Summary, in English

Methane is a powerful greenhouse gas and growing concern regarding global climate changes and landfill gas is regarded as one of the major sources for methane migration to the atmosphere. In this study we present research work with the objective to evaluate the use of 3D geoelectrical resistivity to detect gas migration in landfills. Extensive field experiments were conducted at the Filborna landfill site in Helsingborg, Sweden, in August 2008. In general, the resistivity measurements showed results corresponding to results reported from previous investigations in waste. In this paper we present results showing the influence of rainfall events on the resistivity, and the correlation between gas flux and resistivity near the surface.
