What Makes Ponte Vedra Beach's Water Unique?
Local geology and source profile
Ponte Vedra Beach, Florida, an unincorporated community in St. Johns County — a premier northeast Florida Atlantic Coast community (Ponte Vedra Beach is one of the most affluent coastal communities in Florida — a premier golf and resort destination home of the PGA TOUR headquarters, TPC Sawgrass (home of The Players Championship — considered golf's 'fifth major' and one of the most prestigious events on the PGA TOUR), and ATP World Tour headquarters (the Association of Tennis Professionals is headquartered in Ponte Vedra Beach), a wealthy and primarily residential community with a significant financial services and healthcare executive population, and a major resort and second-home destination in northeast Florida — draws its municipal water supply from the Upper Floridan Aquifer via the JEA or St. Johns County Utility. Water hardness in Ponte Vedra Beach measures 321 mg/L — classified as extremely hard.
Ponte Vedra Beach's extremely hard supply reflects the northeast Florida Floridan Aquifer's highly calcareous limestone geology with very limited treatment. The Upper Floridan Aquifer at Ponte Vedra Beach–St. Johns County is hosted in: the Eocene Ocala Limestone (highly calcareous marine limestone) and the Eocene Avon Park Formation (highly calcareous dolomite). The St. Johns County–Ponte Vedra distribution applies minimal lime softening, producing the extreme 321 mg/L.
At 321 mg/L, Ponte Vedra Beach residents face severe hard water challenges. Water softeners are essentially a standard fixture. St. Johns County Utility consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Floridan Aquifer System (Upper Floridan) via the St. Johns County Utility or Jacksonville Electric Authority (JEA) — the St. Johns County northeast Florida Atlantic coastal barrier (Eocene Ocala Limestone and Avon Park Formation — the highly calcareous northeast Florida Floridan Aquifer; limited lime softening in the Ponte Vedra Beach zone); extremely hard supply at 321 mg/L — reflecting the Floridan Aquifer with very limited treatment.
