Abstract
The water quality of selected boreholes in Oredo, Egor and Ovia North-East Local Government Areas in Benin City metropolis was assessed in terms of their physical, microbial and chemical parameters. A total of nine water samples (three per local government) were collected from randomly selected public boreholes in the month of July, 2018. The physicochemical parameters determined and values obtained are as follows: Electrical conductivity ranged 12.85 to 101.94 µS/cm, Temperature 25.00 to 25.01, pH of 4.32 to 5.55, TDS 0.67 to 4.00 mg/l, COD 3.20 to 16.00 mg/l, Turbidity 1.14 to 5.38FTU, Cl- 106.50 to 426.00 mg/l, SO42- 0.41 to 2.87 mg/l, TSS 0.33 to 1.67 mg/l, TS 1.33 to 4.33 mg/l, NO3- 23.73 to 41.48 mg/l, Mg 0.03 to 0.61mg/l, Ca 0.10 to 0.41 mg/l, HCO3- 7.00 to 22.00 mg/l, Na 0.20 to 7.75 mg/l, K 0.41 to 1.20 mg/l, Mn 0.01 to 0.11 mg/l, Fe 0.01 to 0.02 mg/l, Zn 0.01 to 0.65 mg/l, PO4- 0.07 mg/l for all locations, while some metals like Cd, Pb were not detected. Microbial evaluation was done on the samples to assess the level of E. coli, coliforms and bacteria. The principal component analysis result extracted two components each from the three LGAs; In Oredo LGA, Factor 1 accounted for 84.9% while Factor 2 accounts for 15.1%. In Egor LGA, Factor 1 accounts for 51.1% while Factor 2 accounts for 48.9%. In Ovia North-East LGA, Factor 1 accounted for 59.0% while Factor 2 accounts for 49.0% contributions.
