Electrical earth resistivity and soil temperature surveys have been conducted in the vicinity of four sanitary landfills in northeastern Illinois to test the possibility of detecting and tracing any chemical or temperature alteration of ground water by leachates from buried refuse. Reference data on water quality, levels, and movement were provided by a system of monitor wells drilled for a hydrogeologic study of the landfills. The resistivity survey, which was in homogeneous silty sand outwash, traced mineralized water from the landfill for a distance of more than 1000 feet. Apparent resistivity values were one fourth those obtained from unaffected areas. Interpretations of direction of ground‐water flow and location of discharge boundaries from the geophysical data agree vith interpretations based on the monitor well data. The soil temperature survey indicated the presence of a halo of higher temperatures around the landfill and indicated areas of surface recharge. The geophysical surveys show, in general, that chemically altered water is traceable in uniform earth materials where the depth of the water table is constant.
