HYDROCHEMICAL STUDIES IN AN INDUSTRIAL AREA OF VISAKHAPATNAM CITY, INDIA - A SPATIAL TECHNOLOGY APPROACHP. SWARNA LATHA AND K. NAGESWARA RAO
Remote Sensing, Geographic Information Systems (GIS) and Global Positioning System (GPS) are being effectively used as tools in water quality studies. The study was undertaken to assess the water quality in relation to domestic uses in an industrial area of Visakhapatnam city, India. Groundwater samples were collected from the bore wells in post-monsoon season and analysed for water quality parameters namely pH, Electrical Conductivity, Total Dissolved Solids, Total Hardness, Calcium Hardness, Magnesium Hardness, Chlorides, Sulphates, Phosphates, Iron and Nitrates. The area under study is severely deteriorating due to the industrial and man-made activities. Water Quality Index studies revealed that water is not suitable for human consumption in most of the locations. The aim of this study is to create the water pollution (spatial distribution) maps of industrial area using spatial technology for the better management of the city to control the pollution and also to avoid the risk of water pollutant
