What Makes East Lake's Water Unique?
Local geology and source profile
East Lake, Florida, an unincorporated community in Pinellas County — a major north Pinellas County suburban community (East Lake is a significant unincorporated Pinellas County community in the north Pinellas–Pasco County corridor — one of the newer suburban residential communities in the greater Tampa Bay area, adjacent to Tarpon Springs and Palm Harbor; East Lake is part of the Tarpon Springs–East Lake–Palm Harbor suburban corridor that has grown significantly since the 1990s with significant upscale residential development), a diverse Pinellas County community with a primarily middle-class and upper-middle-class professional and retiree population, adjacent to Lake Tarpon (one of the major freshwater lakes in Pinellas County), home of significant golf course and gated community development, and one of north Pinellas County's growth residential communities — draws its municipal water supply via Pinellas County Utilities. Water hardness in East Lake measures 104.5 mg/L — classified as moderately hard.
East Lake's moderate hardness reflects the north Pinellas County Floridan Aquifer supply with effective treatment. The Floridan Aquifer at East Lake–Pinellas County draws from the Eocene Avon Park and Ocala Limestone (calcareous marine carbonate). Pinellas County Utilities applies effective treatment, producing the moderate 104.5 mg/L.
At 104.5 mg/L, East Lake residents encounter moderate scale accumulation. Monthly cleaning is recommended. Pinellas County Utilities consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Floridan Aquifer via the Pinellas County Utilities or Tampa Bay Water — the Pinellas County north Tampa Bay suburban East Lake corridor (Eocene calcareous Avon Park and Ocala Limestone — the calcareous-moderate north Pinellas County Floridan Aquifer; Tampa Bay Water supply with effective treatment); moderately hard supply at 104.5 mg/L in Pinellas County.
