Groundwater Quality Assessment And Its Relation To LULC Using Remote Sensing And GIS. International Conference on Groundwater-08, organized by Rajasthan University, March 19-22, 2008, Jaipur, India more

Changes in the use of the land or changes to the surface of the land can affect the quality of water eventually reaching the aquifer. In today’s scenario groundwater quality has gained significance as it is being contaminated due to various human activities and needs attention to ensure sustainable safe use. However, due to spatial variability of pH, EC, nutrients etc., determining the water quality has become difficult. The present study monitors the ground water quality and co-relates it to the land use / land cover using remote sensing and GIS techniques for Bhatinda region. Thematic maps for the study are prepared by visual interpretation of SOI toposheets and LISS-III imagery on
1:50,000 using ERDAS software. Physico-chemical analysis data of about 30 groundwater samples collected at locations forms the attribute database for the study, which are interpolated to prepare spatial distribution maps of major water quality parameters in Arc GIS software. Water Quality Index (WQI) was then calculated to find the suitability of water for drinking purpose. The overall view of the water quality index of the present study area revealed that most of the study area with > 65 standard rating of water quality index exhibited, very poor and unfit water quality.
