Se usaron sondeos eléctricos para obtención de imágenes con un sistema Syscal Pro-96, para medir los valores de resistividad aparente con diferentes separaciones de electrodos. Se intentó determinar el alcance de la contaminación en la matriz acuífera de Tirupur, una zona altamente industrializada del estado de Tamilnadu, al sur de la India.
Key words: Industrial zone, resistivity, Tomography, 2D model, regolith, contamination. Five imaging surveys conducted across the contaminated sites reveals that shallower regoliths are highly contaminated and deeper aquifers are free from contamination except a few locations. The second profile conducted at Pethichettipuram indicates source of contamination at left end corner with a drop in resistivity 11.5 Ùm, to a depth of about 10 m.
The first profile conducted at Valipalayam recorded a resistivity range of 45.5 Ùmwas observed at a depth of 27 to 47 m indicating the possibility of contamination. Electrical imaging techniques were adopted with a Syscal Pro-96 system, for measuring apparent resistivity values using different electrodes separation.
