Abstract
Drinking water quality monitoring is important for the protection of public health and wellbeing. In this study, four physical parameters i.e. EC, TDS, TSS and TH, ten chemical parameters i.e. pH, TA, NO3, SO4,PO4,Cl, F, DO, BOD and COD, nine heavy metals which include, Mg, Ca, Fe, Cd, Cr, Cu, Mn, Pb and Al were analysed in nine boreholes water samples collected from, Igbogene, Yenegwe and Akenfa in Epie District of Yenagoa. The physical, chemical and heavy metals parameter measurements are within the limit recommended by the Nigerian Drinking water quality standard and WHO except for Cadmium at Yenegwe point 1 where concentration was 0.004mg/l > 0.003mg/l the recommended limit.WQI evaluation showed that water quality of sample collected at Yenegwe point 1 and Akenfa point 1 are unsuitable for drinking, while water collected at Igbogene point1 and Akenfa point 3 exhibited water quality that is poor for drinking. HPI evaluation revealed that water sample from Yenegwe point 1 and Akenfa point 1 have HPI of 112.64 and 107.46 respectively which exceed the critical value of 100. It is recommended that boreholes water quality should be monitored regularly in order to protect public health.
