Ocoee Water Hardness & Quality Report (2026)

Ocoee, Florida, in Orange County west of Orlando — a major Orlando west suburban community on Lake Apopka, a rapidly growing diverse community with significant Haitian-American, Puerto Rican, and Vietnamese-American populations, notable for its complex civil rights history (the 1920 Election Day Massacre — one of the deadliest incidents of racial violence in US history in the 20th century), now a major Orange County residential and commercial community — draws its municipal water supply from the Upper Floridan Aquifer via the City of Ocoee Water Division. Water hardness in Ocoee measures 91 mg/L — classified as moderately soft.

Ocoee's moderate softness — much softer than expected for a Floridan Aquifer supply — reflects the City of Ocoee's effective lime softening water treatment. The Upper Floridan Aquifer at Ocoee–Orange County is inherently very hard (the Eocene Avon Park Formation and Ocala Limestone produce raw water of approximately 250–350 mg/L in the Orange County zone). However, Ocoee applies comprehensive lime softening treatment — a standard water treatment process in Florida that precipitates calcium and magnesium from the raw Floridan Aquifer water, substantially reducing hardness. The effective Ocoee Water Division treatment reduces the inherently hard Floridan Aquifer supply to the moderate 91 mg/L at household taps.

With hardness at 91 mg/L, Ocoee residents enjoy soft water for a central Florida community. City of Ocoee Water Division consistently delivers water meeting all Florida DEP and EPA Safe Drinking Water Act requirements.
