What Makes Eustis's Water Unique?
Local geology and source profile
Eustis, Florida, in Lake County — a historic Lake County city on Lake Eustis in the Central Florida lake district, part of the Leesburg-Tavares-Eustis triangle at the heart of Florida's lake highlands region — receives its municipal water from the City of Eustis Water Department, which draws from the Upper Floridan Aquifer through production wells in central Lake County.
The moderately hard 164.5 mg/L hardness and elevated TDS of 434 mg/L reflect the Floridan Aquifer's Eocene dolomite character in central Lake County. The Floridan Aquifer System in Lake County accesses the Eocene Avon Park Formation (dolomite — primary producing interval) and in deeper wells the Oldsmar Formation (dolomite). The elevated TDS (434 mg/L) in the Lake County supply reflects the deep Floridan Aquifer's greater evaporite mineral contact (gypsum/anhydrite zones in the Eocene carbonate) relative to the shallower Panhandle Floridan, consistent with the central Florida Floridan character throughout the lake district.
At 164.5 mg/L, Eustis'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 7.7 ppt warrants a certified drinking water filter — the Central Florida industrial and development corridor, the Orlando military-industrial complex (Naval Training Center Orlando legacy), and the Lake County agricultural-industrial PFAS background contribute to Eustis's elevated readings.
Geology & Source: Eustis in Lake County draws from the City of Eustis Water on the Upper Floridan Aquifer — the Floridan Aquifer in Lake County accesses Eocene Avon Park Formation dolomite and the deeper Oldsmar Formation beneath the central Florida lake district — Eocene dolomite aquifer produces moderately hard water at 164.5 mg/L with elevated TDS 434 mg/L in this Lake County Florida city.
