What Makes Sarasota's Water Unique?
Local geology and source profile
Sarasota, Florida, the Sarasota County seat on Sarasota Bay on the Gulf of Mexico — a major Gulf Coast arts and culture hub known for the Ringling Museum, the Sarasota Ballet, Marie Selby Botanical Gardens, and Siesta Key beach — draws its municipal water supply from the Floridan Aquifer System and the Peace River (via the Manasota Regional Water Supply Authority) via the City of Sarasota Water Resources Division. Water hardness in Sarasota measures 110.5 mg/L — classified as moderately hard.
Sarasota's moderate hardness — softer than many central and south Florida communities — reflects the effective treatment and blending of the Floridan Aquifer and Peace River supplies. The raw Floridan Aquifer in Sarasota County (Oligocene Suwannee Limestone and Eocene Ocala Limestone — highly reactive calcareous carbonates) carries very hard groundwater (250–400+ mg/L). The Peace River surface water supply (draining the Polk County phosphate mining region and the Florida Highlands — a calcareous but moderately hard surface water) provides a softer blending component. Sarasota Water Resources Division applies conventional lime-soda softening treatment to the blend, reducing the combined supply to the moderate 110.5 mg/L.
At 110.5 mg/L, Sarasota residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. City of Sarasota Water Resources Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
