What Makes Lockhart's Water Unique?
Local geology and source profile
Lockhart, Florida, in Orange County — an Orange County unincorporated community adjacent to Orlando and Apopka in central Florida — receives its water from Orange County Utilities, drawing from the Floridan Aquifer (Orange County) through the central Florida distribution.
The hard 184 mg/L hardness and TDS of 501.9 mg/L reflect the central Florida Orange County Floridan Aquifer supply's hard calcareous character — the Eocene Ocala Limestone and Paleocene Oldsmar Formation produce hard calcareous water typical of the central Florida communities on the Floridan Aquifer (compare Thonotosassa FL: 166.5 mg/L; Florida City FL: 272 mg/L on the harder Biscayne-Miami system). The Floridan Aquifer at Orange County — Eocene Ocala Limestone (highly calcareous — primary hardness contributor), Paleocene Oldsmar Formation (calcareous — secondary contributor), and Pleistocene surficial aquifer (slightly calcareous — minor).
At 184 mg/L with TDS 502, Lockhart's water is hard. A water softener is recommended to prevent scale buildup. A reverse osmosis system is advisable for drinking water. The PFAS level of 8.4 ppt warrants a certified drinking water filter — the Orange County central Florida industrial and agricultural corridor contribute to Lockhart's elevated readings.
Geology & Source: Lockhart in Orange County draws from Orange County Utilities on the Floridan Aquifer (Orange County, central Florida) — the Floridan Aquifer at Orange County is developed in highly calcareous Eocene Ocala Limestone and Paleocene Oldsmar Formation — Florida Orange County Floridan Aquifer Eocene-Paleocene highly calcareous aquifer produces hard water at 184 mg/L with TDS 501.9 mg/L.
