Port Orange Water Hardness & Quality Report (2026)

Port Orange, Florida, in Volusia County on the Halifax River lagoon immediately south of Daytona Beach — a major Daytona Beach suburb and fast-growing east-central Florida community, known as one of Volusia County's most livable communities — draws its municipal water supply from the Floridan Aquifer System via the City of Port Orange Utilities Water Division, applying lime softening and conventional treatment to the Floridan Aquifer groundwater. Water hardness in Port Orange measures 71 mg/L — classified as moderately soft.

Port Orange's soft supply — extraordinary for a Florida community drawing from the raw Floridan Aquifer (typically 300–500 mg/L) — reflects the City of Port Orange's highly effective lime softening water treatment process. Lime softening ($Ca(OH)_2$ addition) precipitates dissolved calcium and magnesium as calcium carbonate and magnesium hydroxide — a traditional and effective softening technology. Port Orange Utilities operates one of Volusia County's most effective lime softening treatment systems, reducing the raw Floridan Aquifer water from its naturally extreme hardness to the treated 71 mg/L supplied to Port Orange residents. This treated supply is comparable in hardness to many northern cities drawing directly from rivers or reservoirs.

With hardness at 71 mg/L, Port Orange residents enjoy moderately soft treated water with minimal scale challenges — a significant public health and convenience benefit compared to untreated Florida groundwater. City of Port Orange Utilities consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
