What Makes Moss Point's Water Unique?
Local geology and source profile
Moss Point, Mississippi, in Jackson County — a Jackson County city adjacent to Pascagoula and Escatawpa in southeast Mississippi — receives its water from the Moss Point Water System, drawing from the Escatawpa River or Jackson County groundwater (Jackson County) through the southeast Mississippi distribution.
The moderately hard 130.5 mg/L hardness and TDS of 398 mg/L (TDS elevated relative to hardness — reflecting the Gulf Coastal Plain aquifer's dissolved sulfate and sodium from the Tertiary marine sediment formations) reflect the southeast Mississippi Jackson County supply's moderate calcareous character — typical of Gulf Coast Mississippi communities drawing from the Tertiary Citronelle Formation aquifer. The Jackson County Gulf Coastal Plain aquifer — Tertiary Citronelle Formation (calcareous — primary hardness contributor), Quaternary terrace deposits (slightly calcareous — secondary contributor), and Tertiary Pascagoula Formation (slightly calcareous — TDS contributor).
At 130.5 mg/L, Moss Point's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 6.5 ppt warrants a certified drinking water filter — Keesler Air Force Base (Harrison County — AFFF, nearby) and the southeast Mississippi Jackson County Gulf Coast industrial corridor contribute to Moss Point's elevated readings.
Geology & Source: Moss Point in Jackson County draws from the Moss Point Water System on local Jackson County groundwater (Jackson County, southeast Mississippi) — the Gulf Coastal Plain aquifer at Jackson County is developed in Tertiary Citronelle Formation (calcareous-evaporitic) and Quaternary terrace deposits (calcareous) — Mississippi Jackson County Gulf Coastal Plain Tertiary calcareous aquifer produces moderately hard water at 130.5 mg/L with TDS 398 mg/L.
