Leesburg Water Hardness & Quality Report (2026)

Leesburg, Florida, in Lake County — a central Florida city in the heart of Lake County (named for its more than 1,000 lakes), known as the gateway to the Chain of Lakes and the western Lake County citrus and recreational corridor — receives its municipal water from Leesburg Utilities, which draws from the Upper Floridan Aquifer through production wells in the Lake County karst landscape. Leesburg's setting in the most intensely lake-dotted county in the continental United States creates a unique groundwater environment.

The moderately hard 106.5 mg/L hardness and TDS of 252.5 mg/L are significantly softer than typical deep Floridan production in central Florida (Venice 278.5 mg/L, Greater Northdale 277.5 mg/L), reflecting the Lake County Floridan Aquifer's unusual degree of active recharge dilution. Lake County's extensive karst lakes — including the Winter Garden-Leesburg Chain of Lakes system — provide direct recharge pathways into the shallow Floridan Aquifer, continuously diluting the carbonate groundwater with relatively soft lake surface water. This active recharge cycle prevents the extreme mineral concentration seen in more confined Floridan zones farther south, where groundwater has had prolonged contact with the deep Eocene Avon Park dolomites without dilution. The result is a moderately hard Floridan supply substantially fresher than Florida coastal zone equivalents.

At 106.5 mg/L, Leesburg's water is moderately hard for a Florida city — a welcome departure from the very hard Floridan norms. Scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling of heating appliances is appropriate. The PFAS level of 5.9 ppt warrants a certified drinking water filter — Lake County's suburban development, the greater Orlando metropolitan area's PFAS legacy, and the Leesburg Regional Airport flight training operations contribute to the central Lake County PFAS background.
