Abstract [en]
Dumps and landfills are the end place of unwanted material and disposed products. Burried resources may be landfill mined and environmental pollution diminished. The problem is lack of information on unknown dump sites of former times – there remote sensing and traditional geodesy, proximal sensing techniques could be used. Near surface geophysical methods are valuable for screening of areas where drilling is limited due to technological limitations and anthropogenic unhomogenousity of material. The aim of this study was to determine whether screening of magnetometry and geoelectrical methods may be useful for old burried dumps recognition. Protonmagnetometer was used in Eastern Latvia to detect burried dump in forest, already covered by soil and vegetation. Induced polarisation and electric resistivity research was done in Southern Sweden for the macro-content analysis of dump hills composed of glass industry residuals and construction waste mixture. Surveying helped to determine macroproperties such as geomorphology and physical type of material underneath the surface. Results allowed spatially characterize dumpsite masses (location and dimensions) and identify the internal structure of a these sites. This is valuable information in order to estimate the material recovery potential of landfills.
