What Makes Country Walk's Water Unique?
Local geology and source profile
Country Walk, Florida, in Miami-Dade County — an unincorporated Miami-Dade County community adjacent to Homestead and Richmond West in far southwest Miami-Dade — receives its municipal water from Miami-Dade County Water and Sewer, drawing from the Biscayne Aquifer (Miami-Dade County) through the Miami-Dade water treatment plant.
The hard 168.5 mg/L hardness and elevated TDS of 447.6 mg/L reflect the south Miami-Dade Biscayne Aquifer's soluble oolitic limestone character. The Biscayne Aquifer is developed in Pleistocene Miami Limestone (oolitic limestone — very high solubility, among the most porous and soluble carbonate in the USA), Pleistocene Fort Thompson Formation (calcareous freshwater limestone), and Pliocene Tamiami Formation (calcareous). The nearly pure Pleistocene oolitic limestone produces the hard south Miami-Dade supply.
At 168.5 mg/L, Country Walk's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 7.9 ppt warrants a certified reverse osmosis drinking water filter — Homestead Air Reserve Base (Miami-Dade County — AFFF) and the south Florida PFAS complex contribute to Country Walk's elevated readings.
Geology & Source: Country Walk in Miami-Dade County draws from Miami-Dade County Water on the Biscayne Aquifer (Miami-Dade County, south Florida) — the Biscayne Aquifer is developed in Pleistocene Miami Limestone (oolitic limestone — highly soluble) and Pleistocene Fort Thompson Formation (calcareous) — Florida Miami-Dade County Biscayne Aquifer Pleistocene oolitic limestone aquifer produces hard water at 168.5 mg/L with TDS 447.6 mg/L in this Miami-Dade County Florida community.
