To analyze and study the problem of pollution and contamination of soil and groundwater due to industrial spills, landfills leakage or other accidents it is very important to understand the controlling contaminant transport processes. The environmental geophysic provides a wide spectrum of tools to identify the most relevant hydrogeophysical parameters able to study the process occurring in the subsoil with good reliability at time and costs reduced. Moreover, obtained the physical characteristics of the soil, it is possible to define and optimize the simulated models to study and manage the contamination phenomenon.
