Anomalias de cargabilidade em aterro de resíduos sólidos domiciliares

Abstract

The application of geophysical methods in environmental studies, essentially in the characterization and monitoring of contaminated areas, is growing and promising. This paper presents the application of the Induced Polarization method (IP), through the electrical profiling technique, in the determination of the leachate plume originated in the type ditch landfill. In absence of monitoring wells or other direct techniques of investigation in landfill area, the geological characterization together with the application of geophysical techniques they constitute an alternative for preliminary characterization and monitoring leached materials. However, is vital the appropriate understanding of the physical parameter due to possible alterations in the geological environment resultants of the contaminants presents. The results suggest a reduction tendency in the chargeability values in the leachate sense flow, possibly due to the dissolution for attack acid to the metallic materials present in the residues and oxides and hydroxides of iron present abundantly in the soil. © 2009 Sociedade Brasileira de Geofísica.
