Crestview Water Hardness & Quality Report (2026)

Crestview, City of Water Dept. provides drinking water to the city of Crestview in Okaloosa County, Florida, serving approximately 25,000 residents via the municipal system. The utility sources its water exclusively from groundwater wells tapping the Floridan Aquifer, treating it at the city's water treatment plant located at 715 N. Ferdon Blvd. Treatment processes include disinfection, filtration, and corrosion control. The service area covers the urban core of Crestview and surrounding neighborhoods, with annual Consumer Confidence Reports published on the city's archive site.

The watershed for Crestview's supply is the extensive recharge area of the Upper Floridan Aquifer, spanning the coastal lowlands of the Florida Panhandle. Water infiltrates through sandy soils into the underlying limestone and dolomite strata of the Ocala Limestone and Suwannee Limestone formations, both from the Eocene epoch. This karst geology promotes rapid dissolution of minerals, yielding a hard supply with notable calcium and magnesium content. The aquifer's confined nature in parts of Okaloosa County helps protect against surface contamination while imparting the mineralized character typical of limestone-dominated regions.

Very hard water leads to significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and shortening appliance lifespan. Faucets and fixtures often display white mineral deposits, and soap lathering is poor, requiring more detergent. Maintenance tips include regular vinegar descaling for appliances, installing scale-inhibiting filters, and flushing water heaters annually. A water softener is strongly recommended to prevent damage and improve usability. Water quality in Crestview meets EPA standards overall, though 8 contaminants have exceeded health guidelines in past tests; the utility monitors for disinfection byproducts, nitrate, and radiologicals, with treatment including chlorination and aeration.
