In developing country like India greater attention has been focused so far only on the ground water pollution. Unlike water the study on the soil contamination has not been much attended yet. In this background, it becomes necessary to study the soil contamination in Dindigul, where the soil is mostly degraded by tannery effluents. In order to assess the extent and level of soil contamination, soil samples were takeq at 60 locations in and around tannery industries and tested for various chemical parameters like Electrical conductivity, pH, Nitrogen, Phosphorus, Potassium, Iron, Manganese, Zinc and Copper. The GIS has its application in modeling pollution characteristics via generating continuous surfaces, overlay analysis etc. The interpolation method "kriging" was used to generate continuous surfaces for all the soil parameters. It is a process of using points with known values to estimate values at unknown points ie., a process of filling in data between the sample points. The overlay analysis was then performed by assigning weightages to the soil parameters to arrive the contamination levels. The results show that most of the areas were highly contaminated which make the land unfit for agriculture. Copyright © Enviromedia.
