What Makes Cocoa's Water Unique?
Local geology and source profile
The City of Cocoa Utilities Department serves over 19,000 residents in central Brevard County, Florida, along the Space Coast. The primary sources are groundwater wells from the Intermediate and Floridan Aquifers, supplemented by aquifer storage and recovery wells and surface water from Taylor Creek Reservoir. Water is treated at municipal facilities using softening processes and chloramine disinfection to meet EPA standards. The system processes around 9.3 million gallons daily, distributed across Cocoa and surrounding areas; the utility is based at 351 Shearer Blvd., Cocoa, FL 32922 (contact: 321-433-8700).
The Taylor Creek Reservoir watershed drains local Brevard County terrain, feeding the blended supply with groundwater from the Intermediate and Floridan Aquifers, located hundreds of feet underground. These aquifers, part of the Southeastern Coastal Plain physiographic province, feature karst structures where acidic rainwater percolates through Oligocene-Miocene limestone, selectively dissolving minerals that impart a moderately mineralised character. Surface inputs from the reservoir introduce organic variability, but the dominant aquifer geology ensures consistent mineral content at the 115 mg/L moderate hardness level.
At moderately hard levels, scale buildup occurs gradually on fixtures, reducing efficiency in water heaters, dishwashers, and washing machines over 2β5 years; faucet aerators and showerheads may clog within a year, increasing energy bills by 15β20%. Maintenance involves monthly vinegar descaling, annual filter changes, and installing scale-inhibiting showerheads. A water softener is recommended for households with hard water concerns. Testing shows EPA compliance, though health advocacy groups note exceedances for arsenic, chromium-6, nitrate, radium, and total trihalomethanes. Treatment includes softening, chloramine disinfection, and filtration.
Geology & Source: Intermediate and Floridan Aquifers β Oligocene-Miocene karst limestone and dolomite; calcium and magnesium dissolve into groundwater producing moderate hardness; blended with surface water from Taylor Creek Reservoir

Data Sources & Methodology
Water quality data for Cocoa 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 β 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 β values may differ from utility-reported figures.
TDS β 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 β Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023β2025) β 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 β 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.
