What Makes Gulfport's Water Unique?
Local geology and source profile
Gulfport, Florida, in Pinellas County — a Pinellas County city adjacent to St. Petersburg and South Pasadena on Tampa Bay — receives its water from the City of Gulfport Water, drawing from the Floridan Aquifer (Pinellas County) through the Tampa Bay distribution.
The very hard 215 mg/L hardness and TDS of 617.3 mg/L reflect the Tampa Bay Pinellas County Floridan Aquifer supply's very hard calcareous character — the Eocene Avon Park Formation and Oligocene Suwannee Limestone produce very hard water throughout the Tampa Bay Floridan communities (compare On Top of the World FL: 259/796 in Marion County harder; South Daytona FL: 241.5/723 comparable; Gulfport very hard on the Pinellas County Floridan draw). The Floridan Aquifer at Pinellas County — Eocene Avon Park Formation (calcareous — primary hardness contributor), Oligocene Suwannee Limestone (highly calcareous — secondary contributor), and Quaternary Tampa Bay coastal sand (insoluble — minor dilutant).
At 215 mg/L with TDS 617, Gulfport's water is very hard. A water softener is strongly recommended to prevent rapid scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 9.3 ppt warrants a certified drinking water filter — the Pinellas County Tampa Bay industrial and military corridor contribute to Gulfport's elevated readings.
Geology & Source: Gulfport in Pinellas County draws from the City of Gulfport Water on the Floridan Aquifer (Pinellas County, Tampa Bay, Florida) — the Floridan Aquifer at Pinellas County is developed in Eocene Avon Park Formation (calcareous) and Oligocene Suwannee Limestone (highly calcareous) — Florida Pinellas County Floridan Aquifer Eocene-Oligocene Tampa Bay calcareous supply produces very hard water at 215 mg/L with TDS 617.3 mg/L.
