The physicochemical parameters of seven different borehole waters in Oke-Oyi, Ilorin East Local
Government Area, Kwara State, Nigeria were assessed to determine it suitability for human consumption. The
parameters examined include temperature (28 - 29⁰C), conductivity (414 - 1603 μs/cm), pH (5.71 - 6.57), total
hardness (20.2 - 67.3 mg/L). The concentrations of heavy metals determined are Zn (0.010 – 0.022 mg/L), Fe (0.002 -
0.120 mg/L), Cr (0.075 - 0.12 mg/L), Cu (3x10-4 – 2x10-3 mg/L), Co (0.01 - 0.26 mg/L) and Mn (0.082 - 0.94 mg/L).
There was no lead detected in two of the borehole water samples while those detected have low concentration range 1
x 10-5 – 6 x 10-5. The results of physicochemical parameters obtained are within World Health Organisation (WHO)
limits except for the pH that is slightly lower and the conductivity of OKY 1 that is slightly higher.
