Abstract

Buried waste in old landfills is an increasing problem as cities expand and grow into areas with former waste deposits. In order to be able to manage and as far as possible reclaim land in such areas, better tools are needed for mapping and characterisation of buried waste and contaminated land. Other problems associated with landfills are leachate water and methane emissions. In the results presented internal landfill structure was successfully mapped using a combination of resistivity and time-domain IP. Differences in electrical properties can be related to different types of materials, and the groundwater level is outlined. Furthermore the results indicate that leachate water migrates into a former stream under the landfill.... (More)

Buried waste in old landfills is an increasing problem as cities expand and grow into areas with former waste deposits. In order to be able to manage and as far as possible reclaim land in such areas, better tools are needed for mapping and characterisation of buried waste and contaminated land. Other problems associated with landfills are leachate water and methane emissions. In the results presented internal landfill structure was successfully mapped using a combination of resistivity and time-domain IP. Differences in electrical properties can be related to different types of materials, and the groundwater level is outlined. Furthermore the results indicate that leachate water migrates into a former stream under the landfill. Variations in resistivity linked to variation in fluid and gas content were captured by short term monitoring. A rainfall event that occurred during the monitoring period acts as an infiltration test and the changes in resistivity outlines the water migration pattern. The results show the potential of resistivity monitoring for tracing fluid migration in the ground, and also shows patterns that may be due to increasing gas contents in line with previous studies.
