The quality of drinking water in Ethiopia is an influential environmental factor of health and water can use as a medium for disease transmission in countries on all continents; all are affected from the poorest to the richest. Moreover, in our globe millions of people are unprotected
to unsafe concentration of chemical pollutants in the drinking water. Dichlorohenols are considered as key water pollutants that are destructive to creatures at stumpy concentrations and many of them have been clustered as detrimental pollutants because of their probable to damage human health
even in low concentration. This research aimed to determine phenolic compounds from drinking water of Jimma town which is found south west of Ethiopia, by using 4-Aminoantipyridine (AAP). The sample of drinking water before and after treatment was collected for determination of pollutants
which classified as raw water (RW), treated water (TW) and system distributed water (SDW). The sample of water was preserved by phosphoric acid and sulfuric acid under pH 4 and distillation was carried out in order to remove sulfur containing compounds by addition of CuSO4 solution.
In the analysis of water using 4-Aminoantipyrine the treated water and the system distributed water have been contained 2.73 ppb and 3.64 ppb which had more phenolic compounds as compared to raw water of 1.18 ppb. Therefore, the existence of phenolic compound in both treated and system distributed
water of Jimma town drinking water has more phenolic compounds as compared to the permissible level of both Ethiopian Standard, 2 ppb and EPA Standards, 1 ppb.
