Appraisal of groundwater vulnerability in south-central part of Bangladesh using DRASTIC model: An approach towards groundwater protection and health safety

Groundwater intrinsic vulnerability maps are considered a promising means for forestalling groundwater resources from contamination during recent years. In the present study, the DRASTIC model was used to predict groundwater vulnerability using hydro-geochemical data and Geographic Information Syste...
