Characterization of Ashes in a Landfill with Magnetic and Electrical Methods

A009 CHARACTERIZATION OF ASHES IN A LANDFILL WITH MAGNETIC AND ELECTRICAL METHODS Abstract 1 Thermal power plants waste ashes containing heavy metals have been stored and covered by domestic wastes in a landfill near Trieste (Italy). The objective of this study is to locate these ashes polluting the environment with geophysical methods. SASW 3D electrical resistivity tomography (ERT) and vertical magnetic gradient data were collected on a small test area where ashes were suspected. Niton X-fluorescence data were also collected at surface of the landfill to measure metallic compounds concentrations. SASW profile provided a high resolution S-wave velocity vertical section
