Abstract
The detection of illegal buried waste by means of geophysical techniques has recently become a major effort in shallow geophysical investigations. In particular, detection and location of underground metallic storage tanks can be accomplished using different instruments and techniques. In this paper we describe the results of an investigation carried out in a tuff quarry in Riano Flaminio (north Rome, Italy). A preliminary magnetometric survey revealed the existence of anomalous zones in the analysed region. Excavation in some of the selected areas confirmed that the anomalies were generated by underground magnetic material: over 160 steel drums were found. After their removal, a new magnetometric survey was performed. On the basis of the new map, a multifrequency induction survey, a geoelectrical profile and GPR measurements were taken to extend the characterization of the subsoil.

Istituto Nazionale di Geofisica e Vulcanologia in Rome has been involved for some years with the Italian Government Waste Recycling Committee (Ufficio di Presidenza della commissione parlamentare d’inchiesta sul ciclo dei rifiuti e sulle attività illecite ad esso connesse) in performing geophysical investigations in order to check the presence in the subsoil of buried toxic waste; one of the latest investigations was undertaken in an old tuff quarry at Riano Flaminio
Summary
The ever-increasing interest in environmental problems has recently spurred the scientific community to improve geophysical methods aimed at the detection of illegal waste disposal sites. Detection and location of buried steel storage tanks can be done through several geophysical methods (Pierce and De Reamer, 1993; Foley, 1994; Vogelsang, 1995; Gibson et al, 1996; Marchetti et al, 1998). In these cases the magnetic surveys are those most frequently used allowing a quick. This paper describes different investigation techniques used in an old tuff quarry at Riano Flaminio (north of Rome) where the presence of. Thanks to the first magnetic investigation, many steel drums were found in some points of the quarry. A multifrequency induction survey, a geoelectrical profile and GPR measurements were carried out in order to characterize the subsoil in the study area
