In recent years, increasing deterioration of groundwater quality has become a source of great concern, due to the environmental and health implications. In Awka, the Anambra state capital, access to adequate urban water supply from the state water corporation has become a serious challenge, forcing the inhabitants to depend mainly on groundwater resources, not minding the quality. Geographic Information System (GIS), a high performance computer based tool is playing a critical role in water resource management and pollution study. Mapping of groundwater contamination is an important tool for groundwater protection, land use management, and public health. In this study, the GIS software was used to analyze the quality of groundwater in Awka. Spatial variability map of different groundwater quality parameters were generated using interpolation operation in the software. Based on the Water Quality Index map, it was observed that the groundwater in the study area is good enough for drinking and domestic purposes except in the places like Akwata where the water quality was bad.
