New Jersey Geological Survey, Geological Survey Report 17; Geophysical investigations to determine bedrock topography in the East Hanover-Morristown area, Morris County, New Jersey

Gravity, seismic refraction, electrical resistivity, and induced polarization methods were used to determine bedrock topography in the East Hanover-Morristown area of Morris County, New Jersey. Previous investigations, based on well information and seismic refraction surveys, had identified parts of the East Hanover buried valley system, but not in sufficient detail for ground-water pollution investigations
