What Makes Mount Dora's Water Unique?
Local geology and source profile
Mount Dora, Florida, in Lake County — a Lake County city adjacent to Tavares and Eustis on Lake Dora in central Florida — receives its water from the City of Mount Dora Utilities, drawing from the Floridan Aquifer (Lake County) through the central Florida distribution.
The hard 179 mg/L hardness and TDS of 484.1 mg/L reflect the central Florida Lake County Floridan Aquifer supply's hard calcareous character — driven by the Eocene Ocala and Avon Park Limestone platform that produces significant calcareous dissolution across central Florida (compare Destin FL: 282 mg/L on deeper Panhandle supply; Forest City FL: 210 mg/L; Homosassa Springs FL: similar Floridan supply), consistent with the well-documented Lake County central Florida karst zone. The Floridan Aquifer at Lake County — Eocene Ocala Limestone (highly calcareous — primary hardness contributor), Eocene Avon Park Limestone (highly calcareous — secondary contributor), and Quaternary surficial sand (insoluble — minor dilutant).
At 179 mg/L with TDS 484, Mount Dora's water is hard. A water softener is recommended to prevent scale buildup in appliances. A reverse osmosis system is advisable for drinking water. The PFAS level of 8.2 ppt warrants a certified drinking water filter — the Lake County central Florida industrial corridor contribute to Mount Dora's elevated readings.
Geology & Source: Mount Dora in Lake County draws from the City of Mount Dora Utilities on the Floridan Aquifer (Lake County, central Florida) — the Floridan Aquifer at Lake County is developed in Eocene Ocala Limestone (highly calcareous) and Eocene Avon Park Limestone (highly calcareous) — Florida Lake County Floridan Aquifer Eocene calcareous aquifer produces hard water at 179 mg/L with TDS 484.1 mg/L.
