What Makes Cocoa's Water Unique?
Local geology and source profile
Cocoa, Florida, in Brevard County — a Brevard County city adjacent to Rockledge and Cape Canaveral on the Indian River Lagoon in the Space Coast region — receives its municipal water from the City of Cocoa Water Division, drawing from the Floridan Aquifer through production wells in Brevard County.
The moderately hard 105.5 mg/L hardness and TDS of 249.6 mg/L reflect the east-central Florida Floridan Aquifer supply. The Floridan Aquifer at Brevard County is developed in the Eocene Avon Park Formation (dolomitic limestone) and Eocene Ocala Limestone (high-purity carbonate platform), producing the characteristic moderately hard water of Central Florida groundwater supplies — softer than South Florida Floridan supplies (Naples: 250+ mg/L) due to the thicker Miocene Hawthorn Group confining layer in east-central Florida.
At 105.5 mg/L, Cocoa's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.9 ppt warrants a certified drinking water filter — Cape Canaveral Air Force Station (Brevard County — AFFF, the largest PFAS source in the Cocoa area, adjacent to the Indian River Lagoon), Kennedy Space Center (AFFF), and the Space Coast military-aerospace PFAS complex contribute to Cocoa's readings.
Geology & Source: Cocoa in Brevard County draws from City of Cocoa Water on the Floridan Aquifer (Brevard County, Space Coast Florida) — the Floridan Aquifer is developed in Eocene Avon Park Formation and Eocene Ocala Limestone (high-purity carbonate platform, east-central Florida) — Florida Brevard County Eocene Floridan Aquifer carbonate produces moderately hard water at 105.5 mg/L with TDS 249.6 mg/L in this Brevard County Florida city.
