What Makes West Gulfport's Water Unique?
Local geology and source profile
The Gulfport Utilities Department manages the water supply for West Gulfport, Mississippi, serving the city's western areas within Harrison County. Water is drawn primarily from wells tapping the Pascagoula Formation and Graham Ferry Formation Aquifers, both groundwater sources within the Miocene Aquifer system. The city also purchases supplemental water from the Harrison County Utility Authority-West (HCUA-West). No specific treatment plant names are on record, but the system undergoes routine monitoring and treatment to meet EPA standards, with wells rated as having moderate susceptibility to contamination.
West Gulfport relies exclusively on the local groundwater basin tied to the Miocene Aquifer, with no traditional surface watershed. Key formations include the Pascagoula and Graham Ferry, featuring Miocene-age sands, clays, and limestones in Mississippi's coastal plain geology. These carbonate-rich layers dissolve calcium and magnesium into the groundwater, imparting a hard character to the supply. Limestone bedrock elevates mineral content compared to sandier or clay-dominated areas of the region.
Hard water in this supply leads to scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan while increasing energy costs. Soap lathering is less effective, potentially causing dry skin and spotted dishes. Regular cleaning with vinegar, installing scale inhibitors, and flushing water heaters annually are recommended. A water softener is advised to mitigate these effects and protect appliances. The 2024 Consumer Confidence Report confirms EPA compliance, with lead at 2 ppb (action level 15 ppb); treatment includes corrosion control and disinfection additives.
Geology & Source: Miocene Aquifer system — Pascagoula and Graham Ferry Formations; coastal plain limestones and sands; limestone bedrock dissolves calcium and magnesium into groundwater, producing hard water character

Data Sources & Methodology
Water quality data for West Gulfport 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.
