Best solutions for locating geomembrane leaks, contaminant plumes and other subsurface environmental impacts always involve geophysics. Geophysical methods are unique… in their ability to provide abundant information using non-invasive, minimal-impact technology.Subsurface geology is the study of the physical properties and location of rock and soil found below the ground surface. One of the most valuable reasons for learning about the subsurface is understanding the materials below man-made structures. These studies are commonly called geotechnical reports and are critical for building structures safely in areas with geologic
