What Makes Gautier's Water Unique?
Local geology and source profile
Gautier, Mississippi, in Jackson County — a Jackson County city adjacent to Pascagoula and Ocean Springs on the Mississippi Gulf Coast, a coastal community on the Singing River (Pascagoula River) estuary — receives its municipal water from the Singing River Utility (SRU) or Jackson County Water and Sewer District, drawing from the Gulf Coast aquifer system through production wells in Jackson County.
The soft 55.5 mg/L hardness and TDS of 132.3 mg/L reflect the Jackson County Gulf Coast aquifer's sandy character. The Gautier area wells access the Eocene Claiborne Group (Tallahatta and Sparta Sand — fine calcareous sand and clay, low carbonate content) and the Miocene Hattiesburg Formation (sandy clay — insoluble). The sandy Gulf Coastal Plain sediment beneath Jackson County produces the soft groundwater characteristic of the Mississippi Gulf Coast municipal supplies.
At 55.5 mg/L, Gautier's water is very soft — essentially no scale forms, soap lathers abundantly, and appliances maintain good efficiency. Annual descaling is sufficient. The PFAS level of 3.7 ppt warrants a certified drinking water filter — Keesler Air Force Base (Biloxi, Harrison County — AFFF in the Gulf Coast watershed), the Pascagoula shipbuilding industrial complex (Jackson County — Ingalls Shipbuilding), and the Mississippi Gulf Coast PFAS background contribute to Gautier's readings.
Geology & Source: Gautier in Jackson County draws from the Singing River Utility or Jackson County groundwater (Mississippi Gulf Coast aquifer — Eocene Claiborne Group and Miocene Hattiesburg Formation calcareous sand, Jackson County) — the Mississippi Gulf Coast aquifer produces soft groundwater at 55.5 mg/L with TDS 132 mg/L in this Jackson County Mississippi city.
