Ridgeland Water Hardness & Quality Report (2026)

Ridgeland, Mississippi, in Madison County adjacent to Reservoir (the Ross Barnett Reservoir) in the northern Jackson metropolitan area, receives its municipal water from the City of Ridgeland Water Department, drawing from both the Ross Barnett Reservoir (Pearl River impoundment) and local groundwater wells tapping the Wilcox Group aquifer. Ridgeland is a prosperous suburb of Jackson on the eastern shore of the Ross Barnett Reservoir — one of Mississippi's largest man-made lakes, providing both water supply and recreation for the central Mississippi region.

The moderately soft 68.5 mg/L hardness and low TDS of 171.1 mg/L reflect Mississippi's characteristic coastal plain geology in the Central Embayment. The Wilcox Group and Tuscaloosa Group — Eocene and Cretaceous age coastal plain deposits — are composed almost entirely of quartz sands, silts, and clays with negligible calcium carbonate content. These Tertiary coastal plain sandstone and sand formations were deposited as river deltas and nearshore marine sands during repeated Cenozoic sea level fluctuations, and unlike limestone or dolomite aquifers, they dissolve very little mineral content into percolating water. The Ross Barnett Reservoir on the Pearl River adds similarly soft surface water character from the central Mississippi watershed.

At 68.5 mg/L, Ridgeland's water is pleasantly soft — comfortable for everyday household use. Soap lathers easily, appliances scale slowly over many months, and glassware from the dishwasher shows minimal spotting. Semi-annual descaling of kettles and coffee machines is adequate for this soft supply. The primary water quality concern for Ridgeland residents is the PFAS level of 4.2 ppt — moderate but worth monitoring. A certified drinking water filter is a practical addition for residents preferring enhanced daily drinking water protection.
