What Makes Lighthouse Point's Water Unique?
Local geology and source profile
Lighthouse Point, Florida, in Broward County — a Broward County city adjacent to Pompano Beach and Deerfield Beach on the Atlantic coast of southeast Florida — receives its water from the City of Lighthouse Point Utilities, drawing from the Biscayne Aquifer through the southeast Florida distribution.
The moderately hard 125.5 mg/L hardness and TDS of 308.4 mg/L reflect the Broward County Biscayne Aquifer supply's moderate calcareous character — the Holocene Atlantic Coastal Plain limestone and Pleistocene Miami Limestone contribute calcareous mineral content, with the coastal zone tapping slightly more mineralized aquifer zones than the deeper freshwater lens (compare Pompano Beach FL: 123/301 in Broward County comparable; Deerfield Beach FL: 127/315 in Broward County comparable; Lighthouse Point consistent moderate from the same Broward County Biscayne Aquifer Holocene supply). The Biscayne Aquifer at Broward County — Holocene Atlantic Coastal Plain limestone (slightly calcareous — primary hardness contributor), Pleistocene Miami Limestone (calcareous — secondary contributor), and Holocene coastal plain sediment (insoluble — minimal TDS).
At 125.5 mg/L with TDS 308, Lighthouse Point's water is moderately hard — scale builds in appliances. Semi-annual descaling is appropriate. The PFAS level of 6.5 ppt warrants a certified drinking water filter. Review the City of Lighthouse Point's annual water quality report.
Geology & Source: Lighthouse Point in Broward County draws from the Lighthouse Point Water on the Biscayne Aquifer (Broward County, southeast Florida) — the Broward County aquifer draws from Holocene Atlantic Coastal Plain limestone (slightly calcareous) and Pleistocene Miami Limestone (calcareous) — Florida Broward County Biscayne Aquifer Holocene supply produces moderately hard water at 125.5 mg/L with TDS 308.4 mg/L.
