Abstract
The main objective of this study was to assess the environmental impact of the subsurface geological
structure in Nam Son landfill by hydrogeophysical method. The Electrical Resistivity Tomography (ERT), Self-
-Potential (SP) and Very Low Frequency (VLF) method was used for geological structure investigation. Three
profiles (total 900 m long) of two-dimensional ERT, VLF density sections and 180 SP data points scattered
within the study area near the disposal site were implemented. Surface water and groundwater samples were
collected from 10 sites in the area for hydrochemical analysis. Interpretations of geophysical data show a low
resistivity zone (<15 Ω m), which appears to be a fully saturated zone with leachate from an open dumpsite.
There is a good correlation between the geophysical investigations and the results of hydrochemical analysis.
