Water Well Drilling Contractors in South Carolina

Geology & Depth

South Carolina's Coastal Plain occupies the eastern two-thirds of the state with productive sand, limestone, and marl aquifers. The Piedmont in the upstate has crystalline metamorphic and igneous rock — gneiss, schist, and granite — where wells depend on intersecting fractures.

Most residential wells in South Carolina are drilled to 175 feet, with a typical range of 40–500 feet. Water table depth: 20-80 feet in the Coastal Plain; 80-300 feet in the Piedmont; artesian conditions exist in parts of the lower Coastal Plain.

Permits & Licensing

South Carolina requires all water well contractors to be licensed by DHEC. There is a separate license category for well drillers and pump installers. No homeowner exemption.

Permit authority: South Carolina Department of Health and Environmental Control (DHEC). Expect $50-$200 in permit fees.

Primary Aquifer

Middendorf Aquifer / Black Creek Aquifer / Piedmont Crystalline Rock Aquifers. About 20% of South Carolina households use private wells, concentrated in the rural Piedmont upstate and Pee Dee region.

Best drilling months: Year-round; mild winters allow continuous operations, though heavy summer rains can saturate access roads in the lowcountry.

Common Water Quality Concerns

South Carolina well water commonly contains: iron, manganese, tannins, hardness, fluoride, radium in some Coastal Plain formations. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
