WATER QUALITY ANALYSIS USING PHYSIOCHEMICAL PARAMETERS AND GEOSPATIAL DISTRIBUTION FOR FIVE SELECTED LAKES OF BHANDARA DISTRICT IN

In order to understand the water quality of five selected fresh water lakes of Bhandara district, Maharashtra (India), physicochemical characteristics viz. water temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), dissolved oxygen (DO),chemical oxygen demand (COD) were investigated. Samples were collected from fifteen different points of five lakes (three samples from each lake) during the pre-monsoon and post-monsoon season. To understand the spatial distribution of physiochemical parameters with the help of Geospatial Technology, we used the Inverse Distance Weighted (IDW) interpolation method. The consequences of study were validated by comparing with World Health Organization (WHO) and Bureau of Indian Standard (BIS) criteria for drinking water. All physicochemical parameters were recorded more or less similar ecological status under permissible limit during the study period. This study also reveals that, water quality parameters were found apparently lower during post-monsoon season, which could have been due to dilution of water in post-monsoon season.
