North Port Water Hardness & Quality Report (2026)

North Port, Florida, in southern Sarasota County — one of Florida's fastest-growing cities, developing rapidly on the former Port Charlotte canal development grid — draws its municipal water supply from the Floridan Aquifer System (specifically the Lower Tamiami Aquifer and Peace River Formation) via the City of North Port Utilities Water Division, pumping from deep calcareous Sarasota County aquifer wells serving the North Port area. Water hardness in North Port reaches 300.5 mg/L — classified as very hard, among the harder supplies in southwest Florida.

North Port's very hard supply reflects the Sarasota County Floridan Aquifer System's deep calcareous limestone geology. The Tamiami Aquifer in Sarasota County accesses the Pliocene Tamiami Formation (shallow marine calcareous limestone and calcareous sand) and the Miocene Peace River Formation (marine calcareous marl and limestone of the Bone Valley Phosphate District — famous for its calcareous phosphorite). Deeper Floridan System access in North Port may extend to the Eocene Avon Park Limestone (pure marine carbonate limestone of the deep Florida Platform). These deep calcareous formations produce very hard groundwater throughout the Charlotte Harbor–Sarasota County area. North Port Utilities applies conventional treatment but not full RO softening, maintaining the naturally very hard 300.5 mg/L.

At 300.5 mg/L, North Port residents face significant hard water challenges. Scale deposits form rapidly on all fixtures and tile — monthly descaling with citric acid solution is essential maintenance. City of North Port Utilities Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
