Greenwood Water Hardness & Quality Report (2026)

Greenwood, Mississippi, in Leflore County — the Leflore County seat adjacent to Itta Bena and Carrollton on the Yazoo River in the Mississippi Delta — receives its municipal water from the Greenwood Water Division, drawing from the Mississippi River Alluvial Aquifer (Delta aquifer, Leflore County) through the central Mississippi Delta water treatment system.

The moderately hard 104 mg/L hardness and TDS of 292.6 mg/L (elevated TDS relative to hardness — suggesting dissolved iron, manganese, and minor sulfate from the Delta alluvial sediments) reflect the central Mississippi Delta alluvial aquifer's moderate calcareous and mineral-loaded character. The Mississippi River Alluvial Aquifer (Delta aquifer) at Leflore County is developed in Holocene and Pleistocene Mississippi River alluvial sand and gravel (slightly calcareous, iron-rich), Pleistocene loess (slightly calcareous — overlying loess bluff leaching contribution), and minor Eocene Wilcox Formation calcareous sand at depth.

At 104 mg/L, Greenwood'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 Leflore County central Mississippi Delta agricultural corridor, the Yazoo River Delta PFAS background from agricultural fire suppression and the Mississippi River industrial PFAS legacy, contribute to Greenwood's readings.
