What Makes Auburndale's Water Unique?
Local geology and source profile
Auburndale, Florida, in Polk County — a Polk County city adjacent to Winter Haven and Lakeland in central Florida — receives its municipal water from the Auburndale Water Division, drawing from the Floridan Aquifer (Polk County) through the central Florida water treatment system.
The moderately hard 116.5 mg/L hardness and TDS of 281.6 mg/L reflect the central Florida Polk County Floridan Aquifer's moderately calcareous character — somewhat softer than the north Florida Floridan communities (Gainesville: ~150 mg/L; Ocala: ~160 mg/L) due to the south Polk County position where the Floridan Aquifer is deeper and slightly less calcareous. The Floridan Aquifer at Polk County is developed in Eocene Avon Park Formation (calcareous limestone — primary hardness contributor), Oligocene Suwannee Limestone (calcareous), and Miocene Hawthorn Group (slightly calcareous phosphatic). The Eocene-Oligocene calcareous limestone produces the moderately hard central Florida supply.
At 116.5 mg/L, Auburndale's 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 6.2 ppt warrants a certified drinking water filter — the Polk County central Florida phosphate-industrial corridor (the largest phosphate mining district in the USA), MacDill Air Force Base (Hillsborough County — AFFF), and the central Florida mining PFAS background contribute to Auburndale's readings.
