North Fort Myers Water Hardness & Quality Report (2026)

North Fort Myers, Florida, an unincorporated community in Lee County across the Caloosahatchee River from Fort Myers — a large unincorporated Lee County community primarily serving as a retirement and second-home community on the north bank of the Caloosahatchee River, part of the rapidly growing Fort Myers–Cape Coral metropolitan area (one of the fastest-growing metro areas in the United States), and a diverse Lee County community with significant elderly and winter resident populations — draws its municipal water supply from the Upper Floridan Aquifer via the Lee County Utilities. Water hardness in North Fort Myers measures 292.5 mg/L — classified as very hard.

North Fort Myers's very hard supply — harder than Cape Coral (197 mg/L) and Fort Myers (175 mg/L) — reflects the Lee County Utilities minimal lime softening in the North Fort Myers zone. The Upper Floridan Aquifer in north Lee County is hosted in the Eocene Ocala Limestone and Avon Park Formation (highly calcareous marine dolomite and limestone, among the most calcareous aquifer systems in Florida). Lee County Utilities applies only minimal softening to the North Fort Myers distribution zone, resulting in the very hard 292.5 mg/L — substantially harder than the Fort Myers city supply with its more complete lime softening.

At 292.5 mg/L, North Fort Myers residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. Lee County Utilities consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
