Apopka Water Hardness & Quality Report (2026)

The City of Apopka Utilities Department serves approximately 60,000 residents in the City of Apopka and surrounding areas within Orange County, Florida. The water supply is sourced entirely from five groundwater treatment plants drawing from the lower Floridan Aquifer. Key facilities include the Wekiwa and Apopka wellfields, with treatment involving aeration, filtration, chlorination, and fluoridation to meet federal and state standards. The utility publishes annual Consumer Confidence Reports (CCRs) verified by the Florida Department of Environmental Protection, confirming compliance with EPA regulations.

Apopka's water originates from the Floridan Aquifer system within the broader St. Johns River Water Management District watershed. The aquifer's limestone and dolomite formations from the Eocene period — primarily the Ocala Limestone and Avon Park Formation — contribute dissolved minerals, producing a moderately hard supply with elevated calcium and magnesium. This geology leads to naturally occurring hardness, with surface influences minimal due to the deep groundwater source, preserving the mineralized character from subsurface rock dissolution.

With a moderately hard supply at 140 mg/L, residents may notice reduced lathering from soap and shampoo, as well as scale buildup in dishwashers, washing machines, and water heaters. Faucet aerators and showerheads can clog over time, reducing flow efficiency. Regular annual descaling of appliances and vinegar soaks for fixtures are recommended. A water softener benefits households experiencing noticeable effects. Recent CCRs confirm full compliance with no violations; trihalomethanes are well below limits (0.14–0.28 mg/L range), and lead and copper rule compliance is maintained through corrosion control.
