Carriere Water Hardness & Quality Report (2026)

Carriere, Mississippi, in Pearl River County — a Pearl River County community adjacent to Picayune and Poplarville in south Mississippi — receives its water from the Pearl River Valley Water Supply district, drawing from the local Eocene Claiborne aquifer (Pearl River County) through the south Mississippi distribution.

The moderately hard 102 mg/L hardness and TDS of 285.4 mg/L reflect the south Mississippi Pearl River County Eocene aquifer supply's moderate calcareous character — driven by the Eocene Sparta Sand and Cook Mountain Formation calcareous sedimentary contacts in the Gulf Coastal Plain, consistent with the south Mississippi communities drawing from the shallow Eocene aquifer system. The Eocene Claiborne aquifer at Pearl River County — Eocene Sparta Sand (slightly calcareous — primary hardness contributor), Eocene Cook Mountain Formation (slightly calcareous — secondary contributor), and Quaternary Coastal Plain sands (insoluble — dilutant).

At 102 mg/L, Carriere'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 5.5 ppt warrants a certified drinking water filter — the Pearl River County south Mississippi industrial corridor contribute to Carriere's readings.
