Water samples were obtained from eight (8) different boreholes in Itu local government area, South-South of Nigeria. These samples were treated and analyzed using standard methods for their pH, temperature, turbidity, electrical conductivity (EC), total hardness (TH), dissolved oxygen (DO), biochemical oxygen demand (BOD), iron (Fe), zinc (Zn), copper (Cu), lead (Pb), cadmium (Cd) and nickel (Ni) levels. Mean levels of all the parameters determined in studied groundwater were within their safe limits except lead and cadmium. This study revealed that concentrations of Pb and Cd rendered water from the studied boreholes unsafe for human consumption considering the toxic nature of these metals. Variable correlations were observed among the studied physicochemical properties of water. Pollution index analysis also confirmed the hazardous nature of lead and cadmium in groundwater from studied boreholes. Proper treatment of studied boreholes to eliminate these toxic metals has been recommended as prolong consumption of this untreated water may eventually result in health problems associated with pb and Cd toxicities.
