Davie Water Hardness & Quality Report (2026)

Davie, Florida, an affluent suburban town in western Broward County, draws its municipal water supply from the Biscayne Aquifer through the Town of Davie Water and Wastewater Department wellfield network in Broward County. Davie's wells tap the Miami Limestone (oolitic calcarenite), Fort Thompson Formation (freshwater and marine limestone), and Anastasia Formation (coquina — shell-fragment calcarenite) of the Biscayne Aquifer at depths of 10–60 feet beneath the flat Broward coastal plain. Water is treated at the Davie Water Treatment Plant before distribution. Water hardness reaches 244.5 mg/L — classified as very hard.

Davie's very hard supply reflects the dense carbonate Biscayne Aquifer formations in western Broward County. The Miami Limestone beneath Davie is a highly reactive, oolitic carbonate rock with extremely high porosity and permeability — the aquifer's dense interconnected void structure allows groundwater to equilibrate thoroughly with calcium carbonate. The Fort Thompson Formation below the Miami Limestone adds dolomitic carbonate dissolution. Western Broward County, being further from the coast, draws groundwater with longer average aquifer residence times than eastern Pompano Beach or Fort Lauderdale, allowing more complete carbonate equilibration — contributing to the very high finished hardness.

At 244.5 mg/L, Davie residents face significant hard water challenges. Scale deposits form rapidly on shower glass, tile, chrome, faucet aerators, and appliance interiors — monthly descaling with commercial citric acid products is essential maintenance. Dishwashers accumulate heavy scale and require rinse-aid plus periodic internal cleaning. Town of Davie Water and Wastewater Department consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
