Hollywood Water Hardness & Quality Report (2026)

Hollywood, Florida (not to be confused with the Los Angeles neighbourhood) draws its municipal water supply from the City of Hollywood Water Treatment Division, sourcing groundwater from the Biscayne Aquifer through a wellfield network in Broward County positioned in the coastal and near-coastal zone of south Broward. The Biscayne Aquifer — Florida's primary drinking water resource for southeast coastal communities — is an exceptionally productive unconfined limestone aquifer serving Hollywood and its neighbouring cities. Water is treated at the Hollywood Water Treatment Plant before distribution. Water hardness in Hollywood, Florida measures 80 mg/L — classified as moderately soft, notably lower than other Broward County Biscayne Aquifer cities such as Fort Lauderdale (301.5 mg/L) or Pembroke Pines (228.5 mg/L).

Hollywood's surprisingly soft reading for a Biscayne Aquifer city reflects the hydrogeological characteristics of the coastal Biscayne zone in south Broward County. Hollywood's wellfields are positioned near the Atlantic coast and the Intracoastal Waterway, where the shallow Biscayne Aquifer is recharged by high volumes of relatively low-TDS Atlantic-influenced rainfall and shallow Everglades freshwater moving eastward through the aquifer. This coastal and near-coastal zone experiences more frequent aquifer turnover and shorter groundwater residence times than inland Broward wellfields, limiting the time available for Miami Limestone carbonate dissolution and producing a significantly softer supply than inland communities drawing from deeper, longer-residence zones.

With hardness at 80 mg/L, Hollywood, Florida residents enjoy one of the softer municipal water supplies in Broward County. Scale accumulation on faucets, showerheads, and in appliances is light — occasional cleaning is sufficient. Dishwashers produce largely clean glassware, and hot water systems remain relatively free of scale throughout their operational life. Hollywood Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
