Since May 1995 GEOVision has specialized in the application of geophysics to engineering and environmental investigations. GEOVision services include geophysical measurement, analysis, and monitoring. We specialize in non-invasive methods of investigation that may reduce the overall cost and liability in engineering and environmental projects. The use of geophysics can provide a better understanding of the source, location, and migration of subsurface contaminants; subsurface geologic and hydrologic conditions; subsurface infrastructure; engineering properties of soil and rock; and earthquake hazard.
