Abstract

Geophysical techniques such as magnetic and electrical resistivity methods are being increasingly applied in investigations of landfills.

For this survey, measurements of the intensity of the earth's magnetic field were taken at regular intervals along traverses. Resistivity readings were taken at selected intervals along the same or very similar traverses. Additional resistivity depth measurements or soundings were obtained at selected points in and around the landfill.

Profiles were analyzed for individual dump structures and for overall magnetic and resistivity response. Contour maps were drawn from the measurements at the site to depict broad trends or patterns. Deeper subsurface geology was determined by the modeling of sounding data.

Results of the survey show a high correlation between the magnetic contour map and the actual dumping pattern for the landfill. Areas either lacking fill or containing old fill were delineated. Surficial layers as well as sand and clay lenses were also determined.
