What Makes Casselberry's Water Unique?
Local geology and source profile
Casselberry, Florida, in Seminole County — a major central Florida Orlando suburban community (Casselberry is a significant Seminole County city — a central Florida suburb adjacent to Altamonte Springs and Winter Park; Casselberry is part of the greater Orlando metropolitan area's north Seminole County suburban belt; Casselberry has developed as a diverse suburban community with a significant mix of retail and residential development along US Route 17–92, one of the most important historic commercial corridors in central Florida), a diverse Seminole County community with a significant Puerto Rican-American, Hispanic-American, and diverse suburban family population (Casselberry has one of the more significant Puerto Rican-American communities in Seminole County), adjacent to Winter Springs and Longwood in the central Florida Seminole County corridor, home of a significant middle-class and working-class suburban population serving the broader Orlando economy — draws its municipal water supply via the City of Casselberry Water Division. Water hardness in Casselberry measures 239.5 mg/L — classified as very hard.
Casselberry's very hard supply reflects the central Florida Seminole County Upper Floridan carbonate karst's highly calcareous character. The Upper Floridan Aquifer draws from Eocene Avon Park and Ocala Formations (calcareous — Floridan karst). Very limited softening produces the very hard 239.5 mg/L.
At 239.5 mg/L, Casselberry residents face significant hard water challenges. Regular water softeners and descaling are strongly recommended. City of Casselberry Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Upper Floridan Aquifer via the City of Casselberry Water Division — the Seminole County central Florida Orlando suburban Casselberry corridor (Eocene calcareous Avon Park and Ocala Formations — the extremely calcareous central Florida Seminole County Floridan carbonate karst; very limited softening); very hard at 239.5 mg/L in Seminole County.
