摘要: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. Groundwater is an essential source of drinking water for people around the world, especially in rural India. Contamination of groundwater has been observed worldwide, and it is becoming self evident that concentrated human activities lead to groundwater contamination. Contamination of groundwater reduces the supply of safe drinking water which affects the public health. 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 on groundwater composition for taking preventive measures to protect the groundwater resources in the study region. The present study demonstrates the spatial distribution of various chemical parameters, such as pH, F, Cl, iron, nitrate, alkalinity, TDS, total hardness etc. using GIS techniques for Hilauli block of Unnao district, India. A Water Quality Index (WQI) was calculated to find the suitability of water for drinking purpose. The overall analysis of the water quality index in the study area revealed that most of the area with > 50 value exhibited poor, very poor and unsuitable water quality.
