Daytona Beach Water Hardness & Quality Report (2026)

Daytona Beach, Florida, in Volusia County on the Atlantic Coast — famous for the Daytona 500 and spring break, the 'World's Most Famous Beach' — draws its municipal water supply from the Upper Floridan Aquifer via the City of Daytona Beach Utilities Division, pumping from the Volusia County Floridan Aquifer wellfield network accessing the Eocene Ocala Limestone and Suwannee Limestone formations beneath Volusia County. Water hardness in Daytona Beach reaches 250 mg/L — classified as very hard.

Daytona Beach's very hard supply reflects the Upper Floridan Aquifer's carbonate character in Volusia County. The Ocala Limestone Group (late Eocene — highly porous, chalky limestone with extensive fracture porosity) and the Suwannee Limestone (Oligocene — a secondary carbonate unit in the northeastern Florida Floridan) form the principal producing zones beneath Volusia County. The Floridan Aquifer at the Daytona Beach latitude is slightly less dolomitic than the Avon Park Formation–dominated zones of central and south Florida, but the Ocala and Suwannee Limestones dissolve readily under the active karst circulation of northeast Florida, producing the very hard 250 mg/L supply characteristic of Volusia County's Atlantic Coast communities.

At 250 mg/L, Daytona Beach residents face significant hard water challenges. Scale deposits form rapidly on faucet aerators, showerheads, shower glass, and tile — monthly descaling with citric acid solution is essential maintenance. Dishwashers require rinse-aid. City of Daytona Beach Utilities consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
