Well Water Testing Services in South Carolina

South Carolina does not require routine well water testing for existing private wells, but SCDES recommends annual testing for bacteria (total coliform and E. coli) and nitrates at a minimum. Approximately 20% of SC households — around 444,000 homes — rely on private wells. New well construction requires an initial water quality test before the well permit is finalized under R.61-71 standards. Well drilling is licensed by the SC Department of Labor, Licensing and Regulation (LLR) with four license classes (A through D).

Basic bacteria and nitrate testing in SC costs $50–$100, while comprehensive panels including metals, pH, hardness, volatile organic compounds, and radionuclides can run $150–$275. The Sandhills region through Aiken, Lexington, and Chesterfield counties has a known risk of naturally occurring radium in well water from deep sandy aquifers. Homes near agricultural operations in the Pee Dee region should test for nitrates and pesticides regularly.

SC's most pressing water quality concern is PFAS contamination, particularly near military installations. Joint Base Charleston recorded PFAS levels of 790,000 parts per trillion — nearly 11,000 times the EPA health advisory level. Shaw AFB in Sumter County and the former Myrtle Beach AFB also have documented contamination. Coastal wells face saltwater intrusion risk, especially on Hilton Head Island and along the Beaufort County coast. Upstate wells drilled into Piedmont crystalline bedrock may produce water with elevated iron, manganese, or radon. Understanding the geology beneath your property helps determine which contaminants to test for beyond the basic panel.

Why Choose a Licensed Provider?

South Carolina requires licensing for septic system contractors and well drillers to protect public health and the environment. Licensed providers carry proper insurance, follow state regulations, and have demonstrated competency through testing and experience requirements. Choosing a licensed provider protects your investment and ensures work meets code.
