oun<l water is major preferred sources of thinking water in many areas of Ethiopia, but various arnhropologic factors, such as agricultural practices (inorganic nitrogen Icrtilizers), urbanization (animal and human wastes) and industrialization are causing nitrate contamination. . ' The high nitrate pollution in drinking ground water has a signiticanr impact on health and the environment. The aim of the present study was to determine nitrate level of ground water in Wombertna district ii;pm seven randomly selected sample locations by Uv-vis Spectrophotometric method. Twenty eight ground water samples were collected from the hand <lug wells. The number of wells selected for study accounts 2 l % of the total available hand dug wells in the area. The analysis was done estimating nitrate level at!.,,.., 410 nm water samples • ABSTRACT conversed to nurophcnoldisuphonic acid straw color which by the reaction of NO) with PD1\ in the presence. or ammonia solution. The average results of nitrate concentration measured from different ,kcbdes: Markuma, Buraler, Wogedad, Scbadar, Wazingiswegercb, Shendi Dcnd Boledin and Hirer in mg N0-3 L"1 were 2.837, 3.(i(i&, 6.339: 2.226, 1.054, I .'276 and 5.338 respectively. The greater ground water nitrate contamination was observed from Wogcdud and I liret, may be correlated to high use of nitrogen fertilizers and their population dense. Ilic results of nitrate level in ground water to the study urea varied lo the range of 1.054±0.275 ppm to 6.339±0.919 ppm. However, the level or nitrate conceuation of the ground water was within the acceptable for drinking, per intcrnationul standards permissible 1i111i~ 50 mg/]. nitrate in drinking water.
