Abstract: Analysis of Drinking water sample was carried out to develop a data base on the quality of water being consumed in different sites of Gimbi town. Composite Drinking water samples, total of 20x3 = 60 were collected from five sites of the town. Preservation of water samples were done by adding 2 drops of concentrated HNO3 and 1 ml of 10 % NaOH prior to sampling to each water sample for heavy metal and Phenol analysis respectively before storage below 4 °C until analyzed. The samples were digested using HNO3 for heavy metal analysis. Water samples were distilled using simple distillation and distillate was collected for Phenol analysis. Parameters Temperature, Conductivity, Total dissolved solids (TDS), pH, and Heavy metals, Cr (VI), Cu (II), Cd (II); Pb (II), Zn (II), and Phenol were analyzed using AAS and UV-Vis Spectrophotometer. All samples contain Lead (II), Cadmium (II), Chromium (VI), Copper (II), Zinc (II) and Phenol, within acceptable limits recommended by WHO. The concentration of Metal ions and Phenol in the analyzed water samples are found in the Range: Lead (II) (0.34 μg/l - 0.78 μg/l), Chromium (VI) (0.3 μg/l - 0.52 μg/l), Cadmium (II) (0.3 μg/l - 0.62 μg/l), Copper (II) (0.32 μg/l - 0.97 μg/l), Zinc (II) (0.31 μg/l - 0.92 μg/l) and Phenol (0.3 μg/l – 0.99 μg/l).
