What Makes Lake Butler's Water Unique?
Local geology and source profile
Lake Butler, Florida, in Orange County — an unincorporated Orange County community adjacent to Windermere and Winter Garden in the Orlando west suburb — receives its municipal water from the Lake Butler Water Division, drawing from the Upper Floridan Aquifer (Orange County) through the central Florida water treatment system.
The extremely hard 307 mg/L hardness and very high TDS of 1011.5 mg/L reflect the central Florida Orange County Floridan Aquifer's deeply evaporitic character — driven by the deep Paleocene Cedar Keys Formation evaporitic dolomite at this Orange County position. The Upper Floridan Aquifer at Orange County is developed in Eocene Ocala Limestone (calcareous), Eocene Avon Park Formation (dolomite — calcareous), and Paleocene Cedar Keys Formation (evaporitic dolomite-anhydrite — dominant TDS and extreme hardness contributor). The deep Cedar Keys evaporitic zone at Orange County produces the extreme supply.
At 307 mg/L with TDS 1012, Lake Butler's water is extremely hard. A water softener and reverse osmosis system are essential. Scale forms almost immediately on all surfaces, appliances fail rapidly without treatment, and drinking water filtration is critical. The PFAS level of 12.2 ppt is among the highest in this dataset — the Orange County Orlando metro area Orlando International Airport (AFFF — one of the largest airport PFAS sources in the southeast USA) and the central Florida tourism-industrial PFAS complex are the primary PFAS contributors.
