Spatial Mapping Of Ground Water And Its Quality Checking Using GIS

Groundwater is an important component of our nation’s fresh water resources. It plays a key role in meeting the water needs of various user-sectors in the nation. The natural resource cannot be optimally used and sustained unless the quality of water is assessed. In the present study, the impact of various industries on groundwater quality around the Kanjikode area in Pudussery panchayat, covering an area of 16.88sq km in Palakkad was carried out. For the study, data collection includes collected water quality data, well locations, landmarks etc. The above said data has been collected from various areas of Pudussery panchayat. After the data collection, base map has been prepared using QGIS software. The water quality database is analysed and then used as attribute database for the preparation of thematic maps showing distribution of various water quality parameters. Water Quality Index has been calculated for various parameters such as pH, Turbidity, Total hardness (TH), Chloride, Total dissolved solids (TDS), Alkalinity, Dissolved Oxygen (DO) and Fluoride. Water Quality Index map is also developed. The results obtained are presented in the form of maps, used for better understanding of present water quality scenario of the study area. Analysis reveals that the groundwater of the region needs specific treatment before put to use.
