Bacteriological, physicochemical and heavy metal analyses of treated water supply to the Kumasi Metropolis from the Barekese Headwork was carried out. Samples from BK4 and BK6 have their turbidity higher than the WHO acceptable limits for drinking water but the pH recorded were all within the limits of 6.5 to 8.5. Conductivity varied from 250.20 μS/cm at Asuofua (BK1) to 368.11 μS/cm at KNUST Campus (BK7). The TDS of both headwork and households were all below the standard of 1000mg/l. Calcium hardness was from 44.80 mg/L at site BK1 to 72.10 mg/L at BK6 whilst Magnesium hardness recorded 18.90 mg/L at BK5 to 30.20 mg/L also at the headwork. There was no statistical difference between the samples collected from the headwork and the other sampling sites in its total hardness (p > 0.05). Samples from BK2, BK4 and BK6 recorded Pb concentrations above the recommended limit. Ca, Mn, Fe and Mg on the hand, were all present but within the acceptable limit. The results indicated that water supplied to households in the Metropolis was potable in its physicochemical and trace metal quality except samples from BK4 and BK6 which recorded both total and faecal coliforms with the highest count being 41.20 cfu/100ml at BK4.
