Abstract
Groundwater is now the major source of domestic, commercial and industrial source of water for residents of major cities all over the world. Residents in Yenagoa metropolis also depend heavily on boreholes water for their daily needs. The aim of this study was to assess the physicochemical and heavy metals characteristic of selected boreholes water in Onopa, Azikoro and Agbura communities of Attisa Clan in Yenagoa metropolis of Bayelsa State. Parameters analysed include: EC, TDS, TSS, TH, pH, TA, Cl, F, NO3, SO4, PO4, DO, COD, BOD, Ca. Heavy metals include Mg, Fe, Cd, Cr, Cu and Pb. Evaluation of WQI and HPI was also undertaken. Results show that all the physicochemical parameters were within the standard limit of (WHO). WQI evaluation revealed that all the water samples have excellent quality for drinking with respect to physicochemical qualities. However, HPI evaluation revealed that the waters are not safe for drinking with respect to heavy metal pollution significantly influenced by high Cadmium concentration in most of the samples. It is concluded that Cadmium is a heavy metal of concern in the study area and that regular monitoring of drinking water should be undertaken in order to protect public health and wellbeing.
