What Makes Davie's Water Unique?
Local geology and source profile
Town of Davie Utilities (PWS# 4060344) provides drinking water to the Town of Davie in Broward County, Florida. The system draws groundwater from two main sources: the Biscayne Aquifer via System III Water Treatment Plant and the Floridan Aquifer via System V Water Treatment Plant. System V employs reverse osmosis to remove salts and contaminants, followed by aeration and disinfection to ensure potability for residential and commercial customers. Both plants serve the Town of Davie service area in South Florida, treating groundwater to meet all applicable EPA and state drinking water standards.
Davie's water originates from two distinct aquifer systems shaped by South Florida's limestone geology. The Biscayne Aquifer is a shallow, unconfined formation featuring porous Pleistocene coral reef limestone, while the deeper Floridan Aquifer consists of thick Eocene to Oligocene karst formations rich in calcium carbonate. Groundwater percolates through these soluble carbonate rocks over extended periods, dissolving calcium and magnesium from the bedrock and resulting in a moderately mineralized supply characteristic of South Florida karst terrain.
At moderately hard levels, Davie's water can lead to scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. Soap lathering is less effective, often requiring more detergent, and spotting may occur on glassware and fixtures. Regular descaling of appliances and cleaning of aerators is advised. Installing a water softener is recommended for households to mitigate mineral deposits and improve appliance performance. The 2025 Water Quality Report indicates good overall quality, with treatment involving reverse osmosis, aeration, and disinfection.
Geology & Source: Biscayne Aquifer — porous Pleistocene coral reef limestone; Floridan Aquifer — Eocene–Oligocene karst limestone rich in calcium carbonate; groundwater percolates through soluble carbonate bedrock, dissolving calcium and magnesium to yield moderately

Data Sources & Methodology
Water quality data for Davie is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
