Combined geophysical surveys for the characterization of a contaminated site

This study investigates the efficiency of the cement-bentonite diaphragm at the Malagrotta Municipal Waste Landfill in Rome, Italy, focusing on its hydraulic and mechanical performance over time. The landfill, one of the largest in Europe, is situated in a geologically complex area characterized by volcanic deposits, sands, gravels, and compact gray-blue clays, which provide a unique environment for waste containment. The research employs a combination of hydraulic tests, electrical resistivity methods, and surface wave analysis to assess the diaphragm's integrity and functionality.
