Surface and ground water have been under increasing threat of pollution in recent years due to improper management of vast amount of wastes generated by various human activities. Improper dump sites have served many years as ultimate disposal site for all types of waste in developing countries such as Ethiopia. Physical, chemical and biological processes interact simultaneously to bring about the overall decomposition of the wastes. One of the by-products of this mechanism is chemically laden leachate and it is a potentially hazardous waste from waste disposal sites. If not deal properly such kind of dumping site can cause pollution to groundwater (because of Leachates) and surface water (through contaminant transportation by flooding and ground water movements). Therefore, this study asses ground and surface water quality near to sebatamite waste disposal dumping site of Bahir Dar city.Water samples were collected from 8 sampling points of ground water and2 sampling points ofsurface water from October 7/2020.Fifteen water quality parameterssuch asPH, Turbidity, Temperature, chloride, EC, TDS, TS, BOD, DO, Nitrate, Ammonia, Phosphate, manganese and total coliform were analyzed for both ground and surface water. It was found that waterquality parameter such asTDS, Turbidity, BOD, EC, Phosphate, TS and TC are above the acceptable limit for surface water. While the remains were fluctuated depending sampling point. For ground water samples, Turbidity, DO, BOD, EC, Phosphate, TS, TDS and TC are above the acceptable limit. The remains were above acceptable limit, except manganese, fluctuated depending sampling point.The correlation analysis results showpH was negatively strong correlated withT0,Turbidity,and Cl- .PO43- was positively strong correlated with NO3, Mn and TS.NO3was positively strong correlated withCl-, Mn and TC.Cl-was positively strong correlated with TC and Mnwas positively strong correlated with TS and TC. All positive correlations were significant. TS was weakly correlated with pH, Turbidity, DO, NO3, BOD and DOweakly correlated with, PH, TDS, Turbidity and To.All negative correlations were not significant.A mechanism should be developed for periodic assessments and monitoring of the concentration levelspollutants in surface and groundwater.
