Geophysical Services and Methods

The NJGS uses various geophysical methods to investigate the subsurface geological environment for siting ground-water supply wells, studying the occurrence of ground-water contamination, assessing geologic hazards, providing field-based quality control and assurance of consultant geophysical surveys, and for archaeologic investigations. The NJGS also prepares Requests for Proposals (RFP) and reviews proposals and reports from Environmental Consultants. The following electronic glossary elucidates the different geophysical methods used by the NJGS.

• Magnetic
• Electrical resistivity, Induced Polarization (IP) and Spontaneous Potential (SP)
• Electromagnetic (EM): Terrain conductivity, Transient EM (TEM), Ground-Penetrating Radar (GPR) and Very-Low-Frequency (VLF) EM
• Seismic Refraction and Reflection
• Gravity
• Borehole geophysics
