What Makes Glenvar Heights's Water Unique?
Local geology and source profile
Glenvar Heights, Florida, in Miami-Dade County — an unincorporated Miami-Dade County community adjacent to Westchester and Coral Terrace in the western Miami metro — receives its municipal water from Miami-Dade Water and Sewer Department (WASD), drawing from the Biscayne Aquifer through the County's wellfields (Northwest Wellfield, West Wellfield) in Miami-Dade County.
The moderately hard 131.5 mg/L hardness and TDS of 326.8 mg/L reflect the Miami-Dade Biscayne Aquifer's porous limestone character. The Biscayne Aquifer at Miami-Dade is developed in the Quaternary Miami Limestone (the surficial aquifer unit — highly porous oolitic calcarenite), Pleistocene Key Largo Limestone (porous reef limestone), and Fort Thompson Formation (calcareous freshwater marl). The highly porous calcareous limestone matrices readily dissolve carbonate into groundwater, producing the moderately hard south Florida supply.
At 131.5 mg/L, Glenvar 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 6.7 ppt warrants a certified drinking water filter — the Miami-Dade west metro industrial corridor (the Homestead Air Reserve Base AFFF plume migrating into the western Miami-Dade wellfield area), and the south Florida PFAS background contribute to Glenvar Heights' readings.
Geology & Source: Glenvar Heights in Miami-Dade County draws from Miami-Dade Water and Sewer on the Biscayne Aquifer (Miami-Dade County, south Florida) — the Biscayne Aquifer is developed in Quaternary Miami Limestone and Pleistocene Key Largo Limestone (very porous calcareous) — Florida Miami-Dade County Biscayne Quaternary karst limestone aquifer produces moderately hard water at 131.5 mg/L with TDS 326.8 mg/L in this Miami-Dade County Florida community.
