摘要：The quality of ground water in Juja Location is of great significance because it is the main alternative source of drinking, domestic and industrial water supply. The study aimed at mapping the potential of ground water in the Location, assess the quality of ground water and relate it to the land use and land cover. Thematic maps for the study area were generated using GIS and Remote Sensing Techniques. Reclassification and weighted overlay tools in ArcGIS software were used to generate a ground water potential map. Very low groundwater potential was observed in the northern parts of the location while high potential was observed in the central parts. Groundwater samples were randomly collected and their locations measured using a handheld GPS. The physical and chemical properties of the water were analysed in the laboratory. Spatial distribution maps of the water quality parameters were developed using Kriging method of interpolation in ArcMap software. A drinking water quality index was then developed to describe the overall quality of groundwater in the study area. Very poor water quality was observed in Mangu farm area, Gashororo area and parts of Kenyatta Road. Excellent water quality was observed in Juja farm’s Mastore area and Happy Life Children’s Home. There is an insignificant relationship between the groundwater quality and land use in the study area.
