South Carolina Tap Water Quality
EPA water quality data for 150 community water systems serving 1,801,177+ people in South Carolina. Click any system to see violations, lead testing results, and a safety grade.
South Carolina draws drinking water from Piedmont reservoirs, the Santee-Cooper lake system, and Coastal Plain aquifers. Disinfection byproduct violations are the most common compliance issue, particularly among smaller systems. Radium and other naturally occurring radionuclides appear in some Coastal Plain groundwater.
