Titusville Water Hardness & Quality Report (2026)

The City of Titusville Public Works Department manages drinking water for Titusville in Brevard County, Florida, serving approximately 50,000 residents. Water is sourced from groundwater drawn from the Surficial Aquifer and the Floridan Aquifer System, with less than 2% purchased treated water from the City of Cocoa. Treatment occurs at the Mourning Dove Water Treatment Plant, where raw groundwater undergoes coagulation with lime and coagulant, disinfection, and filtration to produce potable water. The supply falls within the St. Johns River Water Management District watershed.

The Floridan Aquifer System is a major karstic limestone aquifer of Oligocene to Miocene age, encompassing the Avon Park, Ocala Limestone, and Suwannee Limestone formations, rich in calcium carbonate and dolomite. These carbonate rock formations dissolve over time, releasing calcium and magnesium ions into the groundwater and imparting a moderately mineralised, naturally hard character to the supply. The shallower Surficial Aquifer, comprising unconsolidated sands, shells, and clays of Quaternary age overlying the Hawthorn Group, provides less mineralised contributions, while the underlying karst geology remains the dominant influence on water chemistry.

As moderately hard water, Titusville's supply promotes moderate scale buildup in water heaters, dishwashers, and washing machines, reducing efficiency and potentially increasing energy costs. Soap lathering may be slightly reduced, leading to higher detergent use. Regular maintenance including descaling fixtures, installing drain screens, and flushing water heaters is advised. A water softener is optional but recommended for households noticing spotting on dishes or dry skin. In 2023, the average pH was 9.10, indicating alkaline conditions; the 2024 Annual Water Quality Report confirms regulatory compliance, though third-party tests flag potential concerns with arsenic, chromium-6, and radium above health guidelines.
