Remote Sensing and GIS Techniques for Evaluation of Groundwater Quality In Smart City Bhubaneswar, Odisha, India

Abstract

Groundwater quality in Bhubaneswar has special significance and needs great attention of all concerned because it is the major alternate source of domestic, industrial and drinking water supply. The present study monitors the ground water quality. Physico-chemical analysis data of the  groundwater samples collected  at  predetermined  locations forms  the  attribute database  for  the  study, based  on  which, spatial distribution maps of major water quality parameters are prepared using  Arc-GIS software. Thematic maps for the study are prepared by visual interpretation of SOI toposheets on 1:50,000 scale using Arc-GIS software (Ver.10.3). Water Quality Index (WQI) was than calculated to find the suitability of water for drinking purpose. The study revealed that the groundwater is suitable for drinking purpose. Hill-Piper diagram that the groundwater in the region of study does meet the ''Indian Standard (IS)-10500:2012'' for potable water.
