Horizon West Water Hardness & Quality Report (2026)

The Orange County Water Division supplies drinking water to residents in Horizon West, an unincorporated community within Orange County, Florida. This utility draws its entire water supply from the Floridan Aquifer, utilizing several wellfields, including those situated near Lake Apopka and Wekiva. Water undergoes treatment at facilities like the Wekiva Water Treatment Plant and the Lake Highland facility. Here, the groundwater is treated through aeration, filtration, and disinfection using chloramines, ensuring it meets all state and federal drinking water standards before distribution to homes and businesses in southwest Orange County.

The water originates from the Upper Floridan Aquifer, a significant geological feature within the St. Johns River Water Management District. This aquifer is characterized by extensive formations of limestone and dolomite, belonging to the Eocene Avon Park and Ocala Limestone groups. These rock layers are highly permeable, riddled with karst features like sinkholes and underground conduits. As groundwater flows through these soluble carbonate rocks, it dissolves substantial amounts of calcium and magnesium minerals, giving the water its naturally hard quality and mineral-rich profile, which is typical for central Florida's groundwater.

Homeowners in areas with moderately hard water like Horizon West might observe some scale accumulation on faucets and showerheads, and may find that soap doesn't lather as readily. Appliances such as coffee makers, dishwashers, and water heaters can be affected by mineral deposits over time, potentially reducing their efficiency. Simple maintenance, like occasional descaling of coffee pots with vinegar or using rinse aids in the dishwasher, can help manage these effects. For a more comprehensive solution to extend appliance longevity and improve cleaning, installing a whole-house water softener is a practical option, though not medically necessary.
