Longwood Water Hardness & Quality Report (2026)

The City of Longwood draws its drinking water from groundwater wells that tap into the Floridan Aquifer. This vast underground system supplies central Florida, with recharge areas in the north where rainwater filters through sandy soils into underlying limestone. The water is treated with hypochlorite for disinfection at facilities managed from 175 W. Warren Ave, Longwood, FL 32750. The utility serves over 23,000 residents, primarily in Seminole County, and consistently meets federal Safe Drinking Water Act standards, with no reported EPA violations.

The Floridan Aquifer is characterized by its geology: porous, karstic limestone formations like the Ocala Limestone and Avon Park Formation, dating back to the Tertiary period. As groundwater flows through these carbonate rocks, it dissolves significant amounts of calcium and magnesium. This natural process enriches the water with minerals, resulting in a supply that is notably hard. The aquifer's extensive nature means this mineral content is a consistent feature of the groundwater drawn for Longwood's supply, influencing its taste and potential for scale.

Very hard water can lead to scale buildup in household appliances like water heaters, dishwashers, and washing machines, potentially reducing their efficiency and lifespan. You might notice stubborn deposits on fixtures, stiff laundry, and poor soap lathering. Homeowners can mitigate these issues with monthly appliance rinses using vinegar, installing scale inhibitors, or using rinse aids in dishwashers. For comprehensive protection and to extend equipment life throughout the home, a whole-house water softener is strongly recommended. While Longwood's water meets all health guidelines, residents should be aware of potential issues related to disinfection byproducts and trace contaminants.
