Groundwater quality has a major significance, being the major alternate source of domestic, industrial and drinking water supply and therefore it needs greater attention of all concerned. Contamination of ground water has been observed world-wide, and it is become self evident that concentrated human activities lead to ground water contamination. The present study focus on the spatial distribution of various chemical parameters such as pH, F, Cl, iron, nitrate, alkalinity, TDS, total hardness using GIS techniques for villages in Panyam mandals of Kurnool district, AP. The Water Quality Index (WQI) has to be calculated to find the suitability of water for drinking purpose. From the analysis we can identify the areas with poor or good water quality index. Geographical Information System (GIS) is a computer based system designed tool applied to geographical data for integration, collection, storing, retrieving, transforming and displaying spatial data required for proper planning and management of natural resources. The present study attempts to understand the spatial variation and influence of external factors and ground water composition for taking preventive measures to protect the groundwater resources in the study region. The present study was taken under the regions of Panyam mandals villages, Kurnool.
