Landfill Sites & Contaminated Land
Landfill waste and leachate typically constitute electrically conductive targets. Surface mapping of subsurface conductivity or resistivity can delineate landfill boundaries and associated infrastructure. Vertical profiling (or imaging) produces cross sections from which it is possible to infer waste depth and zones of potential leachate migration.
A range of geophysical techniques are appropriate to investigate the geometry and characteristics of landfills, and their application can be tailored to the specifics of a particular site.
