Water Well Drilling Contractors in New Jersey

Geology & Depth

New Jersey is divided by the fall line: the northern Highlands and Piedmont have igneous and metamorphic bedrock yielding water through fractures, while the southern Coastal Plain has unconsolidated sand, gravel, and clay formations with more predictable aquifers.

Most residential wells in New Jersey are drilled to 180 feet, with a typical range of 50–500 feet. Water table depth: 10-50 feet in the Pine Barrens; 50-200 feet in the northern Piedmont; 100-400 feet for confined Coastal Plain aquifers.

Permits & Licensing

New Jersey requires all well drillers to be licensed by NJDEP. The program includes written and practical examinations. No homeowner drilling exemption.

Permit authority: New Jersey Department of Environmental Protection (NJDEP), Bureau of Water Allocation; county and local health departments also issue permits. Expect $100-$500 in permit fees.

Primary Aquifer

Coastal Plain Aquifer System (Kirkwood-Cohansey, Atlantic City 800-Foot Sand) / Highland Crystalline Rock Aquifers. About 13% of New Jersey households use private wells, primarily in the Pine Barrens, Sussex County, and other rural areas.

Best drilling months: March through November; the diverse terrain allows some year-round drilling in the southern Coastal Plain.

Common Water Quality Concerns

New Jersey well water commonly contains: radon, arsenic, mercury, volatile organic compounds, PFAS, radium. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
