| dc.description.abstract | Groundwater is the main source of freshwater for use in agricultural, industrial, and drinking purposes in Ethiopia. Addis Ababa City gets more than 60 % of its water supply from groundwater. When groundwater moves from surface to underground sources, it passes through a large number of filtering media and hence becomes filtered. The resulting physical and chemical properties of groundwater are most importantly related to its relationship with the media, which the water encountered, and its residence time. Assessments of the groundwater quality to determine their spatial distribution have significant importance for further utilization and management of the resource. This study was focused on selected five water quality parameters: Total Dissolved Solids (TDS), Nitrates (NO3), Iron (Fe), manganese (Mn) and Fluoride (F). 108 samples from wells that are located within Addis Ababa city were collected and analyzed to determine their water quality. Their spatial distribution analysis carried out using ArcGIS and the overall Water Quality Index also computed. The results of the laboratory analysis indicated that significant number of wells have a water quality that was above WHO drinking water guide line values. This study showed that there are three kinds of water exists in Addis Ababa city: Groundwater with high iron and manganese at the northern part of the city, with high Fluoride and TDS in the central part of the city which extends to eastern direction of the city and groundwater with better water quality which complied with WHO permissible value at southern part of the City. | en_US |
