Despite the potential danger of the Repi landfill (commissioned 4 decades ago with no evaluation of hydro-geologic condition of the area) to the groundwater system, empirical work on the level of sealing of the landfill has been largely scant. The book, therefore, provides geophysical techniques involving 2-D resistivity imaging and VES for a hydro- geophysical assessment of...
