GEOPHYSICAL SERVICES

Geophysical methods can be applied to a wide range of situations requiring information about subsurface conditions. Producing correct representations of geologic features and structures using geophysical methods will greatly aid in site characterization, fate and transport modeling, and optimizing the location of monitoring and remedial wells. Utilizing the most appropriate geophysical method in an efficient manner will provide useful information that can reduce project costs by decreasing the need for intrusive characterization using boreholes. Locating man-made subsurface features is of prime importance for planning and safety purposes when excavations are necessary.
