Lexington's water supply draws from watersheds typical of the South Carolina Piedmont region, influenced by the underlying crystalline rock formations of the Piedmont geologic province, including metamorphic and igneous rocks from the Precambrian to Paleozoic eras. Groundwater and surface sources interact with these low-limestone soils and fractured bedrock, contributing to the soft water character observed in Lexington County. The regional geology features minimal carbonate dissolution, resulting in very soft to moderately mineralized water profiles across the area.

With soft water, Lexington residents experience minimal scale buildup in plumbing, appliances, and fixtures. Appliances like water heaters and dishwashers require little extra maintenance compared to harder water areas, and soap and detergent efficiency is high — reducing overall usage. No water softener is recommended or necessary. Occasional monitoring for corrosion due to low mineral content is advisable, as soft water can be slightly more aggressive toward metal plumbing. The utility monitors all regulated substances including nitrate, fluoride, copper, lead, haloacetic acids, and total organic carbon, with treatment involving standard disinfection via chloramines.
