Dense resistivity and induced polarization profiling for a landfill restoration project at Harlov, Southern Sweden

Research output: Contribution to journalArticle

Abstract

A resistivity and time-domain induced polarization (IP) survey was conducted at a landfill Site under restoration at Harlov in Southern Sweden. The covering of the landfill had begun some years ago, without keeping precise records of the work done, as is usual in such procedures. The survey was conducted in two steps, on two adjacent areas. First, a number of geoelectrical sections were made on a partly covered area that had been investigated earlier by auger drilling, in order to assist restoration. Then, a second area that should have received its final cover was imaged, and some defects in the cover could be detected and repaired. The resistivity and time-domain IP results were consistent with the results of the geotechnical drillings, and they enabled quasi-continuous mapping along the profiles. Three-dimensional visualization showed the overall consistency of the two-dimensional lines, and helped to generate a global view of the site. In spite of some ambiguities, cover and waste Could be distinguished in most cases. In particular, fine-grained cover materials could be clearly distinguished from other cover materials.
