What Makes Avon Park's Water Unique?
Local geology and source profile
Avon Park, Florida, in Highlands County — the Highlands County seat adjacent to Sebring and Lake Placid in the south-central Florida lake highlands — receives its water from the City of Avon Park Water Department, drawing from the Floridan Aquifer through the south-central Florida distribution.
The hard 122 mg/L hardness and TDS of 297.8 mg/L reflect the Highlands County supply's hard Floridan Aquifer character — the Eocene Avon Park Formation and Eocene Ocala Limestone are calcareous formations in the south-central Florida karst platform; the Floridan Aquifer at Highlands County produces hard, moderate-TDS water throughout the Lake Highlands area (compare Sebring FL: 118/288 in Highlands County comparable; Lake Placid FL: 125/308 in Highlands County comparable; Avon Park consistent hard from the same Highlands County Floridan Aquifer Eocene calcareous supply). The Floridan Aquifer at Highlands County — Eocene Avon Park Formation (calcareous — primary hardness contributor), Eocene Ocala Limestone (highly calcareous — secondary contributor), and Quaternary Central Florida sand (insoluble — minimal dilution).
At 122 mg/L with TDS 298, Avon Park's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 6.4 ppt warrants a certified drinking water filter. Review the City of Avon Park's annual water quality report.
Geology & Source: Avon Park in Highlands County draws from the Avon Park Water on the Floridan Aquifer (Highlands County, south-central Florida) — the south-central Florida karst at Highlands County draws from Eocene Avon Park Formation (calcareous) and Eocene Ocala Limestone (highly calcareous) — Florida Highlands County Floridan Aquifer Eocene calcareous supply produces hard water at 122 mg/L with TDS 297.8 mg/L.
