What Makes Olympia Heights's Water Unique?
Local geology and source profile
Olympia Heights, Florida, in Miami-Dade County — a Miami-Dade County community adjacent to Westchester and Coral Terrace in the west Miami metro — receives its water from the Miami-Dade Water and Sewer Department, drawing from the Biscayne Aquifer (Miami-Dade County) through the south Florida distribution.
The moderately hard 111.5 mg/L hardness and TDS of 266.8 mg/L reflect the west Miami-Dade County Biscayne Aquifer supply's moderate calcareous character — softer than the south Miami-Dade communities (Naranja: 230.5 mg/L; Palmetto Estates: 178.5 mg/L) due to the west Miami urban position further from the coastal saltwater intrusion gradient, with the Biscayne Aquifer at this location delivering somewhat less dissolved carbonate. The Biscayne Aquifer at Miami-Dade County — Pleistocene Miami Limestone (calcareous — primary hardness contributor), Pleistocene Fort Thompson Formation (calcareous — secondary contributor), and Quaternary urban recharge (dilutant — minor).
At 111.5 mg/L, Olympia Heights' water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 6.1 ppt warrants a certified drinking water filter — Homestead Air Reserve Base (Miami-Dade County — AFFF) and the west Miami industrial corridor contribute to Olympia Heights' readings.
Geology & Source: Olympia Heights in Miami-Dade County draws from the Miami-Dade Water and Sewer Department on Biscayne Aquifer (Miami-Dade County, south Florida) — the Biscayne Aquifer at Miami-Dade County is developed in Pleistocene Miami Limestone (calcareous) and Pleistocene Fort Thompson Formation (calcareous) — Florida Miami-Dade County Biscayne Aquifer Pleistocene calcareous aquifer produces moderately hard water at 111.5 mg/L with TDS 266.8 mg/L.
