West Hollywood Water Hardness & Quality Report (2026)

West Hollywood (Dania Beach–Hollywood area), Florida, in south Broward County — a Hollywood, Florida neighborhood adjacent to the City of Hollywood in the Fort Lauderdale–Hollywood metro area — draws its municipal water supply from the Biscayne Aquifer via the City of Hollywood Utilities Water Division, applying reverse osmosis (RO) membrane treatment and conventional treatment to the naturally very hard Broward County coastal aquifer. Water hardness in West Hollywood–Hollywood, FL measures 165 mg/L — classified as hard, reflecting a partial RO softening blend.

West Hollywood's hard supply — above some other RO-treated South Florida communities (Tamarac: 113 mg/L, Boynton Beach: 87 mg/L) but far below the raw Biscayne Aquifer (300–500 mg/L) — reflects the City of Hollywood's particular RO blend ratio. The raw Biscayne Aquifer in south Broward County is very hard from the Fort Lauderdale Limestone and Anastasia Formation coquina (highly reactive Pleistocene calcareous formations). The Hollywood Utilities RO plant treats a fraction of the supply — blending the zero-hardness RO permeate with conventional-treated bypass supply to achieve approximately 165 mg/L, a moderate hardness consistent with the south Broward County distribution zone's RO program parameters.

At 165 mg/L, West Hollywood–Hollywood, FL residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. City of Hollywood Utilities Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
