dc.description.abstract	water sampl« collectedfrom Andassa spring wa1rr which is located abom 53 km J011lh east ,/'·om Bahir Dar city wa.1· analyzed for some selected properties such as temperature. pH, electrical conductivity, total dissolved sotids, iuiul hardness. total alkalinity and 1/le concentration of selected 1nc!!.1/j· such as calcium. magnesium, potassium, :i11£·, C(>pper, cadmium and lead wc>te determined. The concentration ofmetal» sucl: as calcium. magnesium, potassium: zinc, copper, eadmiutn and lcod concentrations i11 the water sompl« \Vi:s determined ustng ihe palintest photometer. Si~1dord solutions of the onaiyte mewls were prepared for the !Cf'-OES In contrast r!l the Wl.1.0 minimum recommended few!.!

Among the analyzed metals, Ph and Cd were nor in a detectable level in the water samptc which may be due lo.;il1e [acr that the sampling area is free from industriol and anthropogonical pollution.	en_US
