Corinth Water Hardness & Quality Report (2026)

Corinth, Mississippi, in Alcorn County — the Alcorn County seat adjacent to Iuka and Booneville in northeast Mississippi — receives its municipal water from the Corinth Water Division, drawing from local Alcorn County groundwater sources through the northeast Mississippi water treatment system.

The moderately soft 71.5 mg/L hardness and TDS of 180.5 mg/L reflect the northeast Mississippi Alcorn County aquifer's moderately soft Cretaceous-Eocene calcareous sand character — somewhat softer than the central Mississippi Alluvial Plain communities (Greenwood: 104 mg/L) and consistent with other northeast Mississippi communities (Tupelo: ~75 mg/L). The Alcorn County aquifer at northeast Mississippi is developed in Cretaceous McNairy Sand (slightly calcareous — primary hardness contributor at the northeast Mississippi position), Eocene Wilcox Formation (slightly calcareous sand), and shallow alluvial deposits (slightly calcareous). The Cretaceous McNairy Sand moderately calcareous aquifer produces the soft supply.

At 71.5 mg/L, Corinth's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 4.3 ppt warrants a certified drinking water filter — the Alcorn County northeast Mississippi rural corridor has limited major AFFF military PFAS sources, and the northeast Mississippi agricultural and light industrial corridor contributes to Corinth's readings.
