Overview

Electrical resistivity tomography identifies leachate and gas distributions in a landfill, suggesting potential environmental risks.

Key Points

  • Extensive low-resistivity zones indicate leachate accumulations in the southeastern sector, posing environmental risks.
  • High-resistivity anomalies were observed related to biogas pockets, although they constitute less than 1.1% of the total volume.
  • Electrical resistivity tomography facilitated effective imaging and characterization of subsurface contaminants without intrusive methods.
  • Findings suggest improvements in existing leachate and gas collection systems for better post-closure management.
