Temple Terrace Water Hardness & Quality Report (2026)

The City of Temple Terrace Utility operates the municipal water system serving over 25,000 residents in Temple Terrace, Hillsborough County, Florida, encompassing neighborhoods from Riverhills Park to the Temple Terrace Golf & Country Club. Water is sourced exclusively from 10 active groundwater wells tapping the Floridan Aquifer. The utility is evaluating PFAS filtration upgrades with consultant CHA, with recommendations expected for City Council in fall 2025. The system meets current federal and state drinking water standards per the official city website.

Temple Terrace's water originates entirely from the Floridan Aquifer, a groundwater-dominated supply with no defined surface watershed. The aquifer comprises Eocene limestone formations — including the Ocala Limestone and Avon Park Formation — part of the extensive karst system in northern Florida. These carbonate rocks feature high porosity and permeability from dissolution features, and naturally dissolve to release calcium and magnesium into groundwater, producing a moderately hard, mineralised supply.

Moderately hard water in Temple Terrace causes scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan while increasing energy costs. Affected appliances develop white deposits and reduced flow over time. Regular maintenance — including deliming heaters every 1–2 years and using vinegar soaks for fixtures — helps mitigate issues. A water softener is recommended for households with noticeable spotting on dishes, dry skin, or appliance damage. The 2025 Temple Terrace Water Quality Report detected over 29 PFAS chemicals — including PFOA up to 10 ppt and PFOS up to 19.5 ppt (March–May 2025), exceeding EPA's 4 ppt MCL — and rates overall quality D+ due to 7–8 contaminants including radioactive uranium above health guidelines; PFAS filtration upgrades are planned.
