ABSTRACT An attempt was made to identify the extent of pollution in the aquifer matrix of Tirupur, a highly industrialized zone of Tamilnadu state, South India. Electrical imaging techniques were adopted with a Syscal Pro-96 system, for measuring apparent resistivity values using different electrodes separation. The first profile conducted at Valipalayam recorded a resistivity range of 45.5 Ù m w a s observed at a depth of 27 to 47 m indicating the possibility of contamination. The second profile conducted at Pethichettipuram indicates source of contamination at left end corner with a drop in resistivity
