What Makes Merritt Island's Water Unique?
Local geology and source profile
Merritt Island, Florida, an unincorporated community in Brevard County — a major Space Coast community (Merritt Island is a barrier island on Florida's Space Coast, directly adjacent to Kennedy Space Center — the primary NASA launch facility in the United States; virtually the entire north portion of Merritt Island is part of the Merritt Island National Wildlife Refuge, which surrounds Kennedy Space Center), home of Kennedy Space Center (the historic NASA facility from which all Apollo Moon missions, Space Shuttle missions, and many commercial space launches have originated — a defining landmark of Brevard County and the Florida Space Coast), a diverse Brevard County community with a significant aerospace and defense industry professional population, and adjacent to Cocoa Beach and Cape Canaveral — draws its municipal water supply via the Brevard County Water Resources Department. Water hardness in Merritt Island measures 80.5 mg/L — classified as moderately soft.
Merritt Island's soft supply — surprisingly soft given the Floridan Aquifer's typical hardness — reflects effective Brevard County treatment in the Merritt Island zone. The Upper Floridan Aquifer at Merritt Island–Brevard County raw hardness is typically 200–300 mg/L. Brevard County Water applies aggressive reverse osmosis (RO) treatment and lime softening in the Merritt Island zone, dramatically reducing hardness to the soft 80.5 mg/L.
With hardness at 80.5 mg/L, Merritt Island residents enjoy moderately soft water. Brevard County Water Resources consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Floridan Aquifer System (Upper Floridan) with St. Johns River surface blend via the Brevard County Water Resources Department — the Brevard County central Florida Space Coast barrier island (Eocene Avon Park Formation — the calcareous Brevard County Floridan Aquifer; Brevard County effective lime softening and reverse osmosis treatment in the Merritt Island zone); moderately soft supply at 80.5 mg/L — reflecting effective Brevard County treatment.
