What Makes Iona's Water Unique?
Local geology and source profile
Iona, Florida, in Lee County — an unincorporated Lee County community adjacent to Cape Coral and Fort Myers on the southwest Florida coast — receives its municipal water from Lee County Utilities, drawing from the Upper Floridan Aquifer (Lee County) through the southwest Florida water treatment system.
The hard 168.5 mg/L hardness and TDS of 447.6 mg/L reflect the southwest Florida Lee County Floridan Aquifer's moderately hard Eocene dolomitic character — harder than the Lake County central Florida supply (Tavares: 125.5 mg/L) but less extreme than the Polk County deep evaporitic zone (Lake Wales: 329.5 mg/L). The Upper Floridan Aquifer at Lee County is developed in Eocene Avon Park Formation (dolomite — primary TDS contributor), Eocene Ocala Limestone (calcareous — primary hardness contributor), and minor Oligocene Suwannee Limestone (slightly calcareous).
At 168.5 mg/L, Iona's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 7.9 ppt warrants a certified reverse osmosis drinking water filter — the Lee County southwest Florida military corridor (Page Field / Fort Myers Airport — AFFF), and the Florida Gulf Coast PFAS background from the Gulf Coast military-industrial complex contribute to Iona's elevated readings.
