ABSTRACT
An electrical resistivity imaging survey, together with the results
obtained from ground and surface water hydrochemistry and hydrogeological
setting were used to detect pollution and subsurface flow of contaminants
from the Seri Petaling Landfill, Selangor, Malaysia. Subsurface flow of
leachate was east to west in the eastern sector of the landfill and north
to south towards a downstream area. These flows were found to coincide
with the general and local groundwater flow directions within the landfill
area. A high concentration of contami-nants exists in the downstream area
coinciding with local groundwater flow. High concentra-tions of Cl, Na,
and K were detected in the downstream area. Also, Ca and Mg are high compared
to upstream areas and the river water, probably due to the release of contaminants
from the waste body. Heavy metals concentrations are very low and do not
show any sign of pollution in the area, although they are relatively high
downstream. Leachate is also detected on the western side of the landfill,
coinciding with the general eastward groundwater flow.
