Abstract: Pollution of ground water either from geogenic or anthropogenic sources has become a thing of health concern in the city of Addis Ababa. This study assesses the quality hazards of ground water resource by sampling some boreholes from Yaka-Kotebe and Summit-Bole area of the Addis Ababa. Collected samples were analyzed for water quality parameters using standard procedures. The parameters determined were Electrical Conductivity (EC), pH, Total Dissolved Solids (TDS), potassium (K+), sodium (Na+), calcium (Ca2+), magnesium (Mg2+), iron (Fe), chloride (Cl-), floride (F-), nitrate (NO3 -) and sulphate (SO4 -2). Results were subjected to evaluations using Arcgis, Aquachem and SPSS for descriptive and analysis of the results. Ca-Na-HCO3 and Na -Ca-HCO3 were the dominate water type in the study area. The mean value of iron (0.55 mg/l) and floride (3.2 mg/l) were above World Health Organization standards for drinking water in Yaka-Kotebe area. Similarly, the mean value of TDS (862 mg/l) and EC (1356 mg/l) for water samples from Summit-Bole were greater than maximum permissible standards for drinking water Guide Line of World Health Organization. It was also observed from EPA secondary data upstream to downstream along Akaki rivers increase in the concentrations of heavy metals, TDS, EC, pH, and temperature and associated with the generally declining DO level. Generally, in the study area from water sample analysed about 50% of water samples were greater than World Health Organization maximum permissible standards for drinking water for water quality parameters such as Fe, F-, NO3 -, EC, and TDS. Therefore, elevated values of these parameters are of great concern to public health when the water from these boreholes is consumed by people without treatment.
