keywords: Heavy metals, physico-chemical parameters, water quality
In the present study, some physico-chemical parameters and heavy metals content in water samples collected from three sources (wells, boreholes and river) at two different areas (Kente and Hospital Ward) in Wukari local government area were analyzed using standard methods in order to ascertain its quality. The study was conducted during dry season (2015) and rainy season (2016). The physico–chemical parameters of interest that were investigated include temperature, turbidity, suspended solids, total dissolved solids (TDS), conductivity, pH, phosphate, chloride, alkalinity, hardness, chemical oxygen demand (COD), dissolved oxygen (DO) and biological oxygen demand (BOD) while that of metals were cadmium, lead, arsenic, iron, copper, mercury and manganese and the results compared with standard values as prescribed by Standards Organization of Nigeria (SON). The results of the study revealed that the mean amounts of metals analyzed were within the allowable limit as set by SON except that of lead in all water samples from the river irrespective of the season. Most physico-chemical parameters results fall within SON guidelines and some were above the SON limit. In conclusion, the results indicate that seasonal change did not bring significant alteration in the parameters analyzed.
