What Makes Sebring's Water Unique?
Local geology and source profile
Sebring, Florida, in Highlands County — the Highlands County seat adjacent to Avon Park and Lake Placid on the Lake Wales Ridge in central Florida — receives its water from the City of Sebring Water Department, drawing from the Floridan Aquifer through the central Florida distribution.
The hard 136 mg/L hardness and TDS of 340.8 mg/L reflect the Highlands County supply's hard Floridan Aquifer character — the Eocene Avon Park Formation and Ocala Limestone are calcareous-highly calcareous formations in the central Florida karst platform, and the Floridan Aquifer at Highlands County produces consistently hard water throughout the Lake Wales Ridge zone (compare Avon Park FL: 132/330 in Highlands County comparable; Lake Placid FL: 139/351 in Highlands County comparable; Sebring 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 Lake Wales Ridge sand (insoluble — minimal dilution).
At 136 mg/L with TDS 341, Sebring's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 6.8 ppt warrants a certified drinking water filter. Review the City of Sebring's annual water quality report.
Geology & Source: Sebring in Highlands County draws from the Sebring Water on the Floridan Aquifer (Highlands County, central Florida) — the central Florida plateau 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 136 mg/L with TDS 340.8 mg/L.
