Assessment of Physicochemical and Bacteriological Parameters of Drinking Water Quality of Urban Water System in Abuja Metropolis, Nigeria
By Nneoma Mirabel, et al.The study evaluates the physicochemical and bacteriological parameters of the drinking water quality of the urban water system in Abuja Metropolis, Nigeria. Water samples from four (4) treated water tanks (TW1-4) and twelve (12) supplied locations (L1-12) were analyzed for their physical (Colour, Temperature, Turbidity, Total Dissolved Solid), chemical (Electricity Conductivity, Total Alkalinity, Total Hardness, Chloride Ion, Salinity, Total Dissolved Solid, Dissolved Oxygen, Iron, Phosphate, Sulphate, Nitrate, Nitrite, Manganese, Residual Chlorine and MPN) and bacteriological (Escherichia Coli and other coliforms) parameters in the laboratory based on American Public Health Organization (APHA) standard methods. The mean pH concentration was 6.8 across all the locations, while the turbidity of the TW ranged from 2.39 NTU at SL4 to 3.44 NTU. The chlorine ion (Cl-) of the SLs ranged from 15.62 mg/l at SLs to 20.83 mg/l at SL1, the F3+ of the SLs ranged from 0.1 mg/l across all locations, the PO3 of the SLs ranged from 0.26 mg/l at SL3 to 0.28 mg/l at SL1 and SO3 of the SLs ranged from 0.13 mg/l at SL2 to 0.22 mg/l at SL1. All the parameters reported are within the WHO/NSDWQ limit except for the NO-2 of the SLs, which ranged from 6.47 mg/l at SL2 to 7.63 mg/l at SL1.
