What Makes Santa Rosa Beach's Water Unique?
Local geology and source profile
Santa Rosa Beach, Florida, in Walton County — a major northwest Florida Emerald Coast resort community (Santa Rosa Beach is in the heart of the Florida Panhandle's Emerald Coast — one of the most sought-after beach resort destinations in the southeastern United States; the 30A corridor in South Walton County includes some of the most beautiful white sand beaches in the country, with communities like Seaside, Rosemary Beach, and WaterColor drawing wealthy second-home owners and vacationers from across the South and Midwest), a diverse Walton County community with a significant year-round affluent residential and vacation rental population, adjacent to the Point Washington State Forest and Choctawhatchee Bay, and home of numerous high-end beach resort communities — draws its municipal water supply from the Floridan Aquifer via the South Walton County Utility. Water hardness in Santa Rosa Beach measures 107 mg/L — classified as moderately hard.
Santa Rosa Beach's moderate hardness reflects the northwest Florida Walton County Floridan Aquifer's calcareous-moderate limestone geology. The Floridan Aquifer at Santa Rosa Beach–Walton County draws from the Eocene–Oligocene Ocala and Suwannee Limestone (calcareous-moderate marine carbonate, somewhat less calcareous than the south Florida Biscayne zone). Treatment produces the moderate 107 mg/L.
With hardness at 107 mg/L, Santa Rosa Beach residents encounter moderate scale accumulation. Monthly cleaning is recommended. South Walton Utility consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Floridan Aquifer (sand and gravel zone) via the South Walton County Utility or local water authority — the Walton County northwest Florida Emerald Coast panhandle corridor (Eocene–Oligocene calcareous-moderate Ocala and Suwannee Limestone — the calcareous-moderate northwest Florida Floridan Aquifer; Walton County panhandle aquifer supply with treatment); moderately hard supply at 107 mg/L in Walton County.
