What Makes Oakleaf Plantation's Water Unique?
Local geology and source profile
Oakleaf Plantation, Florida, in Clay County — a large planned community in western Clay County adjacent to Jacksonville (Duval County), one of the largest master-planned residential developments in the Jacksonville metro area — receives its municipal water from the Clay County Utility Authority (CCUA) or JEA (Jacksonville Electric Authority) water service territory, which draws from the Upper Floridan Aquifer through production wells in the Clay County Jacksonville suburban zone.
The moderately hard 141.5 mg/L hardness and TDS of 358.1 mg/L reflect the Floridan Aquifer's Eocene carbonate geology in Clay County. The Floridan Aquifer System in Clay County accesses the Eocene Avon Park Formation (dolomite — primary producing interval), the Ocala Limestone (Eocene chalky limestone), and in some zones the shallower Hawthorn Group sediment. The Clay County-Duval County area's Floridan Aquifer produces moderately hard water consistent throughout the northeast Florida metropolitan corridor — similar to the Orange Park and Middleburg communities in the same supply zone.
At 141.5 mg/L, Oakleaf Plantation's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and bathroom fixtures develop calcium deposits. Quarterly descaling is appropriate. The PFAS level of 7.0 ppt warrants a certified drinking water filter — Naval Air Station Jacksonville (a major naval aviation AFFF user in the Duval-Clay County corridor), the Camp Blanding Joint Training Center (Florida National Guard — a large AFFF user in Clay County), and the broader Jacksonville military aviation complex contribute to Clay County's PFAS readings.
Geology & Source: Oakleaf Plantation in Clay County draws from the JEA (Jacksonville Electric Authority) water system or Clay County Utility Authority treating the Upper Floridan Aquifer — the Floridan Aquifer in Clay County accesses Eocene Avon Park Formation dolomite and Ocala Limestone beneath the St. Johns River Coastal Plain — Eocene dolomite and carbonate aquifer produces moderately hard water at 141.5 mg/L with TDS 358 mg/L in this Clay County Florida community.
