Abstract
The quality of water leaching through chemically contaminated soil has affected underground storage. This study aims to find the region of permissible groundwater quality for domestic purposes existing near landfill. This was done by using ArcGIS, and different interpolation methods were used to know the area lying under permissible standards of water usage. It was found that for year 2014 IDW was the best spatial interpolation method, while for 2016 RBF was best with least Root Mean Square error (RMSE) and high value of coefficient of determination (R2). The results of the analysis were helpful in identifying safe zone of groundwater storage and also show that sampling locations are under tidal effect. While assessing zones, it has been found that certain zone has exceeded concentration compared to previous year. This may be attributed to leachate percolation or mixing of high TDS water.
