ASSESSMENT OF GROUNDWATER VULNERABILITY USING GIS BASED DRASTIC MODEL: A CASE STUDY OF SIPCOT-PERUNDURAI, ERODE

摘要

Water is the basic element of social and economic infrastructure and is essential for healthy society. Due to urbanization and industrialization the demand of water is increasing day by day. Thus sustainable ground water development and preservation of ground water quality should be given importance. The people living near the SIPCOT industrial estate are suffering a lot by using of contaminated water, and hence it is an important need to assess the vulnerability of contamination and to take immediate effort to safeguard the groundwater. Accordingly this study aims to identify the ground vulnerability in and around the industrial area. The objective of this work is to identify the groundwater vulnerable zone using a GIS (Geographic Information System) based DRASTIC model. The result shows that more than 62% of the groundwater in and around SIPCOT area is under very high vulnerable zone. Thus the study suggests that this model can be an effective tool for identification of pollution vulnerable zone
