What Makes Tamarac's Water Unique?
Local geology and source profile
Tamarac, Florida, in northwest Broward County — a planned community developed in the early 1960s as a retirement community and now one of Broward County's most diverse cities — draws its municipal water supply from the Biscayne Aquifer (Broward County Surficial Aquifer) via the City of Tamarac Utilities Water Division, treating Biscayne Aquifer water with reverse osmosis (RO) membrane treatment to reduce the naturally very hard groundwater hardness. Water hardness in Tamarac measures 113 mg/L — classified as moderately hard, reflecting the blended RO-treated and non-RO supply.
Tamarac's moderate hardness — far below the natural Biscayne Aquifer hardness (typically 300–500 mg/L in Broward County) — reflects the City of Tamarac's reverse osmosis treatment program. The raw Biscayne Aquifer beneath Tamarac in northwest Broward County is formed in the Fort Lauderdale Formation and Miami Limestone (Pleistocene coral reef and oolitic calcareous limestone — one of the most reactive calcareous formations in Florida). The raw Biscayne water in Broward County reaches 300–500 mg/L naturally. Tamarac's RO plant treats a fraction of the supply, blending the RO permeate (essentially zero hardness) with some bypass raw water to achieve the 113 mg/L finished supply — a common RO blending strategy in South Florida utilities.
At 113 mg/L, Tamarac residents enjoy moderately hard water — noticeably improved compared to non-RO Broward County communities. City of Tamarac Utilities Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Biscayne Aquifer treated with reverse osmosis (RO) via the City of Tamarac Utilities Water Division — the Broward County Surficial Biscayne Aquifer (Fort Lauderdale Formation and Miami Limestone); moderately hard supply at 113 mg/L — substantially softened by RO treatment from the naturally very hard (~300+ mg/L) Biscayne Aquifer.
