Abstract Geophysical techniques have become increasingly crucial for characterizing landfills, offering noninvasive methods subsurface exploration and contamination assessment. In this study, an integrated geophysical approach—utilizing magnetic, electrical resistivity tomography (ERT), transient electromagnetic (TEM) surveys—was employed to characterize the Weidenpesch landfill in Cologne, Germany assess potential groundwater contamination. The results from these were consistent, effectively delineating boundaries identifying possible waste body was distinguished by its relatively low values with average value of 1–10 Ω·m western central parts 20–50 at eastern part contrast surrounding high-resistivity gravelly sand layer (several hundreds Ω·m), a depth up 15 m. variability conductivity magnetic susceptibility across different sections indicated heterogeneity buried materials. Additionally, ERT TEM data indicate (below 5 Ω·m) depths 20–25 A correlation borehole suggests that may represent contaminated coal/clay layer. Furthermore, repeated measurements revealed significant variation over time, highlighting need continuous monitoring. This study demonstrates effectiveness approach providing comprehensive understanding conditions, which is essential informed environmental management remediation.
