What Makes Miramar's Water Unique?
Local geology and source profile
Miramar, Florida — a rapidly growing city in southern Broward County between Fort Lauderdale and Miami — draws its municipal water supply exclusively from the Biscayne Aquifer through the City of Miramar Utility Services wellfield network in Broward County. The Biscayne Aquifer is Florida's most productive and widely used drinking water aquifer — a shallow, unconfined limestone aquifer that underlies Miami-Dade and Broward Counties and serves as the primary water supply for southeast Florida. Miramar's wells tap the Miami Limestone and Fort Thompson Formation (Pleistocene–Holocene age) at depths typically ranging from 10 to 60 feet. Water is treated at Miramar's water treatment facility before distribution. Water hardness measures 132 mg/L — classified as moderately hard.
Miramar's moderate hardness reflects the Biscayne Aquifer's carbonate character in southern Broward County's inland wellfield zone. The Miami Limestone — a porous, oolitic and skeletal calcarenite — and the underlying Fort Thompson Formation (freshwater and marine limestone) form the Biscayne Aquifer's main productive layers. These Pleistocene carbonate rocks are relatively young but highly porous and reactive, readily dissolving calcium bicarbonate into circulating groundwater. Miramar's wellfields in the southern Broward interior zone experience moderate aquifer residence times, contributing a moderate but not extreme carbonate mineral load. The coastal proximity and active Everglades freshwater recharge keeps hardness lower than some deeper Broward zone supplies.
At 132 mg/L, Miramar residents encounter moderate scale build-up on bathroom fixtures, faucet aerators, and in appliances. Monthly cleaning with citric acid descaler maintains showerheads and faucet aerators in good working order. Dishwashers produce cleaner glassware with rinse-aid, and water heaters benefit from annual inspection for element scale. City of Miramar Utility Services consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Biscayne Aquifer beneath southern Broward County via the City of Miramar Utility Services wellfield — the aquifer here draws from the Miami Limestone and Fort Thompson Formation (Pleistocene age), with some influence from deeper Avon Park Formation in the well network; moderate hardness of 132 mg/L reflects the inland Broward Biscayne zone characteristics.
