Spatial and Temporal Mapping of Groundwater Quality using GIS based Water Quality Index (A Case Study of SIPCOT-Perundurai, Erode, Tamil Nadu, India)


Groundwater is an important source of drinking water especially in rural areas of Tamil Nadu. Over exploitation of groundwater for industrial use has become a major challenge. Therefore, it is very important to assess the quality of groundwater. The present study is about the geostatistical analysis of groundwater quality for SIPCOT Industrial estate, Perundurai, Erode, where Groundwater is the main source of water for drinking and irrigation purpose. The aim of the study is to map the current situation of groundwater quality in the study area. The groundwater samples collected from 35 wells in and around the SIPCOT industrial estate are used for this purpose. The major water quality parameters such as pH, EC, TDS, TA, TH, Ca, Mg, Na, K, F, Sulfates, Nitrites, Nitrates, Chlorine, Carbonate, Bicarbonate, Sodium absorption ratio, Residual sodium carbonate, and Sodium have been estimated for all the samples and the results were compared with the BIS standards. The spatial distribution map of these groundwater quality parameters were derived and integrated with WQI through GIS. GIS is used as a tool for analysis of spatial distribution of water quality. The resultant map shows the Water quality index for both pre monsoon and post monsoon season of the study area.
