“…The magnetometric technique is the geophysical method that is most frequently used for environmental problems [Bevan 1983, Tyagi et al 1983a, Tyagi et al 1983b, Barrows and Rocchio 1990, Roberts et al 1990, Schlinger 1990, Gilkenson et al 1992, Foley 1994, Cochran and Dalton…”

“…Even if the magnetometric method is used more frequently, other geophysical techniques can be used in such investigations (Emerson et al, 1992;Pierce and De Reamer, 1993;Foley, 1994;Vogelsang, 1994;Dahlin and Jeppsson, 1995;Daniels et al, 1995;Bernstone et al, 1996;Gibson et al, 1996;Huang and Keiswetter, 1997;Godio et al, 1999;Orlando and Marchesi, 2001;Marchetti et al, 2002;Chianese et al, 2006;Ting-Nien and Yi-Chu, 2006;Hamzah et al, 2009;Ruffell and Kulessa, 2009). Indeed, the choice of the methodology to be used will depend on the physic characteristics of the materials and the depth of the targets.…”

Geophysical methods are increasingly used to detect and locate illegal waste disposal and buried toxic steel drums. This study describes the results of a test carried out in clayey-sandy ground where 12 empty steel drums had previously been buried at 4-5 m below ground level. This test was carried out with three geophysical methods for steel-drum detection: a magnetometric survey, electrical resistivity tomography with different arrays, and a multifrequency frequency-domain electromagnetic induction survey. The data show that as partially expected, the magnetometric and electromagnetic induction surveys detected the actual steel drums buried in the subsurface, while the electrical resistivity tomography mainly detected the changes in some of the physical properties of the terrain connected with the digging operations, rather than the actual presence of the steel drums.

Ground Penetrating Radar as a Functional Tool to Outline the Presence of Buried Waste: A Case Study in South Italy

2021

The ability of the ground penetrating radar (GPR) method as a rapid preliminary survey to detect the presence of illegally buried waste is presented in this paper. The test site is located in the countryside of “Sannicandro di Bari” (Southern Italy) and has a surface area of 1500 m2. A total of five parallel profiles were acquired in 2014 using a geophysical survey system instrument (GSSI) equipped with 400 and 200 MHz antennae in the monostatic configuration. Two of the five profiles were registered in a control area to compare a natural condition to a suspected waste buried zone. As a result of a processing and elaboration workflow, GPR investigations allowed us to interpret the signal qualitatively within a maximum depth of about 3 m, identifying many signal anomalies, whose characteristics can be considered typical of buried waste. The GPR response of the three profiles acquired in the suspected area showed substantial differences not found in the control’s profiles. Anomalies related to the presence of intense scattering, of dome structures not attributable to cavities, but rather to a flattening and compacting of different layers, therefore, less electrically conductive, were identified in the suspected area. The interpretation of the results obtained by the GPR profiles was confirmed by excavations carried out with bulldozers. Large quantities of solid waste illegally buried (e.g., waste deriving from construction and demolition activities, bituminous mixtures, discarded tires, glass, plastic, municipal waste) were revealed in all the sites where anomalies and non-conformities appeared compared to the control natural soil.

“…The discovery and location of these mineral ores can be detected through several geophysical techniques (Foley, 1994;Gibson et al, 1996;Marchetti, et al, 1980). Efforts have been made by geophysical and mining engineers to find the meaning of the structure of the outermost formation of the earth crust.…”

Ground magnetic survey was carried out using Scintrex proton precession magnetometer to map out subsurface structures and mineralization potentials at Alajawa area in Shanono, Kano State. 2D forward modelling was in the delineation of geological structures that are potential mineralization zones. Surfer 15 software was used to produce residual contour map. A total of five ( 5) profiles of the magnetic residual anomalies were modelled using Mag2dc software. The mineral potential locations were identified.
