Buenaventura Lakes Water Hardness & Quality Report (2026)

Toho Water Authority (TWA) serves Buenaventura Lakes, a neighborhood in Kissimmee, Osceola County, Florida, distributing water to over 200,000 residents across Osceola and Polk counties. TWA sources water exclusively from the Floridan Aquifer via multiple wellfields, including the Poinciana Wellfield and Buenaventura Wellfield. Groundwater is treated at the Water Production Plant in Kissimmee through aeration, filtration, chloramination, and corrosion control before distribution. No surface water sources are utilized.

The supply originates from the Floridan Aquifer beneath the Kissimmee River watershed in central Florida's Lake Wales Ridge physiographic region. This aquifer is hosted in Eocene-era limestone formations including the Ocala Limestone, Suwannee Limestone, and Avon Park Formation, which are highly karstic and fractured. The carbonate-rich geology leaches substantial dissolved calcium and magnesium into the groundwater, resulting in a hard supply character typical of these limestone-dominated aquifers. Recharge occurs via rainfall infiltration through overlying sands and clays.

Moderately hard water in Buenaventura Lakes causes moderate scale buildup on fixtures, dishes, and appliances including water heaters, dishwashers, and coffee makers, leading to spotting, reduced efficiency, and potential clogging over time. Vinegar soaks for faucets, rinse agents in dishwashers, and periodic descaling help manage buildup. A water softener is often recommended for households with noticeable effects to extend appliance life and improve cleaning performance. Toho Water Authority reports consistently meet EPA standards, with pH typically 7.0–8.5, low lead and copper action levels, and no PFAS exceedances noted; recent testing yielded an overall B- score with C-grade health guidelines.
