Remote Sensing and Gis Techniques for Evaluation of Groundwater Quality in Smart City Bhubaneswar, Odisha, India

Abstract

Groundwater quality in Bhubaneswarhas special significance and needs great attention of all concernedbecause it is the majoralternate source of domestic, industrial and drinking water supply. The present study monitorsthe 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 studyare preparedby visualinterpretation of SOI toposheets on 1:50,000 scale using Arc-GIS software (Ver.10.3).Water Quality Index (WQI) was thancalculated to find the suitability of water for drinking purpose. The study revealed thatthe groundwateris 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.
