What Makes Winter Haven's Water Unique?
Local geology and source profile
Winter Haven, Florida, in Polk County — the 'City of 100 Lakes' (Winter Haven is surrounded by the Chain of Lakes — a collection of natural interconnected lakes in central Polk County), historically home of Cypress Gardens (one of Florida's first theme parks — Cypress Gardens opened in 1936 as a botanical garden and water ski show venue, now Legoland Florida), a major central Florida citrus and tourism community, and a diverse Polk County community in the heart of the Florida citrus belt — draws its municipal water supply from the Upper Floridan Aquifer via the City of Winter Haven Water Division. Water hardness in Winter Haven measures 237.5 mg/L — classified as very hard.
Winter Haven's very hard supply reflects the Polk County Floridan Aquifer's highly calcareous limestone geology with limited treatment. The Upper Floridan Aquifer in Polk County is hosted in: the Eocene Avon Park Formation and Ocala Limestone (highly calcareous dolomite and limestone — Polk County's Floridan Aquifer is among the most calcareous in Florida). City of Winter Haven applies limited lime softening, producing the very hard 237.5 mg/L — substantially harder than central Florida communities with more effective softening programs.
At 237.5 mg/L, Winter Haven residents face severe hard water challenges. Weekly descaling and appliance protection measures are strongly recommended. City of Winter Haven 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 Winter Haven Water Division — the Polk County central Florida Chain of Lakes corridor (Eocene Ocala Limestone and Avon Park Formation — the highly calcareous Polk County Floridan Aquifer; limited lime softening in the Winter Haven zone); very hard supply at 237.5 mg/L — reflecting the Polk County Floridan Aquifer with limited Winter Haven treatment.
