What Makes Altamonte Springs's Water Unique?
Local geology and source profile
Altamonte Springs, Florida, in Seminole County north of Orlando — a major Orlando north suburban community, one of Seminole County's largest cities, a diverse community known as a hospitality and tourism corridor (Cranes Roost Park, Uptown Altamonte commercial district), home of numerous Orlando metro north corporate offices, and a rapidly growing Seminole County community in the Orlando metropolitan area — draws its municipal water supply from the Upper Floridan Aquifer via the City of Altamonte Springs Water Division. Water hardness in Altamonte Springs measures 71.5 mg/L — classified as moderately soft.
Altamonte Springs' moderate softness — much softer than the inherently hard Floridan Aquifer in Seminole County — reflects the City of Altamonte Springs' effective lime softening water treatment. The Upper Floridan Aquifer at Altamonte Springs–Seminole County is inherently very hard (the Eocene Avon Park Formation and Ocala Limestone produce raw water of approximately 200–320 mg/L in the Seminole County zone). Altamonte Springs applies comprehensive lime softening treatment — the standard Florida municipal water treatment process that precipitates calcium and magnesium, substantially reducing the Floridan Aquifer's inherent hardness to the moderate 71.5 mg/L delivered at household taps.
With hardness at 71.5 mg/L, Altamonte Springs residents enjoy soft water for a central Florida community. City of Altamonte Springs Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Floridan Aquifer System (Upper Floridan Aquifer) via the City of Altamonte Springs Water Division — the Seminole County central Florida (Eocene Avon Park Formation and Ocala Limestone calcareous karst, with effective lime softening treatment); moderately soft supply at 71.5 mg/L — reflecting the Seminole County Floridan Aquifer after effective municipal softening.
