What Makes Estero's Water Unique?
Local geology and source profile
Estero, Florida, in Lee County — a major southwest Florida Fort Myers suburban community (Estero is a significant Lee County village — one of the most rapidly growing communities in southwest Florida, situated between Fort Myers and Naples on the US-41 corridor; Estero is home of Florida Gulf Coast University (FGCU — a rapidly growing university in the Fort Myers–Naples metro that has built significant academic programs and an excellent NCAA athletics program in just over 20 years of operation; FGCU's 'Dunk City' run in the 2013 NCAA basketball tournament was one of the most memorable Cinderella stories in March Madness history)), home of Miromar Outlets (one of the most significant outlet retail centers in Southwest Florida — a major shopping destination in the Lee County–Collier County corridor), a diverse Lee County community with a significant retiree, resort, and growing professional population, and one of the Lee County corridor's most desirable residential communities — draws its municipal water supply from the Lower Tamiami aquifer via Lee County Utilities. Water hardness in Estero measures 161 mg/L — classified as hard.
Estero's hard supply reflects the southwest Florida Lee County Tamiami Aquifer's calcareous limestone character. The Lower Tamiami aquifer at Estero–Lee County draws from the Pliocene Tamiami Formation (calcareous marine limestone — the primary shallow aquifer in southwest Florida). Lee County Utilities applies limited softening, producing the hard 161 mg/L.
At 161 mg/L, Estero residents face regular hard water challenges. Monthly descaling is recommended. Lee County Utilities consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Lower Tamiami aquifer (Floridan system) via the Lee County Utilities — the Lee County southwest Florida Fort Myers corridor Estero (Pliocene calcareous-moderate Tamiami Formation limestone — the calcareous southwest Florida Lee County Tamiami Aquifer; limited softening); hard supply at 161 mg/L in Lee County.
