestone — the surface rock of south Florida, extremely porous); the Pleistocene Fort Thompson Formation (calcareous freshwater–marine alternating limestone); and the Pamlico Sand (calcareous coastal Pleistocene). The northwest Miami-Dade Biscayne Aquifer at the Hialeah–Country Club zone is among the more calcareous sub-basins of the south Florida Biscayne Aquifer, as the limestone here is particularly thick and pure oolitic carbonate terrain, producing the hard 171.5 mg/L.

At 171.5 mg/L, Country Club residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. Miami-Dade WASD consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
