Abstract
An application of an integrated approach including geochemical analyses and
geophysical investigations, aimed at the detection of possible leaks originating
from an urban solid landfill, is proposed. The objective of the subsurface
geophysical investigation was to use non invasive methods to delineate buried
waste zones. The information collected in this investigation may be useful to
locate possible leachate pockets and to optimize subsequent sampling and
remediation.
Methods used at the site focused on the electrical insulating properties of the
nonmetallic (glass, plastic) containers and the electrical conducting properties of
possible leaking fluids and clay soil.
As a case study the example of a municipal solid waste landfill, located in SE
Sicily, is presented.
Keywords: geophysics, resistivity, tomography, landfill, liquid percolation,
leachate.
1 Introduction
Leachate plumes originating from municipal solid waste (MSW) landfills are
potential sources of contamination for water resources, including ground and
surface water and littoral environments, where the naturalistic equilibrium may
be severely influenced if exposed to pollution [1,2]. The related consequences
for the mentioned ecosystems are difficult to be evaluated and sometimes cannot
be predicted. For these reasons and in order to prevent leakage from MSW
landfills, a preliminary detailed geological investigation is usually done to
