Sun City Center Water Hardness & Quality Report (2026)

Island Water Association serves Sun City Center, FL (ZIP 33524) within Hillsborough County, sourcing water from the Floridan Aquifer System. Treatment occurs at local facilities managed in coordination with regional suppliers like Tampa Bay Water. The utility provides potable water to this retirement community and surrounding areas in southern Hillsborough County, ensuring compliance with state and federal standards through routine monitoring. Hillsborough County utilities conduct ongoing testing and publish annual Consumer Confidence Reports confirming adherence to EPA regulations for disinfection, pH, lead, copper, and related parameters.

The supply originates from the Floridan Aquifer, recharged via the coastal watershed encompassing Tampa Bay and surrounding rivers including the Hillsborough River. The aquifer's limestone formations — Eocene Ocala Limestone and Suwannee Limestone — dissolve over time to yield water with elevated calcium and magnesium content, resulting in a hard supply. Karst geology, characterized by solution cavities and conduits, facilitates rapid recharge while releasing significant divalent cations from the carbonate bedrock, as is typical of central Florida's groundwater resources.

Hard water leads to visible scale buildup on faucets, showerheads, and inside water heaters, with spots on dishes and glassware, and reduced appliance efficiency. Coffee makers, dishwashers, and water heaters are most affected, with shortened lifespan from mineral accumulation. Regular maintenance includes vinegar soaks for fixtures, rinse agents in dishwashers, and periodic descaling of appliances. A water softener is recommended to protect plumbing. Treatment involves chlorination, fluoridation, and corrosion control; no PFAS exceedances noted in available data; lead and copper action levels not exceeded per annual reports.
