What Makes Brookhaven's Water Unique?
Local geology and source profile
Brookhaven, Mississippi, in Lincoln County — the Lincoln County seat adjacent to McComb and Natchez on the Mississippi Alluvial aquifer in southwest Mississippi — receives its water from the City of Brookhaven Water, drawing from the Mississippi Alluvial aquifer (Lincoln County) through the southwest Mississippi distribution.
The very soft 38.5 mg/L hardness and low TDS of 85.9 mg/L reflect the southwest Mississippi Lincoln County alluvial aquifer supply's very soft character — the Quaternary Mississippi River alluvium and Eocene Claiborne Group insoluble contribute minimal calcareous contact, among the softest water in Mississippi (compare McComb MS: 60/117 in Pike County slightly harder on the same alluvial aquifer; Grenada MS: 149/379 in Grenada County much harder; Brookhaven softest from the Lincoln County deep alluvial insoluble draw). The Mississippi Alluvial aquifer at Lincoln County — Quaternary Mississippi alluvium (insoluble — primary dilutant), Eocene Claiborne Group (insoluble — secondary dilutant), and Holocene coastal plain alluvium (slightly calcareous — minor TDS).
At 38.5 mg/L, Brookhaven's water is very soft — scale forms very slowly in appliances, dishwashers remain efficient, and no softening is needed. Annual descaling is appropriate. The PFAS level of 3.1 ppt is low — a certified drinking water filter is advisable — the Lincoln County southwest Mississippi industrial corridor contribute to Brookhaven's readings.
Geology & Source: Brookhaven in Lincoln County draws from the City of Brookhaven Water on the Mississippi Alluvial aquifer (Lincoln County, southwest Mississippi) — the Mississippi Alluvial aquifer at Lincoln County is developed in Quaternary Mississippi River alluvium (insoluble) and Eocene Claiborne Group (insoluble) — Mississippi Lincoln County Mississippi Alluvial aquifer Quaternary-Eocene insoluble supply produces very soft water at 38.5 mg/L with TDS 85.9 mg/L.
