Tallahassee Water Hardness & Quality Report (2026)

City of Tallahassee Utilities provides drinking water to approximately 200,000 residents in Leon County, primarily within Tallahassee city limits and surrounding areas including Betton Hills and Myers Park. The utility draws exclusively from the Floridan aquifer via multiple wells, with key facilities including the Northwood and Bragg Road wellfields. Water is treated at plants such as the Apalachee and Southwood treatment facilities before distribution through an extensive pipeline network.

The supply originates from the Floridan aquifer in North Florida's karst terrain, where water infiltrates through Eocene limestone formations including the Ocala Limestone and the Avon Park Formation. As groundwater percolates through these carbonate rocks, it dissolves calcium and magnesium, imparting a characteristically hard character. The aquifer's confined and unconfined zones in Leon County yield naturally mineralized chemistry without surface water influences.

Hard water in Tallahassee leads to scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan and often requiring premature replacements. White deposits on fixtures and reduced soap lathering are common. Regular vinegar descaling, sediment filters, and scale-resistant appliances help mitigate effects. A whole-home water softener is recommended for households with noticeable scaling. The water maintains an average pH of 7.5 and complies with lead and copper rules; independent tests note contaminants including arsenic, hexavalent chromium, nitrates, radium, and TTHMs above some health guidelines. Treatment involves aeration, filtration, chloramination, corrosion control, and fluoridation.
