What Makes Doral's Water Unique?
Local geology and source profile
Doral, Florida — the largest municipality in northwest Miami-Dade County, an edge city adjacent to MIA Airport and home of the Trump National Doral resort — draws its municipal water supply from the Biscayne Aquifer via the Miami-Dade Water and Sewer Department (MDWASD), pumping from the Miami-Dade northwest wellfield network accessing the Pleistocene Miami Limestone and Fort Thompson Formation of the Biscayne Aquifer near the Everglades boundary. Doral is one of Miami-Dade's newest major municipalities (incorporated 2003). Water hardness in Doral reaches 310.5 mg/L — classified as very hard.
Doral's very hard supply reflects the northwest Miami-Dade Biscayne Aquifer's character near the Everglades boundary. The Miami Limestone (Pleistocene oolitic limestone — highly porous and reactive) in northwest Dade near the Everglades edge is among the most active dissolution zones — the Everglades freshwater head from the west drives active through-flow of water through the Miami Limestone, maintaining very high dissolved calcium concentrations from the continuous oolite dissolution. The northwest Dade wellfields (closest to the Everglades Water Conservation Areas) tap some of the most chemically reactive Biscayne Aquifer sections. MDWASD treatment reduces raw hardness somewhat, but finished hardness in Doral's distribution zone remains extremely high.
At 310.5 mg/L, Doral residents face severe hard water challenges. Scale deposits form rapidly on all fixtures and surfaces — regular descaling with commercial citric acid products is essential. Water heaters need semi-annual inspection and descaling. MDWASD consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Biscayne Aquifer via the Miami-Dade Water and Sewer Department (MDWASD) — the Pleistocene Miami Limestone and Fort Thompson Formation of the northwest Miami-Dade County Biscayne Aquifer; very hard supply at 310.5 mg/L — among the hardest in the Miami-Dade distribution system, reflecting the northwest Dade Biscayne Aquifer character near the Everglades boundary.
