What Makes Mustang's Water Unique?
Local geology and source profile
Mustang Special Utility District (MSUD) serves 18,576 people across Mustang, Oklahoma and surrounding areas in Canadian County. The utility operates as a groundwater supplier, drawing exclusively from the Trinity and Woodbine Aquifers located beneath Collin, Denton, and Grayson Counties. Water is treated via chlorine disinfection before distribution to customers. An annual Consumer Confidence Report is published, with the 2024 CCR covering calendar year 2024 data. MSUD can be reached at 405-376-7710 for detailed water quality information or service line inventory inquiries.
The Trinity and Woodbine Aquifers are Cretaceous-age formations composed of sandstone and limestone layers rich in dissolved minerals. Calcium and magnesium concentrations are naturally elevated as groundwater percolates through these carbonate-bearing rock strata, dissolving mineral compounds along the flow path. This regional hydrogeology produces a hard water supply characteristic of north-central Texas and southern Oklahoma aquifer systems, where carbonate rock drives significant mineral uptake without natural softening processes in this part of the basin.
Hard water from MSUD causes scale buildup in water heaters, dishwashers, washing machines, and pipes over time, reducing appliance efficiency and lifespan. Customers may notice reduced soap lather, spotting on glassware, and decreased performance of heating elements. A water softener is recommended to reduce scale formation and extend equipment life; regular maintenance of water-using appliances is especially important in hard water areas. The 2024 CCR reports 8 contaminants above EPA health-based guidelines (MCLGs), and the utility employs chlorine disinfection as its primary treatment method.
Geology & Source: Trinity and Woodbine Aquifers, Cretaceous-age sandstone and limestone — dissolved calcium and magnesium carbonates produce hard water typical of north-central Texas and southern Oklahoma aquifer systems

Data Sources & Methodology
Water quality data for Mustang 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.
