What Makes Miramar's Water Unique?
Local geology and source profile
The City of Miramar Utilities Department supplies drinking water to Miramar, Florida, located in Broward County. Water is drawn from the Biscayne Aquifer and Floridan Aquifer via production wells and treated at two city-owned facilities: the East Water Treatment Plant (WTP), which uses nanofiltration, and the West WTP, which employs both nanofiltration and reverse osmosis. These advanced processes remove sediments, harmful bacteria, and certain contaminants before the treated water is distributed to homes and businesses throughout the city.
The Biscayne Aquifer is a highly porous, unconfined zone of coral rock and limestone situated 60 to 150 feet below ground, recharged by local rainfall and surface waters from Lake Okeechobee and the Everglades. The deeper Floridan Aquifer, at approximately 1,350 feet, consists of Tertiary limestone and dolomite formations with high mineral content. Florida's prevalent limestone geology dissolves calcium and magnesium into the groundwater, resulting in a hard supply with elevated mineral content that influences water chemistry.
Hard water in Miramar leads to scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. Affected appliances may require more frequent descaling, such as vinegar flushes for faucets. A water softener is recommended for households noticing soap scum, spotting on dishes, or dry skin. The city's advanced nanofiltration and reverse osmosis treatments address contaminant removal; third-party reports note PFAS, arsenic, and chromium-6 exceeding health guidelines, though utility compliance with EPA standards for lead and copper is maintained via corrosion control.
Geology & Source: Biscayne Aquifer — porous coral rock and limestone, 60–150 ft depth, recharged by rainfall, Lake Okeechobee, Everglades; Floridan Aquifer — Tertiary limestone-dolomite at ~1,350 ft; Florida limestone geology dissolves calcium and magnesium — hard

Data Sources & Methodology
Water quality data for Miramar 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.
